The Family Car Replacement
The Rad Power – RadWagon 4 Electric Cargo Bike is designed to replace your minivan or second car . This fourth-generation long-tail cargo hauler combines thoughtful engineering with family-friendly features, making it one of the most accessible and affordable cargo ebikes on the market.
Powerful 750W Geared Hub Motor
The RadWagon 4 is equipped with a 750W geared hub motor producing 80Nm of torque . The Rad Power – RadWagon 4 Electric Cargo Bike accelerates quickly up to 20 mph (Class 2) and maintains speed confidently on hills, even when fully loaded.
Up to 45-Mile Range
The 48V 14Ah (672Wh) Safe Shield lithium-ion battery delivers an estimated 25-45 miles of range depending on terrain and load . In all-throttle range testing with 1,450 feet of climbing, the bike still managed 26.38 miles — representing the absolute minimum you can expect.
The Rad Power – RadWagon 4 Electric Cargo Bike battery locks into the downtube and can be charged on or off the bike in 6-8 hours.
350-Lb Total Payload Capacity
Built to haul, the RadWagon 4 supports a total payload of 350 lbs, including 120 lbs on the rear rack . The elongated frame and lower center of gravity provide stable, reliable rides even when you’re taking full advantage of the weight capacity.
7-Speed Shimano Drivetrain
A Shimano Tourney 7-speed drivetrain with an 11-34T freewheel gives you the right gear for any hill or load . The Rad Power – RadWagon 4 Electric Cargo Bike adapts to your terrain, making steep climbs manageable even with two kids on the back.
Custom 22″ x 3″ Tires
Rad’s in-house engineering team designed the custom 22″ x 3″ tires specifically for cargo hauling . The smaller, wider wheels lower the center of gravity, improving stability when loaded. The plus-size width helps soak up road bumps while the smaller diameter delivers more torque to the ground.
Low-Step Frame for All Riders
The redesigned low-step frame features a 23.6-inch standover height, making mounting and dismounting effortless even when fully loaded . The Rad Power – RadWagon 4 Electric Cargo Bike accommodates riders from 5’1″ to 6’4″ (155-193 cm) thanks to a telescoping seatpost and adjustable stem.
Mechanical Disc Brakes
Tektro Aries mechanical disc brakes with 180mm rotors provide reliable stopping power in all weather conditions . The brakes are tested for all-weather stopping ability, giving you confidence when carrying precious cargo.
5 Pedal-Assist Levels Plus Half-Twist Throttle
Choose from 5 cadence-based pedal-assist levels plus a half-twist throttle . The motor responds to pedaling motion rather than rider effort, providing consistent power that kicks in within half a pedal stroke. Level 5 offers the punchiest acceleration for conquering hills with heavy cargo.
LCD Display with USB Charging
The centered 2.25-inch LCD display tracks speed, distance, battery levels (via five bars), and real-time motor wattage . Six intuitive data fields and an integrated 1A USB charging port for your devices keep all your essential ride metrics visible at a glance.
Integrated Lighting for Safety
Reflective striping is incorporated on tire sidewalls, plus an LED headlight and integrated taillight with brake light indicator keep you visible day and night . The Rad Power – RadWagon 4 Electric Cargo Bike ensures you’re seen by other road users.
Full Fenders and Heavy-Duty Kickstand
Full-coverage fenders front and rear keep you dry on wet roads . A heavy-duty, center-mount dual-leg kickstand near the bottom bracket provides stability for loading cargo or passengers — you can push forward to ride without manually raising the stand.
The Custom 22-Inch Ecosystem
The proprietary 22″ x 3″ tire size was a deliberate design choice to lower the center of gravity . While this means you can’t run standard tires, Rad Power Bikes maintains a supply of replacement tires and tubes, and aftermarket options are now available.

- Passenger seat and running boards for kids

Designed for Two Parents
The adjustable handlebar and telescoping seatpost let you quickly achieve a custom fit for riders of different heights without tools . The Rad Power – RadWagon 4 Electric Cargo Bike works for both parents, so whoever is taking the kids can ride comfortably.
Assembly and Delivery
The bike ships with 85% assembly complete . You’ll install the front wheel, handlebars, and fenders — about an hour with included tools. At 76.2 lbs, it’s a hefty package, so a two-person assembly is recommended.
