2025 Rad Power Bikes RadWagon™ 4 Electric Cargo Bike

Holds the kiddos. Plus groceries.

This next-level hauler is perfect for taking the kids across town or loading up at the hardware store. The electric cargo bike's elongated frame and lower center of gravity provide stable, reliable rides, even when you’re taking full advantage of the 350 lb. payload capacity. Take a passenger (or two!) for a spin. Our family-friendly accessories get the whole gang outside.

Best Electric Cargo Bike

RadWagon 4 is the best electric cargo bike we've tested.

We go the extra mile.

All Rad ebikes are either UL Certified or tested by ACT to comply with UL 2849.

This means our bikes and electric systems have undergone rigorous testing to meet safety standards set by UL, a respected third-party organization.

Although U.S. guidelines don’t currently require ebikes to meet UL Certification, we go the extra mile to ensure our riders feel safe in the saddle.

See and be seen

Safety is paramount to Rad engineers. Reflective striping is incorporated on tire sidewalls, plus the LED headlight and an integrated taillight with brake-light indicator keep you visible to all.

Precision in practice.

Every ebike, without exception, receives a thorough 50-point inspection. How in-depth is it? Even the screws are double-checked.

Brake confidently in any weather conditions.

Ride rain or shine. Every ebike comes with brakes tested for all-weather stopping ability.

Features may include:

Integrated rear rack
  • Attach bags, baskets, passenger seats or simply strap on bulky items - the extended size and integrated rack make hauling a cinch.
Geared hub motor
  • Climb hills and zip across intersections powered by our Rad-engineered 750W motor, designed in-house to help you go steeper at lower speeds.
Telescoping seatpost
  • Equipped with a telescoping seatpost with a 375 mm maximum length that's capable of accommodating riders between 5'1" - 6'4".
Custom tires
  • The 22" x 3" tires, designed in-house by Rad engineers, feature a custom tread pattern for smoother riding on uneven surfaces, and an overall size that provides a lower center of gravity.
