Be aware of chain line issues on a Dahon folding bike, with a tight 130 mm rear hub dropout spacing and short chain stays; a 44t dished chainring large enough to clear the motor reduction casting with 10mm+ offset is the smallest I can get away with, and a chain guide mounted to the 35mm arching frame member from the bottom bracket shell to the main frame member, ahead of the 40mm seatpost tube, still seems like a good idea. The VD18MT display is excellent; easy to adjust speed limit and pedal assist levels directly from the display. Plus, customer service from these folks is beyond excellent. Review: Pleased with purchase - Purchased the 750w motor with the EKDO1 display, and 20 Ah battery. I put this setup on a Specialized Sirrus 4.O bike. I am a 215 lbs rider, and over the course of 6 rides with a total 5146 ft of elevation gain, I got 118 miles on a single battery charge. The mileage and elevation gain was measured by the "Ride with GPS" app. on my phone. (The bike's display indicated 128 miles for the same 6 rides). I was trying to maximize the battery life so I stayed in PAS levels 1 and 2 exclusively. I comfortably averaged 14 MPH on these rides. PAS 1 and 2 easily handled all hills. The conversion kit comes with no instructions, but all the information you need to install is shown in the information on the desertcart webpage for this motor. Look this information over VERY carefully before you purchase. make sure you understand everything. Be careful to get the correct size chainring, and that your bike has clearance for this size chainring. Chainring size is determined by the number of cogs on your rear hub. Make sure you know your bottom bracket type and size before you order. I suggest you bring your bike into a bike shop and have them remove the bottom bracket. They have the necessary tools and It will only take them a few minutes. They can confirm what type and size the bottom bracket is. The total weight of the bike, motor and battery is 45LBS. All of the connecting wires are long, and after all connections are made you will probably have a lot of excess wire you will have to zip tie to the bike. There are a few small zip ties that come with the bike, but I suggest buying a package of larger zip ties as you will need a lot of them. Installation really isn't that difficult, although it may appear so at first. There are some installation videos out there. The battery mounts to the water bottle holders on your bike's frame. These holders are designed to hold a water bottle and not a 10 lbs battery. I did mount the battery to the water bottle holder, however I also purchased some 24" heavy duty zip ties to zip tie the battery to the frame. I don't know if this is necessary, but it was added peace of mind. The kit comes with a front light, but no bracket to install it on the bike. I already had had a better light I had intended to use, so this didn't bother me. The finished setup rides very smooth and quiet. I now have about 400 miles on it and I'm very happy! ## Features - Complete Accessories:This Bafang Mid-drive motor BBS02B/BBS-HD kit includes most necessary electric bike accessories, such as brake lever, chainwheel,thumb throttle,speed sensor, headlight , bottm bracket removal tool,Battery(optional) and LCD display(optional).You can choose different parts according to your needs to DIY your own beloved electric bicycle - Universal Fit for Most Bikes:The adaptable BAFANG 500W/750W/1000W mid-drive kit seamlessly integrates with bottom brackets 68-73mm, 100mm, and 120mm lengths and 33.5-36mm inner diameters, adhering to JIS norms.

I'm a heavy guy, but even so it has a decent amount of go power. It feels natural to use while peddling. As a disclaimer, this review is after a single day of use. Installing the conversion kit was somewhat challenging for me. I'm reasonably handy, but had no previous experience doing this type of thing. If you already know how and have the tools to remove pedals, cranks, the bottom bracket, and possibly the chain from a bicycle I imagine this will be a pretty easy conversion for you. If not, here's some info that might be helpful. You'll need to figure out what kind of bottom bracket your bike has and get the tools needed to remove it. My conversion kit came with a crank puller and what I THINK is a 20 spline bottom bracket removal tool. Mine is apparently a cup and cone type, so in my case I had to buy a 3 notch hook spanner and a 36mm box end wrench. The supplied crank puller did work for me. I also removed the front gear shifter since it's no longer needed and was worried it might get in the way. I needed a bike chain removal kit to completely remove that. Though I'd recommend getting a bike chain repair kit in case you accidentally completely remove the pin I like did, as they'll come with master links. You'll probably also want to make sure you have a metric wrench set with a good variety of sizes, same with metric allen wrenches. I think you could get by with pretty much any single size Phillips head screwdriver, I'd recommend but a variety of those as well. I did a downtube style battery. My bike did not have the water bottle eyelets so I also needed to get an ebike battery anchor bracket mount. I imagine that's probably not a common problem. But they exist if you need it. As mentioned in many other reviews, the instructions provided contain very little information. I found a video of how to remove pedals, cranks, and my style of bottom bracket. And a video of how to install this conversion kit. Made a few minor mistakes here and there, but overall not too difficult once I had the tools I needed. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/670898918-bbs02b-bbs-hd-500w-750w-1000w-mid-drive-electric-bike](https://www.desertcart.hr/products/670898918-bbs02b-bbs-hd-500w-750w-1000w-mid-drive-electric-bike) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-16*
