Just installed my 36v lifePO4 battery and went for a test ride. All I can say is
HOLY CR@P!
Top speed on flat surface 27.6MPH (could gone faster if I bent over to be more aerodynamic but that is a little scary go this fast.)
Top speed up mild hill 24.3MPH
The sound of the motor at these speeds was AWESOME!
Smile on my face endless!
27MPH was amazling fast on a bicycle. I thought I wanted to build a bike with a X5 or BMC motor and add enough juice to do 40+MPH but I think 27MPH is plenty fast.
Gotta get some sleep but will post how to video and video of the 36v bike in action tomorrow!
