Its has been a while since my last post. Chassis design still in progress. I really want to incorporate crash protection into the velomobile. Semi-monocoque with the seat being part of the load bearing structure seems logical. Other velomobiles (apart from the Rotovelo) have separate seats which offer no strength to the structure but are only used for the rider to sit on. When you consider that the seat weighs about 1kg it makes perfect sense for the seat to be integrated into the chassis or in fact become the chassis with suspension members hanging off it. There will be a rendering/picture to follow in the next few days.
