My son (teenager) has a second-hand Zombie bmx style bike - it's designed for kids, but as far as I can see the frame size is the same as any bmx. It needed a bit of messing around with, I've already replaced the wheels, which were fairly nasty pretend mags whose rims deformed whenever the tyres were inflated. What I'm now wondering is - the frame, like a lot of kids' bikes, is bulky and heavy. Is there a any reason why I couldn't transpose everything onto a different frame? Or am I missing an obvious incompatibility?
I love bikes, but as you can probably tell, bmx-s are foreign territory for me!
