Hi Dirk,
That's a really good idea I have not thought of before. I suppose converting
the coaster brake / free wheel single speed hubs to fixed gear would enable
pedaling in both direction, even in the delta configuration to go in reverse.
Running a handle stick to the back may be a little tricky: 1. not to limit
current steering angle, 2. not interfering w/ the front seat, so the handle
probably has to be underneath the futon, with a cable looping over the top...
However, would adding a handle would put the trike further from it's python's
hands-free origin? :) quoting Jürgen "Once you have learnt the steering
principle, the bike can easily be handled without using your hands, therefore
handlebars can be omitted." The trike form requires very little learning to
ride hands-free, minutes compared to months on a bike. In fact, python trike
riders don't know what to do with their hands when freed at first...
Confession, I have only invested 10 min in learning to ride my python bike (45
deg pivot, 30 deg seat, bad combo?), which rides nicely with 2 rear wheels
(swappable), so my excuse is to focus on social / cargo vehicles which requires
more wheels for loading and balance...
Vi

Hello Vi,
it would be cool, if you could reverse the driving direction in the case of two
riders, such that both of them sit in the back and the Futon Express in
balances
again. Steering could be done with a handle in between the two riders.
Reversing the pedal direction is probably not easy though...
regards,
DirkS
