what i have found is that the 'fellowship of the bent' means most people on bents will stop and chat wherever you are;
I think we might have met Bob, I was in Hyde Park with my mate, (think this year, but maybe last) either on our ICE trikes or his Greenspeed Tandem. Chatted with a guy on his Kingcycle, who I'm pretty sure was called Bob (there may be a lot of Bobs , but suspect not too many own Kingcycles ! ) think you were off in search of a chain guard, so you could race it ?
There's definitely enough of us n or near London to make a ride worthwhile, was out on a ride last Sunday with "Auntie Helen" of this forum and my mate, so that was 3 ICE trikes, sure we could beat that number if we tried !
