reTyre - first zip-on tire system

reTyre - the first zip-on tire system!

Casual cyclists tend to have one bike suited for mild terrain. Meanwhile, “serious” cyclists often have multiple bikes to tackle specific riding — urban commuting, mountain biking, winter riding, and more.
But Norwegian startup reTyre wants to take a serious cyclist’s versatility and combine it with the simplicity of a casual cyclist’s single-bike quiver. And believe it or not, it aims to accomplish that with zip-on tire treads.
The concept is both as wild and as basic as it sounds. A tiny zipper along the sidewall allows users to zip on studs or tread over a smooth road tire. And it claims to work on standard rims and just about any size.
The brand offers three “skins” to accommodate changing conditions. An urban winter tire sports 156 carbide studs. An all-terrain skin works for gravel and other soft, uneven surfaces with a light tread pattern. And the Trail X skin handles aggressive downhill mountain riding.

Convercycle Bike - City Bike & Cargo Bike in one!
The folding process reportedly takes just three seconds, and can be done with one hand.
Once in cargo mode, the bike can carry up to 60 kg (132 lb) in its rack,
along with a rider weighting up to 120 kg (265 lb) on the seat.
The bike itself tips the scales at 18 kg (40 lb),
with its rack sitting at a width of 43 cm (17 inches) – that's no wider than the handlebars.

David Maurer-Laube designed the first draft of the Convercycle in 2017. He studies product design at the University of Art and Design in Offenbach/Germany.
The manager team now consists of 8 members. The pre-production will start in February 2019


Chainless drivetrain

Producer: CeramicSpeed | Advertising Video Eurobike 2018

New innovative bicycle gear system.
CeramicSpeed used Eurobike 2018 to show off its Driven 13-speed pinion drive shaft concept, which swaps derailleurs and chains for a drive shaft that it claims provides 49% less friction with a near 99% efficient drivetrain.
Jason Smith from CeramicSpeed explains the new innovative bicycle gear system.


Schwalbe Airless

"No air = No more flats"

Driving with the Schwalbe Airless System means 100 percent maintenance-free cycling. The elastic thermoplastic polyurethane ensures a light flow and comfort.
The driving characteristics are comparable to those of a bicycle tire on air. The Airless tube has an excellent damping, offers a lot of comfort and even gives an energy boost thanks to the excellent flexibility of the material.

Downsides are a slightly higher rolling resistance, a marginally higher weight when compared to tubes and the need of a machine for mounting the tires.

The Schwalbe Airless system is now first available in size ETRTO 40-622 (28 inch). The 'feel' of the tire is like 3.5 bar air pressure of a normal inner tube.


Airless bicycle tires

Producer: ERW©

Welcome to the future of bicycle technology.
The benefits of removing the air from tires completely has been known since the beginning. ERW© Patented Airless Design make bicycling safer and more efficient. Obstacles slide under the ERW© wheels with precision and ideal comfort, and keeping the tread on the tire. The design can be created to have fully adjustable tread ride comfort, road or trail conditions.


Samsung Smart Bike

Producer: SAMSUNG | Advertising Video

Thanks to the experience of Maestro Giovanni Pelizzoli -- a world famed frame builder- and the talent of a young student of Samsung Maestros Academy -- Alice Biotti -- Samsung Smart Bike came alive. This is the first bicycle that protects the rider thanks to its safety components, controlled by a Samsung Smartphone. It comes with an innovative bicycle-frame that neutralizes the most dangerous vibrations to the human body, 4 laser beams to alert other drivers that the bike is coming along, an integrated GPS system to tell local authorities which routes should be immediately turned into real bike-lanes. This is Samsung Smart Bike, the perfect mix between future and heritage, presented with great success during the 2014 Milan Design Week.


Bicycle self balance

Producer: TEDx | Lecturer: Prof. Arend Schwab

Why bicycles do not fall

Arend Schwab is professor in theoretical and applied mechanics from Delft University of Technology.
He runs the bicycle mechanics lab and teaches mechanics.

Whenever Arend comes up with an assignment for his students, the hallway of the faculty is crammed with all sorts of very strange objects that resemble bikes only slighlty. Considering bicyles constitute 40% of the Netherlands traffic making it the bicycle capital of the world, his work is very interesting not only for the dutch people but anyone who ever rode a bicycle.

Amongst his fields of interest are: Multibody Dynamics, dynamics of flexible multibody system, finite element method, legged locomotion, speed skating, and bicycle dynamics. In particular the treatment of contact phenomena like in collisions and rolling (non-holonomic constraints) is his special interest. He has given academic talks related to his area of expertise in various universities all over the world.


Invisible bicycle helmet

Inventing the impossible: An invisible bike helmet
Swedish engineering design students Anna and Terese took on a giant challenge as an exam project. Something no one had done before. If they could swing it, it would for sure be revolutionary. The bicycle is a tool to change the world. If we use bikes AND travel safe: Life will be better for all.


Human-Powered Helicopter: Straight Up Difficult

Producer: Maggie Starbard

Nothing is impossible! problem, just challenge :-)
It's difficult to build a working four-rotor helicopter, when the engine is a person with a power of only some hundred watts. But one team of engineering students is trying to do just that.
Students from the University of Maryland are chasing one of aviation's last milestones: the Sikorsky Prize. The American Helicopter Society (AHS) has promised $250,000 to the team that can build a human-powered helicopter. All it has to do is hover for a minute, reach a height of 3 meters, and stay in a 10-meter box.
