In Amsterdam, one thing is sure: It is all about Bikes!
Want to pimp your ride? I found a website to accessorize your bike.It is called BikeCap. Everything is super Kitschy I have to admit... but I feel that going for fun stuff to 'dress up' your bike is totally acceptable (especially if it's useful)!
