A three-dimensional folding frame is disclosed including a first pivot portion for providing a front folding wheel frame with movable folding; a second pivot portion for providing a rear folding wheel frame with movable folding; a third pivot portion for providing a handlebar vertical rod with rotatable folding; and a fourth pivot portion for providing a crossbar with rotatable folding. The crossbar includes a first folding arm and a second folding arm; the first folding arm is movably connected to the front folding wheel frame by means of the first pivot portion; the front folding wheel frame rotates about the first pivot portion and can move relative to the first folding arm; the second folding arm is movably connected to the rear folding wheel frame by means of the second pivot portion.

Techniques are disclosed for a rear triangle configuration for a micromobility transit vehicle. In accordance with one or more embodiments, a micromobility transit vehicle is provided. The micromobility transit vehicle may include a seat tube, a wishbone seat stay including a fork and post connecting the fork to the seat tube, a collar connected to the post and rotatable about an axis defined by the post, and a lock cable connected to the collar to rotate about the post. The fork may be connected to a pair of chain stays, such as via a pair of rear dropouts, to extend around a portion of a rear wheel. The rear dropouts may include a vertical dropout structure and positively lock to an electric motor, such as via complementary structures. A channel may be disposed in a rear dropout to receive a motor cable running to the electric motor.

A luggage scooter has a middle frame, a front wheel section, a seat section, and a rear wheel section. The front wheel section has a front wheel frame pivotally connected to the middle frame at a front wheel frame joint. The front wheel frame is mounted to a steering joint. The steering joint is mounted on the middle frame. The steering joint provides steering in both a left and right direction. The front wheel frame joint provides the front wheel frame with configurable position between a stowed position and a deployed position. A front wheel is mounted to the front wheel frame at a front wheel support. A rear wheel section has a rear wheel frame pivotally connected to the middle frame at a rear wheel frame joint.

An electric balance bike includes: a bike frame having a seat at an intermediate position thereof, a head tube at a front end thereof, and a rear fork at a rear end thereof; a front fork connected to a lower end of the head tube; a handlebar connected to an upper end of the head tube; a front wheel connected to the front fork; a rear wheel connected to the rear fork; an actuating assembly arranged between the bike frame and the rear wheel, the actuating assembly having an actuator located under an intermediate section of the bike frame, a driving member located at an axle of the rear wheel, and a driving belt that are wrapped around the actuator and the driving member; and a rechargeable lithium battery detachably connected to the actuator.

Disclosed is a folding bicycle, including: a front wheel, a rear wheel, a handlebar, a main frame, a support frame, a pedal mechanism, a first safety clamp, and a second safety clamp, the first safety clamp being configured to secure relative position between the support frame and the main frame; and a second rotating shaft is disposed between the through-hole and the position where the main frame joins with the handlebar. The folding bicycle disclosed offers an advantage of portability.

An electric bicycle includes a frame that has a concave or arc shape. The bicycle also includes two wheels—a front wheel and a rear wheel, with each wheel being connected with an end portion of the frame. A battery-powered electric motor may be connected with the rear wheel to drive the rear wheel and propel the bicycle forward. The battery may be rechargeable. The speed of the bicycle may be controlled by the operator moving a lever with one of their feet. A rotatable knob located on the frame may be used as a cruise control speed setting device. The electric bicycle may be steered by the operator using their feet resting on a pair of foot pegs that are attached to or connected with the front wheel. The electric bicycle may include a regenerative braking system or a friction braking system.

The modular bike is a chainless biking device that may be quickly converted from a road bike to an all-off-the-road bike or a racing bike. To accomplish this, the device includes a frame, a drive box, and a plurality of wheels that are detachably attached to one another in an efficient and stable fashion. The device utilizes a hydraulic drive mechanism, which is more efficient than a chain drive mechanism. Further, a quick release mechanism associated with the wheel hubs of the modular bike enable users to quickly change the wheels from the frame for tire and/or spoke repairs. Additionally, the offset arrangement of the drive box and the frame along with the quick release mechanism of the wheels enable users to transform the bike to various configurations to match to the purpose/terrain of the ride etc.
