    Venice Ruff Cycles Chopper Build

    I just scored a Ruff Cycles frame & some wide custom wheels with a front Shimano roller brake... I'm thinking this bike will be a perfect platform for a 212cc Predator engine. (^) My plan is to powder coat it something special & install a custom gas tank... I'll post more pics as it happens. :)
