Just got a beach cruiser bike. 10 speed I think. is there anyway to make her a 20 speed?

I don't know call Ricks bike they should be able to help you. Good luck

Unless you're beach cruising in the San Francisco hills, you definitely won't need that many gears for that style bike. Save calling Rick's for when your wheel need alignment or your brakes are coming loose.

You need to call them?Rick's Cycle Shop on Allen Street
