The booking online was straightforward as was finding the office in central Prague. We booked a group tour but there were actually only two of us. Following a short tram ride to Brevnov (tickets there and back provided by our guide), we were given a short demo (riding the segway is surprisingly easy, whist at first I thought there was no way that I could do it, you start feed quite comfortable riding it within 5 minutes). We loved the route, staying away from busy places and letting us see a different side of Prague (leafier, more residential; Strahov stadium, parks and some great views of the city). Our tour took just over a couple of hours, with our guide providing interesting commentary at key points. While the company provided a tram ticket for return to the centre, we actually decided to get off by the Prague Castle from which it is a short walk to all the main sites. We would definitely recommend this if you want to try Segways in a relatively quiet place and if you want to see more of "ordinary" Prague away from the main sites.
