So when is a bike not a bike?

When I was in at Grafham Water cycle shop today a guy came in and asked if a mechanic could help him with brake problems on his bike, Viv said, sure thing bring it in.

Well our jaws dropped when he brought his Elliptigo into the shop with a trailer attached. So is it a BIKE?

An example -

I asked where he was from, he said that he was from West London on his way to Lincoln and could we give him help with directions!!

They have a similar relationship to 'bikes' as 'indoor fireworks' do to the real thing.
