A front fork includes a spring that is provided between a first cylindrical body and a second cylindrical body and applies a force in a direction to separate the first cylindrical body and the second cylindrical body, and a spring seat portion that is provided on an outer peripheral surface of the first cylindrical body and receives a first end of the spring. The spring seat portion includes a fixing portion that is fixed to the first cylindrical body, a spring seat body that is made of metal and receives the spring, and a third cylindrical body that is disposed between an inner peripheral surface of the spring seat body and the outer peripheral surface of the first cylindrical body and reduces a frictional force when the spring seat body rotates.

Brake calipers and rotors for bicycles are described herein. An example brake caliper includes an outboard caliper portion to be disposed inboard of a frame of the bicycle. The outboard caliper portion includes an outboard caliper body and an outboard brake pad that is fixed relative to the outboard caliper body. The brake caliper also includes an inboard caliper portion coupled to the outboard caliper body. The inboard caliper portion is disposed inboard of the outboard caliper portion when the brake caliper is coupled to the bicycle. The inboard caliper portion includes an inboard caliper body and an inboard brake pad that is movable relative to the inboard caliper body.

A micromobility transit vehicle may include a steering assembly. The steering assembly may include a fork, a steer tube, a stiffening brace, and a stem. The steer tube may extend from the fork and be positioned to rotate within a headtube. The stiffening brace may extend from the fork and be positioned about the headtube. The stiffening brace may include a first engagement surface. The stem may be coupled to the steer tube and the stiffening brace to secure the steering assembly to the headtube. The stem may include a second engagement surface complementary to the first engagement surface and engaged with the first engagement surface to rotationally lock the stem and stiffening brace together.

Disclosed is a personal mobility device including a towing module configured to allow various types of towed modules to be selectively connected and towed, and a connection device configured to connect the towing module and the towed modules. The connection device includes a connection member extending rearward from the towing module, a connection shaft having an upper side rotatably supported on the connection member and a lower side coupled to a shaft coupling hole formed on a connection frame of the towed module, and a locking device provided on the connection frame to lock the connection shaft.

A scooter includes a frame which has a footboard and supports a rear wheel, a steering column provided with a front wheel pivotably mounted on the frame, and a motor provided with a drive shaft coupled to the rear wheel via a transmission system. The transmission system includes a rear transverse shaft having a first end portion and a second end portion rotatably coupled to the rear wheel; —a gear system having a sprocket coupled rotatably to the first end portion and in meshing engagement with a toothed gear rotatably coupled to the drive shaft; and—a rear structure attached to the frame, supporting the gear system and the rear transverse shaft, and extending laterally along one side only—right or left—of the rear wheel, such that the second end portion extends from the rear structure to support the rear wheel in a cantilevered fashion.
