Absolutely love the K820 bike! It's very beautiful, very sturdy, the battery goes for a very very long time on a charge. Everything feels so quality built. I'm not just being a fan boy but I seriously look forward to riding my K820 bike every day after work. I wanted a classic looking mountain bike and this fits perfectly.
The seat is way more comfortable than I expected it to be, and the nice wide pedals reduce pressure points on the feel. The kick stand is very solid, shocks are smooth, disc breaks work perfectly, didn't have to dial in anything right out of the box it was prefect. Very easy to put together, it came mostly assembled. Only took a few minutes, that was also a pleasant surprise because I expected it to take more time.
Thank you for providing a great product! It's scary spending your hard earned money on something you blindly "hope" comes through, but you exceeded my expectations!
