There is nooooo way I would ever consider dating someone who didn't have the same passion as I did for bikes. It's too big a part of my life - particularly if you like going to bike meets at weekends, rock concerts and camping out with just you and your mate and bike for company. I see a lot of very happy couples where the wife/gf is on the bike of the bike or has her own. You share the experiences and friends and life of biking ..... you show me a solid partnership.
This is a biking forum that I came across, too ....) its predominantly American and predominantly harley-owners, etc but there are lots of lovely ladies on there, too with their own bikes or just looking for love with bikers ...... and it's free, too!!
