I have a dilemma, after a long break I bought a 25 inch frame Puch Prima 12 speed but was then given a Peugeot Super Competition 12 vitesse. I can only keep one of the bikes, but which one should go?
Take the best components off each and build a new bike, or, if you don't fancy that. Adjust both bikes so they are more or less the same and ride them as cce suggested. Keep the one you prefer. If you can't decide. I had a Puch once and I'd go for the Peugeot
