A disc brake rotor comprises a hub engagement member, an outer member, and a coupling arm. The hub engagement member is configured to engage with a hub assembly. The outer member is provided radially outwardly of the hub engagement member with respect to a rotational axis of the disc brake rotor. The coupling arm extends radially outwardly from the hub engagement member to the outer member. The coupling arm includes a first axial surface provided on a first axial side in an axial direction with respect to the rotational axis and a second axial surface provided on a second axial side reverse to the first axial side in the axial direction. At least one of the first axial surface and the second axial surface is non-parallel to a reference plane perpendicular to the rotational axis as viewed in a radial direction with respect to the rotational axis.

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 hydraulic braking device includes an engaging base, a hydraulic brake, and a locking device. The hydraulic brake is provided on the engaging base. The locking device is adapted to fix the engaging base on a suspension fork of a bicycle, and includes a bolt and a handle, wherein the bolt passes through the engaging base to be screwed into a tapped hole of the suspension fork. The handle has a cam-shaped head pivotally connected to the bolt, and is pivotable between a first position and a second position. When the handle is located at the first position, the head presses against the engaging base to fix the engaging base on the suspension fork. When the handle is located at the second position, the engaging base is no longer being pressed against by the head, whereby the engaging base is movable relative to the suspension fork.

Embodiments of the present invention describe a recreational vehicle spindle, including a spindle body having one or more sockets in the spindle body, and an upper attachment mechanism in contact with the spindle body and adapted to attach to a steering component. The spindle also includes a lower attachment mechanism in contact with the spindle body and adapted to attach to a ski or wheel. The one or more sockets are adapted to each receive a ball and stud forming one or more ball joints.

A brake rotor has a circumferential brake track disposed about an axis of rotation of the brake rotor. The rotor has an outer peripheral edge circumferentially around the brake rotor. The rotor has two surfaces that face axially outward away from one another and that are on axially opposed sides of the brake rotor. The two surfaces define a thickness therebetween. The rotor has an edge surface facing radially outward on the outer peripheral edge. The rotor has a transition between each of the two surfaces and the edge surface. At least a portion of the edge surface is not perpendicular to the two surfaces in an axial direction.

A leaning vehicle has a frame, a straddle seat, a motor, a shock tower pivotally connected the frame, the frame being pivotable relative to the shock tower, and front left and right suspension assemblies connected the frame. Each of the front left and right suspension assemblies comprises a leg operatively connected to a corresponding front left or right ground engaging member and being rotatable about a steering axis, an upper suspension arm having a first end pivotally connected to the frame and a second end pivotally connected to the leg, a lower suspension arm having a first end pivotally connected to the frame and a second end pivotally connected to the leg and a shock absorber having an upper end connected to the shock tower and a lower end connected to the lower suspension arm and a brake assembly connected to the frame and the shock tower.

A power meter for a bicycle includes a body having a torque input section and a torque output section, the body configured to transmit power between the torque input section and the torque output section. The power meter also includes a printed circuit board (“PCB”) having a substrate and at least one strain measurement device which may be attached to the PCB.
