HOW FAST CAN UR BIKE GO..? Ever get dis kinda silly question anywhere...? It depends on ur strength/stamina, U dumbass.. Foldie or Cervelo.. Aleoca or Tonino.. It logically depends on the rider, dumbass.. Give an 90 yr old a full carbon rig, he'll pass halfway... Give a "fit 38 year old me" the lowest end rig U can ever find, i can even chase a train anytime, brother.. So back to the question dumbass alwis ask "How fast can ur bike go"...? It all depends on YOU, dumbass.....!!
