DSCN0165 004

ZEV now is shipping the new T8500 and 8500 LR. These are replacing the T7100 and 7100LR in the ZEV line up. After a recent controller and motor tune up ZEV has been able to give the same bikes some added punch. Peak power at full charge jumped to 10,000 watts. The price of the bikes has not changed, leaving retail pricing at $8895 for the T8500 and $8990 for the 8500 LR. 

With a curb weight of only 365 lbs, and 103 lb-ft of torque, the bike is quite quick. For more information, visit
