I am having a problem with my bottom bracket for my BMX the bike is only 2 weeks old and has a knocking/clicking noise coming somewhere around the bottom bracket. But it only happens when I push on the pedal on the right side (sprocket side) and when I put pressure on it. I have tried new pedals but that's not it I have even took apart the bottom bracket and greased the bearings that didn't really need doing as the bike is only 2 weeks old. and I have also checked that all of the bolts are tight! I need help fixing this as it is really annoying and makes the bike feel bad when you ride it. I took the bike to a shop and they said that there is no play and that they would charge ?15 to have a look.
like someone said before call and see if they have a warranty my friend had this problem didnt care and a week later while jumping a 5 stair his whole bottom bracket broke free from the down tube. it was a very small crack in the down tube and the seat tube. but the bike had a small warranty and the company said it was there bad and they replaced his frame for free
I'd go to the company that made the bike. Hopefully there is a warranty. I race BMX Bikes and this is an unusual problem. Maybe the sprocket is chipping off pieces of the chain.
what 15 to look at itwhat a rip off they would problem brake it to and charge you for all new bottom bracket or tell you it can't be fixed and and try to sell you a new bike.i've had both these things happen to me.sounds to me like you have loose barrings and one is out of placejust take the whole bottom bracket off its and easy jobbut you may need a crank puller depending on the bike. and just check that the barring are correct or if sealed that its not cracked.
