so much fun, although i will point out that usually when i ride coed y brenin on a normal bike my legs feel tired, on the e bike i tend to ride further so i still get the leg ache at the end of the ride, i tend to use only eco mode up there as those hills can really eat in to the battery, but the thing i notice most about riding the e bike there is the upper body work out aches, at the end of the day the e bikes are much heavier, so man handling them down the rocky rough trails is more of a work out there, i feel like i have been doing bench presses, something i don't get riding my orange 5.
