Zerotracer motorcycle throws down gauntlet to electric cars

The Zerotracer
The Zerotracer

The Zero Race will see contestants dash around the globe in 80 days in zero emission, electric powered vehicles... and one of the most distinctive entries is the Zerotracer. Designed by a group of engineers from Winterthur, Switzerland, the Zerotracer is an electric motorcycle that encloses its two occupants in a Kevlar shell and is capable of a top speed of 250 km/h (155 mph) and a range of 350 km (217 miles) on a single charge.
The vehicle is based on a MonoTracer body but replaces that vehicle’s 4-cylinder in-line BMW K-engine with a battery-powered electric motor that provides 135 kW/183Hp to propel the Zerotracer from 0-100 km/h in 4.5 seconds. Without passengers the body of the vehicle weighs less than 80kg (176-lbs) and the 18 kWh, 400V battery pack can be fully charged in two hours, while a quick charge can charge the battery pack to 80 percent capacity in less than 30 minutes.
Since the driver and passenger are enclosed in the vehicle’s Kevlar composite outer shell and can’t use their legs to stay upright when the Zerotracer isn’t moving the vehicle uses a pair of retractable wheels to stabilize itself when stationary. When retracted these wheels protrude from the side of the cabin to act as a “knee” to skim the road when cornering at high speeds.
Inside the cabin the occupants are treated to an almost noiseless ride thanks to the silent electric motor, unless of course they are listening to the Zerotracer’s stereo system. The vehicle also boasts a heating system and two bucket seats from which to enjoy the panoramic 250 degree-plus views provided by the plexiglass windshield.
The rules of the Zero Race state that the race teams must produce their own electricity using renewable sources such as solar, wind, wave and/or geothermal. This electricity must be then fed into the grid system in the home country of each team to offset the electricity used by the vehicles during the race. Taking care of this aspect is the team’s main sponsor, Oerlikon Solar, which will generate electricity from thin-silicon solar panels at the company’s headquarters in Trubbach, Switzerland.
With its aerodynamic design and impressive performance statistics the Zerotracerstands to be a real contender to take out the honors when the Zero Race kicks off in Geneva, Switzerland, on August 15. 2010. We’ll take a look at some of its competitors in the coming weeks.

Sanyo and Suzuki have announced a collaborative project resulting in the development of an electric drive system for an prototype scooter named e-Let's

    Sanyo and Suzuki have announced a collaborative project resulting in the development of an electric drive system for an prototype scooter named e-Let's. About the same weight as the petrol scooter it was based on, the prototype has a claimed range of 18.6 miles and its battery pack can be charged using a household outlet. The scooter is currently undergoing on-road trials leading to possible commercialization.
    Based on a petrol-engined model called the Let's4 basket, the e-Let's features an in-wheel electric motor to the rear with regenerative braking, a dedicated charger and battery system, a "high efficiency control circuit" and a Li-ion battery pack. The developers have managed to keep the new prototype at about the same weight (74kg) as its petrol predecessor.
    The e-Let's scooter is charged from a 100V household outlet and a single charge is said to take about four hours and should be good for a journey of around 18.6 miles (30km), not exactly ground-breaking but sufficient for most inner city journeys. The prototype is said to offer the kind of "smooth acceleration, nimble performance, low noise, low vibration" that is making electric scooters an attractive short commute option.
    Last week, Suzuki began testing the prototype on public roads in Japan and plans to use the data gathered to create a production model. The road trials will also be conducted as part of the Hamamatsu Social Experiment Project on Next-Generation Eco-Cars announced in May.

The PG-Bikes BlackTrail - world's fastest ebike!

