42 foot tricycle

As seen on Japanese television…


This huge tricycle built by Kanyaboyina Sudhaker of Hyderabad takes 300 pedal revolutions for each wheel revolution. The wheels on this 42 foot tricycle has wheels that are 17 feet across. This trike is in the Guinness Book of World Records as the world’s largest tricycle. Thank you to Roto1000 for this tip.

Bicycle snow plow

It’s been at least a year since somebody has mentioned David Peterson’s bicycle snow plow.

David Peterson's bicycle snow plow
Peterson rides his bike seven miles to his job at Fermilab in Chicago Chicagoland. When he built this snow plow for his bicycle several years ago, the bike paths he took to work weren’t plowed, so he started walking to work with a shovel and shoveling the path along the way. He soon moved up to a push plow, a contraption he pushes like a baby stroller with angled blades to push the snow to the side.

In 2002, he built his tow-behind snow plow.

david peterson and his bicycle snow plow
David Peterson posts the history and detailed construction plans for the bicycle snow plow at his website. I have no idea if he still uses this (the website was last updated in 2005), but I’ve sent Peterson an email and we’ll see what he says.

Here’s another bicycle snow plow photo I found randomly on the web.

More bike riders in San Francisco in 2007

The number of San Francisco bike riders rose by 15 percent from 2006 to 2007, according to a report by The City’s bicycle program.

In the study, which will be presented today at the Bicycle Advisory Committee, observers from the Municipal Transportation Agency’s Bicycle Program counted 6,454 cyclists on the streets during sample days in August 2007, which is 800 more than noted in 2006, the first year of the bicycle counting program.

James has some good links at Bicycle Design, including a story about an amazing all wood bicycle — the complete drive train is even made completely of wood and glue. I’m talking the chain, freewheel ratchet and cog. A 16 year old built that bike by hand as a school project.
