I have been riding this bike for over a year. The other riders in my group have Specialized S-works, Intense, and other high end ebikes and the bulls holds it's own. Plenty of power to get my 200+ pounds up mountains and great suspension to handle rough trails. No battery anxiety due to one of the biggest capacity batteries available. Great price and great bike.

This bike is Sweet! I’ve been riding the Copperhead AM 3 for almost a year now and it’s a blast! I started mountain biking way back in the 80s and biked constantly until about 10 years ago when it stopped being as fun. The Copperhead AM 3 with its dependable Bosch CX pedal assist motor has put the fun back into riding and I’m getting into the woods a few times a week. This Bike has been a game changer for me and I highly recommend getting one and getting back out there.
