Sunny Health & Fitness Heavy-Duty Indoor Stationary Exercise Bike w/49 LB Flywheel & 275LB Capacity, 4-Way Adjustable Seat & Multi-Grip Handlebar for Cardio Training & Cycling workout at Home

If you've had the BANGING issue with this bike, skip to the end for notes on my fix *********************************** Initially I had looked at buying the Peloton bike because of their really great app but ultimately decided it was not worth the investment considering spinning was completely new to me. My intention was to use this bike in conjunction with the Peloton app ($12/mo). So far I am very satisfied with my purchase. Delivery - I paid just under $300 for the bike which included shipping. Which is really unbelievable in and of itself. I'm not sure how the UPS guy even got it up the stairs to our landing because the box weighed over 120 pounds. This bike is *very* sturdy. My first concern was that for $300 you would get a rickety piece of garbage. Not the case. Peloton charges $250 just for shipping. Assembly - honestly, the actual assembly part took about ten minutes. But it took 10 minutes to get the box into the basement, 15 minutes to unpack the box and unwrap all the parts and another 5 to sort of gather everything together. There are very few actual pieces, like I said, the bike is very sturdy when put together. "Add ons" / changes - I made a few minor additions to the bike to improve the use. 1 - Added a pair of Shimano SPD pedals ($35). These are fantastic pedals, I *highly* recommend them and they work great on this bike. Took only a few minutes to swap out. So far zero issues with the pedals. Please not if you have never used clip-in pedals before, you will need bike shoes with SPD cleats on them to use. https://www.amazon.com/gp/product/B003ZMDK5C 2 - Simple ipad holder for the handlebars ($20). I have a beat up, cracked-up old ipad4 that I planned to use on the bike and this clip works perfectly. https://www.amazon.com/gp/product/B00D5YTO5K 3 - Bike mat ($30) - perfect size, seems to work great so far. Its a mat, nothing fancy. https://www.amazon.com/gp/product/B001THTUAO 4 - Wireless computer from spinning.com ($65) - I tried two of the Cateye models and just did not like how small they were and one I could not get to work with the spin bike. The spinning.com computers are made to work with their brand spin bikes but seems to work great with this model. Look I am not an engineer, I'm not going to guarantee that these are insanely accurate and are really only made for their brand bikes - but its worked fine so far. I was most interested in something that was wireless, would display time/cadence at the same time and that was easy to read. So I spent $150 or so on other options and am completely happy right now with my setup. ***Notes on use with the Peloton app*** - As I said, I bought this bike specifically to use with the Peloton app. I am very impressed with the app so far. They have dozens of live classes every day or thousands of on demand ones. The app has a pretty simple filter that allows you to search/sort by class type, time, instructor etc. I wish there were a couple of minor tweaks - like letting you save your favorite rides into some kind of favorites menu - but so far I am very happy. The ipad version of the app is $12/month whereas if you have the Peleton bike they charge you $40/month. Even at that price, IMO, its worth it since I have been using it every day. Spin studios in the DC area can run upwards of $175-200/month for unlimited rides. ***Notes on FIXES or things that might break*** - As has been noted in other reviews there seem to be a couple of quality control issues, both of which I ran into. 1 - Squeaky resistance pad - Definitely happened to me over the first week. I used it every day and it seemed to get worse. I bought a $7 can of liquid graphite spray off Amazon and I gave it a few shots, it cleared right up. I could see just giving it a shot every couple weeks. Nothing major here, very easy fix. 2 - That BANGING or knocking on every peddle stroke. - If you've had it, you know what I'm talking about. It sounds like the bike is broken and goes BANG BANG BANG on each peddle stroke. I emailed the company and they sent me a PDF with pictures about making some adjustments to the belt with the two adjustment screws on the front. I spent @ 20 minutes screwing around with it and eventually it did stop. It was a pain in the neck and very annoying to have to deal with but it did finally stop. - Take the belt cover off - screws on the two sides and bottom - take the big side nuts off from the fork - adjust the screws I circled in yellow. Experimentation and patience required! Look, this bike cost $300 shipped. For that price, I had a reasonable expectation that the bike would not be perfect and would probably need some adjustments. If I wanted to buy the $2000 bike with $250 shipping charge, I would certainly have expected a higher level of quality. But for the cost I am very happy with my purchase.

