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 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)

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 (this wiki's page) is a jig / workbench for bicycle-based creations, designed and implemented by Thomas Viebach from Werkstatt Lastenrad.

Outils requis:

• post à souder (conseillé MAG)
• scie à métaux ou meuleuse d'angle
• perceuse
• perceuse à colonne
• tarauds M8 et M10
• étaux à angle ou des étaux à cadre (Winkel- oder Rahmen-Zwingen)
• protections oculaires, lime, compas, pointeau, marteau, ...

Matière pour 3 BikeBenches:

• 2x 6 m de profil carré 40 x 40 x 3 mm
• 6 m de profil carré 45 x 45 x 2 mm
• 42 vis six pans M8 x 20 mm
• 42 écrous M8 à souder
• 3 vis six pans M10 x 25 mm
• 3 écrous M8 à souder
• 3 morceaux de tôle 40 x 40 x 3 mm
• 3 axe de roue avant + écrous correspondants
• 3 axe de roue arrière + écrous correspondants
• 0,6 m de tube rond 12 x 1 mm
