Mid Drive Kit 750W 1000W 500W BBS02B BBS-HD Electric Bike Conversion Kit 48V 52V Ebike Conversion Kit for 68-73MM Mountain Bike Road Bike with Battery and Display(Optional)

This kit worked great on a 2021 Giant Talon medium sized frame. I did have to go with the lekkie 40T kit to get a good chain line. This was my first build. The motor has plenty of power. My biggest recommendation is to make sure you do your research that you have a compatible bike to put it on. Will work on most but certain bikes work better than others. The installation was very easy, the devil is in the details to get it perfect!

After >2,000 miles, using the 750 and the 1,000, this is a tough review because of the many elements involved and must start by saying that these motors are a little marvel. It pushes well and responds very well to the cadence and push of your legs, for up to 8 hours in 1 and 2, while can run like a motorcycle in max (7 to 10) with no effort and drain the battery in 10 miles. I have crossed rivers up to 3 feet deep and opened the engine dry. Battery however failed with water and could not recover. Some connections with sensors may be lose or faulty and this is a mystery I haven’t solved so, will have to change cables to see if is the connection or the controller.

I love my Bafang Conversion kit! The order was very quick and simple. I got my kit within two days of me placing the order and instantly assembled the kit on to my bike . So far this kit is amazing and very easy to install. I would definitely buy this kit again but just have to say that the quality and price of this kit is most definitely reasonable compared to other kits on the market. I would say the only downfall is the Manual/Diagrams that the kit arrives with, it is very vague and not precise. YouTube was a better option for me then reading the manual as well as tuning my ride to go faster then the legal mode. -Pricing is affordable -Quality is Great -Install is easy (YouTube) -Kit is very fun and reliable -Also Very Quiet too when I ride around

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 Amazon 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!

I added this mid drive kit to my old Yuba Mundo cargo bike, and I have been very happy with it so far. Installation was very straightforward, and only took me a couple hours. All the tools for bottom bracket and crank removal were included. This was also the best price I found for the kit I wanted, and the whole kit was shipped and received within a couple days of ordering, and was exactly as I customized. My old bike really flies now!

La qualité est au rendez-vous et la bonne fonctionnalité aussi. Des outils utiles sont fournis avec le kit. Tout fonctionne bien et je recommande ce kit avec la batterie, prix plus compétitif qu'en achat isolé.
