Pedal assist and throttle mode are common assist systems in e-bikes, and they can provide riding assistance to help people have a better riding experience. While both bring a great deal to the ride and have some similarities, there are also many differences between the two.
How pedal assistance works
Pedal-assist e-bikes use sensors to detect when the rider is pedaling and provide the appropriate power to help the rider ride, so this mode is only activated when the rider is pedaling the pedals. Typically, pedal assist has a number of different modes that provide different levels of power, but these rely on the rider pedaling. Lower levels provide a moderate power boost, while higher levels help with tough climbs and can help you complete an easy riding experience on challenging terrain.
How the throttle system works
Unlike pedal assist, the throttle on an e-bike doesn't require any pedaling, just twisting the vehicle's turnbuckle. It provides an instant power boost compared to pedal assist. When the throttle is turned, the motor will continue to supply power until the vehicle reaches its maximum speed. You do not have to pedal in the meantime.
Key differences between the two
The main difference is that pedal assist is only activated when pedaling, whereas the throttle provides power instantly. The pedal assist adjusts the motor assist based on how hard the rider is pedaling. The throttle provides constant power, whether the rider is pedaling or not. In addition, frequent use of the throttle will drain the battery more quickly. In terms of speed, the rider can easily change speed by applying different forces, and throttle mode must be closed to achieve deceleration control.
In summary, pedal assist is for riders who still want a good workout from pedaling but want a moderate boost in power over distance or hills. Throttle benefits riders who want to minimize pedaling effort on long commutes or challenging terrain.
