A hybrid pump-action vehicle and therapy device may include a pumping arm attached to a lower pump-action assembly. As the pumping arm is actuated, the lower pump-action assembly moves forward and rearward in response to the pumping action and powers movement of the vehicle. The lower pump-action assembly may be releasably connected to the pump arm so that the pump arm can be disengaged from the pumping action but still be usable for steering. A motor may also be provided to provide assistance or full power to the vehicle based on a user-selectable amount of assistance. And finally, the vehicle may be configured such that it can be collapsed to a fraction of its operating footprint to enable easy transport and storage.

An electric snowmobile that performs heat exchange with a simple structure is provided. The electric snowmobile includes a body frame, a driver's seat, an electric motor, a ski, a track mechanism, a battery, a cooling unit that cools fluid at least in accordance with outside air, a first heat exchange unit that performs heat exchange between the battery and the fluid, a second heat exchange unit that performs heat exchange between the electric motor and the fluid, a first flow path for delivering the fluid cooled in the cooling unit to the first heat exchange unit, a second flow path for delivering the fluid cooled in the cooling unit to the second heat exchange unit, and a third flow path for delivering the fluid heat-exchanged in the first heat exchange unit and the fluid heat-exchanged in the second heat exchange unit to the cooling unit.
