The Premium Utility Cargo Ebike
The Rad Power – RadRunner 3 Plus Electric Utility Bike is the flagship model of Rad’s cargo bike lineup. Engineered for riders who demand more, this premium utility ebike combines hydraulic disc brakes, a 7-speed drivetrain, front suspension, and genuine passenger capability.
Powerful 750W Motor with 70Nm Torque
This model is powered by a 750W brushless geared hub motor producing 70Nm of torque. You can summit local climbs 10% faster than previous RadRunner models, making daily commutes and cargo hauling effortless.
Up to 45-Mile Range
The semi-integrated 48V 14Ah (672Wh) Safe Shield battery delivers an estimated 25-45+ miles per charge. It features a sleek, streamlined design that is fully certified to UL 2271 safety standards.
Range Extender Compatible (100+ Miles)
The RadRunner 3 Plus is the first ebike in Rad’s lineup that can accommodate a dual-battery Range Extender. Currently in development, this accessory slides under the rear rack to more than double your range — up to 100+ miles per charge.
7-Speed Shimano Drivetrain
Unlike the single-speed RadRunner 2, the 3 Plus features a 7-speed Shimano drivetrain with an 11-34T freewheel. You get the right gear for any hill or load, making this bike vastly more versatile than its budget-focused sibling.
Hydraulic Disc Brakes for Superior Stopping
Tektro hydraulic disc brakes with 180mm rotors bring the bike to a quick, controlled stop. The levers are adjustable, accommodating both smaller and larger hands, and providing fade-free stopping power even when fully loaded.
60mm Front Suspension Fork
The RST spring fork offers 60mm of travel, smoothing out bumps, potholes, and rough city streets. Both rider and passenger stay comfortable on any terrain.
350-Lb Total Payload Capacity
This bike supports an impressive 350 lb total payload capacity, including 120 lbs on the integrated rear rack. It hauls groceries, gear, and a full-sized passenger without breaking a sweat.
Passenger-Ready Design
The RadRunner 3 Plus is built to carry a co-pilot. The optional Passenger Package includes a plush seat, retractable footpegs, and a protective wheel skirt, bringing you and your companion within perfect conversation distance.
Ergonomic Low-Step Frame
The redesigned low-step aluminum frame makes mounting and dismounting effortless. It accommodates riders from 4’11” to 6’2″ (150-188 cm) with a weight capacity of 350 lbs.
20″ x 3.3″ All-Terrain Tires
The Kenda K-Rad tires measure 20″ x 3.3″ with K-Shield puncture protection and reflective sidewalls. This bike tackles pavement, gravel, dirt trails, and wet roads with equal confidence.
5 Pedal-Assist Levels Plus Throttle
Choose from 5 pedal-assist levels plus a half-twist throttle. The pedal cadence sensor delivers consistent power based on your selected level, letting you pedal with assistance or cruise without pedaling.
LCD Display with Auto-On Lights
The LCD display shows speed, battery level, assist mode, and trip data. Integrated front and rear LED lights feature an auto-on function — they activate when your surroundings get dim. The rear light includes a brake light function.
Full-Coverage Fenders and Center Kickstand
Full-coverage fenders front and rear keep you and your passenger dry on wet roads. A sturdy center-mount kickstand keeps the bike upright when loading cargo or passengers.
IPX6 Weather Protection
This model carries an IPX6 water-resistance rating, meaning it can withstand high-pressure water and heavy rain. Ride confidently in all seasons.
