Audi Freestyle Wheelie Electric Bike Review

Audi Freestyle Wheelie Electric Bike Review

Audi Electric Bike Review

The German car and motorcycle manufacturer Audi is about to enter the electric bicycle market –  the top-of-the-line electric bicycle market. Audi unveiled their electric bike prototype at the Wörthersee car expo In May 2012. (Each May, the Volkswagen and Audi car show is held in the Austrian town of Reifnitz, adjacent to Lake Worth (Wörthersee) The car expo is typically just called Wörthersee.)

Audi’s entry into the electric bike market is significant for many reasons. Firstly Audi purchased the Italian motorcycle manufacturer Ducati in April this year for a reported $1.2 Billion. This gives Audi access to a worldwide dealership and distribution network. Automakers are realising that the future of transport will cover the full spectrum of vehicles and fuel types. The big auto brands have an unprecedented opportunity to expand their product range and brands into new markets that have traditionally not been their domain of expertise. The lines will continue to blur and Audi along with BMW and Smart are introducing commuter and performance electric bikes.

Also, while Europe and Asia have embraced the electric bike, citizens of the United States are still dragging their heels on adopting this technology (as well as that of electric motorcycles and electric cars.) Many US cities are undergoing planning changes that will increase cycle ways and reduce the reliance on the motor vehicle. Combined with the electrification of many forms of transport the combined effect on the electric bike market look promising.

Audi, which is owned by Volkswagen, is one of the largest car companies in the world, with the finances to conduct research into electric vehicle technology and bring a design successfully from the prototype to the display floor. Audi’s prototype electric bike, provisionally called the Wörthersee, has been making currents (that’s an attempt at a pun…) since it was unveiled. This is for many reasons – but the main one is that it is pushing the limit of what an electric bike can do and push beyond the traditional rider. The Audi ebike is a trick cycling bike, coming with two “wheelie modes,” automatic stabilization while tricks are being performend, and the capability of recording those tricks and uploading them to Facebook right from the bike! It’s this integration with software and social media that makes these bikes really interesting. They’ll connect the real world with the virtual world. It is those features that will likely sell this bike to the American sporstperson and convince them that an ebike is so much more that a bicycle with an electric motor.

Lightweight Carbon Fiber Frame

One of the drawbacks of electric bikes to date has been their weight. The battery pack has always been very heavy. This if fine when the battery is fully charged and assisting the bicyclist. But when the bike runs out of juice and the bicyclist needs to ride back home, it can be twice as difficult to reach home – especially if one has to do it by going up a significant grade. The Wörthersee incporporates not only a carbon fiber frame but also wheels of carbon-fiber-reinforced plastic (if you’re an anagram junkie, that’d be CFRP). The frame weighs 3.53 pounds, and the wheels weigh just 1.32 pounds. (Never fear, the frame is reinforced at load points, so it can bear a hefty amount of weight.) Add the battery to that and the total bike weighs only 46.3 pounds or 21 kg which is an amazing accomplishment in engineering.

Integrated & Interchangable Battery

In addition to being heavy, some electric bikes also looked rather clunky, as the large battery had to be strapped to a carrier on the rear of the bike or attached to the downtube. As the technology improves, ebike designers are coming up with ingenious new places for that battery – as well as the rest of the electronics necessary to run the bike. For the Wörthersee, the Li-ion battery pack and the computer to run it are located within the frame. The battery is easily removable, allowing the rider the choice to bring extra battery packs or ride naked. The battery will charge in about 2.5 hours from a 230 volt plug in.

The Motor

This electric bike is powered by a magnet synchronous motor. Basically it relies on magnets rather than the traditional coil. They are usually used to covert mechanical power to Electricity in large gas, steam, hydro and wind industrial turbines. The introduction of this technology show just how much engineering and design work went into this ebike. The motor has a peak output of 2.3 kW. The maximum torque delivered to the rear wheel is 250 Nm (that’d be Newton meters). The motor and battery is situated at the lowest point on the frame giving the bike a very low center of gravity. The rider controls the output of the motor using a traditional twist grip and can also control the ride modes through the on board computer.

Gears and the Brakes

The Wörthersee has nine gears, and shifting is ridiculously easy and fast with the nine-speed hydraulically actuated gear shift. Which was inspired by the R Tronic Clutch in the Audi R8. Bringing the bike to a stand still is no trouble with the fron and rear hydraulic disk brakes.

