Stalking the Bamboo Bike by Joe Lapp December 2013
Stalking the Bamboo Bike by Joe Lapp December 2013 In an African country with few safari animals, what’s to pounce on instead? Locally grown two-wheelers. The first time I see Craig Calfee, creator of the carbon fiber bicycle and pioneer of the modern bamboo bike movement, he’s leaning out of a moving minivan in Ghana, West Africa, trying to get my attention. His gray curls dance as the van races toward a green left-turn arrow. His right arm waves madly from a torso stretched out of the careening van’s side-door window. He’s a man committed. I’d been standing on that corner – with West African practicality called Kaneshie First Light, the first stoplight after Kaneshie market – hoping he’d show. It’s not hard for two white guys in Ghana to find each other. Our meeting is a fluke, though Craig’s presence in Accra, Ghana’s coastal capital, is no accident. He’s checking up on Ghanaian bike builders he trained to make two-wheeled wonders from a plant. Yes, a plant. Africa. Name it and an American might think: starving babies, stark deserts, dense jungles, rebel groups high on drugs. The continent doesn’t often present itself as a center of innovative design fueling a green revolution. But if Craig Calfee has his way, that’s going to change. Ghana. Name the nation and the American looks thoughtful: here’s a country she knows she’s heard of, though she couldn’t place it on a map. Think famed West African slave castles. -
BAMBOO, the Wonder Material to Reinvent Mobility
BAMBOO, the wonder material to reinvent mobility. “Automotive, Sports and Recreation Industry” Iván Platas 1 and Karl Niklass 2 1. Corresponding author: [email protected]; +34 696 71 39 21. Spain. 2. Corresponding author: [email protected]; +43 699 1000 4220. Austria. Abstract. The following article is a general reflection on the evolution of the use of bamboo in solutions for human mobility, from the early day bicycles to the actual automotive industry, demonstrating that bamboo can be a wonder material to reinvent the way vehicles are conceived. This paper also presents the creation of the world’s first bamboo soapbox racer developed in 2017 as the initial project on a more ambitious plan to develop light, efficient, safe, renewable materials made vehicles. Bamboo has been used as a construction material over centuries to build from simple shelters to towers and bridges and the scaffolding used to build them. Due to the lightweight to strength ratio, Bamboo is a versatile material that has also been used in many other products as fishing rods, musical instruments, kitchen utensils and bicycles. The knowledge and experience acquired over the years together with the manufacturing techniques available today make bamboo and bamboo engineered products to set the key to lightweight and efficient-clean vehicles construction. The transport sector is the largest contributor to NOX emissions inside the cities accounting for 46 % of total EU-28 emissions in 2014 according to the “Air quality in Europe - 2016 report” published on the 2016 by the European Environment Agency. While the population is increasing in urban areas, the quality of the air that citizens breathe is decreasing rapidly. -
Shooting Star: a Biography of a Bicycle
SHOOTING STAR: A BIOGRAPHY OF A BICYCLE Geoff Mentzer 2 SHOOTING STAR: A BIOGRAPHY OF A BICYCLE Copyright © 2020 by Geoff Mentzer All rights reserved. 3 In a scientific study of various living species and machines, the most efficient at locomotion – that is, the least amount of energy expended to move a kilometre – was found to be a man on a bicycle. –SS Wilson, Scientific American, March 1973, Volume 228, Issue 3, 90 The Dandy Horse of 1818, said to be the first velocipede man-motor carriage. Sharp, Bicycles & Tricycles: An Elementary Treatise On Their Design And Construction, Longmans, Green, and Co, London, New York and Bombay, 1896, 147 4 INTRODUCTION AND ACKNOWLEDGEMENTS What began as a brief biograph of the author's forebear Walter William Curties soon doubled into a study of two men, and expanded into an account of early bicycle – and a little motoring – history in New Zealand. Curties is mostly invisible to history, while Frederick Nelson Adams – who rose to national pre-eminence in motoring circles – by his reticence and reluctance for public exposure is also largely overlooked. Pioneering New Zealand cycling and motoring history – commercial, industrial and social – have been variously covered elsewhere, in cursory to comprehensive chronicles. Sadly, factual errors that persist are proof of copy and paste research. As examples, neither Nicky Oates nor Frederick Adams' brother Harry was the first person convicted in New Zealand for a motoring offence, nor was the world's first bicycle brass band formed in New Zealand. It must be said, however, that today we have one great advantage, ie Papers Past, that progeny of the Turnbull Library in Wellington. -
The History of the Wheel and Bicycles
NOW & THE FUTURE THE HISTORY OF THE WHEEL AND BICYCLES COMPILED BY HOWIE BAUM OUT OF THE 3 BEST INVENTIONS IN HISTORY, ONE OF THEM IS THE WHEEL !! Evidence indicates the wheel was created to serve as potter's wheels around 4300 – 4000 BCE in Mesopotamia. This was 300 years before they were used for chariots. (Jim Vecchi / Corbis) METHODS TO MOVE HEAVY OBJECTS BEFORE THE WHEEL WAS INVENTED Heavy objects could be moved easier if something round, like a log was placed under it and the object rolled over it. The Sledge Logs or sticks were placed under an object and used to drag the heavy object, like a sled and a wedge put together. Log Roller Later, humans thought to use the round logs and a sledge together. Humans used several logs or rollers in a row, dragging the sledge over one roller to the next. Inventing a Primitive Axle With time, the sledges started to wear grooves into the rollers and humans noticed that the grooved rollers actually worked better, carrying the object further. The log roller was becoming a wheel, humans cut away the wood between the two inner grooves to create what is called an axle. THE ANCIENT GREEKS INVENTED WESTERN PHILOSOPHY…AND THE WHEELBARROW CHINA FOLLOWED 400 YEARS AFTERWARDS The wheelbarrow first appeared in Greece, between the 6th and 4th centuries BCE. It was found in China 400 years later and then ended up in medieval Europe. Although wheelbarrows were expensive to purchase, they could pay for themselves in just 3 or 4 days in terms of labor savings. -

