It is an incredibly light and nimble chassis that we all know and love that we have kept the feel and handling of by engineering our 5052 & 6061 ladder frame mounts to make sure to retain proper frame rigidity/flex without adding any additional weight.

Due to some clever engineering, the E&C team was able to achieve a true riding weight of 242 lbs.! But most importantly keeping the weight distribution a spectacular 47% Front and 53% rear. This makes for the perfect ride feel and bike balance that allows for untouchable general performance but most specifically Enduro performance in the E-Moto World.
