This is a mechanical brake lever with an integrated motor cutoff sensor for e-bikes and electric scooters. When the lever is pulled, it sends a signal to cut power to the motor, which is a common safety requirement on many electric drive systems.
It’s used as a replacement lever on bikes or scooters that already use a 2-pin waterproof brake cutoff connection and standard flat handlebars.
Key Features
• Integrated motor cutoff sensor disables motor when braking
• Waterproof 2-pin electrical connector
• Aluminum lever body for durability
• Designed for left or right side use (single lever)
• Pre-installed sensor cable with connector
Compatibility & Use Notes
• Fits 22.2mm flat handlebars
• 2-pin male waterproof connector
• Approximate cable length: 13cm
• Compatible with many e-bike and e-scooter controllers that use 2-pin brake cutoff sensors
• Not compatible with hydraulic brake systems
• Not universal—connector type and pin orientation must match your controller
Service / Ownership Context
Brake cutoff connectors are not standardized across all e-bike brands. Connector shape, pin layout, and voltage expectations vary by system. Before installation, the existing connector should be visually matched and verified. Mechanical brake adjustment is still required after install to ensure proper braking performance.
Fit & Use Signals
• Good fit if your e-bike or scooter uses a 2-pin waterproof brake cutoff connector
• Good fit for replacing a damaged or broken cutoff lever
• Good fit for mechanical brake systems
• Not a fit for hydraulic brakes
• Not a fit if your controller uses a different connector style or pin configuration
