A transmission apparatus for a leveraged wheelchair may include a wheelchair, a driving mechanism, a driving wheels set, and a transmission wheels set. The driving mechanism has a first tube and a second tube which are pivotally connected, and with the relative movements between the first tube and the second tube, the driving wheels set can have forward or rearward rotation so as to achieve bi-direction driving effect of the wheelchair. Also, the relative movement between the first tube and the second tube is cooperated with a flexible connecting head such that a handle of the wheelchair is adapted to be forward and rearward pulled or rotated axially so to achieve the moving and turning actions of the wheelchair with one hand.

A step sporting equipment with a double transmission mechanism, wherein a transmission mechanism and a treading mechanism are located on both sides of a frame body respectively. Each transmission mechanism at least comprises a front wheel disc, a rear wheel disc and a driving piece. Each treading mechanism is connected to the corresponding transmission mechanism. When the user treads on each treading mechanism, each treading mechanism can compel the corresponding transmission mechanism to work. In addition, as the front wheel disc and rear wheel disc are linked by a driving piece, there is higher moving phase. Therefore, with two transmission mechanisms, the dimensional discrepancy of elements resulted from tolerance can be tolerated effectively, and the step sporting equipment can remain in normal operation.

A transportation apparatus (1) comprises a frame (12) having an engagement portion or receiving portion (14) adapted to receive one or more occupant support devices (16); and drive means (20) configured to enable an occupant of the transportation apparatus (1) to power, drive and/or steer the transportation apparatus (1). The drive means (20) has a first configuration or position and a second configuration or position, wherein the drive means (20) is closer to the engagement portion or receiving portion (14) of the frame (12) in the second configuration or position than in the first configuration or position.

A motorcycle includes an electric motor having an output shaft defining a motor axis, a rear wheel drivably coupled to the electric motor to propel the motorcycle, a swingarm rotatably supporting the rear wheel, and a frame. The frame includes a main frame member supporting the electric motor and the swingarm. A case of the electric motor is a stressed member of the frame between the main frame member and the swingarm. The swingarm is coupled to the case of the electric motor to define a swingarm pivot axis that is co-axial with the motor axis.

An individual chain wheel for a bicycle front crank arrangement for engaging in a drive chain includes a plurality of teeth formed on a circumference of the chain wheel and having a first and a second group of teeth. The teeth of the second group of teeth are arranged in an alternating manner between the teeth of the first group of teeth. Each tooth has a load flank via which force is transmitted between an adjacent roller of the drive chain and the respective tooth. Each tooth of the first group may also have at least one profile with an opening in the vicinity of the flank, in which a portion of an inner link plate of the drive chain, which portion protrudes beyond the roller, engages.

An exhaust system for a vehicle including a deep snow exhaust outlet defined by a driveline structural member of the vehicle. If the vehicle includes a turbo charger and an exhaust silencer, the turbocharger and the exhaust silencer are coupled together without exhaust piping therebetween.

A motorcycle conversion kit for a three wheeled motorcycle wherein the conversion kit of the present invention is operable to transition the motorcycle so as to traverse across a snowy terrain. The conversion kit of the present invention includes a pair of ski assemblies that are operably secured to the front rotor assembly of the motorcycle. The ski assemblies include rotor movement inhibitors. A swing arm assembly is operably coupled to the frame and includes a front portion and a rear portion. The rear portion has rotatably mounted thereto a snow belt drive wheel. The show belt drive wheel is superposed a snow belt of a snow belt assembly wherein the snow belt assembly is secured to the frame of the motorcycle. The kit further includes a fuel cell bracket assembly having support members mounted on opposing sides of the frame and having a compartment rearward of the motorcycle.
