## Features

- Motor Brand:UNITE
- 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. If you can not sure your bike type, please send me your bike picture, so I can recommend you the correct kit.
- 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.

## Questions & Answers

**Q: will this motor keep up with traffic on the turnpike ?    :)**
A: I know your question is just a lark, but if you were to gear things right, you could go way faster than you would think. These things are to assist your pedaling, not to replace you pedaling. If you want to go fast, go get a motorcycle, and join the rest of the gasoline bunch. If you do manage to get on turnpike, with a bike, take a video and put it on YouTube. That would be interesting to watch.

**Q: Will this work with the dynacraft alpine eagle 700c 45cm aluminum frame hybrid bike?**
A: You can put this on just about anything that rolls. How easy or hard, depends on how you mount the motor. I imagine the price of an aluminum frame bike, would tend to make you NOT WANT to drill many holes though.

**Q: I purchased this 36V 250w left chain drive derailleur kit ,,, i received right side clockwise motor. now what ? help.**
A: Yes, the motor rotates clockwise, so when you mount it on the bike left side, it can drive the wheel go forward.
The right drive kit motor rotates anti-clockwise .

**Q: Is there anyone who can provide a real review of just using the parts without mods; what battery to purchase?**
A: I've installed 7 bike kits and all bikes are different. This is a universal kit therefore some modification are required. The only kits I've done that don't require modification are the ones that change the entire wheel.

Concerning the battery, go with their recommendation or larger. I've never had a problem there, but all of my installs use the motor to assist their pedaling or going up hills.
