A vehicle includes a vehicle frame including a first frame rail, a second frame rail spaced cross-vehicle from the first frame rail, and a middle frame rail between the first frame rail and the second frame rail. The first frame rail and the second frame rail each have a vehicle-inboard side facing toward the middle frame rail. The vehicle-inboard sides each define a plurality of notches. The middle frame rail has a downward side facing downwardly and perpendicular to the vehicle-inboard sides. The downward side defining a plurality of notches. The vehicle frame has a rear cross-member and a front cross-member spaced vehicle-forward of the rear cross-member. The rear cross-member and the front cross-member are between the first frame rail and the second frame rail. The notches of the vehicle-inboard sides and the notches of the downward side are between the rear cross-member and the front cross-member.

The HOVERTRIKE is an Electric Standing Trike, it is a light sport and recreational vehicle with the capabilities of riding on the road and off the road. It is equipped with three wheels and three motors, one inside each wheel. At the front, it looks like a standard e-bike with a hub motor inside the wheel and a standard bicycle fork with suspension, brakes, and handlebar. The back frame is equipped with a hub motor, independent suspension, and disc brakes for tilting and cornering.

Some implementations can include a zero turn radius utility vehicle that is operated in a standing position by an operator using foot controls provided on the utility vehicle. Accordingly, the operator's hands are free to operate handheld equipment (e.g., a line trimmer, edger, blower, etc.) while the operator controls the utility vehicle via the foot controls. Further, the utility vehicle may have a single third wheel (and no mower deck or other deck or protrusion) extending from the front of the vehicle frame so as to minimize any protrusions to the front of the vehicle, which can permit the operator to work on the ground in front of the utility vehicle using handheld equipment without interference from a mower deck, while remaining in a standing position on the utility vehicle and being able to simultaneously control the utility vehicle (via foot controls) and perform work with handheld equipment.

A free wheel mechanism includes a basic assembly, a fastening member, a sleeve, a rotating member, a first elastic member, and a second elastic member. The basic assembly comprises a base, a guiding rod, and a free wheel. A guiding hole is defined in the fastening member to receive the guiding rod. One end of the sleeve is received in the guiding hole. The rotating member is positioned in a through hole of the sleeve. The first elastic member is coiled around the guiding rod, and opposite sides of the first elastic member resist against the base and the sleeve on opposite sides. The second elastic member is received in the through hole, and opposite sides of the second elastic member elastically abuts the rotating member and the guiding rod on opposite sides. Meanwhile, a moving apparatus with the free wheel mechanism is provided.
