A water amusement system is described which includes a number of different water park rides. The water amusement system may include a water fountain system. The water fountain system includes a roof configured to turn in response to directing a stream of water at the roof. The water amusement system may include a water carousel. The water carousel is a carousel which is configured to float on a body of water. The water amusement system may include a musical fountain system. The musical fountain system is configured to spray water, play music and / or provide visual effects. The water amusement system may include a water powered Ferris wheel. The water amusement system may include a water powered bumper vehicle system. The water powered bumper vehicle system is configured such that the vehicles are preferably propelled by streams of water produced by water nozzles arranged about the water bumper vehicle system. The water system may include a boat ride system. The boat ride system includes a number of boats which are preferably towed by a rotatable base. The boats may also include steering devices and participant interaction devices. The water amusement system may also include a water train system. The water train system is a train system which is propelled by a water propulsion device.

To provide an electromotive power assisted bicycle enabling an aerobic exercise with a light weight and simple mechanism, an electromotive power assisted bicycle 1 comprises a pedal effort detection means for detecting a pedal effort (99, 126), a drive unit 13, a force combining mechanism for transmitting a rotational torque of a speed reducing unit to a drive shaft, and a heart rate detection sensor 254. The drive unit 13 comprises an electric motor 37 and a speed reducing unit 35 having an electromagnetic clutch 250. In a mode enabling the aerobic exercise, if the detected pedal effort is higher than the pedal effort level enabling the aerobic exercise, the drive unit 13 drives the electric motor 37 under the condition of the electromagnetic clutch 250 being engaged and thus assists the pedal effort with the electric force. If the detected pedal effort is lower than said pedal effort level, the electric motor is turned off under the condition of the electromagnetic clutch 250 being engaged, and thus applies a loading force to the pedal effort by the rotational resistance of the motor. The pedal effort level can be adjusted in response to the detected heart rate of the rider.

In an inverted pendulum type vehicle configured to travel on a ground surface while maintaining an upright posture under an inverted pendulum control, comprising a base frame supporting a propulsion unit, the propulsion unit including a main wheel configured to roll on the ground surface, and a seat unit provided on the base frame for supporting hips of a rider, the seat unit includes a saddle having at least a center located ahead of an axial line extending between a rotational center line of the main wheel and a gravitational center of the inverted pendulum type vehicle. Thereby, even when there is an obstacle on the ground surface behind the vehicle, the main wheel rolling on the ground surface is prevented from coming into contact with the obstacle, and the boarding of the rider on the vehicle is facilitated.

A wheel with a self-contained drive mechanism is provided to propel (or assist in propulsion of) bicycles, tricycles, and similar vehicles. The wheel preferably takes the form of a shock absorbing detachable wheel, which is readily received within the dropouts of a bicycle frame or fork to be attached therein by a standard quick-release mechanism. Thus, the wheel may be added to (or removed from) preexisting standard bicycles and the like.

A scooter device propelled by side to side movement of a user that includes a frame structure through which at least a front wheel is coupled to two direction biased rear wheels. The frame structure may have a foot placement platform that extends laterally between the two rear wheels. The platform may extend over half of the distance between the rear wheels and / or be substantially continuous for that distance. Various platform embodiments and frame structures, including rigid and flexible, are disclosed, among other aspects.
