[From Graham Butler March 15, 2011 Input from Bill Warner and a mechanical engineer in at a Cambridge rotary compressor company who suggested the "deadman switch" idea like on a chain saw.]
I just got back from Brazil at the end of last week, things got hectic the last couple of weeks before leaving.
I think that the last we left the design, we had talked about a 'deadman's switch' for the brake release. It makes sense. Check out the attached screen shots of my first hash. It is very simple.
Talked to Seth today. We are getting material ordered so that he can build front forks. I figured that while some aspects of seating might change, it is very unlikely that the front fork geometry would change substantially.
