KEEP FALLING OFF
Back to questions
My 5-year-old son just started riding without
training wheels. We got him a second-hand, 18-inch
bike. Since then, the chain keeps falling off,
even when he is just riding around in the drive. It is very
frustrating when we are on family rides and I have to stop
every so often to put it back on.
Is there anything we can do to eliminate
My husband just bought a Diamondback
bike and the chain came off of it on his 2nd or 3rd ride.
There are no instructions in the manual on how to put it
back on. Is this something he can do or do we have to return
it to the store? He didn't purchase the extended warranty,
so I'm not even sure if they will fix it free of charge.
I suspect the same culprit for both
these bikes: The nuts holding on the rear axle have gotten
loose, causing the wheel to slide forward. This shortens
the distance between the pedals and the wheels, so the chain
stays loose and falls off.
For the kids (and possibly
adults) bike, you can use a wrench to loosen the screw-on
axle nuts even more. (See a photo here.)
Then slide the wheel into the proper position (it helps
to have an assistant hold it there), and tighten the nuts.
The Diamondback might have a quick-release
nut rather than screw-on nuts. In this case follow the same
procedure, except you use your hand, not a wrench: Open
the quick-release lever, loosen the nut on the other side,
move the wheel, then tighten the nut and close the lever.

Last, to fix a problem with a new
bike I wouldnt hesitate taking it back where I bought
it. If you got it at a bike shop, the staff should handle
it for free. If you didnt get the bike from a bike
shop, well . . . maybe next time you will.
