Crank spin question
Last night I was doing some bike maintenance on my daughter's BMX bike and my Giant. With the chain on I noticed that the crank on the bmx would spin around several times with just one big backwards throw, while the crank on my bike would only spin about 1 1/2 times around. Is this normal?
