⚡ Throttle

The Engwe ENGWE P20’s throttle-yes designation means that in addition to five levels of pedal-assist, riders can engage the rear-hub motor on its own. With a simple twist or push of the throttle, the P20 will deliver its full power output—up to the legal limit of roughly 20 mph (32 km/h)—without any pedaling input. That immediate surge can be especially handy for getting rolling from a stoplight or for trimming minutes off each trip when you don’t want to stand on the pedals.

By contrast, many budget or commuter-style e-bikes either skip the throttle entirely or limit it to just a 3–5 mph walk-assist mode. The P20’s full-speed throttle puts it in a more versatile class: you’re not tied to the crank, and you can maintain the same top speed whether you’re pedaling or not. In practice, this means on a steady flat stretch many riders report holding 18–20 mph under throttle alone, matching what they’d get in the top pedal-assist level but without the legwork.

This feature matters most for riders who face recurrent stop-and-go traffic, those with joint or mobility concerns, or anyone who appreciates an instant boost up short hills. Commuters juggling tight schedules may find the throttle shave seconds off each signal, while weekend explorers can deploy it for a quick recovery on rolling terrain. In all cases, having a full-function throttle gives the P20 added flexibility over models that rely solely on pedal power.
