2-PIN MOTOR CUT-OFF FUNCTION
The 2-pin wiring helps send a brake cut-off signal when the lever is pulled.
On compatible e-bike systems, this helps interrupt motor power during braking for better control and safer riding.
IPX7 WATERPROOF DESIGN
The fully sealed structure helps protect the internal electronic switch from rain, splashes, and dust.
IPX7 waterproof protection makes this brake lever suitable for common outdoor riding conditions.

It is suitable for daily commuting, replacement service, and compatible e-bike brake setups.
