Throttle is not working on my bike, but pedal assist is functioning.

Introduction

If you're experiencing an issue where your Magnum Bikes e-bike's throttle is not working but the pedal assist function operates correctly, this guide will help you understand and resolve the problem efficiently. At Magnum Bikes, we are committed to ensuring you Ride Longer, Ride Farther, and Ride Faster with confidence.

Issue Description

When the throttle on your electric bike fails to respond while the pedal assist continues to function, it usually indicates a specific throttle component issue rather than a system-wide failure.

Signs

• Throttle does not engage or power the motor when activated.
• Pedal assist activates the motor normally when pedaling.
• No error codes displayed on the VeloFox or Das-Kit LCD display related to motor or battery.

Recommended Solution: Throttle Inspection/Replacement

Based on our diagnosis, your bike's throttle component appears to be malfunctioning.  This can be caused by a throttle that is simply too close to other components, especially with thumb throttles.  Visually inspect your throttle and make sure it is not getting caught on another component on the handlebar, like a shifter or bell.  It can be necessary to loosen the throttle clamp bolt or screw and slide it away so it can function freely.  If your throttle seems to engage without getting stuck on another component, inspect the throttle cable and pins (unplug from display/cable tree).  If any pins are missing, bent, or damaged, a throttle replacement is suggested.  It can also be necessary to replace the component the throttle plugs into, usually the display or cable tree.  Visually inspect the adjacent cables and plugs and make sure no holes are crimped shut, or pins bent.  IMPORTANT: If one of your electrical connections is damaged, don't plug it into another component, or you risk spreading the damage to good components.  

What to Expect

If you were shipped a new throttle, cable tree, or other component, you can either visit one of our authorized dealers for professional installation or follow the "Throttle Replacement How-To Guide" available in our Help Center for step-by-step instructions. 

Safety Reminder

Handling electrical components requires caution. If you are unsure about the installation process, we strongly recommend professional assistance at one of our flagship stores or authorized dealers.
