Audi e-bike Official - A bicycle that runs at 80 kmph HD
~ Audi e Bike - A bicycle that runs at 80 kmph .. .. .. !! Audi unveiled an extremely emotion-inspiring sports machine, the Audi e-bike Wörthersee at Wörthersee in Carinthia, Austria. The prototype cycle combines an electric drive and muscle power. Head of Design Wolfgang Egger comments: "As a high-performance e-bike for sports and trick cycling, it features the Audi core competences of design, ultra, e-tron and connect." The Audi e-bike Wörthersee puts in its first major appearance at this year's Wörthersee Tour, the 31st meet for Audi, VW, Seat and Skoda fans; trial biker Julien Dupont and downhill specialist Petra Bernhard will demonstrate their stunts and streetbike skills. As a high performance e-bike for sports and trick cycling, it features the Audi core competences of design, ultra, e-tron and connect." Wolfgang Egger, Head of Design said. The bike looks dynamic, but is also designed to be functional. All design elements are secondary to the technical features. The airy frame boasts a low centre of gravity and a compact overall volume. In this way, the e- bike is agile. The lithium-ion battery is incorporated into the frame and needs 2.5 hours to fully charge and is easily replaceable. The frame and the swinging arm that holds the back wheel are made of carbon fibre-reinforced polymer (CFRP). The same material is used for the 26" wheels, which feature broad flat spokes for an optimized transmission of pedal power. The signature Audi LED lights are also present at the front and back of the bike. For extreme tricks and stunts the seat can be lowered to run flush with the frame itself. At the press of a button, the seat then rises up and the biker can adopt a comfortable position. The electric motor is located at the lowest point on the frame and drives the bottom bracket shaft directly. The maximum torque delivered to the rear wheel is 250Nm. The electric motor generates a maximum output of around 3bhp. The complete bike excluding electrical components weighs 11kg.

The Matra MS1 Electric Bike - Newest fashion electric bike
This could be a great commuting machine, it's an electric powered bike designed by the French company Matra.The aluminum frame hybrid weighs in at just 40 kg (with batteries) and features 100 mm suspension forks and 400 mm front disc brakes up front, plus regenerative braking to extend the battery life. Recharging time is estimated at 3 -- 6 hours. The MS1 starts via a magnetic card swiped through the LCD display on the handlebars (which also indicates remaining battery power and speed) and an electric alarm is included along with LED lights for night-time commuting. Another notable feature often omitted from both motorcycle and bicycle design is the ability to adjust the height and depth of the saddle and handlebars.Now this bike should be available for sale in Europe, but no word on whether it'll make it to the States. It will probably be priced around $3500 - 5000$.

Water Powered Car Inventor was Killed!
http://SaveGasForums.com This is an old clip shown about 20 years ago of a local inventor holding many patents on his dune buggy style car. His name was Stanley Meyer. Look his name up, and you'll get to know more about his invention, and the mysterious way he "died". For all the people out there saying this is some kind of scam, you should take the time to read up on the numerous personal achievements of people who have successfully created their own water-powered cars. ALSO, take the time to look into the companies that have successfully created water powered cars. A Japanese company in another one of my videos has done just this!

50 MPH 8000W AWD Electric Offroad Mountain Bike First Drive
Be sure to follow us: http://instagram.com/hpcbikes https://www.facebook.com/HPCBikes Dual motor e-bike reaching very fast speed of 47-48 mph in minimal space. Bicycle as seen is running at 5600W with 2WD. This bike does come with the option of running at 8000W or 5600W. We chose 5600W because we felt 8000W is not needed and just spins the tires needlessly and also puts added stress on components. The pull is quite amazing on this thing. This particular video is the first impressions of our first ride. The space we ran it is just slightly downhill but also around a bend so there is less than 350 feet to really get on the throttle. Later testing on flat ground yielded 50 MPH on GPS and Radar! Total system weight ready to ride is only 65 lbs! (29.5 kg!) 8000w kit reaching fast speeds with amazing hill climbing Visit us at www.hi-powercycles.com Thanks for watching!

