When they train you, you will be on it zipping about in the start vicinity, not standing about for 10 or 20 mins while they talk and then hop on. At least that's how I was taught on one in Budapest and Dubrovnik.
It's literally just you have a go on a Segway? In a car park or a sports hall or something?
Please check it out. Not sure about the 30 minute, I thought this ad was for an hour. Your expert instructor will get you and your lucky guest fully up to speed with an introduction, safety briefing and dedicated training session before you harness the sleek speed of these electric steeds for yourselves and head out for an exhilarating blast around the awesome Segway Rally Course.
So you only get 10mins to ride if you opt for the 30mins? 20mins seems like such a long time for health and safety.
