Just found this on the luego site.

Trike linky

Branching out?

Mmmmmmmm.............shobodywahwahhhhhhhh

saw that at harrogate show, very tidy in the flesh

Saw it in the Factory last week... Mmm Nice... Also looks good and sturdy.. A quality job... no less than what you would expect from Luego.. probably not cheap.. but then quality dont come cheap.

Looks like the principle could be applied to ANY shaft driven bike.
I suppose with a different Diff arangement it could be applied to any bike ie the chain driven ones as well.

Will have to get the wife to decide she wants one
