Contents
Context
- 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 ("loads", "loads and kids", "kids", "advertisement", "selling", etc.) 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, André Frieboese, Long André]
- 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 "Werkstatt-Kärtchen zum Bau von Long André" (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)
Goal
- make a 1st working prototype of a Long André
- organize Long André manufacturing workshops
Obstacles
- documentation must be translated first (pending)
Component
- BOM & list of needed tools are the first things that will be translated
- Documentation has almost the status of a component...
BikeBench
A BikeBench is a jig / workbench for bicycle-based creations, designed and implemented by Thomas Viebach from Werkstatt Lastenrad.
Links:
- Werkstatt Lastenrad's wiki pages: original (German), French (translation ongoing)
- this wiki's page
Long-André: description en français
Schedule
- Opening: May 2015
- Ending: ?
Participants
- Léonard (Leader, UCmakerspace guest)
- Marc Wettstein (UCmakerspace boss)
- The Werkstatt Lastenrad people in Germany, with whom emails are being exchanged: Christophe Vaillant, André Frieböse, Tom Hansing, Thomas Viebach
