This is the "best" bike, a 2003 Longstaff custom built fixed wheel:
(I've fitted a nicer stem and bars since the photo was taken.)

This is the same bike (2005) , in its original colours:

This is the "proper" tourer, a Surly CrossCheck:

The same bike, in action:

This is the SS hack, originally a Ridgeback Meteor hybrid, but continually being changed.
(It now has swept back handlebars)

The same bike, an action.

And this, I think, is unique, a singlespeed, two wheel drive, 2007 Longstaff tricycle:
(It has nicer bars now.)

And loaded up:

(Apologies to everyone who just wanted clean, stripped down SS and fixed.