Stealth Bomber Electric Bicycle Ride
My 2013 Stealth Bomber electric bicycle. Stealth is a good description of this bike. If you're lucky enough to see one on the street, you'll notice there's not much to see, nothing to hear, and it happens quickly. I call it Electronaut. 72V, 18Ah LiFePO4 battery, Special Crystalyte 5403 750w/4500w rear hub motor, Crystalyte 65A controller, V Boxx 9 speed pedal gearbox, Magura 203mm MT2 hydraulic disk brakes, Cycle Analyst CAV3, RST R1 forks adjustable for compression, and rebound, DNM shock w/remote, adjustable for pre load, compression, and rebound, , A full 18ah charge takes 3 hours, but a more typical 12ah charge takes about 2 hours. The manufacturer claims a battery life of 800 cycles.. Silent running, vibration free, and trouble free.. Range depends on the speed you're riding. 20 mph yields a range of 50 miles with light pedaling. I bought this bike online from, Road Bike City, in L.A.

Haibike eQ Xduro - Motorschaden mit Bosch nach drei Monaten täglichen Einsatzes
Seit 1. April ist dieses Pedelec-MTB tagtäglich im Einsatz, Tausende Kilometer und Zigtausende Höhenmeter hat es somit zu leisten gehabt. Schon nach einem Monat fiel ein eigenartiges Klackgeräusch (aus dem Getriebe?) auf, nun - nach weiteren zwei Monaten - war wohl dieses Klacken Ursache für einen Motorschaden, der bei der abendlichen Fahrt nach über 450 Höhenmetern urplötzlich auftrat. Vorerst fiel der Verdacht noch auf die Speedhub-Nabe, daß diese vielleicht den Anforderungen doch nicht gewachsen wäre. Doch ein Aushaken der Kette und alleiniges Drehen der Kurbel brachte die Sicherheit: Der Motor war hinüber. Und es dürfte wirklich der Motor sein, denn das Getriebe macht bei ausgeschaltetem Gerät noch mit, im eingeschalteten Zustand jedoch läßt sich die Kurbel kaum mehr drehen. Im Gegensatz zu einem BionX-Motorschaden (leider schon dreimal (!) erlebt), läßt sich dieses Haibike mit defektem Bosch-Motor noch bewegen, wenn auch nur mit Bedacht und wenig Drehmoment, denn die Geräusche aus dem Getriebe waren nun kein Klacken mehr, sondern ein ständiges Scheuern und Schaben.

BOSCH E-Bike System Erweiterung : Datenlogger Speedict + Android Display
Der Speedict Datenlogger speichert elektrische und Tourdaten und zeigt diese über Bluetooth auf einem Android Smartphone ( Ver2.0 oder höher ), dessen GPS er gleichzeitig einbindet. Die Live Anzeige des aktuellen Energieverbrauchs, der verbrauchten Kapazität, sowie der momentanen und Spitzenleistungsaufnahme, ermöglicht sowohl sparsamen Betrieb, als auch die Berurteilung der Unterstützungsleistung bei verschiedenen Betriebszuständen. Zwar verfügt das BOSCH eBike System über diese Daten, stellt sie jedoch nicht dar. Insofern geradezu eine zwingende Ergänzung für ambitionierte Pedelec Fahrer , ebenso wie die gegenüber dem BOSCH System umfangreicheren und brauchbaren Tachofunktionen. Das bei eingelegter SIM Karte auch Kartendarstellung (Live Plot) geboten wird, ist ebenfalls nützlich. Das GPS und die sonstigen Live Daten benötigen indes keine Datenverbindung bzw. SIM Karte. Die auch ohne Android Smartphone gespeicherten Datenlogs (ohne GPS) können später mit der Speedict Software am PC ausgewertet werden bzw. auf den Speedict Server hochgeladen werden. Der Einbau gestaltet sich unproblematisch, da der Speedict Logger nur in die Verbindung der Batterie eingeschleift werden muß und über diese versorgt wird . Der Speedsensor bedarf keines extra Speichenmagneten und kann mit dem voreingestellten Reifenumfang des BOSCH Tacho synchronisiert werden.
