1). This kit is for the bike that uses a single-speed freewheel.
If your bike has some speed gears or the gear is fixed, this kit is not compatible with that bike, please choose other kits.

If you are not sure about your bike type, please send me your bike picture, so I can recommend the correct kit.

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

If you do not know how to mount it, please send me your bike picture, so I can give you suggestions.

———-

3). This kit is for people riding the bike easily, it is not fast (on a 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 the 36V kit.

———-

5). This kit does not include a 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 and 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.
