Our frame is made from bamboo that has been treated to prevent splitting. We offer our bamboo bicycle frames in all frame styles and geometries.

The Bicycle Academy : Cycle frame building school | Make a bike. Make a difference. Learn how to build a bicycle frame, keep the skills and give your first bike to someone who really needs it. We give people the lessons, skills and kit to design and make their own bikes. But there’s a big difference. We’ve based our TBA Africa bike on the Buffalo Bike designed specifically for people in Africa. We know frame-building classes aren’t cheap and if you don’t have a workshop nearby with all the kit it’ll be hard for you to make another bike.

Home | Panda Bicycles The secret history of 19th century cyclists | Environment It is not easy explaining to family and friends why you are spending a fairly considerable amount of money and a year of your life researching the social impact of the bicycle on late19th century British society. As an uncle of mine, who is himself a keen cyclist, once helpfully asked, “Why does anyone need to know anything about that?” It can be a difficult question to answer. As with most people involved in academic research, there are many personal reasons why I’m doing it. Having such experiences meant that when I stumbled across cycling sources from the 1890s, it was easy for me to find them fascinating, and above all else, easy to relate to. The 100 and something years separating myself from those I was researching disappeared when reading accounts like this: To find oneself miles from anywhere, with the mossiest of banks inviting a loll, a smoke and a quiet chat with congenial clubmates – to experience these things is to taste the real sweets of the cyclists’ existence.

Capitalism is making way for the age of free | Jeremy Rifkin A 3-D printer producing a canal house in the Netherlands. A legion of prosumers is producing and sharing 3D printed products at near-zero marginal cost on the collaborative commons. Photograph: Peter Dejong/AP Karl Marx spent a lifetime trying to uncover what he suspected were the deep contradictions that drove the capitalist system forward but that would one day lead to its demise. In a capitalist market, governed by the invisible hand of supply and demand, sellers are constantly searching for new technologies to increase productivity, allowing them to reduce the costs of producing their goods and services so they can sell them cheaper than their competitors, win over consumers and secure sufficient profit for their investors. Over the past decade millions of consumers have become prosumers, producing and sharing music, videos, news, and knowledge at near-zero marginal cost and nearly for free, shrinking revenues in the music, newspaper and book-publishing industries.

Bamboo bikes, local materials for innovative solutions The Victorian Cyclist | A history blog on the joys and perils of cycling in Victorian Britain Tomorrow's Apps Will Come From Brilliant (And Risky) Bitcoin Code | Wired Opinion For many, bitcoin — the distributed, worldwide, decentralized crypto-currency — is all about money … or, as recent events have shown, about who invented it. Yet the actual innovation brought about by bitcoin is not the currency itself but the platform, which is commonly referred to as the “blockchain” — a distributed cryptographic ledger shared amongst all nodes participating in the network, over which every successfully performed transaction is recorded. And the blockchain is not limited to monetary applications. Borrowing from the same ideas (though not using the actual peer-to-peer network bitcoin runs on), a variety of new applications have adapted the bitcoin protocol to fulfill different purposes: Namecoin for distributed domain name management; Bitmessage and Twister for asynchronous communication; and, more recently, Ethereum (released only a month ago). The Bitcoin Protocol Is More ‘Cloud’ Than ‘P2P’ So What Are the Challenges? That’s the revolutionary feature of Ethereum.

Road Bikes | Bamboosero "I had a beautiful 25 mile ride this morning before church services (I am a Lutheran pastor). It is smooth, comfortable and quick--average speed 17.9 mph. My average speed is up about 2 mph over the Madone. Robert Jones "First impressions are good - stiffness will not be a problem as I actually found it very stiff compared to my current bikes. Brendan Millar Distance: 4,368.9miles (7,281.5km) Bamboo bike1 record (before accident): 2,979.3miles, 2010/9/10-10/28 Bamboo bike2 record (after accident): 1,389.6miles, 2010/11/11-12/6 Start/Goal: from Bamboosero in Santa Cruz, CA to Bamboobikestudio in Brooklyn, NYC "The bamboo bike rides really nicely-stiff like aluminum, probably due to the oversize tubes, er, sticks, but more muted like a nice steel frame. Paul Altenhofen (Calfee Bamboo Bike January 2008) "[My] initial concerns before riding the bike would have been the geometry, balance, and alignment of an imperfect material of non man made origin.

Is It O.K. to Kill Cyclists? Photo SAN FRANCISCO — EVERYBODY who knows me knows that I love cycling and that I’m also completely freaked out by it. I got into the sport for middle-aged reasons: fat; creaky knees; the delusional vanity of tight shorts. Registering for a triathlon, I took my first ride in decades. I made it home alive and bought a stationary bike trainer and workout DVDs with the ex-pro Robbie Ventura guiding virtual rides on Wisconsin farm roads, so that I could sweat safely in my California basement. The anecdotes mounted: my wife’s childhood friend was cycling with Mom and Dad when a city truck killed her; two of my father’s law partners, maimed. In stories where the driver had been cited, the penalty’s meagerness defied belief, like the teenager in 2011 who drove into the 49-year-old cyclist John Przychodzen from behind on a road just outside Seattle, running over and killing him. You don’t have to be a lefty pinko cycling activist to find something weird about that. Take Sgt.

Reportaje: - "La democracia consiste en limitar el poder" París, 12 de octubre 2013. Cuando Tzvetan Todorov cruzó la puerta del Café La Contrascarpe, en la plaza del mismo nombre, ubicada en un recodo de París al que se llega cruzando un laberinto de calles escuetas pobladas de pequeñas boutiques, no dejó dudas de su familiaridad con el lugar. De un golpe de vista ubicó la mesa donde yo estaba sentado y extendió su mano en gesto hospitalario y con un movimiento tan ágil que me dejó la impresión de estar ante un hombre mucho más joven de lo que dicen sus documentos de identificación. Pasamos al fondo de un salón con mobiliario de madera y paredes tapizadas de verde que le daban al lugar cierto paradójico aspecto británico. Por más que su actitud atenta llamara la atención, lo que importaba de verdad era lo que él tenía que decir. Usted es un defensor de la Ilustración como conjunto de principios e ideas que pueden ayudarnos a salir de la actual crisis civilizatoria.
