250W brush motor

Before order (important):

1). This kit is for the bike that using the V brake on the rear wheel.

If your bike uses disc brake or coaster brake, this kit does not compatible with that bike, please choose other kits.

2). The motor bracket maybe does not fit your bike frame, this you need to modify the bracket by yourself, please confirm this.

If you do not know how to modify, please send me your bike picture, so I can give you suggestion.

3). This kit just for people riding bike easier, it is not fast (26-inch bike can run about 20km/h), you'd better pedal with the motor power, this can ride longer, please understand.

4). The difference between 24V and 36V is the working current, if you want to ride longer, I recommend 36V kit.

5). This kit does not include battery, you need to buy the battery separately, the lead acid battery and the lithium battery are all ok, and the battery capacity I recommend 24V 15Ah or 36V 12Ah.

6). This controller comes with 1 fuse wire and 3 fuses, if you burn 1 fuse, you'd better note what makes it burnt and avoid this happen again, or please feel free to contact me for help.

7). This item has 2 throttle types for choice, if you want the twist type, please choose the "key throttle" option, and if you want the thumb type, please choose the "thumb throttle" option, thank you.
