Pedal fell off kids bike?




peterngood


We bought a used bike and the left pedal fell off. I bought a package of new pedals and installed the left pedal (backward thread) but it too wore threadbare in a week and fell out. I drilled and tapped the pedal shaft with 8/32 thread added a washer and screw and the screw broke. I do not want to invest in a crank, any ideas please?


Answer
Obviously the crank threads are stripped. Assuming you're too cheap or broke (nuthin wrong with that - it happens) to buy a new crank (not that expensive for a kids bike), you should be able to garbage pick a bike with similar cranks.

Hand brakes vs brake pedals on kids bikes? Please read?

Which is better- buying a bike with hand brakes or foot brakes? Someone I know said you can flip over if you use hand brakes, are they dangerous? Thanks.


Answer
This depends on the age of the child. Notice that most smaller kids bikes, 12'' through 20" have the coaster (foot) brake. They also probably have one hand brake, usually not a very powerful brake. This allows the child to get used to the concept of braking by hand. Bikes with only hand brakes will have more powerful brakes. These are very responsive and generally work well when kids understand and are comfortable with their use. Engaging only the front hand brake suddenly will cause the bike to stop abruptly in the front end, causing the "endo" flip you are referring to. Always using the rear brake in conjunction with the front brake will prevent this dangerous situation.
