Various technologies for reducing a speed of land vehicle by rotating its handle bar. A device comprises: a handlebar having a longitudinal axis; a seat coupled to the handle bar; a line coupled to the seat; and a brake coupled to the line, wherein the handlebar is rotatable about the longitudinal axis such that the seat moves and thereby controls the brake via the line.

Provided herein is a training device configured to allow a user to simulate all of the balancing and turning movements of downhill snow skiing or snowboarding on dry, downhill surfaces. The device is equipped with a braking system that allows the user to slow down the speed of travel when the moving direction changes from forward to sideways, thereby simulating the act of slowing down on a slope by turning a ski or snowboard. The braking effect is further enhanced when the ski or snowboard is tilted towards the uphill direction, further simulating the actual movements of skiing or snowboarding on snow. The braking system may include one or more mechanisms to amplify the force applied to the brake cables. An optional steering bar may be provided with handles that are positioned ahead of the bar to simulate the planting of ski poles prior to or during a turn.

Various technologies for reducing or increasing a speed of a vehicle by rotating its handlebar.

An operating device for a human-powered vehicle includes a base member and an operating member. The base member includes a first end portion, a second end portion, a base body, and an accommodating structure. The first end portion is configured to be coupled to a handlebar. The second end portion is opposite to the first end portion. The base body is configured to accommodate at least one of a hydraulic unit. The accommodating structure is configured to accommodate at least one of circuitry accommodating part and a power-supply accommodating part. The operating member is pivotally coupled to the base member about a pivot axis. The accommodating structure is a separate member from the base body. The accommodating structure is detachably attached to the base body at the second end portion.

Various technologies for reducing or increasing a speed of a personal transportation vehicle by rotating its handlebar. Some technologies provide this functionality based on a stem, a rack, and a brake. Some technologies provide this functionality based on a worm gear, a stem, and a brake. Some technologies provide this functionality based on a cam, a cam follower, a rod, a stem, and a brake.

A driver assistance system 1 for a motorcycle is provided with: a driving force output device 82 that generates a backup output for reversing a drive wheel and backing up a vehicle body; a brake lever 810 squeezably operable by a rider; a ACC main switch 43 and an ACC lever 44 operable by the rider; and a back out assistance controller 64 that controls the driving force output device 82 on the basis of the operation of the lever 810, the switch 43, and the lever 44. The back out assistance controller 64, after causing the driving force output device 82 to generate the backup output when triggered by receiving an operation of turning the lever 44 to a SET/ side, continues to cause the backup output to be generated until the lever 810 is operated, or until the switch 43 or lever 44 is turned off.
