Various powered mobility systems, such as scooters and wheeled boards, are disclosed. The powered mobility system can be a drive assembly, which can include a motor, transmission assembly, driving wheel, and power supply. The drive assembly can be detachable from the rest of the personal mobility vehicle.

A disc brake caliper and the body of an ABS system are mounted on a fork arm of a bicycle by means of a single adapter support that can be removably connected to the fork arm, and configured to removably support both the caliper body of the disc brake and the ABS system.

A saddle riding type vehicle having a front fork that supports a front wheel, a head pipe that rotationally movably supports the front fork, a down frame extending downward from the head pipe, a front wheel brake supported by the front fork, to brake the front wheel, a braking force adjustment device that controls braking force of the front wheel brake, and output piping that connects the braking force adjustment device and the front wheel brake, the output piping has metal piping extending forward from the braking force adjustment device disposed behind the down frame, flexible piping, and a connecting member that connects the metal piping and the flexible piping. The connecting member is disposed in front of the down frame, and the flexible piping extends forward from the connecting member, to be connected to the front wheel brake.

A balanced motorcycle powertrain is described. Embodiments of the balanced motorcycle powertrain include components mounted to a frame of a motorcycle such that the powertrain can be evenly balanced about a centerline of the frame. The balanced motorcycle powertrain can include, but is not limited to, a motor, a transmission, a pair of clutches, a clutch shaft, a crank shaft, a pair of superchargers, a pair of chains, a pair of rear sprockets, and a rear wheel. Each of the components can be oriented such that the powertrain is substantially balanced about the centerline of the frame.

A safety brake system is provided. The safety brake system includes a frame configured to be mounted to a vehicle above a vehicles tire; at least one sliding arm slidably coupled to the frame; and at least one actuator, wherein the actuator deploys the sliding arm to extend out of the frame and engage a driving surface in a braking position, and the actuator retracts the sliding arm to retract back within the frame in a driving position.

In human-powered vehicles, e.g., bicycles, etc., it is customary to use drum brakes, disc brakes or shoe brakes. Each of the braking systems has different advantages in terms of braking effect, system costs, ease of maintenance, etc. A brake unit with a modified structure for a vehicle is provided. For this purpose, a brake unit 14 for a vehicle 1 is disclosed, having a housing 15, having a brake body device 23, wherein the brake body device 23 supports a stationary brake partner of a brake apparatus 12 for the vehicle 1, wherein the housing 15 and/or the brake body device 23 defines a main axis H, having an actuator for moving the brake body device relative to the housing 15 in order to generate a braking force, wherein the stationary brake partner is formed as a brake disc 13.

A position of a center of gravity of a vehicle body is easily optimized. An ABS modulator is disposed in a vicinity of a pivot bracket, which is joined to a lower rear portion of a main frame, and to which a swing arm is swingably connected.
