It's 37lbs, which is 16.78kgs. Thanks for the advice on footrests. I used to have something like that on another bike, but I've just got through fixing two stems to the chain stays, which should work a treat. I'll post pics when I'm done. I might very well get two more, place them at the back, and try and fix a foot deck along it. I always thought the footrest (are they called snapdecks?) on the xtracycle looked really inviting.
