IMHO, if the lift attendants keeps asking you, you should try to promote the sport and tell him what you're riding really is and how he can learn about it. You can tell him what it can really do besides speed. I'm all about promoting the sport the best you can.
I hope I don't get flamed for this, The rest of the post have gone to technical board specs. If you're talking to a lift attendant or a random person in line you don't got the time to explain it to convince them enough to convert. Keep it short and simple to promote the sport, you only got a couple seconds sometime to promote the sport most of the time. Sometimes the bes tyou can do it point them in the right direction to do the research to get interested
