Suitable for bicycles with a gear speed of 9 or less. There is a risk that the chain will come off if the bike exceeds 9 speed. If you're not sure if the BBS02B bike motor kit fits, please send me a picture of the bottom bracket. **Choose BB68mm for 68-73mm and BB100mm for 90-100mm. [RIDING MODE] BAFANG BBS02B 48V 750W The maximum speed of the mid motor can reach 50KMH (for 27.5 inch e-bikes). A thumb throttle is included, so you can turn it to drive. You can also ride your bike in pedal assist mode without using the throttle. [Display] The display is different from the interface, size, buttons, USB ports, etc. You can learn from our product images and decide which e-bike display you prefer. MPH/KMH can be set as needed. [Chainring] You need to replace your existing chainring with a BAFANG chainring. There is a 36T 44T 46T 48T 52T chainring for the BAFANG mid drive kit. When converting a bike with a mid-mounted ebike conversion kit, the size of the chainring doesn't have much effect on ride speed because the motor supports super power and the speed can be set at each PAS level. The easiest way is to choose the same tooth chainring as the original one. ** The 36T chainring has no chain guard.
