From my own experience and talking to others, your condition is normal albeit highly undesirable. The throttle has a large dead band at start and then a very aggressive 0-100% ramp in 1/8 of a turn. Some people like this on-off type of response. From what I understand, the controller on the 36V and the 48V bikes does not reduce speed unless completely cutoff. This results in a very uncomfortable ride. I replaced the throttle with a Magura and the controller with a Kelly KDS48200E which has an absolute maximum voltage of 60V. People considering using 16S LiPo should use the KDS72200E. These fit in the same spot as the OSET controller, the RS232 connector facing forward and flush with the bottom of the adjustment opening. This combination allow one to adjust the dead band as well as the effective throttle response with a maximum rotation of 70 degrees and a very smooth and controllable bike with amazing power when one actually wants it.
