For those of you athletes who are always looking for a new challenge to test your skills and hone fresh talents, there is always a new mountain to climb. Riders who are adept in the saddle - the saddle of a bike or a unicycle, that is - and those who have already tried their hand at mountain riding, trial riding, freestyle riding and others, may find a fresh challenge by learning to ride a minibike, like the UDC Minibike available at Unicycle.com.
