Walking from Hackney to St Panc with a monster

An idea that could be researched whether its allowed on board is to go up to Hackney central overground and take the train to Caledonian rd then cycle it down to Kings Cross.....

Maybe but like splat said it prob wont fit (would have to dismantle) and those stairs WOULD be killer! + not daunted by the journey/ distance etc. Cheers though!
