Troubleshooting Your Electric Bicycle: A Comprehensive Guide

Electric bicycles, or e-bikes, offer the perfect blend of traditional cycling with a bit of motorized assistance, making eco-friendly commuting and leisurely rides more accessible than ever. However, like any machine, e-bikes can encounter issues. Here's a detailed guide to troubleshoot common problems you may face with your e-bike. 🛠️🚴‍♂️

Battery Issues 🔋

1. E-Bike Won't Turn On

Possible Causes:

• Loose Connections: Check all the battery connections and ensure they are secure.
• Battery Not Charged: Charge the battery completely before the first use.

Solutions:

1. Inspect Connections:
