I'm thinking of getting a On-One Inbred. Nice bike and nice price. Anyway, they are sold out of 18inch frames, so should I bother getting a 16inch frame?

I quite like a bike that I can throw around etc and the smaller size does appeal, but I dont know enough to want to risk £400 on a bike could be small enough to lend to toddlers. Any advice appreciated.

it might, just

i'm building up a 16" dmr switchback, and i'm 5'11" and the 400mm seatpost is only just long enough. looks cool with that much seatpost sticking out though:)

so, you might be better with the 18" on-one

Have a look at the size chart here (if you haven’t already). It’s down the page. It looks like 5'10 is the largest recommended for the 16".

Get an 18in 456 its the new Inbred.

I'm 5' 9'' and have a 16incher. I think you'd be cramped though might be OK with a 100mm stem instead of the 80

Thre wil be mopre 18s in soon won't there?

Either that or go for the TI one which is only £599 at the moment

I reckon it depends on a lot more than your height - i ride one 16" bike and one 17" bike, and I'm 6'. This is because I don't like a long bike - my back doesn't like the stretch - can't hack road bikes either!

I suppose it depends on leg/torso ratio, i think i have longer legs than average, which would also contribute to wanting a shorter frame.

I use a very long seatpost on the 16" bike!
