Are bicycle crank arms universal?
No, cranks are not generally always interchangeable, but you probably can transplant the crank from the broken bike. First, do both bikes have 6, 7 or 8 sprockets in the rear cluster? If so, they use the same chain width and the spacing between the chainrings will be the same.
How do you know what size crank arm to get?
