With all decent chaps at least thinking of being a bit greener and considering doing a bit of excercise, it seems that getting a bike would be the best thing to do if you want to kill two birds with one stone. Instead of going for some dull mountain bike, or worse still, a racer, why not get all P.I.M.P. when cruising around the street.
The company Stiletto make a bunch of dragster style bikes that look cooler than your average bike and not only that, you might turn the heads of a few ladies on it. With prices averaging around £350, the only drawback seems to be that they are primed for ne’er-do-well’s to pinch them, and I don’t think you’ll be doing much cross-country on ‘em.
