Had my Cyberbike Mullet for over a year now. Ride streets and dirt tracks here on Oahu. The bike is great. Awesome. Well balanced and enough power for anything, plus the large battery lasts a long time. So far nothing broken or stopped working. I ride almost every day and charge once a week. Great components, but I did exchange saddle, pedals and grips for little additional cost. Its a perfect e-MTB. The only drawback, its heavy, like most similar bikes are.
