I currently have the following:
1/2 - tandem, steel
1 - touring bicycle, steel
1 - long distance bicycle, titanium
1 - racing bicycle, aluminum
1 - mtn bike, aluminum
1 - fixie, steel
1 - single speed, steel
1 - stepthrough, steel
And possibly some bits and pieces of other bicycles.
How many is that?
............ 7.5.
Not all of these are completely built up, but I think there are enough parts around to build them all.
So if I could only have five bicycle, I'd have to get rid of 2.5, and I really don't want to do that.
I would, however, like at least three more ... a folding bicycle, a recumbent, and an ordinary are on my list. That would round things out nicely.