On Board Computer & Travel Modes

The Audi has five travel modes. The rider can choose between different balance between the motor and pedals.

  • Pedal-power only
  • Pedal assist
  • Electric only
  • Powered Wheelie mode
  • Balanced Wheelie” mode

‘Pure’ mode allows the rider to pedal the bike without electric assistance. ‘Pedelec’ mode assists the rider with the electric motor up to speeds of 80 kph (50 mph) for a distance of 50 – 70 kilometers (31 – 44 miles). ‘eGrip’ mode powers the electric motor using the standard twist grip found on a motorcycle. ‘Wheelie’ mode controls balance and power output of the electric motor to assist the rider in maintaining balance and control in the wheelie.

Speed

In pedelec mode (pedal assist) the bike can achieve a top speed of 80 kph or 50 mph, with a range of about 70 km or 44 miles on a single charge. In electric-only mode, the top speed is 31 mph.

Wheelies

The Audi Wörthersee is a sport bike, which means riders can pop wheelies and show off their skills. For beginning riders, the Power Wheelie mode allows the rider to adjust the angle of the rear wheel. The Balance Wheelie mode is for experienced riders. (Sounds like a Segway, doesn’t it?)

The Computer and Wi Fi

Everything about this bike is controlled by a computer, and it is also equipped with Wi Fi. In addition to riding, the bicyclist can actually record his ride via his or her smartphone, and upload footage to Facebook if so desired. There’s also an app that lets riders compete against each other with this video footage. The computer screen also shows the speed one is travelling, the distance one has travelled, and the remaining charge in the battery.

The Design

The bike looks slick. There are loads of unique and innovative  design elements on this bike. The Carbon Fiber weaved texture of the frame and wheels helps tie the whole design together. The red accents on the seat, brakes and pedals break up the black and grey of the Carbon nicely. Also, the white of the suspension and battery pack help lighten the design and draw the eye away from the battery. Compared to other traditional sport bikes the Audi is clearly the brain child of a sophisticated industrial design team. It has the right balance between performance and simplicity rarely seen in the over-the-top branding of most sport and mountain bikes.

Availability and Price

Currently the bike is just a concept. Based on the prototype’s materials and high-end components it’s likely to cost upwards of $20,000. This puts it our of reach of most consumers, but then again this is a performance bike. It sits in a new category that is a crossover between freestyle bicycle and motorcross. With all that in mind it’s well within the reach of performance riders who are used to paying upwards of $10,000 for performance mountain bikes. I’m certain Audi will broaden the appeal and lower the price point, as long as they don’t compromise on quality and performance which is unlikely. Either way I’m looking forward to see what the Audi design team comes up with.

Ottawa: New Rules for E-bikes” on the Capital Pathway Network

Ottawa: New Rules for E-bikes” on the Capital Pathway Network

This is a press release from Ottawa Start:

The general rules for ebikes on the Capital Pathway Network are:

1. Electric bikes that physically resemble conventional bikes are permitted on the NCC’s Capital Pathway Network.

2. All electric bikes, including scooter-type, are permitted on dedicated NCC bike lanes (as opposed to the multi-use recreational pathways, the Capital Pathway Network).

3. Scooter-type power-assisted bikes are prohibited on the NCC’s Capital Pathway Network as well as during Sunday Bikedays and Saturday Short Loops programs. Very often, the electric bike with a non-conventional appearance is much heavier than a conventional-type electric bicycle and therefore poses greater risks to safety in the event of a collision.

4. In Gatineau Park, all electric bikes are prohibited on the 90 kilometres of natural surface trails intended for hiking and mountain biking.

5. Rules for electric bikes do not apply to motorized mobility aids such as wheelchairs, three-wheel electric scooters and four-wheel electric scooters.

The NCC developed the new rules following consultations with the public, the City of Ottawa and Ville de Gatineau, local interest groups, public sector employees from other Canadian cities (Toronto, Vancouver and Montreal) as well as specialized cycling agencies.

In its Environmental Strategy, the NCC has committed to promoting alternative, ecological and sustainable modes of transportation. The NCC encourages active mobility by allowing the presence of electric bikes that require some muscular power on its pathways and promotes sustainable mobility by permitting the use of electric bikes that do not require muscular power on its bike lanes.

UK to study hydrogen fuel infrastructure

UK to study hydrogen fuel infrastructure

DESPITE years of being heralded as the ‘next big thing’ there’s still a healthy scepticism about battery-powered cars and bikes ever becoming truly viable as mainstream transport.

