30? still in nappies then......
I'm 72, been into vintage/post vintage bikes since I was 16, still got one I bought in 1967, but then I'm odd any, why? its indefineable, something about ancient mechanics is fascinating.
just don’t know how fast/slow they are.
They are just slow, a modern 125 will see most of them off.
How they behave.
They don't they misbehave, live with it. travel with tools and spare cables and plug, and the phone numbe rof a recovery service.
They are a steep learning curve, you need to learn to ride a whole new way, don't even think about keeping up with modern traffic, just let it go past you, you'll catch it all up soon enough.
To sum up, I have a bike from the 1920s, another from the 1930s, and one from 1950s I would not trade any of them for a brand new modern bike.
