bicycle wheels

Danny MacAskill tries to destroy carbon fiber bike wheels by riding trials tricks through downtown Glasgow, including on bare rims on concrete.

Arend Schwab demonstrates a research bicycle, the two-mass-skate design, that balances itself without gyroscopic effects or trail. It challenges the common explanations for why a moving bicycle stays upright.

A short clip of Steve Jobs describing the computer as a bicycle for the mind. He compares human efficiency of travel to what computers do for mental work.

Nine minutes of unedited footage of a very busy bicycle and car crossing at Korte Prinsengracht and Haarlemmerstraat in Amsterdam. Cyclists, pedestrians and cars flow through without traffic lights.

A short minutephysics video explaining why bicycles stay upright. It looks at gyroscopic precession, head angle and centre of mass, and shows that bikes self-steer toward the direction they lean.

Google Netherlands' April Fools' 2016 video presents a fictional self-driving bicycle for Amsterdam, framed as a serious product launch.

A sped-up two-minute view of morning rush hour at a busy Utrecht junction, where thousands of bicycles and buses pass each day. It illustrates a city where about a third of trips are by bike.

A short clip from the 1983 BBC series Fun to Imagine in which Richard Feynman explains how a train stays on the track. He covers the geometry of tapered wheels that steer the train back toward the center of the rails.

A two-minute minutephysics video explaining why turning a bicycle requires first steering briefly the other way. It covers counter-steering and balance with slow-motion footage and 3D animation.

A five-minute BicycleDutch episode showing how Dutch junctions are designed so cyclists and pedestrians can cross safely. It explains the layout choices that separate and protect them.

A short clip of Richard Feynman explaining how a train stays on its tracks, through the conical shape of wheels and how it handles curves without differentials.

A demo of the Cubli, a 15 cm cube that uses reaction wheels to jump up onto a corner, balance there and fall in a controlled way to move. The video shows these three abilities chained into locomotion.

Veritasium explains why bicycles are stable, arguing that gyroscopic effects are not the answer. The video shows countersteering and an experiment where riders blocked from steering the opposite way cannot turn.

Copenhagen's bicycle ambassador Mikael Colville-Andersen argues in a TEDx talk that bicycle helmets threaten bicycle culture. He says they distract from road design and make cycling look dangerous.

An expat YouTuber in China shows how dockless bike-sharing, once loved, has been flooded by competing companies. Bikes pile up, get abandoned in odd places and are vandalised, with footage from around the city.

Not Just Bikes explains how an electric bakfiets (Dutch cargo bike) replaced the family car after a move back to Canada, saving thousands of dollars. It shows how much it can carry, including kids and groceries.

Not Just Bikes explains why upright Dutch-style bicycles are comfortable and practical, and why they are rare outside the Netherlands.

AI Addict films a Tesla FSD Beta 8.2 drive through Oakland, annotating close calls, disengagements, pedestrians and wrong-lane moments with timestamps.

Mike Boyd takes up Smarter Every Day's challenge to learn to ride the Backwards Brain Bike, a bicycle whose steering is inverted, and rides 50 meters. It shows how hard it is to unlearn a motor skill.

A short BicycleDutch video on how the Netherlands got its cycling infrastructure, including the 1970s protests and the shift away from car-centric planning. The channel later published an updated version.

Aging Wheels compares a road trip in a Polestar 2 with an identical drive in a Tesla, showing the charging problems of non-Tesla EVs. It argues that outside Tesla's network, EV road trips have become frustrating.

A short BicycleDutch episode showing how people with disabilities use Dutch cycle tracks on hand-cycles, tricycles and mobility scooters.

Aging Wheels tests how towing trailers affects the range of electric trucks, including a Silverado EV. It shows that trailer aerodynamics matters far more than added weight.

A short BicycleDutch episode showing Vredenburg in Utrecht, the busiest cycle path in the Netherlands, with about 37,000 cyclists passing on a working day.

A short BicycleDutch episode showing how Dutch protected intersections continue cycle paths through the junction without needing extra street width.

A short BicycleDutch episode showing how Dutch junctions with protected cycle paths are laid out. It argues these are proven, non-experimental designs that make intersections safer for cyclists.

Streetfilms shows how Utrecht reduced car traffic in its center by removing roadways, building huge bike parking near the train station, and making cycling transitions safer and easier.

A 1937 GM-produced film explaining how the automobile differential lets wheels turn at different speeds around a corner. It uses clear animations and cutaway demonstrations to build the idea from first principles.

California Superbike School demonstrates its 'No B.S.' bike, which has fixed handlebars so riders can only steer with body lean. It illustrates how little control that gives compared with countersteering.

Rare footage of Steve Jobs giving a 22 minute presentation about Apple in 1980, donated to the Computer History Museum. In it he explains the company name and the bicycle-for-the-mind idea for computers.

In this Top Gear segment Jeremy Clarkson tries to roll a Reliant Robin three-wheeler through Barnsley, with celebrity helpers trying to keep it upright. The car keeps tipping over.

Not Just Bikes explains Dutch bicycle-only roads, which let people travel long distances in and out of cities with almost no car interaction. It shows how this changes cycling from a chore into something enjoyable.

A short Inside Edition segment on Daniel Kish, a blind man who uses tongue clicks as human sonar to ride a bicycle through city traffic. He explains that he hears the reflections of the sounds off objects.
