Michael, >but I want to make mine a trike. Sorry, Jurges. :-) good idea, especially for winter. A python trike should be more stable than a flevo or airbike trike. And if you make the rear part exchangeable with a normal rear part than you can easily have both, bike and trike version. In all cases this will be a new candidate for my modifications page. Good Luck! >Now, Here's the truth. >We all want to build a vehicle as inexpensively as possible. >Get yourself a couple of bikes that no one wants and follow as closely as >you can what the folks on this group have done. >BUILD THE DAMN BIKE! >Don't plan it to death. 100 percent agreement. It is good that someone dares to say this clearly. A lot of people tend to make too much plans before they start building or even worse they get stuck in this planning phase before having touched a single piece of metal. Best Regards, Jürgen.
