The bike (10) comprises a frame provided with a front wheel (12) oriented by a handlebar, a saddle (39) and a crankset. The bike (10) further comprises two pivoting rear uprights (18, 19) each carrying a rear wheel (22, 23), the pivoting rear uprights being mounted by independent pivot links on the frame.

The crankset actuates two drive means (26, 27, 59, 60) independent of the rear wheels. The drive means of each rear wheel comprises a free wheel (59, 60). The drive means are configured such that, in a bend, only the rear wheel located on the inside of the bend is driven by the crankset, the rear wheel located on the outside of the bend freewheeling and not being driven by the crankset.

A front two-wheel leaning vehicle, including a handle, a steering shaft, a linkage mechanism and a load transfer mechanism. The load transfer mechanism includes a left-foot-placing part and a right-foot-placing part located between the left front wheel and the rear wheel, for left and right feet of the driver to be respectively placed thereon. The load transfer mechanism transfers a load to the left and right portions of the linkage mechanism through the left-foot-placing part and the right-foot-placing part, or through the right-foot-placing part and the left-foot-placing part, respectively. The steering shaft includes a handle adjusting mechanism configured to adjust, with respect to the left-foot-placing part and the right-foot-placing part, at least one of a handle height, which is a distance from a midpoint between the left and right front wheels to the grip, or an offset amount of the handle with respect to a rotation axis of the steering shaft.

An electric assist vehicle is described, which may have a cargo area, a drivetrain including an external crankset and an electric motor, and a speed control system. The speed control system automatically limits the maximum operating speed of the vehicle based, at least in part, on a load mass (e.g., a gross weight) of the vehicle and/or the cargo area of the vehicle. Limiting the speed includes, for example, reducing the power of the electric motor and/or increasing a braking force on the vehicle.

An electric tricycle with a tricycle frame, at least two pedals, and an electric motor. The tricycle frame has a steering assembly with handlebars and a front wheel and a rear wheel assembly with two rear wheels mounted on a rear axle. The pedals are rotatably coupled to the rear wheel assembly. The pedals have an engaged configuration where the pedals are engaged with the rear axle and a disengaged configuration where the pedals are disengaged from the rear axles. The electric motor is mounted on the rear wheel assembly and is electrically coupled to a battery. The electric motor is configured to engage with the rear axle when the pedals are in the disengaged configuration. The electric motor may have a forward clutch to rotate the rear axle in a first direction and a reverse clutch to rotate the rear axle in a second direction opposite the first direction.

Systems and methods are disclosed herein for an interchangeable electric scooter with seating option for 2 passengers is proposed. The assembly provides various advancements including but not limited to a glossy finish, a rectangular front frame member, an aerodynamic manual brake fin, a communication device support member, floor and front panels having multiple colors and designs, On/Off digital locking system, front and back cameras, solar panel, retractable umbrella, cell phone charging spot and holder, Bluetooth connectivity, GPS enabled, smart helmet, an integrated router forming a Wi-Fi hotspot, a daytime running lamp and back lit lights, number plate, a help switch, a sound system, a camera for livestream and social media synchronization, a communication device charger, an integral GPS.

A tiltable vehicle is configured to transform between an autonomous mode and a rideable mode by pivoting the handlebars and steering column of the vehicle about a pitch axis. In the autonomous mode, the steering column is folded back toward the chassis and a tiltable chassis of the vehicle is prevented from tilting. In the rideable mode, the steering column is unfolded and the chassis is free to tilt. In some examples, a tiltable vehicle includes features beneficial for vehicle-sharing, such as parking devices or a basket. These features may be included on any suitable vehicle and are not limited to use on transforming vehicles.

A Steerable Crank System including a Steerer Base firmly connected to the chassis/mainframe of a machine, said Steerer Base containing and supporting Grooved Cog Wheel situated in-line and parallel to the power driving direction in a manner that allows said Grooved Cog Wheel to rotate around its axis and drive the machine power, said Steerer Base containing and supporting a Fork in a manner that allows said Fork to rotate around its main axis and by that rotation movement it controls the steering, said Fork containing a 2.sup.nd axis supporting and housing a Crank Shaft in a manner that allows said Crank Shaft to rotate around its own axis, on said Crank Shaft attached a Butterfly Connector, said Butterfly Connector coupling together said Crank Shaft and Grooved Cog Wheel.
