Yeah, never let them test drive it. You can ride it for them around a parking lot, shifting through all the gears and what not. But never let them test ride it. You never know if they had any experience on a bike. Most people that have never own a bike ususally tells you that they have own one and they can handle it. But most likely its all bullshit. If they insist on riding it, make sure they give you the money up front as collateral. But most people that buy bikes should know that no one ever give test rides. And yes "CASH ONLY" and if possible have one of those "conterfit pens" to mark the bills. I was out a bill one time because one of them was conterfit. So check the bills.