Delivered quickly and well packed. Exterior or package showed evidence of a drop on one corner, but only apparent damage was a significantly deformed packing strut (intended to be discarded). Instructions for assembly and adjustment were complete and useful. Insertion and adjustment of seat and handlebar columns required dead-blow hammer force, but as adjusted are completely stable -- no wobble or loosening, Based on other review comments, I replaced the supplied saddle with one I knew to be comfortable for me, along with the supplied pedals with clipless pedals. I also installed standard wired bike computers, using alternate spoke magnets and sensor attachment methods (double sided tape, longer zip ties and wood spacers). Time, cadence, speed, distance and other statistics are now available. As I have only had the unit a short time, with about 15 hours of use, long term durability is unknown. Operation has been excellent. Entire unit is rock solid, operation is virtually silent, and resistance device works well. REVIEW UPDATE - after four months use (approx. 100 hours/2500 odometer Kilometers). The five star rating remains unchanged. Details on bike computer installation: Most bike computers are based on a clock, micro-switch to sense magnet attached wheel & or pedal crank, and memory of a manually input wheel circumference) with statistics reported calculated from these three elements, As I wished to have continuous display of speed and and pedal rpm as well their session averages I chose to use two separate single sensor computers. Wheel circumference setting input to yield speed was the measured flywheel circumference, 1460 mm (57.5 inches) about the same as for a 409 bike tire size. Wheel circumference setting on input to yield pedal revolutions was 167 mm (correct conversion factor is actually 1667 mm, but because of specific input limits of computer used, the lower amount was used. Resulting "speed" mode display is 1/10 or actual crank revolutions per minute, with two displayed digits after the decimal point (for example, 100 RPM is displayed as speed of 10.00). The actual computers selected were Sunding model SD 558A because of display size and price (actually paid less than $5 for both, but currently available on internet for about $12 a piece). Their sensors are wired. Virtually any available bike computer could be substituted, but specific mounting and setting procedures might be required. The computers with their display screens mount on the center of the handlebar using the supplied mounts and zip ties. Because of the cycle frame configuration, sensor mounts required fabricated shims and longer 11 inch zip ties (the originally used tape eventually lost its grip). The shim for the RPM sensor is approximately 1/4 " X 4 1/2" x 2" with 2 drilled holes in one end to secure the sensor to the shim with supplied zip ties, and two 11" zip ties around the upper belt guard and shim secured it in place . 3 11" zip ties secured the sensor wire to the frame between the sensor and its display head. I replaced the supplied wheel magnet with a .75" round ceramic magnet attached with only its own force to the right pedal crank arm at the inside of the pedal. The shim for the speed sensor is approximately 1 3/8" X 5/8" X 4" 2 holes drilled in one of the 1 3/8" sides to secure 11" zip ties to the left front bike fork and 2 holes opposite them to secure the sensor with two supplied zip ties. An additional 2 11" zip ties secured the speed sensor wires to the bike frame between the sensor and its display head. I replaced the supplied wheel magnet with a .75" round ceramic magnet attached with only its own attraction to the flywheel, just below its rim. The resistance device works well, with proportionate increases in resistance with knob turns, no noise or vibration and no odor. I did spray the resistance pad with silicone lubricant before use and again after about two months use when a minor vibration had developed, I assume this will be a normal maintenance requirement, a two second burden I can live with. I contacted Sunny Sports and Fitness at their customer service web address to determine where cycle model specific parts could be obtained. A response arrived the same day that they could supply my needs (a resistance pad assembly and seat tube sleeve plastic sleeve). cost incl. postage was $12.50, which I consider a bargain. The water bottle holder presented two problems to me. In its original position, my right knee would occasionally bump the holder as I performed jumps (I am not yet as smooth at these as I should be). Relocating the holder to the front of the fork frame and reattaching with 2 11" zip ties solved this issue. The 28 oz. water bottle I use did not slide into the holder easily. Slight bending of the top of the holder front and rear wires improved the bottle fit.