That’s largely down to their limited range, a result of heavy batteries that can’t hold a candle to the power density of good old fashioned petrol, and the lengthy charging times that make refuelling stops into overnight stays.

Hydrogen fuel cells, while still a long way from mass-production reality, arguably offer something of a solution. Using chemical reactions to turn hydrogen straight into water and electricity, they offer better power-to-weight performance than batteries and can be refuelled simply by adding more hydrogen. And now the Government has announced a project to investigate the nitty-gritty realities of turning the potential of hydrogen as a mainstream fuel into a reality.

What Speed is Best for an E-bike?

What Speed is Best for an E-bike?

Ed Benjamin of the Light Electric Vehicle Association spoke to BikeBiz.com about quotes from ExtraEnergy’s Hannes Neupert.

Ed Benjamin is the president and founder of the Light Electric Vehicle Association. He has written to BikeBiz.com to take to task their article featuring an interview with Hannes Neupert, founder of Germany’s ExtraEnergy e-vehicle consultancy. Neupert has now said he’s not opposed to ETRA’s lobbying to get e-bike rules in Europe changed, a measure soon to be voted upon by the EU.

Neupert’s original statement had said: “”The tendency of [ETRA] to ask for more and more power is not the real future. [And] when adding a power on demand throttle this will mean that you drop the pedals next and become a pure motorcycle. I have published in the latest ExtraEnergy magazine a proposal for future laws opposing to the current trend in the EU. Here I ask again for a combination of motor assist allowance in relationship to the muscle power input and a correlation between max assist speed supported by the electric enhancer and the muscle power input which is a new item.”

Ebiking the Swiss Alps

Ebiking the Swiss Alps

Tim Neville writes of his biking adventures for the New York Times:

THE road east out of Sörenberg rears up into a series of steep turns that climb the Glaubenbielen Pass, the high point of a road the Swiss Army punched through the Alps more than 60 years ago. Though the occasional car and bus make the journey to the top, these days much of the road belongs to cyclists.

On a cool afternoon in mid-July I was one of them. I hadn’t ridden much all season, yet something primordial kicked in when I spied another biker just ahead. His calf muscles were swollen like Salamanca hams, and he was stooped over the bars, sweat dripping onto the pavement.

Help Kickstart An Ebike Business in the US

Help Kickstart An Ebike Business in the US

Kkckstarter is a website where individuals who need financing post their projects, and those who want to help, donate via Paypal. If the project doesn’t get enough financing during the time period set up by the individual, no money is deducted from Paypal. It is only if the project is successful that money will be deducted from the account.

Best of all, you can pledge as little as $1, and every little bit will help.

Gabriel Wartofsky, an award-winning mobility designer, has launced a campaign called “Folding Electric Bike For Commuters” to begin US manufacturing of folding electric commuter bikes.

Here’s the website: http://www.kickstarter.com/projects/1585753369/folding-electric-bike-for-commuters

Wartofsky’s design, a lightweight, compact, intuitively folding electric bike, empowers commuters to get to the nearest bus stop or rail station, and, after commuting, to their office or school – without breaking a sweat, or losing the environmentally conscious benefits of traditional bike commuting.

Wartofsky, born and raised in Washington, DC, grew up in a family with no automobile. His mother earned cult notoriety in the Chevy Chase, DC area and recognition in the Washington Post as “the bike lady”. His ecological mobility solutions have won multiple awards and publishings, including the Michelin Challenge Design Competition, Interior Motives and Dura Design Awards. Wartofsky also has work experience as a design consultant to companies that include BMW Design Works, Nissan, Bike Nation and Big Blue Bus of Santa Monica.

“I want people to again experience the joys of the bicycle my mother enjoyed for most of her life,” said Wartofsky. “My challenge was to design a bike that will enable commuters to reacquaint themselves with the hidden magic that surrounds daily travel. An easy, fun way to get around.”

Kickstarter, a funding program for designers of creative projects to reach out to potential supporters via the Internet, is the perfect platform for Wartofsky to highlight his commuting solution. The hands-on nature of Kickstarter allows those interested in helping shape the future of commuting to directly participate and collaborate in the final design and production decisions for the electric bike.

Everyone who backs the project receives something – from getting their name on Gabriel’s newly launched company’s web site for only a $1 pledge, participating in crowd-sourcing, receiving a t-shirt they helped design, going to Gabriel’s star-studded launch party in LA, or even purchasing the folding e-bike at less than the price of top folding bikes without electric assist.

