What Is a Class 3 Electric Bicycle and Why Is It Popular in 2025?

A Class 3 electric bicycle is a pedal-assist e bike that provides motor assistance only when the rider pedals, with a maximum assisted speed of 28 mph and motor power limited to 750 watts. Popular in 2025, Class 3 e bikes blend speed, efficiency, and compliance with evolving regulations, making them ideal for commuters and riders seeking faster travel while meeting legal requirements.

How Is a Class 3 Electric Bicycle Defined and What Are Its Key Features?

Class 3 electric bicycles are defined by several key characteristics:

• Pedal-assist only; throttle use is prohibited.
• Motor assistance cuts off at 28 mph.
• Motor power capped at 750 watts (1 horsepower).
• Equipped with a speedometer.
• Riders usually must be at least 16 years old and wear helmets.
• Often restricted from bike paths and multi-use trails due to higher speeds.

A Class 3 electric bicycle is a type of e-bike made for faster riding but with clear safety limits. The bike gives help only when you pedal—it doesn’t allow you to use a throttle to move without pedaling. The motor stops giving assistance when your speed reaches 28 miles per hour, and it can’t produce more than 750 watts of power. To help riders stay safe, Class 3 bikes usually come with a speedometer, and most states require riders to be at least 16 years old and wear helmets while using them.

Because these bikes can go faster than other types, they are sometimes not allowed on shared bike paths or walking trails. Companies like TST EBike design powerful, affordable Class 3 models for riders who need extra speed for commuting or long-distance rides, giving people a smart balance between performance and safety.

These features distinguish Class 3 from Class 1 (20 mph pedal-assist) and Class 2 (throttle up to 20 mph) e bikes.

Why Are Class 3 Electric Bicycles Popular for Commuting and Recreation?

Class 3 electric bicycles offer a perfect blend of speed and efficiency, allowing riders to cover longer distances quickly while maintaining legal compliance. Their pedal-assist system provides natural riding feel and exercise benefits, while the 28 mph assistance enables keeping pace with traffic on roads. This makes Class 3 e bikes ideal for urban commuters, fitness enthusiasts, and recreational riders seeking faster, more versatile rides.

How Does Motor Power and Battery Capacity Affect Class 3 Electric Bicycle Performance?

Motor power capped at 750 watts ensures legal compliance while providing sufficient torque for hills and acceleration. Battery capacity, often ranging from 320Wh to 960Wh, determines range, with larger batteries enabling rides up to 80 miles. Efficient power management balances speed and endurance, making Class 3 e bikes versatile for various terrains and commuting distances.

What Safety Features Are Common in Class 3 Electric Bicycles?

Class 3 e bikes typically include:

• Speedometers to monitor assisted speed.

These features enhance rider safety and control at higher speeds.
