Confident braking is provided by the Bosch anti-lock braking system (ABS). As a result of extensive testing, the system improves deceleration when using the brakes firmly. The levers that control the braking system may be modified for better ergonomics. The rider may activate or deactivate ABS at any time.

Rocket to speeds over 100 mph without a hitch thanks to a system that converts energy into propulsion without a trace. The Zero S is a direct-drive vehicle.

Standard Charge Port

It is sophisticated yet understated. Specific charging ports are available on most devices, and the onboard charger may be plugged into any ordinary home outlet thanks to a lightweight wire. There is no need for extra charging equipment.
