Wooden E-bike – Natural and sustainable wooden electrical bicycle
The Berlin Company aceteam develops the first wooden e‐bike. The “Wooden E‐Bike” is an ambitious project by Matthias Broda, founder and CEO of aceteam Berlin. In cooperation with the Faculty of Wood Science and Technology of the Eberswalde University for Sustainable Development (HNEE) the idea became reality. Combining state of the art CNC‐technology and the full knowledge of wood material.
The wooden ebike‘s distinctive appearance is characterised by its wooden “fork” and eye-catching frame, which resembles the human eye. The first wooden ebike prototype debuted in 2014 to critical acclaim.
The wooden ebike is an ambitious project from aceteam GmbH to create an electrical bicycle using environmentally-friendly manufacturing processes. In cooperation with faculty from the Wood Science and Technology department of Eberswalde University for Sustainable Development (HNEE), they‘ve developed the first wooden ebike for production.
In addition to being a natural material, wood also retains CO2, whereas metal production requires eight times more energy input, leading to increased CO2 emissions. As a result, the wooden ebike has a significantly lower carbon footprint than a standard bicycle.
“we searched for a way to get a mostly CO2 neutrally electrical vehicle, with the traffic jam in every European city, we prefer bicycles, wood that grows binds CO2, and grows right in front of our cities, we decided for ash tree which is a long fibre wood, that allows a high elasticity for our frame (used for example parallel bars, hammer shaft), so the result was less energy, less CO2 for our environment, for a comparable ebike with an outstanding design.” – Aceteam Berlin
Besides ecological reasons, a production with CNC machinery is the most cost efficient way of production guaranteeing repeatability unlike manufacturing. This suits the purpose of a small mass production and can be still customized to meet individual demands. As a unique feature the price will be similar to an upper-class conventional bike and therefor affordable for a majority of customers. it was priced for its innovation with this 2014 Green Buddy Award and 2015 Green Product Award.
Aceteams goal was to create an electrical bicycle and build it in an environmental friendly way. In cooperation with the Faculty of Wood Science and Technology of the Eberswalde University for Sustainable Development (HNEE) the idea became reality. Combining CNC-technology and the knowledge of wood material, the first wooden E-Bike was developed. Wood is a natural material but it also binds CO2 while metal production requires an eight times higher energy input leading to increased CO2 emissions.
lightweight construction makes the wooden eBike competitive with standard Pedelecs. The 17kg light bike is made of laminated ash wood. Ash wood is especially qualified for the bike frame constructions due to its outstanding performance under torsion, impact, and other stresses applied during cycling. The 250W motor supports the cyclist to a maximum speed of 25km/h over a distance of approximately 60km
Get the right mix between, thickness of the wood, wood glue and flexibility of the wood. We had to construct a torsion machine to investigate in lot of Tests for the best composition of our frame construction. So we had first to destroy a lot of wood to get new safe frame. After that we had to check, how we can protect our frame and make it resistant against all kinds of weathers We had the chance to use a climate box of the university in Eberswalde. Here we could simulate 5 years in 5 Month and get the results of over 40 different paints, some of them were totally gone and other looked like the 2nd day.
“Science meets Sustainability the difficult war to choose right dimension between the thickness of Lamination and flexibility of the wood. what weans, thicker Lamination means lower flexibility and less weight, thinner Lamination means higher flexibility with higher weight. So we started to research the best combination of of weight and flexibility, so what we did is, that we built a torsion construction, that would be able to destroy the wood in a controlled way. It took us have a tree get the best performance for our wooden ebike.”
