When we need to drive to the trailhead but have a heavy E-bike, the RockyMounts GigaWatt E-Bike Hitch Rack is the answer. The GigaWatt can accommodate two E-bikes weighing up to 80 pounds each, and the wheel holders work with 20 to 29-inch tires up to 4. 5 inches wide so that we can load up nearly any bike. This hitch rack includes a ramp to load the E-bikes with so we don't have to pick them up, and an integrated lock secures our bikes to the rack and the rack to the car so we have peace of mind while traveling. Lastly, RockyMounts designed this rack to fold up when not in use and can fold down for easy access to the trunk.
