Flat Tire? Keep Your Scooter Running

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 with pressure that is too low or too high can cause:

• Inner tube damage and punctures
• Accelerated tire wear
• Poor grip and an increased risk of slipping
• Longer braking distances
• Reduced handling performance

Easy Inflation Solutions

Accessing e-scooter valves can be tricky. A valve extender and a portable pump allow for quick and easy inflation.

Professional Installation

Improper installation of the inner tube can cause:

• Damage to the motor cable
• Scratches on the rims
• Tire damage and a shortened inner tube lifespan

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