What it is and how it works

Designed to engage automatically for improved grip, the Lock-Right provides a controlled, torque-sharing action between rear wheels.

Real-world use cases

Imagine navigating slick pavement, gravel, or uneven surfaces with more confidence as one wheel can gain extra bite when needed.
