Wheel and Tire

The Radwagon 4 is the latest version of Rad Power’s flagship cargo bike. It was released in 2020 and features some significant upgrades from the previous model, the Radwagon 3. The most noticeable difference is the wheel and tire size. The Radwagon 4 has custom-made 22″ x 3″ tires that are wider and smaller than the standard 26″ x 2.3″ tires on the Radwagon 3. According to Rad Power, this change lowers the center of gravity and improves stability and handling, especially when carrying heavy loads.

Frame design

Another difference is the frame design. The Radwagon 4 has a redesigned frame that is stronger and more durable than the Radwagon 3. The frame also has more mounting points for accessories, such as front and rear racks, baskets, bags, fenders, and passenger seats. The Radwagon 4 also has a telescoping seat post that can accommodate riders from 5’1″ to 6’4″, while the Radwagon 3 has a fixed seat post that suits riders from 5’2″ to 6’2″.
