Bicycle or Unicycle?

This Hammacher Schlemmer catalog exclusive transforms from a comfortable-riding traditional bicycle to a fun and thrilling unicycle, with a single twist of its lock-tight handle. Used as a bicycle, it is a sturdy, reliable means of pedal-powered transport, but when front section is detached, the rider is perched atop a lightweight, highly maneuverable unicycle.

No longer confined to circus performance, unicycle riding is widely recognized as an excellent form of travel, exercise and entertainment, and with some practice, riders will be able to turn on a dime and perform a whole host of tricks. In fact, a switch built into the handlebar loosens the crossbar’s grip on the seat post without releasing it, allowing the front section to swing from side to side, independently of the back wheel, making tricks easier to perform.

The bicycle is equipped with front-wheel brakes, as well as front and rear reflectors. Helmet and safety gear recommended (not included). For ages 16 and up. $150. www.hammacher.com
