Flat Tire? Keep Your Scooter Rolling

The most common cause of a flat tire is riding with incorrect pressure. Most electric scooters require at least 3.5 bar, so check your tire pressure weekly. Riding under-inflated or over-inflated can lead to:

• Inner tube damage and punctures
• Accelerated tire wear
• Poor grip and higher slip risk
• Longer braking distances
• Reduced handling performance

Easy Inflation Solutions

Accessing e-scooter valves can be tricky. A valve extender and a portable pump make inflation quick and hassle-free.

Professional Installation

Incorrect inner tube installation can cause:

• Motor cable damage
• Rim cuts
• Tire damage and reduced tube life

For best results and a long-lasting repair, consider professional installation.
