We provide our customers with the best selection of electric motors and battery systems to fit their lifestyle and needs. There was great potential in the 8fun mid drive system, and we customized it to our specifications to be the best mid drive solution available! We tested these motors in real world climbs over 3,000 ft., and they perform beautifully.
There is no hill this motor cannot conquer, so if you want an integrated conversion kit 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 Motor from all other retailers is our custom 26A 9 FET controller custom made exclusively for us from Bafang. Most retailers will have anywhere from 21A-25A controllers depending on where you source it.
Our kits come standard with a custom 6061 Aluminum Adapter that allows for our 32-38T sprockets vs. the standard 46 or 48T. Our narrow chain ring provides more consistent chain retention, and allows the motor to gear down for higher torque and efficiency.
Finally, our custom programming capability gives us full access to every parameter these motors have to offer. We provide custom profiles on our 1200W+ systems in PAS 1, 2, 3, and 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 as benign on the chains and sprockets as possible. In this setting you are less likely to damage gears, because of the programed smooth 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.
All 36V motors will have the same "500W" stamp on the bottom as other 8Fun Mid Drive Motors. All 48V+ motors will have the "750W" stamp on the bottom. We feel these numbers are misleading, and by no means is any 750W BBS02 fully street legal, as even the least powerful versions we have tested from other vendors still put out over 1000W. It is a game that the manufacturer plays to try to be "legal" in certain countries when in fact they are not!
This is why we always provide actual system outputs both electrically and mechanically with output to the rear tire where it matters! It is misleading to think our 1400W kit is almost twice as powerful as another 750W BBS02, because it is not. They are anywhere from 50-250W higher on average for the same battery for "750W" stamped motors. Compared to a true 25A output controller (stamped 48V x 25A), we see on average about 50-60W higher power output. In rare cases, we have seen over spec 25A controllers from other vendors that have even slightly exceeded our 26A controllers.
