| 摘要 |
A land vehicle or bicycle (110) is disclosed having a front wheel drive which includes an impulse drive mechanism and shock driver. The front wheel drive mechanism (140) includes a handle bar/driver mechanism (151) attached to an impulse drive mechanism (166). The bicycle (110) may be used such that the handle bar/driver mechanism (151) is fixed for use as a conventional bicycle or may be released by a twist grip (159) or thumb release (193) so that the bicycle may be driven by a drive mechanism (140). The shock drive mechanism (FIGS. 14-16) provides forward propulsion force due to the compression (308) and recoil (304) forces of a shock absorber (144) when the bicycle (110) encounters a bump, curb or other obstacle.
