Charge Comfort and City models have five assist levels, plus a throttle that enables you to ride without pedaling.
Assist Level 1 provides the least assist (and most range), while Assist Level 5 provides the most assist.
The Charge XC model has three assist levels and no throttle; you must be pedaling to activate the assist.
All Charge Bikes have a Walk Mode which propels the bike forward at a walking pace to assist you with moving your bike without the need to push its full weight.
