Bicycle Confinement Laboratory — Quick Guide

What You Can Learn for Your Own Bike

You don’t need a clean room to apply confinement science. Next time you store your bike for more than two weeks:

1. Hang it or stand it – but rotate which wheel touches the ground weekly to prevent flat spots.
2. Shift through the gears once every 7 days without riding (just turn the pedals by hand).
3. Leave a window cracked if in a shed—stale, humid air is worse than cool air.
4. Talk to it. (No evidence this helps. But no evidence it hurts either.)

Equipment

• Stationary bicycle (smart trainer or ergometer) with power accuracy ±2%.
• Mounting rig/adapter for different bike frames.
• Physiological monitors: chest or wrist HR monitor, 3-lead ECG (if clinical), pulse oximeter.
• Metabolic cart or portable indirect calorimeter for VO2/CO2 (if measuring gas exchange).
• Blood-pressure monitor (automated).
• Core temp sensor (ingestible pill or thermistor) if required.
• Motion capture or IMU sensors for cadence/position.
• Environmental sensors: CO2, temperature, RH, particulate monitor.
• Data acquisition system and computer with synchronized timestamps.
• Video camera for behavior/position recording.
• Communication system (intercom) and panic button.

Why Would Anyone Do This?

Great question. The Bicycle Confinement Laboratory exists because real-world riding masks slow failures. Bicycle Confinement Laboratory

When you ride every day:

• Tires flex and stay warm.
• Bearings spin and redistribute grease.
• Cables stretch and settle dynamically.
• Frames load and unload with each pedal stroke.

But store a bike for a long time—in an attic, a basement, or a climate-controlled shipping container—and you reveal hidden failure modes. Flat spots on tires. Frozen freewheels. Corrosion inside seat tubes. Brake levers that seize from lack of use. Bicycle Confinement Laboratory — Quick Guide What You

In other words: confinement is the ultimate test of a bicycle’s passive survival. Hang it or stand it – but rotate

What Exactly is a Bicycle Confinement Laboratory?

At its core, a Bicycle Confinement Laboratory is a hermetically sealed, airtight chamber that contains a stationary bicycle (ergometer) connected to a comprehensive suite of sensors. However, three critical features distinguish it from a standard exercise physiology lab:

1. Total Isolation: The chamber is sealed from the external atmosphere. Air exchange is controlled entirely by the facility's monitoring systems, not by HVAC drafts.
2. Environmental Manipulation: Scientists can alter temperature, humidity, barometric pressure, and gas composition (oxygen, CO2, nitrogen) to simulate everything from a tropical jungle to the summit of Everest or the cabin of a submarine.
3. Metabolic Closed Loop: Sensors measure every watt of power produced by the rider, every liter of oxygen consumed, and every gram of CO2 and water vapor exhaled.

The "confinement" is the operative word. While a standard stationary bike test lasts 20 minutes, a "confinement" protocol lasts hours, days, or even weeks.

Hygiene & Cleaning

• Sanitize contact surfaces, handlebars, saddle between participants.
• Replace or disinfect sensors per manufacturer guidance.
• Provide replacement towels and hand sanitizer.
