Long Andre

Context

 * Long-André: description en français Werkstatt Lastenrad's wiki page being built in parallel to this, contains most of what you can't find here.
 * cargo bikes overview, a "longjohn"-type cargo bike
 * has 2 wheels (1st column) and the load is placed in front of the rider, as low as possible, with the front wheel further forward
 * all types of load are known to have been successfully transported with longjohns (therefore there is one longjohn icon in each not-empty cell of the 1st column)
 * longjohns are probably the most common type of cargo bikes
 * they are described and discussed at the following pages: en.wikipedia, de.wikipedia, longjohn.org
 * they tend to benefit from the following advantages:
 * low center of gravity
 * good handling and moderate weight
 * moderate length and especially width
 * load is easily visible by rider
 * transmission is the same as for a normal bicycle
 * they may suffer from the following drawbacks:
 * steering is achieved through a mechanism that adds complexity (and price) compared to cargo bikes types such as long tail
 * load size is somehow limited
 * load weight is limited compared to vehicles with 3 wheels or more (due to resistance and also to the lack of inherent stability)
 * Werkstatt Lastenrad is a German organization (and they have a "product" called Long André):
 * "Knowledge common around the subject of DIY cargo bikes"
 * these pages may be partially translated at some point: FAQ, What it's about
 * André Frieboese, a member from Berlin, is the Long André's father (you can see him on pictures, he has long sideburns)
 * This is not a typical Hackerspace project, but more a typical project for the very young UCmakerspace.

Description

 * Building a long john-type cargo bike according to these (links from werkstatt-lastenrad.de):
 * illustration-rich "A6 cards" PDF document (German)
 * original construction manual (German)
 * French description, translation ongoing (content is roughly that of the "A6 cards" PDF document)
 * Making roadworthy vehicles is delicate enough not to improvise too much at first. Hence, this project is currently being led in a spirit of carefully following existing documentation.
 * The first thing to build is not the bike itself but a BikeBench (see below under Components). A BikeBench (this wiki's page) is a jig / workbench for bicycle-based creations, designed and implemented by Thomas Viebach from Werkstatt Lastenrad.

Goal

 * make a 1st working prototype of a Long André
 * organize Long André manufacturing workshops

Obstacles

 * documentation must be translated first (pending)
