At Hi Power Cycles, we constantly innovate to provide our customers with the best selection of electric systems to fit their lifestlye and needs. We saw great potential in the 8fun mid drive system and went about trying to make this the best mid drive solution available! We have tested these on 3,000 + foot elevation climbs and they perform beautifully. If you have hills to conquer or want a nice integrated conversion that you can control the torque and speed then this is the system for you! The main differences of our system vs a standard BBS02 750W lies in our custom programming and full power controllers.  Most retaillers will have anywhere from 21A-25A depending on where you source it. Our kits come standard with a custom 6061 Aluminum Adapter that allows for our included 32-38T sprocket vs the standard 46 or 48T.  Compared to stock, the narrow wide chainring provides more consistant chain retention and allows the motor to be geared down for higher torque and efficiency. Most important is our programming.  We have full access to every parameter of these motors and provide custom profiles on our 1200W+ systems in PAS 1, 2, 3 to allow them to be EU legal in PAS1, 500W legal in PAS 2 and US legal with 750W maximum output in PAS 3. We also optimize on throttle and Pedal Assist response to be more benign on chains and sprockets so you are less likely to damage gears with a smoother engagement.  We offer 7 levels of pedal assist and a Throttle only mode as well.  Full throttle over-ride is available in all PAS modes except 0. 

These units include the follwing: 1) custom programming (these offer up to 9 speed of pedal assist, a throttle only mode, and ability to use the full power throttle in any pedal assist mode)  2) Maximized power output with high end internal controller 3) Extended Speed Sensor Cable 4) Custom Anodized Aluminum Spider with high quality single speed anodized crank + custom mounting hardware. We have added approximately 20% more torque than the stock system allowing the system to run cooler and more efficient with minimized chain issues.

We have tested these units with our dynojet dynamometer in our shop and the results were very positive! Please Look at the last picture for actual dyno of this system on one of our bikes.
