Pros:this bike makes all your superman dreams come true
Cons:extremely dangerous
Time Used:Just Once
Comments:DON'T BUY THIS BIKE While I mas riding my new trek 820 for the first time it was not a good first impresion and it would be the last.
While rinding I heard a snap then I tried hitting the brakes. But 2 late I got thrown over the handle bars and I was superman flying in the air straight at the cement curb. My head smashed into it (luckly wearing my helmet) and I got all scraped up, was bleeding, ruined my new tee-shirt, and bruised my rib.
Then I called the company and they have heard about the problem before. This is dangerous because they kow there selling a bad bike.
They said that if you pick up speed this usually happens. That means I can't ride the bike I just have to walk next to it while holding it, fun. Luckly they sent me 2 models up and a new helmet because mine broke in the superman act. Don't buy this bike and if you do wear body armor.
Rating: Recommendation:No I would not recommend it to a friend
