Hallo ppl. I have been on vacation in florida, and i just realized when i got back that i need a bigger and faster uni!! My 20 inch is a little slow (o___O) can you sugest an affordable uni? And mebe sum tips on riding bigger ones and mounting. thx 
What are you looking for? Commuter, muni, XC?
Looking for speed eh? I’m gonna have to suggest a coker, or at least a 29" they vary in prices depending on your skill and such. you’ll get the mount on a 29 er fairly easy, but the coker takes a bit more practice
Want a fast uni for free!!!
Pedal faster. It ain’t the uni, it’s how fast you pedal.
