"In September 2006, the Expertise Centre of Movement Technology of the Hague University started an extended research on the physical results of riding a Trikke. The research aims to discover which muscles are used and how many calories are burned while riding. In short a Trikke ride can burn up to 1000 kcal per hour, when riding at 20 km/h. Riding at an easy 15 km/h will still burn around 520 kcal; in comparison light jogging burns a little under 350 kcal."
