Zelo, The Improbable Wooden Trike

The earliest bicycles were made from wood. Nearly two centuries later, some garage tinkerers still turn to this most traditional of materials for their own creations, since welding one requires experience and tools beyond the reach of many. Resembling Gilligan’s Island props, the resulting bikes are both artistic and great fun, but not very practical for real use; often heavy, ill-fitting or lacking durability.

[Boris Beaulant’s] birch laminate Zelo, on the other hand, has cleaner lines than anything you’d see in an IKEA showroom. Not content with an ordinary two-wheeler, he’s tackled a three-wheeled recumbent trike, which requires even finer tolerances. Two months and over 1,300 miles later, the trike is still rolling strong through the French countryside, proving its mettle as legitimate transportation and not just a garage novelty. [Beaulant’s] build log (Google translation here) offers some insights into the development of this masterpiece, starting with prior woodworking projects (furniture, rolling toys and a children’s bike) and finding clever solutions to problems such as creating a mold of his own back for a custom-contoured seat.

E-bike Across Canada For $10

Justin Lemire-Elmore E-bike

[Justin Lemire-Elmore] spent one month riding his electric bike across Canada last summer. He made the journey from Vancouver to Halifax in 30 days using a mere $10 worth of electricity to recharge his bike. He put together a rather bizarre looking semi-recumbent bicycle to hold all of his gear. The motor controller, charge controller, battery packs, and lighting system were all his own design. He has a captivating 2 hour presentation embedded below in which he describes all the problems he had with his equipment during the trip as well as all the great experiences the journey offered.

Chainsaw Powered Bicycle

chainsawbike

We’ve covered weed whacker bicycles before and you can even buy 66cc conversion kits now. [geoff390] posted a few videos over on YouTube about another motor option. In the first video embedded below, he goes over the basic parts of his bike. The chainsaw motor is mounted to the side of the back tire and a metal drive wheel extending from the chainsaw shaft makes contact with it. The motor assembly is mounted on a hinge and the friction between the drive wheel and the back tire is adjusted with a turnbuckle. He posted a more detailed second video in which he goes over some of the finer details of the bike and some of the issues he’s had. Continue reading “Chainsaw Powered Bicycle”

RGBike POV

[Hazard] wanted a full color POV display for his bike wheel. Adafruit’s SpokePOV is single color and Monkeylectric’s original version didn’t display images. He also balked at the cost and decided to manufacture his own version. It uses 16 RGB LEDs on a single layer board he manufactured himself. It’s an entirely through-hole design to make assembly easy. It uses a hall effect sensor to synchronize the image display. The two main components are an ATmega328p microcontroller, which should make it Arduino compatible, and a TLC5940 PWM LED driver. It’s a very well documented build and certainly a good looking effect.

CrossCanada: A Biking Documentary

bike_arm

[Mike] was going to be biking across Canada. He really wanted to document the trip, so he began planning ways to get still images taken at intervals along the way. After a bit of brainstorming, he ended up setting his goals a bit higher. He was going to film the entire trip. He really didn’t want a simple helmet cam, he wanted himself and the entire bike in the frame. To do this he had to build a long arm on which he mounted a bullet cam. On his handlebars, he has a simple control where he can turn the system on and off as well as initiate recording.

No single piece of this project was too complicated, but taken all together, the final result is quite nice. You can watch the video for yourself after the break.

An Amazingly Professional LED Bike Light

light1

[Tom] sent us a link to this very professionally done project. He built a bike light that is a 540 lumen Luxeon light with a custom case.  The LED, Lens, and driver were purchased first. Everything else was designed around it. The design is compact and good looking. You can download the CAD files on the site if you want to make your own. He is using an Atmel AVR ATTiny13 to control brightness.

How To Properly Dispose Of Fruitcake

While doing serious fruitcake research, (no, really) we stumbled across the Great Fruitcake Toss held every January in Colorado. The particular entry above caught our eye. Omega 380 was built by a group of Boeing engineers and currently holds the distance record of 1,420feet. It’s a large compressed air cannon. All pressure is human generated using an exercise bike turning a pump. Apparently the team’s first contest entry was a classic surgical tubing slingshot. It eventually broke down during a very cold year, so they switched to this newer design. You can see more videos on the Operation Fruitcake blog.
