It would be much faster if I got the aerodynamics right, but on this first build, I did get the ergonomics correct for my needs the first try. It s very comfortable to ride and easy to use, with plenty of storage space. It can also be brought through a doorway into an apartment.
From downhill testing, I was able to derive a CdA figure of 0.25 m^2, but commercial models exist that have less than 1/5th that amount of aerodynamic drag. With the first body I made for it shown in the above videos, it required approximately 500W of power to hold 30 mph on flat ground. I ve reached more than 50 mph downhill in it and it has proven stable while making a lane change at that speed over imperfect roads, and the mechanical braking system has proven adequate.
