Had a little trouble with getting it together. The chain was off completely and knotted. I had to take the derailleur completely off and put back on. Then the bike would not shift right but I then watched a video on rear derailleurs and got the bike to shift to all the gears. I will be taking it in to bike shop in a week when they can get me in to look over and adjust everything and make sure everything is safe. 100 dollars per hour! After first ride, I am eagerly waiting on new seat and suspension seat post. Something is clicking in the front. I think it is the brakes or rotor. But rolls smoothly and first ride was extremely satisfying! Where I live, it is all hills. Can't ride anywhere without a big hill and many little ones. This bike makes the hills disappear! Rode in Eco and Level one: All I need! Thanks Juiced Bikes!
