Explanation/Typical Example
22.2mm (the global standard for flat/riser handlebars used on most off-road e-bikes).
Usually Aluminum Alloy (for strength and weight) or Forged Aluminum (stronger). Clamp and lever body might use different types of alloy.
Typical examples: SM-2A, SM-3A, or other customized connector (must match the controller’s e-brake input).
Motor Cut-Off Sensor/Switch. Vital for a high-power bike (like the JECHAM 4700W) to instantaneously shut down the motor when the brake is squeezed. Specify Open/Closed Circuit type (often customized by controller).
Must specify Mechanical Disc Brake. Other types (e.g., V-brake, Caliper) are common but rarely used on powerful e-bikes..

| 杠杆杠杆比 (拉力比) | Leverage Ratio (Pull Ratio) | Short Pull (common for mechanical discs). The lever must match the calliper's required cable pull distance (typically ~7mm for short pull). This must NOT be long pull (like for linear pull/V-brakes). |
| 断电开关功能 (电摩专供) | Cut-Off Switch (e-bike specific) | Motor Cut-Off Sensor/Switch. Vital for a high-power bike (like the JECHAM 4700W) to instantaneously shut down the motor when the brake is squeezed. Specify Open/Closed Circuit type (often customized by controller). |
| 断电接头类型 | Cut-Off Connector Type | Typical examples: SM-2A, SM-3A, or other customized connector (must match the controller’s e-brake input). |
| 安装孔径 | Clamp Diameter | 22.2mm (the global standard for flat/riser handlebars used on most off-road e-bikes). |
| 杠杆开度 / 杠杆角度 | Lever Reach / Opening | Specifies the distance from the handlebar to the lever. Many high-end levers offer Adjustable Reach to fit different hand sizes. |
| 材质 (手柄与夹座) | Material (Lever & Clamp) | Usually Aluminum Alloy (for strength and weight) or Forged Aluminum (stronger). Clamp and lever body might use different types of alloy. |

| 手感 / 阻尼设计 | Lever Feel / Damping Design | Might refer to Bearing Pivots (for smoother operation) or features like Low-Friction Bushings. |
| 重量 | Weight | Typically listed per pair or per single lever (e.g., 180g - 250g per pair). |
| 适用手把直径 | Handlebar Type | Refers to being Flat Bar Compatible (distinct from drop bars for road bikes). |
| 颜色 / 表面处理 | Color / Finish | Typical: Black (Anodized/Powder Coated) or Silver. |
