Blusmart Wireless Bike Speedometer Multi-functions with Clock Stopwatch Thermometer Waterproof Odometer of Big LCD Display Backlight

This works exactly as expected. As others have noted in some of the negative reviews it does make a rattle like something is loose inside (imagine the sound of a grain of rice bouncing around in a small plastic shell.) While mildly noticeable, this does not bother me at all as there is enough other sounds while I ride to not find this distracting in the least. Other than that I have absolutely no complaints about this little computer, and for $16 that complaint is very easily overlooked.It was incredibly easy to set up, and seems to provide quite accurate results (I have taken it on rides where I know the exact distance and it's almost dead on - although proper calibration is crucial for accurate results.) The display is easy to read while moving and can be easily set to cycle through various stats about your ride as you go. I like that I can look down at any given point while I'm riding and see how fast I'm going, how far I've traveled, my avg. speed, my max speed, and how long I've been moving (and just as an FYI the trip clock stops when you do so you're not clocking statistics if you take a break for water or food.) Also, a touch of either button will temporarily backlight the screen so if you're riding at dawn/dusk when it's a little harder to see this will provide a glimpse at your stats more clearly (it does not stay lit up however, so I would imagine this would not be the most ideal fit for night riding.)I've put a few hundred miles on this already and I couldn't be more pleased. I don't know if it's fully submersible in water as the pictures seem to indicate, but I have sprayed down my bike with a hose after a couple of short rides on a dirt road after rainful and the computer is still working great so I can only assume rain would not pose any issues for it.While I'm sure there are nicer bike computers out there, for the price this is hard to beat. I would recommend this product to anyone wanting a bike computer that works but not wanting to shell out a bunch of money to get one.

This bike computer is a good buy for the money. $14 isn't cheap, but it is less expensive than the local bike shop.The computer works fine - I particularly like that the numbers are large, and there is a 'scan' feature that rotates through speed, average speed, distance, etc. A really nice feature is that there is some mechanism inside (little steel ball I suspect) that rolls as soon as the device is moved, waking up the screen. That's nice. And a feature I had not expected is that the timer automatically starts and stops. That is very handy, as I almost ALWAYS forget to start those sorts of thing.The setup was straightforward, but a bit tricky. Just gotta make very sure you have the magnet mounted such that it moves within about 1/8" of the wireless sensor. That wasn't difficult, but took a bit of trial and error to find the right spot. No worries, it added about an extra 3 minutes to the otherwise fast install.

This bike computer arrived quickly (it is small so was delivered to my mailbox..don't wait for it to hit your porch.). It was easy to install. Comes with batteries. I purchased this computer to add to my girlfriends bike. After handling this unit for a short time, I have decided to get rid of an expensive computer on my bike and replace it with one of these. It is very strait forward and simple to use. No need to keep the instructions.Installation is a breeze, I used a butter knife, and a phillips screwdriver.

Simply fantastic. I was looking for a simple no-frills speedo+odo meter for my bike and ordered this with a little hesitation. I could not have been happier with this product. Took about 5 mins to install. Has been working perfectly well for month than a month and about 400 miles of riding. The error in calculation is < 0.1 miles over a 20+ mile trip when compared to GPS on my phone.If you are looking to just measure your speed and distance primarily and are not looking for anything extravagent, this is the best.

Yes! This is great!, fast delivery (before the date Time they gave me). Product excellent! A lit confused to the begin to set up, however is a question of minutes. I used twice and tried km and miles, I can't believe my eyes that right it is. Very easy to install, less than 10', if u are the person slow skills I recommend u to watch some YouTube videos abt installation, (so easy). And so easy understand the functions after use it the first time. I'm really so happy to discover this, cheap and good. This beats "sigma", "cateye ", being this brands the best on market. Bluesmart nothing to envy to those brands. I hope it helps u to decide it I recommend it at all!. AMZL-US amazing carrier too, something new I discovered.

This is a great little computer. I got back into cycling after heart surgery and wanted something to keep track of my miles and of mph. This does that plus some. Easy to install, just takes a little fiddling to get the sensor and the magnet to line up, no big deal. Can't beat the price either!

This is a great bicycle accessory. It is easy to read and use. It takes a little time and patience to set it up, but once it is set up, I have not had to do a thing. I like that you can reset it every day so you know exactly how far, what speed, and how much time it took for each ride.

Works great so far. The rattling of the steel ball in there is a little noticeable at slow speeds but for me it is worth it to have a auto start and longer battery life. Once you get going you don't notice it at all and you can't beat the price. Install instructions are actually really good and it includes all the ties and more that you would need to get it set up. I haven't been caught in the rain yet so I don't know about waterproof but all the parts seem really well made and look nice.
