Hi All,
Long time since I have posted, but I do read with interest all the
Python developments.
Like some of you, I was somewhat mystified by the video of Dennis
Renner's new FWD RWS recumbent. So without any real specs to go on
other than the 17 degree pivot I decided to create a simulation. At
first I had no luck at all, and it just crashed and was completely
unstable, and I was really starting to think that it was impossible, but
perseverance has paid off, and I now have a working simulation of his
FWD RWS bike. What I can report is that the Centre of Gravity needs to
be biased towards the front with about 60-70% of the riders weight over
the front wheel. The pivot is also more stable, the closer the
intersection point is to the middle.
I imagine that you would probably need to sit more upright to balance
this bike, 30-40 degree seat angle rather than 20.
Kind Regards,
