Rad Power Bikes RadRover 6 Plus: real range, hills and charging
A 180 lb rider on the Rad Power Bikes RadRover 6 Plus at 16 mph with relaxed pedaling over rolling hills (±2%) on pavement can expect about 40 miles per charge (32–47 mi), using 15.3 Wh per mile. The brand claims up to 45 miles. That is about 88% of the claim. On throttle only over hills it drops to about 27 miles. It is discontinued; of the current fat-tire e-bikes we track, the lowest-priced that goes as far is the Gotrax Tundra ($1,299, about 56 miles).
