Abstract: The present invention relates to a steering assembly for a vehicle, comprising two rotatable rods, oriented vertically and having a wheel attachment on one end wherein wheels can be rotatably secured. The rods are connected to a first cross bar in such a way that enables the steering assembly to be attached to the vehicle frame and allows the rods to rotate. The rods are also rotatably attached to a second cross bar on the opposite end of the rod in such a way as to allow the rods to rotate. The rods are also attached to a steering mechanism in a manner that enables them to be manually rotated in unison and which in turn pivots the wheels and steers the vehicle.

Abstract: A smooth surface sliding system, which is adapted for incorporating with a ground vehicle impelled by a pedal driving assembly, includes a pair of supporting arms sidewardly and outwardly extended from the vehicle frame, a pair of driven units includes two driven arms movably coupled with the supporting arms respectively and two ski members coupling with bottom ends of the driven arms respectively for sliding on a smooth surface, and a steering control connected to the driven arms for shifting a downward force of a weight of the ground vehicle between the two ski members so as to increase a friction of the respective ski member with respect to the smooth surface.

Abstract: An internal combustion engine (E) has associated control devices (ECU, GSCU, SCU) for controlling the engine in a manner such that the engine delivers a driving torque (CM) which is variable in dependence on predetermined measured parameters, in particular on the position (&agr;) of the accelerator pedal (AP), and sensors (S1, S2) for detecting the position (&agr;) of the accelerator pedal (AP), and the rate of rotation (&ohgr;M) of the shaft (M) of the engine (E) or the forward speed (v) of the motor vehicle, respectively.

Abstract: A tracked vehicle (18), or a kit (10) for converting a standard bicycle (14) into a tracked cycle, includes a track assembly (22) with a bogie assembly (84) for riding on snow, mud, sand, etc. The track assembly includes a continuous track (60) movably disposed about a drive wheel (64) coupled to a frame (34) of the vehicle or bike, and a bogie wheel (68) disposed rearward of the drive wheel. The bogie assembly includes a compliant and resilient arm (80) coupling the bogie wheel to the frame of the vehicle or bike. The arm exerts a force against the bogie wheel, which forces the track towards the riding surface.

Abstract: A convertible snow cycle/bicycle apparatus for providing a vehicle which can be used all year long. The convertible snow cycle/bicycle apparatus includes a frame including a front portion and a rear portion; and also includes a steering assembly being attached to the front portion of the frame; and further includes a seat mounted upon the rear portion of the frame; and also includes a drive assembly including axle members being attached to the frame and also including a ski assembly being removably mounted to the steering assembly and further including a track assembly being mounted to the axle members.

Abstract: A kit for converting a conventional bicycle to a self-propelled snow bike. The kit includes a ski, an elongated member for mounting the ski to the front fork of a bicycle and a bias means for urging the ski to maintain a proper orientation as the ski pitches with respect to the elongated member. When the kit is attached to the front fork, the front end of the bicycle is raised so as to place more weight over the rear wheel for improved traction. Elevating the front end also provides greater ground clearance for the bicycle pedals so the bicycle may be pedaled even though the bike may settle into snow covered ground.

Abstract: A motor driven or pedal powered snow vehicle designed to emulate the steering and balancing characteristics of motorcycles and bicycles. The snow vehicle includes a frame, a swing arm, a track carriage, an endless loop track, a snow compacting ramp, an elongated steering member and a ski. The swing arm pivots upon the frame and angles downward behind the frame. The track circulates a fixed path around the track carriage. The track carriage extends forward from a pivot connection with the rear of the swing arm, and pivots vertically under the swing arm in scissors-fashion. The snow vehicle is suspended upon the track carriage using a single shock absorber and load-distributing bell crank. A snow compacting ramp attached to the track carriage compresses the snow ahead of the track. The steering member is like the front suspension fork of a motorcycle or bicycle, and is connected to the frame so that it rotates about a steering axis. The ski is mounted to the lower portion of the steering member.
