250W brush motor

For order (important):

1). This kit is for bicycles that use V-brakes on the rear wheel.

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

If you are unsure of your bike type, please send me a photo of your bike so I can recommend the right kit for you.

2). The motor mount may not fit your bike frame; you'll need to adjust the mount yourself and confirm this.

If you don't know how to adjust it, send me a picture of your bike so I can give you a suggestion.

3). This kit is only for people who prefer more relaxed cycling. It's not fast (a 26-inch bike can reach about 20 km/h). It's better to pedal with the motor power, as this can take longer to ride. Please understand.

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

5). This kit does not include a battery; you must purchase one separately. Lead-acid and lithium batteries are both acceptable, and I recommend a 24V 15Ah or 36V 12Ah battery capacity.

6). This controller comes with one fuse wire and three fuses. If you blow one fuse, you'd better identify what caused it and prevent it from happening again, or feel free to contact me for assistance.

7). This item has two types of throttle for your 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.

FALSE description/POOR business practice
These needle cartridges do NOT fit the Dr.pen Ultima M7-W as it states in description. Beware when buying because I noticed when doing the return that they keep $5.00 of your purchase price when you return. I NEVER would have ordered from here had I known that before my purchase! This is pretty ridiculous and VERY POOR business practice if you ask me , especially when their own description states that they will fit the pen I have. BOOOO!