“The best part of Kickstarter is that it allows everyone who wants to, to be involved” said Wartofsky. “I’ve been working on prototypes for this bike for a long time, and I need help in taking my final prototype into full production.”

The funds raised during Wartofsky’s Kickstarter campaign will be applied to launch the U.S. production of his folding e-bike. Product launch and his first production run are slated for Q1 2012.

DIY: Solar Powered E-Bike

DIY: Solar Powered E-Bike

Since 2008, home inventor Terry Hope has been working on a pair of solar powered electric vehicles in Canada since 2008. He started on his first solar vehicle, called The KPV, after needing to find a way to bring a collapsible electric scooter on board a sailing vessel off the British Columbia shore.

Weighing around 50 pounds, the KPV features two options for recharging its LiFePO4 main battery pack. One option is connecting to mains electricity via the onboard AC-DC power supply, while the other is an emissions free method making use of 14 6″x6″ mono crystalline solar cells wired in a series, the output of which is controlled via a group of dpdt rocker switches.

Australian College Students Invent the Di-Wheel

Australian College Students Invent the Di-Wheel

EDWARD is electric vehicle – the two wheels arranged side by side rather than one behind the other. The motors in the wheels are controlled by a joystick, and this means that, by spinning them in opposite directions, riders can quite literally turn on a dime (or over a dime, should one be put beneath the machine). The rider can also lock the wheels to the chair with a handbrake, which will spin the rider along with the wheels for some hot, nausea-inducing action.

Columbia, SC Embraces Electric Bikes

COLUMBIA, S.C. — Officials in Columbia have broken ground on a new, six-story downtown parking garage that also features charging stations for electric vehicles, bicycle racks and a bus shelter.

The State newspaper reported Tuesday that Columbia Mayor Steve Benjamin said he hopes the $11.3 million garage is a catalyst for business and residential development in the city’s core. The first floor of the garage has space set aside for shops and other retail establishments.

The new garage is located about a half-block from the Mast General Store, which opened on the city’s Main Street last month.

Columbia’s parking services director John David Spade says the garage is the third built through a 2005 revenue bond issue and that parking revenues, not taxes, are being used for its construction.

Hundred Watt Hybrid sets off on Eco Tour across America

Hundred Watt Hybrid sets off on Eco Tour across America

Nash Hoover already had some build experience from converting an old golf cart into an off-roader named the Swamp Crawler a few years back. Recently, he set about designing and building a lightweight vehicle capable of taking his son and himself on a 4,500-mile (7,242 km) journey from Yorktown, Virginia to Portland, Oregon.

Hoover and son came up with a four-wheeled, side-by-side two-seater, human-electric hybrid vehicle with a fast-turning, stand-alone EcoSpeed brushless electric motor connected to the vehicle’s existing chain drives, and a roll bar structure to the rear of the vehicle to afford some crash protection for the occupants.

New Battery Design Will Make Them “Refillable”

New Battery Design Will Make Them “Refillable”

Battery technology under development at MIT could someday make recharging batteries as quick and easy as a trip to the gas station.

The new battery design, known as semi-solid flow cells, turns the chemistry of traditional lithium-ion batteries into quicksand-like tiny particles. The resultant slime has an extremely high energy density and is inexpensive to manufacture.

That “fuel” offers another advantage: it can be refilled as well as recharged thanks to the new battery’s aqueous-flow structure. Instead of plugging in to recharge, you could simply refill the depleted liquid at a refueling station.

How To Retrieve Your Electric Bike

How To Retrieve Your Electric Bike

This story is from the Global Times, and took place in Beijing:
A Beijing man whose electric bike was stolen on October 24 got it back the next day after going online to buy a new one and finding his for sale.
The man, surnamed Ye, said that after the bike was stolen, he left a message to an online seller of electric bikes and on October 25 received a reply that one was available.

Ye then asked for a photo of the bike and was shocked when he received it. It appeared to be his. “I couldn’t believe it,” he said. “I wondered if it was a coincidence but after I learned more details, I knew it was mine.”

He bargained with the seller, surnamed Ye, and agreed on 1,000-yuan ($150) and a place to close the deal.

Later that day, Ye arrived to meet the seller, while at the same time a coworker of his had called police to tell them the story. They arrived also and caught thief and returned the bike to Ye.
