This is a cargo bicycle made almost completely out of wood. [Niels] and three of his classmates built it at Wico Campus Tio, a science and technology school in Dorpsstraat, Belgium. There’s a lot to be impressed by in this build. Sure, the guys concede that not everything is wood. They used metal screws as well as hubs, a crank shaft, and gears from a bicycle (not seen in this image). But everything else was made from Beech or Padouk wood. This includes the leaf springs that help cushion the cargo box from the bumps in the road.
The box itself acts as the handlebars. You can see the bracket which holds one end of a dowel spanning the left side of the box. This image was taken before the seat and cranks were added, but once they’re in place the front axle will turn along with the box for steering.
You can get a good look at the finished bike in the video after the break. You’ll also find a link to the Power Point slides there. Since that presentation is in Dutch we translated the text and pasted it below.

Wood Award 2012-2013
- The idea came from the bike to another idea to an old moped or scooter again wood to build. This would cost too much time to go and then said someone from our group: ’z illing not we build bike? First, it would be a recumbent but this was a little too simple so we went for the challenge to a tricycle, almost entirely of wood to build.
- The wheels: These we entirely from wood, only the wooden rim, we work a metal hub of a bicycle wheel original.
- The crankshaft: The crankshaft is milled in the frame and then we work a crankshaft that we have cut from an old bike in our wood.
- The box: This is a simple style and line construction with panels in a panel groove. The panel gets a groove depth of 10mm. The panels are subsequently glued false styles for a better view.
- The springs: The springs we himself by beech slats of 7 millimeters thick on each gelijmt make it a leaf spring 50 millimeters thick will form. The leaf springs are 80 millimeters wide.
- Steamed beech
- Seat tube length: 0.68 cm
- Seat tube angle: 66-70 degrees
- Inner diameter bicycle rim
The rim word made up of 4 different segments. These are joined gedreveld, and around each segment become a groove machined where the outer ring of a real bike rim perfect size safes.
- First we make wooden slats 21x21mm
- It become a groove 7mm wide and 3mm deep milled
- Then there are small slats in paddouk glued to detail
- When the glue has dried, the spokes around sanded
- There will be a bicycle hub in a block glued
- This block is then in our hub hub glued
- Around this hub will the rest of the wheel made.
- Domino dowels as connection,
- In the corners on one side, we have the styles, but 40mm wide so that it is made with the thickness of the uprights to which they are nevertheless continue to 60mm,
- The stuurbar is screwed to the container,
Seat tube construction
- Sawn from beams with bandsaw.
- Put rampa fixed with nuts and bolts.
- 3 parts come with a pen paddouck.
- Block seatpost is glued and screwed.
