What Is The Difference Between Inflatable Tyres And Solid Polyurethane Tyres?

Inflatable tyres offer much better on-road & off-road performance (the bike is springy, and therefore, much more comfortable). “Basic” models with solid polyurethane wheels are only suitable for smooth paved surfaces. The Basic model is typically preferred by childcare centres, toy libraries  and customers for whom low maintenance is more important than a comfortable ride.
