Welcome to the G-force family! We are so glad you chose G-FORCE ZM and let us start with some basic operations.

Operating Modes

Using this mode, it works like a normal mountain bike with a fundamental mechanical function of shifting gears on the right hand. You can shift from 0-7 to swap the chain from one cog to another.

Pedal Assist Mode

Using PAS mode, you will have to turn on the bike first, but do not need to use the throttle. The electrical assistance will kick in when you pedal. It works like a constant tailwind at your back and gives you a little boost on your pedals. It gives pedal assistance automatically by the participation of its concomitant pedal sensor. The harder you pedal, the more assistance you will gain.

Throttle-Only Mode

Using the throttle-powered mode, you do not need to pedal, but turn on the bike and press the Half twist throttle to get your bike rolling forward. Simply press "UP"(+) or "DOWN"(-) to change the speed gears, the 3rd gear is the pre-determined top speed.
