Terrible Terrible. Bike pedals hit the ground. Does not hit 20 mph. They guarantee returns but do not have a functioning phone line and do not respond to emails.

Terrible quality, heavy components are supposed to be durable but they break easily Got a flat that made the bike impossible to move any distance without becoming exhausted. Probably my fault due to not putting the spacer in but the front wheel doesn't roll well with it and that's that one of the reviewers ended up doing during assembly. Then it got stolen when I came back for it. That part isn't exactly the fault of Happyrun, of course, but I will fault them for making the bike so cumbersome to move in this circumstance. The thing is, it's a great bike (especially for the price) if you know what you're doing with respect to being a bike mechanic, but it's very easy to run into problems if you're an amateur like I imagine the target market is. Be warned!

Wonderful e-bike Wonderful e-bike! After sixty years of riding motorcycles and mountain bikes, I was finally able to get on my first fat tire E-bike! I done a lot of research and there are lots of possibilities. I found the big, powerful, long-distance, fat tire I was searching for!
