It sounds like a passive-aggressive scheme to have you buy your bicycle from their shop exclusively which limits your potential to find the best bike for you, not the best bike they can offer you

When I was bike shopping (although I had the idea that I would get it that day and then take it up North with me...bad idea but oh well), I got to ride anything I wanted for free and that's the way it should be! They may ask you for your license or something while you're out on the bike to prevent you from stealing it but you shouldn't be financially tied to their shop if you haven't even been on a bike
