For the price, this bike rocks!

So far I’m very pleased with the new bike. It s a lot of fun to ride and plenty of power for my needs. 20 mph has been plenty fast to. I’m 6’2 225 lbs. and it gets where I need to go. I did run it in the woods a few times already and was glad it wasn’t faster or I would have definitely went down lol, I feel I am a pretty competent rider. Hopefully it keeps doing what it should for a long time to come.

Bought this to take with us this summer on vacation in our RV. Wanted to give it a try at home before we left. It was easy to assemble with no damage at all in shipping. As we live on 5 acres our road is just desert packed sand and rock. Wife and I both had to get the hang of how quick it moved with pedal assist. We did have to adjust the derailer to get it to shift in all the gear. Once we did that all we can say is how quick it is. Fact is we ordered another one so we both can ride together.
