Cowboy Brakes Noisy or Weak?

Unusual noise or reduced braking power can affect safety and riding comfort.
In most cases, the issue is not just the brake pads and requires proper adjustment.

We identify the exact faulty component before replacing anything.

What This Usually Means

When your brakes become noisy or lose power, the issue is usually related to how the braking system is functioning — not just worn parts.

In most cases, it can be caused by:

• Uneven movement in the brake system

• Dirt buildup affecting performance

• Incorrect alignment between brake components

These issues often develop gradually and can reduce both braking performance and control.
Simply replacing parts does not always solve the problem.

How We Fix It

We fully service the braking system to restore proper function.
This includes cleaning, adjustment, and precise alignment to ensure consistent braking performance.

In some cases, additional work may be required depending on the condition of the system.

Common on Certain Systems

We see this issue more frequently on specific brake systems where dirt buildup can affect performance over time.
Regular maintenance is important to keep the brakes working correctly.

We restore full braking performance using the correct tools and methods.

The Components Behind Most Cowboy Issues

Most recurring problems are linked to one of these components.

Torque Sensor

The torque sensor measures how hard you push on the pedals and sends this information to the controller.
The controller then adjusts the motor assistance in real time to match your effort.

Controller

The controller acts as the brain of the bike.
It manages power delivery from the battery to the motor and processes signals from the sensors.

Comm Module

The communication module connects the bike to the Cowboy app via Bluetooth.
It handles firmware updates, connectivity and diagnostic communication.

Motor

The motor is located in the rear hub and provides electric assistance while you pedal.
It relies on data from the sensors and commands from the controller to operate correctly.