DAVID V HERLIHY THE VELOCIPEDE CRAZE IN MAINE In early 1869\ when the nation experienced its first bicycle craze, Maine was among the hardest-hit regions. Portland boasted one of the first and largest manufacto ries, and indoor rinks proliferated statewide in frenzied anticipation of the dawning “era of road travel. ” In this article, the author traces the movement in Maine within an international context and tackles the fundamental riddle: Why was the craze so intense, and yet so brief? He challenges the conventional explanation - that technical inadequacies doomed the machine - and cites economic obstacles: in particular, the unreasonable royalty demands imposed by Maine-born patent-holder Calvin Witty. David V. Herlihy holds a B.A. in the history of science from Harvard University. -

Contact: [email protected] Bikes and the Brooklyn Waterfront: Past, Present, and Future Brooklyn and the Bicycle by David V. Herlihy Across the United States, cycling is flourishing, not only as a recreational activity but also as a “green” and practical means of urban transportation. The phenomenon is particularly pronounced in Brooklyn, a large and mostly flat urban expanse with a vibrant, youthful population. The current national cycling boom encompasses new and promising developments, such as a growing number of hi-tech urban bike share networks, including Citi Bike, set to launch in New York City in May 2013. Nevertheless, the present “revival” reflects a certain historical pattern in which the bicycle has swung periodically back into, and out of, public favor. I propose to review here the principal American cycling booms over the past century and a half to show how, each time, Brooklyn has played a prominent role. I will start with the introduction of the bicycle itself (then generally called a “velocipede” from the Latin for fast feet), when Brooklyn was arguably the epicenter of the nascent American bicycle industry. 1 Bikes and the Brooklyn Waterfront: Past, Present, and Future Velocipede Mania The first bicycle craze, known then as “velocipede mania,” struck Paris in mid- 1867, in the midst of the Universal Exhibition. -

Engineering a Bamboo Bicycle
Engineering a Bamboo Bicycle A Major Qualifying Project Report Submitted to the Faculty of Worcester Polytechnic Institute In partial fulfillment of the requirements for the Degree of Bachelor of Science in Mechanical Engineering Authors Safety and Testing: Jonathan Arnone Roger Blanchard Robert Harasimowicz Liyuan Shen Jig: Jackson Beall Michael Conte Samuel Johnston Joints: Katherine Longhurst Bipul Pyakuryal Samuel Teatum Adam Trumbley Dana Valentine 30 April 2015 This report represents the work of WPI undergraduate students submitted to the faculty as evidence of completion of a degree requirement. WPI routinely publishes these reports on its website without editorial or peer review. For more information about the projects program at WPI, please see: http://www.wpi.edu/academics/ugradstudies/project-learning.html Abstract The primary objective of this Major Qualifying Project was to design and construct a bamboo bicycle that could be made available in developing nations and be assembled quickly with minimal training. In order to meet this objective, the project was decomposed into three main components: bicycle joint design, manufacturing fixture design, and safety and testing. The project team was divided into three corresponding groups, utilizing axiomatic design to break down each of the three components. The Joints Team created a system of gussets to transmit rider loads between bicycle frame members. The Jig Team designed a device that will enable an individual with minimal training to assemble a bamboo bicycle frame by maintaining component alignment during bicycle frame assembly. The Safety and Testing team designed bicycle frame tests to meet ASTM standards to ensure the safety of all potential riders. -

Finite Element Analysis of a Wheelchair When Used with a Front-Attached Mobility Add-On
Finite Element Analysis of a Wheelchair when Used with a Front-Attached Mobility Add-On by Colleen Ogilvie B.A.Sc., Queen’s University, 2013 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF APPLIED SCIENCE in THE FACULTY OF GRADUATE AND POSTDOCTORAL STUDIES (Biomedical Engineering) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) November 2019 © Colleen Ogilvie, 2019 The following individuals certify that they have read, and recommend to the Faculty of Graduate and Postdoctoral Studies for acceptance, the thesis entitled: Finite Element Analysis of a Wheelchair when Used with a Front-Attached Mobility Add-On submitted by Colleen Ogilvie in partial fulfillment of the requirements for the degree of Master of Applied Science in Biomedical Engineering. Examining Committee: Dr. H.F. Machiel Van der Loos Supervisor Dr. Jaimie Borisoff Supervisor Dr. Mattia Bacca Supervisory Committee Member Dr. Jasmin Jelovica Supervisory Committee Member ii Abstract Over the past two decades, a variety of mobility add-ons for manual wheelchairs have emerged in the assistive technology industry, including pushrim-actuated power-assist wheelchairs, motorized propulsion aids, manual and motorized front-end drive attachments, and passive attachable wheels. These technologies are typically used by long-term lightweight manual wheelchair users including those from spinal cord injury populations, and increase the mobility capabilities of the wheelchair, such as through the addition of all-terrain wheels or power-assistance. Currently, little is known about how mobility add-ons affect the durability, strength, and lifespan of manual wheelchairs, and whether they increase the risk of component failures. In particular, very little research has assessed the likelihood of failures associated with front-attached mobility add-ons.
