Improve your balance while enjoying a whole new form of exercise with the Raleigh MTB 20-inch unicycle. The device offers such features as a double-bolt seat clamp that prevents slippage, cotterless three-piece cranks, and a padded saddle for maximum comfort. The most important feature, however, is the extra-large, knobby off-road tire, which measures 20 by 2.5 inches and is ideal for riding on both city streets and rougher gravel or dirt trails.