I really wanted to give this 5 stars, but I can't for a couple reasons. I'd really rate this like a 3.75 star. This bike is sturdy and well put together. Easy to assemble, and for the most part rides like a dream. It's fairly quiet due to the belt drive, and the adjustments for the saddle and handlebars are very good - but not great. (Being shorter, I would prefer a bit more range of adjustment in both). The near fatal flaw in this bike is the belt adjustment. Holy cow is it aggravating. It must be how the belt works with the flywheel. The tighten/loosen adjustment is ALL over the place. When you are in the middle of a ride and want to adjust looser, you turn to minus, and it might just get TIGHTER for a bit. And vice-versa. Sometimes turning it seems to have zero effect. Then you wait, and turn it more, and then it has too much effect. My guess is that the friction with the flywheel has different effects depending on how tight it is, and how hot it is. This makes mid-ride adjustments aggravating. It's a near fatal flaw in what is otherwise a very enjoyable bike. So be aware if you get this, you are going to have to fiddle a lot with it during the ride. Sometimes adjusting the opposite way to get the results you need. Sometimes adjusting both ways until you can get it where you want. And there's no settings view for the adjustment. The bike can't remember a setting. It's all very arbitrary. I guess for the price, this is what you get. I will also say the seat is very uncomfortable. Trying to find a solution for that. Bottom line is I would recommend this bike if you are on a budget like me. It IS working for me as a cardio workout. It's just that the experience could be better.

This Sunny spin bike is very similar to the bikes we had at the gym when I first started spin classes there. 12 years ago. They upgraded to some more glitzy bikes, but I continued to just monitor my heart rate with a chest strap and cell phone app. Which is my go-to with the Sunny bike at home. If I want to participate in a group session on the bike, there are plenty available online and it is easy to find a way to attach your phone to the bike. Now I just put on the radio and watch my heart rate go up. And I can hear the radio better now since this bike is so quiet (I had been using a cyclops wind trainer before which was fine, a little noisy, and not the level of workout that this bike provides) Personally , I have no need for anything fancier than the heart rate monitor/fitness app, but there are a lot of reviewers that purchased add-ons that provide a 'Peloton-esque' experience. Even with the expense of the add-ons, you can't beat the price and quality of this bike. A lot of reviews and questions I read before purchasing this bike indicated that some folks are a little naive about what is required to use and maintain a good spin bike. When I attended spin classes at the local gym the bikes developed the kind of issues reviewers here are complaining about. So the bikes had to go to maintenance and were returned. They were used a LOT, so not surprise there. Same goes for this bike, if you purchase and use it a lot. However, if you set up and maintain it properly, including fixing it when it thumps or creaks, it will pay you back in a great spin. Sunny has videos and documents online to help you. My bike was a little thumpy at first. Usually a pedal problem. You can just tighten up the pedals more, but I recommend using a threadlocker on the threads when you screw the pedals in place. I used harborfreight semi-permanent threadlock. Another reviewer used loctite. I also changed out my pedals to use shimano pedals that allow me to use either clip or clipless. If you prefer clipless, you might go that route. Either way, tightening the pedals with threadlock eliminated the thump immediately. I have not had to tighten the crank, but I see this as something that may be necessary down the line. There are videos on doing that with bikes in general online. The other item you really need to check when you first set up your bike is the leather brake pad. It will likely need to be lubricated. Some folks complained that the bike smelled like something burning. My guess is that they never lubricated the brake pad. If you bike is new, this is as simple as putting a few drops of 3 in 1 oil on the flywheel where the brake rests with light resistance, rotating the wheel and letting the oil soak in. The pad will get considerably darker in color. If you have been riding it a while, you might need to pull the pad gizmo off and rough it up a bit for the oil to absorb. That requires removing one screw. Not rocket science. One of the beauties of this spin bike is that its design is relatively simple - not all those bells and whistles that potentially go bad. That also makes the great price point of this sturdy piece of equipment, especially the heavy flywheel that you wouldn't find in an inexpensive bike and that makes this an amazing spin bike.

