Urtopia Carbon Classic Specs, Tire Pressure, & Size Guide
Complete specifications, PSI calculator, and tire size information
The Urtopia Carbon Classic features 700x40c tires with a recommended pressure range of 45-75 PSI. Proper tire inflation is critical for this e-bike's performance, safety, and battery efficiency. At 41 lbs, the bike's weight combined with your body weight and any cargo determines the optimal PSI for your specific riding conditions.
Running the correct tire pressure prevents pinch flats, improves handling, and maximizes your battery range. Too low and you risk damaging your rims on bumps; too high and you'll experience a harsh ride with reduced traction. Use our calculator and reference tables below to find your ideal pressure based on rider weight, terrain type, and cargo load.
