The "RADPower Bike" will go 50 miles in "pedal Assist" mode and 25 miles "throttle" only per charge. ..probably for a rider around 190 pounds. There is a "Table" on page 19 of the owners manual that you can download from their website - www.radpowerbikes.com
Expected range at my weight 230 pounds 20 miles "throttle" only to 40 miles pedal assist.
The battery capacity Display is a rectangular box with "F" at left end and "E" at the right. Inside the box are 5 squares. So far after 440 miles on flat ground with a 8-10 mph headwind I'm averaging 16 miles per square. Most used so far are a "square and one quarter". Time to recharge about 45 minutes. Battery is charged after every use.

Once I lowed the air preasure down to 30 pounds I had no problem negotiating in the sand. This is not an Offroad bike though as the tires are too narrow - 2.3 inches. The RAD "Rover" has much wider tires and a 3 speed motor . The Rover is much better suited to offroad riding.
It was fun to ride around the camp at the rally and will definitely take it out there again.
