Hi-Power Cycles launched a 10 Kw AWD EV mountain bike at the HPC Tornado in March, 2012.
AWD on demand, steep hill climbing ability and fast acceleration. The 150A BMS system controlled Nano Lithium Chemistry battery is the longest lasting and lowest impedance on any electric bike with up to 1200 Recharge Cycles!
Production is expected 'soon'.
