The other of the first and second bicycle control components is attached to the second mounting bracket. The second mounting bracket is displaced between alternative attachment positions on the first mounting bracket. The first mounting bracket is rotated between alternative mounting positions on the handlebar. | 10-20-2011 |
| 20110247448 | Bicycle Suspension System - A mounting device is shown for mounting components to a bicycle handlebar having a handlebar axis. The mounting device includes a mounting bracket mountable to the handlebar about the handlebar axis. The mounting bracket includes a first clamp portion and a second clamp portion hingedly connected to the first clamp portion to interiorly receive the handlebar. An interior channel is defined by spaced sidewalls and formed in a portion of the circumferential length of one of the first and second clamp portions, and a hole is formed through the clamp portion and opens to the channel. | 10-13-2011 |
| 20110079945 | Spring Suspension for a Handlebar-Steered Vehicle - A coil spring suspension designed for a handlebar-steered vehicle. The coil spring suspension generally includes a first tube, a coil spring, a shaft and a guide. A first end of the coil spring is disposed within the first tube and fixedly supported proximate a first end of the first tube. The coil spring extends beyond a second end of the first tube. The shaft fixedly supports a second end of the coil spring. The shaft and the first tube are slidably displaced relative to each other upon suspension loading to lengthwise compress the coil spring. The guide is disposed within the first tube and connected to the coil spring between the first and second ends of the coil spring. The guide is displaced with the coil spring under suspension loading and limiting lateral displacement of the coil spring. | 04-07-2011 |
| 20110048161 | Control Cable Actuation Device - A control cable actuation device designed to be attached to a handlebar-steered vehicle frame member for a cable assembly including a control cable slidably disposed within a control cable housing. The actuation device includes a cable adjuster attachable to the frame member and an actuation lever configured to displace one end of the control cable. The cable adjuster is configured to receive the control cable and to axially displace to slidably displace the cable within the cable housing under cable adjustment. The lever is rotatably attached to the cable adjuster about a first axis to slidably displace the cable within the cable housing under cable actuation. The lever is also configured to rotate about a second axis to axially displace the cable adjuster to slidably displace the cable within the cable housing under cable adjustment. | 03-03-2011 |
| 20100170731 | Drive System for Driving a Vehicle Wheel - A drive system driving a vehicle wheel at various speeds. The drive system generally includes a transmission assembly configured to drive the vehicle wheel in a forward direction and a motor rotatable in a first direction and a second direction and configured to drive the transmission assembly. The transmission assembly is configured to operate in a first operating mode when the motor is rotating in the first direction to provide at least one first wheel speed in the forward direction. The transmission assembly is configured to operate in a second operating mode when the motor is rotating in the second direction to provide at least one second wheel speed in the forward direction. | 07-08-2010 |
| 20100083788 | Bicycle Control Device - A bicycle control device includes a lever for actuating a brake control mechanism and a shift control mechanism in a cable-release direction and a cable-pull direction.
