Whats up guys? I recently bought my son his first bike, I decided to buy him a cheap bike until he gets the hang of it and buy him a better one later on. Just so you know its a Hyper Spinner from Walmart, for a 10 year old I think its decent cause its a 26/9 gear ratio and its kinda light once I took all the extra crap off of it, my son loves it and will love it even more when I start upgrading it. The only real problem it has is when you jump a curb or a speed bump it makes a funny sound when you land, like as if the bars are slipping, it doesnt do it all the time but enough to make it annoying, I told my son not to worry about it because I tightened and checked everything so im hoping maybe once the bike is broken in it will go away, any comments or recomendations? Besides get a new bike, because im not buying a 10 year old a $500 bike so some jackasses can steal it. Thanks!
