Just getting my feet wet with ebikes. Bought an entry level 500 watt 48V geared rear hub bafang kit on ebay. So far haven't installed the PAS sensor yet, just bump the PAS setting on the display up to level 5 and use the throttle. Happy with the thumb throttle. Performance is pretty good for a fairly inexpensive kit, but I notice the power cuts out at 25mph. Installed on a bacchetta recumbent, super fast aerodynamic bike, easily goes 30 mph on a mild decent with pedaling, but the motor stops helping at 25 . Motor controller has an amp limiter at 18 amps. I know the 25mph cut-out is not due to the amperage limiter, because the electric assist stops helping even when i'm descending at 25 and would only need minimal power consumption from the motor to bump me up to 30. Must be some sort of speed limiting setting. Can this be changed? Hacked? Reprogrammed?
