Evolving in a good way from it’s siblings, the RadRunner 2 and RadRunner Plus, this bike retained some of the same key features of past versions, like a step-thru frame, 750-watt motor, 20” x 3.3” tires, BMX handlebar for upright riding posture, and the “I can do it,” spirit.
Adopting the same Shimano Altus 7-speed from the RadRunner Plus gives adequate gearing ranges while also being easy to shift and easy to pedal at any speed. It also provides a wider power band for the motor. The 11-34T cassette is a good size for hill climbing and for largely eliminating the feel of ghost pedaling at all but the top motor-assisted speed of 20 mph (where it’s only barely noticeable).
Unique to this model is the newly designed frame, which added tubing between the bottom tube, on through to the seat tube, and ending at the seat stay. This makes the RadRunner 3 Plus handle better, while also making it much stronger for passengers and cargo. The RadRunner 3 Plus now accommodates payloads up to 350lbs.
Rad also refined the suspension fork, shortening it from 80mm to 60mm travel to make pedaling easier when going uphill and for carrying goodies on the rear rack. Shortening the fork from 80mm to 60mm may seem counterintuitive, but this bike is not designed for serious off-roading so it doesn’t need longer travel for absorbing big bumps. By shortening the travel on the forks, this provides a more controllable ride, especially for heavier riders.
The shorter forks still feel great for smoothing out roads as they take the edge off, and since the geometry keeps the rider fairly upright you don’t lean into your palms too much anyway meaning your hands and wrists don’t tire easily. You can also lockout the fork should you wish.
Switching from the narrower and taller handlebar (680mm wide, 10” high) to a wider and shorter handlebar (710mm wide and 8.7” high), gives greater control while also providing a slightly lower profile that makes turning better. The reach runs a tad short, but you can adjust the front-to-back tilt of the handlebar to help dial it in to you.
Rad made a great choice upgrading the brakes from mechanical disc to hydraulic disc brakes. Some noticeable advantages are greater stopping power (the details are coming up in our brake test), better brakes are safer for heavier payloads, and the improved performance when feathering the brake on turns and temporary slowdowns, like dodging pedestrians, dogs and slower bikes.
While not exclusive to the RadRunner 3 Plus, Rad Power Bikes also debuted an optional 25 lbs Rad Trailer, with 16-inch wheels, that’s suitable for hauling heavier loads (up to 100 lbs) that need to stay closer to the ground, like 50 lb fertilizer or a furry, four-legged friend with the help of a pet trailer insert.