Update: I've had this bike for a little over a month, and I still LOVE it. Pretty much ride it every day. I've started using it with the Peloton App, and added the Wahoo HR monitor and cadence meter. I'm completely in love with this set up! Someday I might upgrade to a bike with a resistance meter, but I fully intend to ride the heck out of this Sunny as long as I can! *** I seriously LOVE this bike - great purchase, and amazing quality. I didn't expect it to be nearly as nice. A couple of months ago, I went to my spin class at the gym, only to find that it had been cancelled at the last minute. I have a hard time making my schedule work to get to class, so I was pretty disappointed. But I don't like to ride outside in the cold (I'm seriously a wuss), so, rather than leave, I pulled up a spin class on YouTube. I got lucky and randomly landed on Paul Ryman's 40 minute class on Global Cycling Network - this class is actually 45 minutes long, and is the best video I've found so far, so if you're looking for a good video, that's a great one. Anyway, I hopped on the bike at the gym and did the YouTube class, which then got me thinking. If I had a spin bike, I wouldn't have to constantly try to work my schedule around the gym schedule, and I wouldn't be stuck riding my road bike outside in the winter cold. So I started researching. I wanted a belt driven bike, and something that would not be a source of constant disappointment. I liked the idea of the Peloton bike, but I already have a TV on the wall where I work out, and thought maybe the screen might be annoying. I also didn't want to pay that much for a bike. I read tons of reviews on as many belt driven bikes I could find, and liked the idea of the 49 pound fly wheel. After making my purchase, I can say that the weight of the flywheel is a major point in favor of this bike. The weight makes a fantastic ride - I can really control the resistance well, and there's just something about it that makes the ride super smooth. The construction of the bike itself is also fantastic. I don't even want to say "for the price," because I feel that is a completely unnecessary qualifier here. The frame is steel, and I don't have any wobbling or loose bolts. It's easy to put together and move around once it's ready. It's a great size - my workout room is a small den, and the bike doesn't take up much room at all. Long story short, I really, really love this bike! I could swear it's better quality than the ones at my gym - maybe they're just worn out, and I know they don't do maintenance on them like they should. BUT - the Sunny bike is SO smooth, and being belt driven, it's quiet. My husband tells me he can't tell when I'm spinning in the next room over. There's a little bit of a woosh noise from the resistance pad (which is leather, btw), but short of buying a magnetic resistance bike and shelling out A LOT more money, this is the very best choice I could have made. I haven't had any of the banging issues that other people have noted. I've had the bike now for a week, and I've used it every day. It has already made my life better! I spin in the morning before work, and have tons of energy all day. I can't wait to go on my next actual road ride, because I can tell my fitness has already improved. A couple of things to note about fitting this bike. I'm a 5'2" 134 pound woman. My inseam is borderline for this bike as is listed in the product description - barely 29 inches. After I clicked the Buy button, I really worried about what I would do if my legs weren't long enough. But after getting it all set up, I probably have about an inch to spare. The seat moves forward and back as well as up and down, which is, of course, integral to avoiding knee injury. The handlebars adjust in height, but don't adjust forward and back, which I knew from reading other reviews prior to purchase. It is a slight bit longer of a reach than I would prefer, but it's completely dealable and not really an issue. The seat is not as uncomfortable as I expected, but one of the reasons I chose this bike over some of the others is because I was able to swap out the stock seat for my favorite seat. Some other spin bikes don't give you that ability. I also changed out the pedals for SPD's. The pedals that come with the bike are fine, though, if you're used to using cages (straps) or want to ride flat foot. The cranks do seem a slight bit wider than I'm used to, but so far I'm not experiencing any pain or issues. All in all - this bike is a great buy. Sturdy, smooth, easy to assemble - and the price is unreal. Super stoked that I made this purchase!

