ELEEK VM-01 CNC Machined Aluminum Brake Rotor Adapter

This is a reliable engineering solution for high-power electric bikes. It allows you to convert from a standard bicycle brake rotor mount (6-bolt) to a heavy-duty motorcycle standard (4-bolt).

The adapter is perfectly compatible with popular electric motors like QS205 (Hub Motor) and other hubs with an ISO bicycle mount. It is manufactured using high-precision CNC milling from solid aluminum, ensuring maximum rigidity, lightweight performance, and durability under extreme braking loads. A reinforced motorcycle-standard braking system means your safety at high speeds!
