I change into my orang-utan suit in the bowels of the Park Lane underground garage. They set the lights really low in there, so behind the Planet of the Apes rubber mask I can’t see very much, but take great pleasure from riding under the exit barrier, just.
Out in the sudden brightness I’m briefly in big traffic, then cross the pavement to ride straight out into Hyde Park and on what must be one of the widest and most luxurious bits of cycle path in London: the avenue of mature plane trees that runs adjacent to Park Avenue.
Three lads ride up alongside, they want to take my photo, and so I stop while bystander’s watch and chuckle. I’m just a guy dressed as a monkey riding an armchair bicycle.