I received my bike yesterday and immediately noted the box took a little bit of a beating. There was one hole punched into it, and I was dreading what I'd find inside due to some "horror" stories of other's whose bikes arrived with some damage - fortunately everything seemed fine. When you start the process of unboxing it, you may do like I did - set the box right side up and begin to pry open the flaps. As soon as you get that top flap pulled apart - you'll find noted in red ink that the recommendation is to open from the bottom - then set the box right side up and pull the box off. I did this whole process by myself and let me tell ya, the box is heavy - it's not something you can just "move anywhichaway" - so two people would be my recommendation. Once you lift the box off you'll see why box appeared deceptively small - it's because pockets have been cut into the styrofoam for all the parts - the bike itself is one complete unit which you'll work on attaching said parts. Who ever came up with this packaging system - I hope they got a raise. The two cross-members that stabilize the bike will be your first order of business. My advice (again I was working alone) would be to place the front cross-member in position first because that dern fly wheel is 49 lbs. Then place the rear cross-member in position - ensure your holes are all lined up and hand-tighten all four allen-head screws - then go back and snug 'em down with the supplied allen wrench. After that it's just simple matter of attaching the bottle holder, pedals, seat, and handle bars. The pedals are marked "left" and "right" with a note that the left pedal screws in counter-clockwise. Everything went together well with no glitches. The pedals do come with a toe box (I guess that's what they're called - heck if I know - I'm a noob) and straps. They work well, but I think it's something that I'll replace in the near future. I watched a video on how to adjust the bike (handle bar, seat height) then hopped on and took if for a spin (pun intended) The operation was smooth, quiet, and as a whole the bike felt rock solid. I bought a "tablet holder" for the handle bars got it mounted - attached my ASUS, grabbed my head phones, booted up ITUNES and peddled to my collection of top Polka music of the 50's. Nah, not really. I will say though that by my fifth AC/DC song, I was sweating something fierce and my headphones were becoming a problem staying on - I'm bald so that could be the problem. My feet felt solid in the toe boxes and on the pedals in general. I was able to really torque my legs pushing and pulling and getting that burn - which by the seventh song (Rolling Stones Gimme Shelter) I said "NO MAS" got off and crawled up the stairs all the while taking note just how out of shape I am. I bought this bike mainly because I'm getting a little bit of a gut and I want to get back into shape. The reviews I read (no not Amazon reviews) rated this product as really good for the price. In fact some of the reviews rated this bike above those that cost a lot more. I'd recommend this to anyone without hesitation.

