Catrike Pocket Coroplast Velomobile V2
Made some major design changes in this shell. Most notably is that I have chosen to forego the PVC skeleton this time in an effort to save weight and make more aesthetically pleasing seams. I have also decided to go with a wheels-in design to combat the cold midwest temperatures and also decrease aerodynamic drag. I have also increased the ground clearance slightly to be able to clear light snow. Mechanically there have been some changes as well. I have decided to stick with the wheelbase extension kit to increase stability, but I re-installed the 20" rear (drive) wheel that came with the trike, which has an 11-36 9-speed cassette with a SRAM X7 rear derailleur. The reason for this is the 20" wheel maintains the correct headtube angles for stable handling. When moving up the the 26", the front end dips down, changing the angle of the headtubes to be much too steep (not enough positive caster) which leads to extremely twitchy and unstable handling.
