Zero S Electric Motorcycles

The bikes all feature direct-drive by chain, and are recharged from either 110 or 220-volt household supplies. The street machines have larger battery packs than the off-road equivalents, and weigh a little more. But none of them is heavy. Zero claims 277 pounds for the dualsport DS model and 161 pounds for the X trailbike.Designed by aero-engineer and accomplished mountain-bike designer Neale
