I use modified SLA charger 150W. It used to be for 66V 12Ah or 5x12V SLA batteries. But I rised a little bit of voltage from 66V to 73.5V. And it charge to full ~73V which is for 20x3.6V.
Top Speed38 MPH (61 KPH)
24" rear wheel. On a the 1% slope hill, going downhill reached 41mph. Going pretty steep hill like 6% or even more, there are no problems to reach ~32mph without pedaling even from a dead start on the hill.
AccelerationPretty good. You can wheelie from start or going 5mph. But in short burst only cause the motor and controller heat up realy fast.
