My build:
MAC 10T @ 48v, 9 fet 30A controller, CA-DP.
27mph top speed, pulls like a train up most hills.
Ten reasons why you should buy a MAC 500w kit from Cellman.
Not in any particular order:
1. Excellent customer service.
2. Solid wheel build with true rim (really helps if using on rim brake bike)
3. Infineon controller direct CA compatible (you can learn so much about your bike set-up using a CA)
4. Paul (Cellman) is a genuinly nice guy and will do his utmost to advise and help.
5. Kit fits a standard bike with no problems and has been obviously very well designed.
6. 3-speed switch is very useful (nice, progressive throttle control at lower speeds)
7. Easily replaceable parts.
8. Programmable controller.
9. Option of upgraded phase wires and temp sensor if required.
10. Excellent customer service
