Contemporary designer builds a wooden Scrambler electric bike
Meet Electraplywood, a dashing wooden electric bike that combines classic motorcycle looks and durable design in one pot. The electric bike is made almost entirely from plywood (hence the name) and can reach a top speed of 45 km / h, according to an email sent to IE.
The sustainable project of a contemporary cabinetmaker
The inspiration for the all-electric bike arose from designer Evie Bee’s passion for vintage cafe racer and scrambler motorcycles and her desire to salute and keep these iconic elements alive through her modern interpretation. As a conscious cabinetmaker, Bee strives to combine sustainable design, modern manufacturing methods and traditional building techniques in his works.
On its website, Bee further explains that “[she] felt that this project would be a perfect and stimulating opportunity to bring all of these interests together and push my manufacturing skills to the limit. One of the other factors that motivated me to choose to make this bike was the desire to fulfill my dream of owning and riding my own electric bike. “
Building the Electraplywood
After researching through various scrambler motorcycles, Bee decided to model his own after the Yamaha SR 250 Scrambler, as it is one of the most popular motorcycles for custom scrambler motorcycle projects.
With layers of durable poplar plywood, which were milled on a CNC machine and steel parts cut on a plasma cutter, the project began to take shape. Including its battery and motor, the bike weighs around 66 lbs (30 kg), roughly the same weight as e-bikes with big tires which typically range from 55 to 77 lbs (25/35 kg). To reduce the weight, poplar plywood was used for the center frame, Bee told IE.
For added strength, birch plywood is used for the outer frame parts and the legs are made of stainless steel. While not a delicate piece of work, it is certainly designed to be sturdy. As for the motor, Bee used a 26 “smart pie front wheel motor and Yose 36v 12.5ah battery.
Ingenious solutions in the manufacture of the bicycle
One of the frequently asked questions by Evie was why she ddoes not hide the battery. To which she replied: “The design of the bike is inspired by scrambler motorcycles, whose fuel tanks are very visible. I wanted to fit this into my own design, but swap the gas tank for a battery! “
She had to use V-brakes for her bike as the forks were salvaged from an old jump bike that was unable to accept new disc brakes. Regarding his bike’s brake system, Bee told Interesting Engineering that “the front brake is electronically wired into the motor, which means when the brake is pressed, the motor shuts down accordingly. It’s a good solution at the moment, but the forks should definitely be the first thing I upgrade once I have the cash. ”She also said she was aware that this would be a necessity when the design would be marketed, and added: “The rear wheel is also equipped with a coaster brake, so there is additional safety.”
Evie Bee is currently working on a Kickstarter campaign for the Electraplywood, and you can submit your email if you’d like to be notified when the bike becomes available. And if you were as charmed as we were by the process, why not give yourself a try at building a DIY wooden electric bicycle with the informative booklets on its website?
