Wheelbike
developed by Gallis-Tech, wheelbikes were popular sport vehicles which found a niche on worlds were repulsorlift engines failed to work properly. The wheelbike was a large wheel, which was propelled by an internal mechanism. The rider sat within the wheel and controlled it with a set of handlebars. Balance was an important part of riding a wheelbike, since the rider's center of gravity was well above the ground. The civilian model of the wheelbike was even harder to control, since the passenger sat behind and above the operator. In the military version, the passenger seat was replaced with a repeating blaster. A series of gyrostabilizers helped keep the wheelbike upright as it moved across varied terrain.