Received this bike today via my friendly UPS guy. It was easy for me to setup; the tools are included and the instructions are easy to understand. It is a big package and heavy, so I can see how it would be cumbersome to get it out of the box. The bike is packed really well and I didn't receive a damaged product even though I could tell that the box had seen some action. Total unpacking and setup probably took me about 45 minutes. After I got it setup, I referred to a great YouTube video that explains how to "calibrate" everything so I feel like I did everything properly. There's tons of information on the web about spin bikes and I found nothing but positive reviews about this model. I consider myself a casual bike rider and I've never been to a spin class. In fact, I had never even heard the term "spin bike" before. My background in bikes is with mountain bikes and the last bike I had was about 6 years ago. I'm really a runner so I load up some hard-core-testosterone metal on my music player and run/walk about 2 miles in the wee morning hours. I've been contemplating on a stationary bike or treadmill for some time now and I finally decided to go ahead and get something. I plan to alternate this with my morning runs and have an alternative low-impact workout. I hate having to deal with bad weather or dogs or nosy people. So having this bike can give me some power over my workouts and will let me stay away from gyms, which I utterly loathe. I usually get distracted and it takes away from my workout. And I don't have to pay a gym membership to use the aerobic equipment. Also, I don't have to deal with dishonest gym owners and employees locking me into 20 year gym memberships. This ends all of that for me. I'm a big guy at 6'2" / 220 lbs so I was concerned that I wouldn't fit or it would be uncomfortable. That's not the case. I have plenty of room in the leg department and I don't feel cramped on it. I've got plenty of stretch for my legs and I can still go up on the seat a few more notches. The handle bar post could go up one more notch for me but it's nothing so serious that I want to return the bike. I'm worried about the belt breaking and not being to able to replace it, but after a little research on the web it seems that the belt is a standard size belt (5PK520) that you can possibly purchase at an auto parts store. It looks like the belt housing can be removed with a Phillips head screwdriver. The frame is really solid and doesn't move or wobble. The seat is hard and uncomfortable but it wouldn't be hard to replace it or get a cover. I took the shoe harnesses off and just plan to use my running shoes. This thing is really quiet. I can see using it in an apartment or even a dorm room. I wanted a bike that I could ride at 3 am with a person asleep in the next door room and I wouldn't bother them. I think this will do the job. Overall I'm pleased with this bike. I was going to get the cheaper chain version by Sunny but after reading the reviews and doing some research on the web, I decided to spend the extra 100 bucks and get this belt drive version. This is easily a great bike for someone who is new to the spin bike world. Ride on!

**Update after having bike for about five weeks -The bike is still working very nicely. I have noticed the resistance knob is not always consistent in how much resistance is added/removed. Overall the bike is still riding well and is quiet, no problems with noise or otherwise** I am giving this bike five stars after assembling it and using it for less than a week. I'll come back and revise this review if I have further experiences/thoughts that may be helpful to others. The five star review is based on value for money. I bought this bike to use with the Peloton App. I have had the bike assembled for three days and have done four rides so far. I am really enjoying it and feel more motivated to work out than I have in a long while. I am definitely sore and you will be too if you haven't cycled in a while. There will be a temptation to blame the bike but you would be sore even with a more expensive spin bike, trust me. Here are my initial thoughts: Assembly - My husband has some experience with bikes and was able to put this bike together in 20 minutes. I think on my own it would have taken maybe another 20 minutes but I am pretty bad with tools. Overall it was very easy to put together and Sunny includes all the tools you need which is very nice. Quality - The bike is much nicer than I expected. It looks and feels sturdy when you ride it. It pedals very smoothly, again, much more smoothly than I expected and on par with spin bikes I've ridden at the gym. Adjustability -- This is where the bike fails a little - the seat goes up and down and forward and back. That is nice but the holes are pretty far apart and would probably not fit someone very tall or very short. (Note that one nice feature is that you can adjust how the seat is tilted too, when first assembled ours was pitching me forward but I adjusted it to be more level and now it is fine). The handlebars go up and down but again the holes are pretty far apart. I also don't think the handlebars go high enough. They are fine for me at 5'6", but they will be very low for my husband who is 6'2". Data -- This is a no frills bike. You will not be able to do any at-home spin classes without adding a cadence sensor. I would recommend ordering either a spin computer or the Wahoo speed and cadence sensors. I went with the Wahoo cadence sensor (attached to the crank) to start with which displays on my phone. After a few rides I quickly decided I also need to know my distance and heart rate so I have also ordered the Wahoo speed sensor and the HR monitor. All of this costs around $120. You can also get a stand alone spin computer. For me I thought I'd prefer to track my work outs using my phone. Other accessories - You will likely want to get a mat for the bike. I also ordered an iPad holder and phone holder as well as a gel seat. I ordered Shimano spin shoes and I got clipless pedals. The shoes and pedals are kind of a luxury item compared to other accessories, but I definitely feel a difference in my effectiveness in the clipless . I ordered the wrong pedals for the shoes at first, - I ordered mountain bike shoes and road cycle pedals. Do a little research, my recommendation is to buy SPD moutain bike type shoes and compatible SPD pedals as I understand that mountain bike pedals are common at spin studios in general, so you could possibly also use them if you ever were taking a class out of the house. In any case, know that there is a difference between the cleat system between mountain bike type and road bike type pedals and shoes.

