1. A pedal driven cycle comprising:
a cantilevered frame member coupled to a power input sprocket and a driven sprocket;
a belt drive connecting the power input sprocket to the driven sprocket;
a side mounted rear wheel releasably coupled to a multi-speed gear hub that is coaxial with the side mounted rear wheel, wherein the multi-speed gear hub is coupled to the driven sprocket; and
a tension adjustment mechanism coupling the driven sprocket to the cantilevered frame member, the tension adjustment mechanism being slidably moveable along at least a part of the cantilevered frame member thereby to adjust a tension in the belt drive, and comprising a first member and a second member slidably moveable along at least a part of the cantilevered frame member, wherein the first and second members are arranged on opposing sides of the cantilevered frame member and clamped to the cantilevered frame member.
