RadWagon 4

The Ultimate Cargo Hauler Electric Bike

It’s the strongest and most versatile version of the RadWagon yet, featuring smaller, innovative new tires developed by our in-house team of expert engineers to achieve a lower center of gravity. Its patent-pending new frame design ensures multiple points of adjustability, including a telescopic seat post and easily maneuverable handlebars.

Let Us Do the Heavy Lifting

This is a next-level hauler designed for those who are loading up to go somewhere, whether that’s taking the kids on a trip across town or a weekend visit to the hardware store or farmer’s market. With a standover height 2.4 inches lower than its predecessor and a 750W geared hub motor, the RadWagon 4 is in it for the long haul.

Technical Specifications

This is what makes the RadWagon 4 the best in its class.

New With RadWagon 4

Smaller, Wider Tires

All-new 22" x 3" tires designed in-house by Rad Power Bikes' team of product engineers and manufactured by VEE Tire Co. provide a lower center of gravity. Features a custom tread pattern that provides a smooth ride over uneven surfaces, withstands bumps, and handles the elements with ease.

New With RadWagon 4

750W Geared Hub Motor 

Provides twice the torque as the direct drive hub motor found on previous RadWagon models, making uphill hauling and quickly getting up to speed from a stop easier.

New With RadWagon 4

Telescoping Seatpost

Equipped with a telescoping seatpost with a 375 mm maximum length that's capable of accommodating riders between 5'1"-6'4".

New With RadWagon 4

Adjustable Handlebars 

An adjustable handlebar stem allows riders to customize the reach, height, and handlebar angle (up to 80 degrees) with zero tools.

7-Speed, 11-34 Tooth Freewheel

A wide range of gearing at your disposal means more torque for steep climbs and maintained pedal authority at top speed.

Reflective Tire Sidewall Striping

Extremely durable and with a larger total reflective surface and better visibility than traditional spoke-mounted reflectors.

Integrated Brake Light

Powered using the main battery pack and featuring brake light functionality that activates any time the brakes are applied.

Integrated Rear Rack

Attach panniers, platforms, or baskets and let the bike carry your cargo -- up to 120 pounds. Or mount a Yepp Maxi child seat, Caboose, or Deckhand to bring up to two kids along for the ride.

Twist Grip Throttle

750W of power on-demand allows you to only use the throttle when you don't want to pedal. Ideal for starting from a stop when your bike's loaded with cargo.

180 mm Mechanical Disc Brakes

Tektro Aries brakes provide you with strong stopping power, even in loose or wet terrain.