This is a great spin bike that will not break the bank! It was very easy to assemble, sturdy and quiet. The seat is a little hard but nothing a gel cover didn't quickly fix. I am 5"7 and do find the handle bars are a bit of a reach (they do not adjust on this model) and I have the seat as far forward as it will go. I was surprised by this so if you feel handlebar adjustment is important go a model up (maybe I just have short arms? LOL). But otherwise I am loving the ride. Using a fitness app for spin classes and wahoo cadence counter makes this a value packed spin bike that I am sure will have me crushing indoor workouts for years to come! The 49lb flywheel will give you legs of steel! :)

Very good

I think this is the best thing I bought. I love it. It’s very sturdy and easy to assemble. What even better no electric. So I can use anywhere. It is heavy so be aware. But it’s a really good exercise bike 10⭐️ £815 now I only paid £270 definitely bought at the rite time

GOOD

Alors comment vous dire...... cela faisait longtemps que me trottait en tête l'idée d'acheter un vélo de biking... après avoir effectué des recherches sur le site de Decathlon...tool fitness et fitness boutique et analysé les différents critères de considération telles que la robustesse des matériaux ainsi qu'une utilisation sérieuse de trois à cinq fois par semaine et également les différents réglages proposés tel que la hauteur de selle ainsi que la profondeur de cette dernière et également le réglage du guidon hauteur et profondeur qui sont des critères importants pour trouver une position adequate pour un pédalage optimum il était important de prendre en compte d'avoir une roue d'inertie avec un poids convenable puisque cette dernière a un impact considérable sur la fluidité du pédalage du coup mon choix c'est arrêter sur ce biking de marque Sunny trouver sur Amazon à un prix défiant toute concurrence et exceptionnellement bien noté à savoir plus de 6000 avis positif ce qui n' est pas rien étant moi même un pratiquant de salle de sport et ayant l'habitude de pratiquer le vélo biking je voulais absolument un produit proche des biking trouvé en salle et la honnêtement j'ai été bluffé par ce biking Sunny... à commencer par l'assemblage très simple des matériaux qui sont d'une robustesse et d'une qualité incroyable je n'en revenais pas de voir cela j'étais vraiment stupéfait pour un biking à 192 euros de voir une telle qualité avec une roue d'inertie de 22 kg et une stabilité du biking remarquable car très lourd et costaud le seul à priori que je pouvais avoir concernait le système de freinage qui fonctionne avec un cylinblok en caoutchouc surmonté d'une laniere en cuir épais comparer avec ce qui ce fait aujourd'hui à savoir le freinage électro magnétique (aimants) c'était vraiment ma seule inquiétude et peur d'être finalement déçu de mon achat mais rassurez vous ce biking est vraiment incroyable je retrouve exactement les mêmes sensations que celles du biking en salle de sport avec un pédalage extraordinaire alors oui effectivement vous ne trouverez pas d'écran digital avec compteur de calories.. vitesse et chronomètre ou encore cardio fréquencemètre qui de toute façon ne sont aucunement fiables sur tous les appareils de fitness... pour ma part je me sers de ma montre cardio Garmin et la j'ai toutes les informations essentielles cardio minimum maximum calories et j'en passe moi je préfère de très loin un biking dépourvu de compteur digital mais d'une qualité vraiment professionnelle de ce biking que je vais pouvoir conserver des années.,. je vous encourage à regarder les différents commentaires de ce biking et vous trouverez le commentaire d'une personne qui a travaillé dans le milieu professionnel des salles de sport et qui effectuait également l'entretien et les réparations des biking et il ne dit que du bien de ce biking Sunny voilà j'espère que mon avis pourra aider d'autres personnes hesitente sur le choix de leur biking pour ma part je ne regrette pas mon achat et je recommande ce produit à 200% vous pouvez y aller les yeux fermés.
