Understanding Your Cowboy E-Bike
Cowboy bikes are built with smart, integrated technology — a torque sensor that measures your pedalling power, a controller that manages motor assistance, and a communication module that connects your bike to the app. Everything works seamlessly — until one component stops talking to the others.
When something feels off, it’s often caused by:
⚙️ Torque sensor issues — weak or inconsistent motor assistance.
🔋 Controller faults — bike won’t power on or shows “Motor Cable disconnect.”
📶 Comm module problems — Bluetooth or app connection failures.
🛞 Drive belt & brake wear — squeaking, slipping, or braking delay.
⚡ Motor or wiring errors — intermittent cutoffs or power loss.
At Cowboy Bike Service, we use official diagnostic tools to identify exactly where the issue lies — whether it’s electrical, mechanical, or firmware-related — and fix it using genuine Cowboy parts.
Percentage is based on numbers of cases we performed the services in the last 4 years!
Advanced (Motor assistance - Electronic parts replacment - Noices from the rear wheel - Brake bleeding - etc..)
Basic (Brake pads - tires - set up new bike - accessories add-on - parts greasing - etc..)
