Characteristics of Emerging Road and Trail Users and Their Safety

Hand Cycles (Stand-Alone)

Figure 11. Hand Cycle.

On stand-alone models of hand cycles, the pedaling motion is done with the arms (figures 11 and 12). Hand cycles are available with varying wheel sizes and with the single wheel in either the front or the rear. Hand cycles are also available that are designed with only two large wheels (one front and one back). Additional support, as required, is provided by small caster wheels that are mounted on each side just behind the seat. The caster wheels do not touch the ground unless the rider leans the bicycle to one side or the other.

Figure 12. Another hand cycle.

Most stand-alone hand cycles have a relatively long, narrow wheelbase, which decreases the rider's turning ability and increases the risk for capsize with sudden turning movements. Standalone models may offer a wide range of gearing and braking capabilities, depending on the type of use for which they are designed.
