Cycles of Change

Engineering practical systems and exploring the physical world.

Selecting an expedition electric bicycle is only the first step in preparing for self-supported touring. Once you possess a reliable Class 1 machine, practical survivability depends on outfitting decisions made before departing the driveway. Long-distance e-bike touring introduces acute mechanical [...]
Long-distance electric bicycle touring requires balancing five mechanical and regulatory realities. You must account for universal multi-use trail legality, massive payload stability, extended battery capacity exceeding one kilowatt-hour, low-maintenance drivetrain longevity under motor torque, and [...]
The foundation of everything in this guide is kefir, not the flavored, pasteurized kefir sold in bottles at supermarkets, but living kefir made fresh every day from a small cluster of grains and whatever whole milk is available locally. Understanding kefir is where everything else begins. Kefir [...]
For many, the Erie Canal Trail, part of the expansive Empire State Trail, represents a familiar and accessible pathway through New York's rich history. Along the way, cyclists often journey through Rome, NY, visiting the Fort Stanwix National Monument, a site that stands as a testament to [...]
Setting out upon the road with a loaded bike offers a freeing way to see the world. By trading consumer noise for two wheels and a pair of bags, a rider rediscovers travel at a human pace. Every pedal stroke connects the traveler with changing skies, winding valleys, and the physical shape of the [...]
The Call to a Deeper Journey To choose the path of the nomadic cyclist is to answer a call for a more profound way of living. It is a conscious decision to trade a life of accumulation for a life of experience. This philosophy extends far beyond the simple act of packing lightly; it is a form of [...]
A recumbent bicycle with a small front wheel and larger rear wheel makes a great base for an electric build. The 20-inch front wheel handles well in tight spaces. The 26-inch rear wheel rolls smoothly over rough roads. Adding an electric motor and a front-wheel generator turns this setup into [...]
Stretching across south-central New Mexico, Highway 380 crosses fifty-three solitary miles of high desert terrain between the Rio Grande village of San Antonio and the mountain town of Carrizozo. For the bicycle tourist, this empty corridor exposes the raw stony bones of the desert Southwest. The [...]
The simple act of riding a bicycle represents a significant step toward achieving personal freedom and fostering a deeper connection with the self. This journey involves a process of discovery that strengthens the body while clarifying the mind and enriching the spirit. The bicycle serves as a [...]
In a small garage filled with the faint smell of citrus degreaser and chain oil, the noise of modern life fades into quiet concentration. A bicycle rests upside down on its handlebars or rests clamped in a metal repair stand. The tools arrayed on the workbench tell a tale of focused purpose. Allen [...]
The identity of the road warrior is defined by a commitment to clear travel and the mastery of self-supported long distance trips. While often seen as a search for new things, the nomadic life represents a steady way to build mental strength and physical power. This path involves a simple way of [...]
Efficiency in human-powered transport depends on moving energy from the legs to the ground through a mechanical interface. Early bicycles used a direct-drive system where the pedals were attached to the front axle. This creation resulted in a massive problem for the rider because travel speed was [...]
