Bike Chain help?

Question

when i ride my bike (bmx) the pedals for a couple of seconds feel like they r not attached to the chain. meaning i keep pedalling but there is no restriction from the chain so my knee hits the handle bar and it hurts but then like 2-5 seconds later it reconnect and i can keep going what the problem and how do i fix it. its a brand new bike i got yesterday

Answer 1

Where did you purchase this bike? Was it at a bike store? Or a large box type store? In either case, I would take it back to the store immediately. There are a couple of potential problems here. I'm assuming that the chain is not coming off since you would probably not to able to recover so quickly. You either have a defective crank or defection freehub. Take it back to the store.

Answer 2

The little prongs inside the rear sprocket are not catching, take it back for a replacement. If you can't then spray some wd-40 into the sprocket, not the axle, this will free up the springs inside.

Answer 3

Does'nt sound like a chain problem to me. The rear hub maybe defective. If it's brand new, I'd take it back to the store you bought it from.

Answer 4

Tell your mommy to take you back to the store with the receipt and the bike and explain your problem to the stores owner. Good Luck!

Answer 5

Hey man. Seems they gave you a busted free wheel. Nothings wrong with your chain. Return it asap and ask for a replacement

Answer 6

- chain too long
- rear wheel is loose in horizontal drop-outs, making chain loose
- broken freewheel
- front chainring is not connected properly and is slipping

It doesn't really matter what the problem is, take it back and get it fixed.
