We took an Optibike R22 Everest, Optibike Type 1, and Bosch CX equipped E-Bike to a steep dirt hill climb.
The hill is a 46% grade and has a soft loose dirt surface, certainly not an easy climb to do!
The same rider took all 3 E-Bikes, as well as a standard pedal mountain bike up the hill. We did multiple runs of each bike to find the best gearing, and each E-Bike was in its highest power assist mode.
Check out the video to see how each bike did!
