The monty of Olaf uses an internal hub gear (3 gear) with back-pedaling-brakes.
http://www.olafjohansson.com/monty/montypage.htmlThe internal gears or brakes are no problem. I have ridden the monty in traffic in Malmö (a bigger city in Sweden), and found it a little dangerous because of the missing "real brakes". The back-pedaling-brakes do slow down the reaction time, or alternatively severily limit braking force when the pedals aren't in the right position. This is not a specific python problem, and probably the same on an upright.

Hello, does anybody have ever tried to build a python with an internal hub gear ( f.ex. i-motion 9...)and back-pedaling-brakes? i thought it would be a nice way to avoid some problems with the chain lenght. i know they are a little heavier then "normal" gears but it seems to me that the advantages prevails. or is it impossible because of stearing? i never had the oportunity to ride a python so i don´t know if its possible.
