Tricky Wheels

The Trikke (pronounced 'trike', not 'tricky', though it certainly is that) is what would happen if a bike and a skateboard defied societal conventions and had a baby. It's got three wheels and no pedals, and to make it go you need to rock it back and forth and side to side in a motion that's similar to in-line skating and skateboarding. Once you get the hang of it - and you'll want to practice on a flat driveway or empty parking lot where your neighbors and passers-by can't make fun of you - the Trikke becomes addictively fun and is a great full-body workout to boot. $149-$249. www.trikke.com
