Happyrun support and parts are at the top of the iebike industry. During my warranty I experienced a very rare problem and I was upset until I talked to support.They had me smiling in under a minute by assuring me with professionalism that I was fully covered and I would be back on the road in no time. The part was ordered before I hung up the phone. Even after my warranty was up they have been there with the same professional care and speedy delivery. Im finishing up year 3 on my G-100 and Happyrun has been there all the way. My hats off to this company for producing and backing their great products.

I had a problem with product and received response with forward.action plan within 24hrs. Action plan was to the point , helpful, and at no cost to me. Resolution was prompt, however shipping to fix problem was slow. All human interactions were amazing, I'd never wish problems on another customer but if you needed to reach out you'd be able to find great help. Thank you team, -Mr.Tran

The website was easy to navigate, gave all the information needed for an informed decision and helped to make the process of choosing the e-bike easy. The delivery was faster than I had thought it would be, the bike was of a higher quality than others that I have looked at and the assembly was much quicker than I imagined that it would be. I have been riding it to commute to work and find that it performs extremely well in city traffic. After only a week of use, I am extremely pleased that I chose the Happyrun G70 Pro for my e-bike.
