A bicycle assembly can include a front or rear suspension system with a shock absorber. A front suspension system can be a suspension fork. A rear suspension system can include a rear shock absorber. The shock can have a shock body and a pressurized main air chamber within the shock body to act as an air spring. The shock can also have a valve configured to receive a pump for adding air to the main air chamber. A secondary air chamber and a control member can be used to reduce the pressure within the main air chamber by venting the secondary air chamber to the atmosphere.

A dynamic training system provides elevated load and energy demand on a rider of a moving bicycle out on the road or track. Resistance to movement of the bicycle is provided by a resistance unit which may include an eddy current brake. A processor may generate a control signal that adjusts the resistance to replicate the effort of riding a predetermined course or training protocol. Multiple riders at different times or locations can compete on a common virtual course. A stronger rider can be restrained by a heavier imposed load to keep pace together with a weaker rider, without compromising total power expenditure to keep the riders together.

A personal mobility vehicle, such as a scooter, includes at least one battery and motor for powering at least one driven wheel. The vehicle also includes a braking assembly configured to isolate the motor from the at least one driven wheel such that power is terminated from the motor to the at least one wheel in response to a user engaging a braking assembly of the vehicle. The vehicle can include a switch or position sensor that interacts with the braking assembly to initiate the isolation of the motor from the at least one driven wheel and the switch or position sensor preferably is inaccessible to the foot of the user.

A foldable structure includes: a first folding seat; a second folding seat rotatably connected with the first folding seat and including a position limiting boss; and a locking assembly including a locking buckle and an unlocking part connected with each other, which are rotatably connected with the first folding seat, respectively. When the foldable structure is in an unlocked state, and the first folding seat rotates around the second folding seat in a first direction, the locking buckle moves along with the first folding seat to be engaged with the second folding seat and the unlocking part moves to abut against the position limiting boss, so that the foldable structure is switched to a pre-locked state where the position limiting boss prevents the unlocking part from rotating around the first folding seat to unlock the locking buckle.

A two-wheel, self-balancing vehicle is disclosed. In one aspect, the two-wheel, self-balancing vehicle comprises a first wheel and a second wheel, the first wheel and the second wheel being spaced apart and substantially parallel to one another. The two-wheel, self-balancing vehicle further comprises a foot placement section connecting the first wheel and the second wheel. The two-wheel, self-balancing vehicle further comprises a set of position sensors in the foot placement section, the set of position sensors configured to generate inclination angle signals and velocity signals of the two-wheel, self-balancing vehicle. The two-wheel, self-balancing vehicle further comprises a first gravity sensor and a second gravity sensor in the foot placement section, the first gravity sensor and the second gravity sensor configured to generate weight signals and gravity angle signals. In addition, the two-wheel, self-balancing vehicle comprises a control logic configured to output control signals that control the movement of the two-wheel, self-balancing vehicle in response to the inclination angle signals, the velocity signals, the weight signals, and the gravity angle signals.

A recumbent cycle includes a seat for a rider that is operable between a cycling condition and a reclined condition in which the seat forms a bed. The cycle may also include a collapsible shelter that, when erected, encloses the tricycle.

A scooter seat device, in particular, a kick scooter seat device, with a seat base body and with at least one first fastening unit for fastening to a scooter. The first fastening unit comprises at least one support surface, which in a mounted state is provided to support the seat base body at least against a footboard of the scooter.

An adjustable rear wheel hood system has a movable hood, so to be longitudinally adjusted to accommodate shrinking wheels (due to wear), or other requirements. A longitudinal slot is aligned between the rear wheel hood and the deck, and after adjusting the hood-to-rear wheel separation to a desired amount, the hood is secured to the deck. Either the deck or hood is configured with the slot, while the other piece has holes and/or alignment features that align the pieces together, provide a way to secure the pieces together, and also prevent lateral movement of the hood. A similarly configured adjustable non-braking rear hood is described.

A school children rescue vehicle is provided. The vehicle includes an electric mobility scooter assembly. The vehicle includes a protective shell configured to attach to the assembly. The protective shell includes a plurality of hardened flat panels configured to connect between themselves and form an overall 5-sided shaped enclosure and arranged to fit on top of and connect to the electric mobility scooter assembly and structured to provide projectile protection for personnel situated within the protective shell. The shell includes a plurality of viewing ports of bullet proof glass positionable within the hardened flat panels and configured to provide line of sight viewing for personnel inside the protective shell. The overall external dimensions of the protective shell are such that the vehicle can maneuver within tight enclosed spaces. The vehicle functions as a deterrent to school violence and as a rescue vehicle for an active shooter situation.

A foldable scooter comprises a front wheel unit, a frame unit, a rear wheel unit, and a. seat unit. The frame unit comprises a connecting rod, a linking rod, and a stand, wherein the stand comprises a footboard, a chassis, and two side cover plates located on two sides of the footboard, the linking rod is located in a space between the footboard and the chassis, the connecting rod has an end fixedly connected with the front wheel unit and an end stretching into the middle of the footboard from front to be fixedly connected with the front end of the linking rod, and the rear end of the linking rod is fixedly connected with the rear wheel unit. The foldable scooter is simple in structure, convenient to operate, and capable of being folded to he stored and transported easily.
