My boyfriend bought a bike about 2-3 weeks ago and it was ok to begin with but the chain came off and got stuck! But now when we go out on our bikes his breaks squeek and its really high pitched and annoying why is this and is there anyway we can prevent it???
it could be that your brakes are to tight , or because its new it just hasnt broke in yet. it could also be because the brakes are cheap and rubbish. or there not on the rim properly. if you cant fix it take it back
