My wife thinks I have gone a little overboard with this bike thing, if you have the same problem show her the roper coal and steam powered bike built back in 1892. Looks like some of us have been going overboard for a long while. The bike I am talking about went to auction this week and was exspected to bring seven figures, only two were made the other is in the "Smith". O by the way Mr. Roper died in a bike crash!
