Hello Dustin,
My guess is that the pivot angle should be choosen large, e.g. 70 or
more degrees, to prevent the weight at the rear to influence the
steering behaviour.
I do not think that the trail matters so much as the angle, and you
probably can get away with taking a trail similar to existing
projects.
So if you go flevo style, a positive trail of 9cm(?), then you will
need
a steering damper to keep the front part upright. If you want a
negative
trail (-14cm all up to -28cm), you won't need that as the bike will
keep
itself upright as you sit on it.
good luck with your project! I'de love to get my girlfriend on a
B2B-tandem!!
best regards,
Dirk

Hello,
I am in the process of building a Flevo Back to Back and am wondering
if anyone could offer any wisdom. Pivot angle, Trail, etc.
My wife and I have toured Canada on a MIC WIC delta tandem twice and
have since sold the bike and I am going to build a dual drive train
B2B for 2008.
Any advice would be most appreciated.
Thanks.
