Throttle vs pedal assist: how each e-bike mode works and who it suits

How pedal assist works

Pedal assist, often shortened to PAS, adds motor power while the pedals turn. A sensor near the cranks tells the controller you are pedaling, and the motor adds help at the level you pick on the display. Stop pedaling and the help fades.

Assist levels set how much help you get. The lowest level feels like a light tailwind and stretches the battery furthest. The highest feels like the bike is carrying you. The number of levels varies: the Segway Xafari and Segway Xyber list 12 levels of pedal assist, the Gyroor EB262 lists 3 assist levels, and the Gyroor EB263 lists a color LCD with 3 ride modes.

How the help feels depends on the sensor. A cadence sensor gives a steady push once the pedals turn, and a torque sensor matches how hard you press. We explain both in torque sensor vs cadence sensor.

How a throttle works

A throttle sends power to the motor without any pedaling. It is usually a thumb lever by the grip, like the thumb throttle WEPED lists on the WEPED F1, or a twist grip. Press a little for a gentle start, more for full power.

Many electric bikes let you choose how to ride from the display:

• Hiboy lists three riding modes on the EX9, P6, EX6 and EX6F: bike, power assisted and pure electric. Pure electric is the throttle mode.
• The NANROBOT Q3 lists electric, pedal assist and manual modes.
• The Gyroor C33 lists electric, pedal assist and pedal only modes.

The brake levers cut the motor on most electric bikes, so pulling a brake stops the throttle as well as the pedal assist. The Hiboy C1, for example, lists front and rear disc brakes with motor cut-off.

What the classes allow

In states that use the three e-bike classes, the throttle is what sets class 2 apart. Class 1 helps only while you pedal, up to 20 mph. Class 2 adds a throttle that can move the bike on its own, also up to 20 mph. Class 3 helps only while you pedal, up to 28 mph. Our guide to e-bike classes explained covers the limits and where each class may ride.

That is why many models list two top speeds. The motor stops helping at 20 mph on the throttle, and goes higher only when you pedal:

• Hiboy P6: 20 mph in throttle mode, and up to 28 mph with pedal assist as a class 3 bike.
• The Dodge Electric Bicycle: 20 mph on the throttle and 28 mph with pedal assist.
• Hiboy EX6 and Hiboy EX6F: 20 mph on the throttle and up to 25 mph with pedal assist.
• Hiboy EX11: class 2 at 20 mph by default, switchable to 28 mph as class 3, pedal assist only, where permitted.
• Hiboy C1: 20 mph on the throttle and up to 20 mph with pedal assist.

How each mode affects range

On the throttle, the battery does all the work, so the miles drop. With pedal assist, your legs share the load. Makers that list both figures show the gap:

• Hiboy EX11: up to 100 miles with pedal assist and up to 53 miles on the throttle, both with a 165 lb rider.
• Hiboy P6: 50 to 62 miles power assisted and 25 to 31 miles on electric power alone, with a 143 lb rider.
• NANROBOT Q5: up to 62 miles with pedal assist and 25 to 31 miles on the throttle.
• NANROBOT N1 20-Inch: up to 40 miles with pedal assist and about 15.5 miles on the throttle.
• Hiboy C1: 26.2 miles power assisted and 21.7 miles on electric power alone.

Most of these pairs land near half. The C1 is the exception, with a small gap. Riding mostly on the throttle? Compare the throttle figure where the maker lists one, or halve the headline number. Our guide to electric bike range covers what else drains a battery, and our sibling guide to long range electric bikes lists the models with the biggest batteries.

Who each one suits

A throttle suits you if:

• You ride in stop and go traffic and want an easy pull away from every light.
• You start on hills, or carry shopping, a child seat or cargo.
• You want to rest your legs, or arrive at work without breaking a sweat.
• You are getting back on a bike after a long break. Our guide to choosing an electric bike for seniors covers easy starts and mounting.

Pedal assist suits you if:

• You want exercise, with the motor taking the edge off.
• You want the most miles from each charge.
• You ride paths or trails that allow class 1 only.
• You want a ride that feels like a regular bicycle, especially with a torque sensor.

Most riders use both. A common pattern is the throttle for the first few pedal strokes from a stop, then pedal assist in a low level for the cruise.

More of our e-bikes with both modes

• NAVEE Wolf X: throttle and pedal assist, class 1, 2 and 3 switching, 9 gears and 85 Nm of torque on a step-through frame.
• Hiboy EX9: bike, power assisted and pure electric modes, a dual-sided torque sensor, and 20 mph by default, adjustable up to 28 mph with pedal assist where local rules allow.
• Segway Xafari: 12 levels of pedal assist, class 2 at 20 mph or class 3 at 28 mph where allowed.
• NANROBOT Q5 and NANROBOT N1 20-Inch: separate throttle and pedal assist range figures, a removable 48V battery and Shimano gears on each.
• WEPED F1: a thumb throttle with a separate pedal assist control, about 75 miles on the throttle and about 124 miles with pedal assist. It lists a top speed of about 50 mph, well past the class limits. Our sibling guide to the electric moped explains how rides like this are treated.

Not every listing names its modes. If a throttle matters to you, ask us before you order.

Riding with a throttle and pedal assist

• Start in the lowest assist level, and try the throttle gently in an empty lot before you ride in traffic.
• Ease onto the throttle. Full throttle from a stop can lift the front or spin the rear wheel on loose ground.
• Drop the assist level in crowds and on narrow paths, where fine control matters more than speed.
• Switch the class down before you join a path that allows only class 1 or class 2, if your bike has a class setting.
