A braking system for a rollator with a frame includes an adjustable handle to be installed on a right subframe or a left subframe of the frame of the rollator, a bracket fixedly connected to the handle, a lever rotatably connected to the bracket, a lock movably connected to the bracket and configured to fix the lever in a locked position when the lock is moved relative to the bracket once the lever is rotated toward the frame, and a wire operably connected between the lever and a brake on the frame of the rollator, such that the wire applies the brake when the lever is rotated toward the bracket and when the lever is fixed in the locked position.

A bicycle braking system includes a lever assembly, a parking brake mechanism, and a positioning assembly. The lever assembly includes a housing and a brake lever pivotably disposed on the housing. The housing has a first positioning structure, and the brake lever has an engagement portion. The parking brake mechanism includes a control handle pivotably disposed on the housing so as to be engaged or disengaged with the engagement portion. The positioning assembly includes a positioning handle pivotably disposed on the control handle and having a locked position and an unlocked position. when the positioning handle is in the locked position, the positioning handle is positioned at the first positioning structure so as to stop the control handle from be pivoted with respect to the housing. When the positioning handle is in the unlocked position, the positioning handle is removed from the first positioning structure.

The disclosure provides a bicycle braking system including a lever assembly, a parking brake mechanism, and a positioning assembly.

The parking brake mechanism includes a control handle pivotably disposed on the housing so as to be engaged or disengaged with the engagement portion. The positioning assembly includes a positioning handle pivotably disposed on the control handle and having a locked position and an unlocked position. when the positioning handle is in the locked position, the positioning handle is positioned at the first positioning structure so as to stop the control handle from be pivoted with respect to the housing. When the positioning handle is in the unlocked position, the positioning handle is removed from the first positioning structure.

The disclosed method may include configuring one or more brakes based on a braking-related attribute expected at a geographic location being traversed by a personal mobility vehicle. By configuring the application of brakes of a personal mobility vehicle based on terrain, environmental conditions, and other geographic features, the system may reduce the risk of the vehicle skidding or tipping due to over-braking. In some embodiments, a rider may use a single brake lever to indicate a desire to brake and the system may make determinations about how to apply a combination of mechanical and electrical brakes to front and back wheels based at least in part on the location of the personal mobility vehicle. By configuring brake engagement based on a combination of controls and map data, the system may improve user experience and user safety, especially for inexperienced riders.
