I am a road cyclist but want to buy a couple of hybrid bikes for my wife and I to take our two young children out on seats on the back.

I am looking at the Corratec X-Vert at Chain Reaction Cycles.

I am 6ft tall and ride a 58/59 road bike. Is a 54cm the right size for me?

My wife is just under 5ft 2in. Is a 45cm the right size for her?
