I have a couple of question for bike mechanic gurus...

1) Can front fork be changed? I've asked couple of people and they said that I can't change the fork on these cheap bike. I don't have any spec on current setup - so if you know what the setting is, it would be great.

2) Crankset - When I'm doing top speed, I can't pedal fast enough to match the speed. What is the setup on Ezip and if I could move up in crankset.

Thanks for your help.
