Mid Drive Ebike Conversion Kit 36V 48V BBS01B BBS02B BBS-HD | CAN protocol, Mid Motor with Ebike Battery Display Optional, for MTB and Road Mountain Bike, Great for City Daily Commuting

I bought two of these sets for use on recumbent trikes, which have the pedals out front and the drive wheel out the back. At first I was dubious about buying a Chinese motor and battery, coming from the motorcycle world, where Chinese motorbikes can be terrible. However, this system has proved it self several times over and I have come to rely upon it quite heavily, as a disabled cyclist. The unit is very easy to fit, (however, I am a qualified cycle mechanic, with a full toolset) and the tools supplied are good enough to do the job. The wiring was more difficult, due to the nature of my machine, but on a standard bicycle, fitting is even easier. I chose the heavier, bigger battery and frankly, I have barely managed to get it below 80% of its charge, even on long days. Again, as a disabled cyclist, I am not doing hundred milers anymore, but even so, I would trust this system for fifty miles or more, quite easily, even with heavy use. The system is very easy to use, but it is essential that you make sure that the unit is set to provide the power and speed limit for your country. In the UK this is 24.5KM/H. As standard, the kit came set with a max speed of 50KM/H. I chose to use the larger screen, with full utility and again, the system is simple and fairly intuitive. The screen comes with three options to choose from, but I run mine on the basic, which is very easy to use. Power delivery can be quite intense, especially if you are riding in Sport, Sport Plus or Boost mode. For this reason, it is imperative that you use the brake sensor, which cuts power to the motor while braking. Prior to fitting the correct brake lever, the pedal system would try and surge me forwards even when braking, or when moving slowly along a busy pathway. I find that the system is essential when I am tired or having a bad health day, but still want to go out. The system is activated by the pedals (although a throttle is provided, but you need to check your local laws before fitting it) and gives you the extra power. In my case, this is a 250W system. My disability means that where I used to easily produce such power, I now struggle and it is lovely to have the assistance, especially on the hills that I now struggle on. Stopping from speed does require good brakes, I run a hydraulic disk brake specific lever, that runs on mineral oil, rather than DOT, so the Bafang set up works very well with this. The down sides of a pedal assist system are small, but can be costly if ignored. I run a Shimano GRX derailleur, on an XT cassette and chain, running though 11spd bar end shifters. The pedal assist does not recognise gear shifting, so it can mash your gears quite badly if you are not careful. This has bent my derailleur hanger a couple of times and I have now fitted an electronic switch that acts like a clutch that cuts the power when I am changing gear. I have also had to change my rear hub and I am now using a Hope e-Bike hub with a steel freehub body. It was an expensive upgrade, but it was worth it after my standard ICE wheel was brutalised by poor gear shifting on my part while I got used to the system. Over all, I could not be happier with this system. It allows me to go out on family rides with my grown up kids and keep up with them, when they sprint off, at least up to 24.5KM/H! If you have the power to go faster in your legs, the system is very easy to pedal, with very little resistance. I need to be going down hill, with a strong tail wind before I can out perform the Bafang though. For a disabled cyclist, this system is both cheap and easy to fit, especially when compared to the specialist e-Bikes that house Bosch or Shimano mid drive systems. This system gave me a budget e-Trike, for less than half of the cost of a fully integrated ICE with built in Shimano pedal assist. Final tip, I use Crank Brothers Candy pedals on this system and they work very, very well with e-Assist.

Very easy to install even if you have a small knowledge about bikes great quality components. Things to do before purchase: Make sure to measure your bottom bracket for the mid drive motor, Measure your inner frame to house the battery, If opting for rear rack it can be slighly manipulated for bikes with a wider frame at your own risk and comfortable doing that. No instructions so YouTube will be your

works at it should

Installation was smooth. All the hardware was correct. Fitment is also right, performance wise. It's well more than enough very easy to take out the limiter but I have it always on as it's already enough for what it is Although if I do suggest get yourself, the biggest battery possible. Us range is In between thirty five 2 forty five kilometres

Good set, instructions on on how to assembly it could be better. Anyone that use bike more for commute than leisure should consider buying it. Few notes - bike lights wiring is not obvious. Red lights goes to front and white to back, should be other way around. Consider buying smaller sprocket. I went with 42t and sometimes it doesn't have enough torque to push it. Hydraulic brake sensors might hard to mount on some bikes. I found some 3d print files on printables that might fix the issue. Going to test it soon.

I found installment easy if you use YouTube for reference. Product seller and speed of delivery to Scotland so far impressive. Used Befang for 6 years commuting and mountain biking with a smile almost guaranteed.

This is brilliant. With not being able to drive for a year I can now cycle to the gym without exhausting myself.

Funciona todo perfectamente. Un fallo de uno de los sensores de freno lo resolvió el vendedor enviándome otro de forma inmediata. Comunicación perfecta, embalaje OK y producto perfecto. Eso si, la colocación requiere un cierto conocimiento de una bicicleta y de cómo se monta o desmonta todo.

Le moteur, et l'équipements sont de tres bonne qualité.. le montage peut être un peut difficile mais une fois monté.. votre vélo ne sera plus le même !

Va como un tiro. Convierte la bici en una Mobilette electrica.

Upon first plugging everything in there was an error 30, which is very frustrating. Turns out that just one of the little metal pins in the display connector was bent. Bending it back with tweezers worked and so far so good. Would be great to include just a bit more instructions though.