The PG-Bikes BlackTrail - world's fastest ebike!
The PG-Bikes BlackTrail - world's fastest ebike!
It’s no secret that as gas prices soar and battery technology evolves, electric bikes are fast becoming the next big two-wheeled thing. That trend is clearly evidenced by the strong showing ebikes are making at this year’s Eurobike trade show, currently taking place in Friedrichshafen, Germany. Over the next several days, we’ll be showing you a few examples that we’ve spotted at the show, but to start things off... well, let’s kick out the jams and go with the “Oh come on, you can’t be serious” ebike. It called the BlackTrail, and with a top speed of 100 km/h (62 mph), it’s officially the world’s fastest commercially-available electric bicycle – and probably the most awesome-looking, to boot.
The BlackTrail is the result of a collaboration between two German companies, namely PG-Bikes and carbon fiber products developer UBC, which also designs parts for Formula 1 race cars and Porsche Carrera GTs. The bike itself is striking – it has the classic styling of a 1930s motorcycle (complete with brown leather saddle and battery cover), but with the sharp angles and undisguised carbon fiber of a rocket bike.
The non-human-generated speed is supplied by a 1.2 kW CM48 V hybrid motor, powered by a 48-volt lithium-ion battery. It charges up to 80 percent in 30 minutes, and up to 100 percent in 150. At its top speed, the bike has a range of 40-60 kilometers (25-37 miles). At its cruising speed of 30-50 km/h (19-31 mph), that range extends to 160-200 kilometers (99-124 miles). No acceleration specs were provided.
Besides carbon fiber, its body is composed of high-alloyed aluminum (“used by NASA”), titanium and magnesium, for a total vehicle weight of 19.8 kg. (43.65 lbs.)
Is it cheap? Nope. If you wish to purchase one of the 667 BlackTrails that will ever be built, be prepared to part with approximately US$75,460. You could certainly get a full-on electric motorcycle for much less money, but... with a huge ticket item like this, bang for the buck is hardly the point.

    Why would I pay $75K for a bicycle? That Oregon based company has a motorcycle, with a suspension for less than $20K, does a sustained 100mph.

    I've been riding my ebike every chance I get, it is unbelievably fun. My commute is significantly faster and actually rewarding in so many ways. I can't even begin to explain how incredible it is to blow through standstill traffic with the speed of a professional athlete while getting around 1000 mpg equivalent. Also, I get to park at the door and have a bunch of money suddenly not being spent on car stuff. Srsly, cars are for suckers, just like this absurdly overpriced bike.

    Gad, that thing is FUGLY.
    At first glance I thought it was a photo of a motorcycle from the turn of the LAST century.

    This is a bad joke. Going 62mph without suspension is not doable as the rider would get thrown off on normal streets. Next 1.2kw isn't enough to push a bike that fast without aero body. It would take 7-10kw to do that.
    In the US it's not a bike but a MC, pedals or not.
    Ebikes and MC's are a great idea but this one isn't. Plus unlikely to be the fastest Ebike under their difinition either.

    The speed record was 64 mph on a 3-wheel human powered streaminer from the early 1980s (Vector). That record held for many many years. Now it is up over 80 mph on a 2-wheel streamliner. I don't know if spending $75K and finding about faster bicycles will make customers very happy.

    Makes me wonder if they actually did market research before coming up with the production limit of 667. For what they are offering at that ridiculous price point, I have the feeling that they will be waaaaay overstocked!

    I have done 130Kmh on a bicycle - down a HUGE steep and long hill, towing a trailer full of heavy stuff......
    Quite good actually.
    For the people who shit can first and think nothing later......
    1. If you are going to do much more than 20 - 30Kmh.... and way up too 100 kmh, dump the velcro and wear more and more heavy duty stuff like joint pads, gloves and leathers.
    2. Avoid surfaces that induce excessive vertical accelerations.
    And - Or:
    3. Buy a motorbike.

    Very clean looking, but as far as being new or "the fastest"....No
    I made one of these about 4 years ago (60mph ebike)... Terrible idea. Recently i made an electric moped with a 65mph top speed and a 40 mile range. Great suspension, full lights and all, much better idea then this death machine.

    Yes 'jerryd', you are right about it needing a lot more KW to do 100km/h (62mph) but you CAN do it without suspension and without getting bucked off...it all depends on the road condition... (for a real world motorized bicycle check this out: bikemoto.wordpress.com)

    Magic powder can make electric bikes run on urine :)

    Published: Thursday, Oct 7, 2010, 19:42 IST
    Place: Washington, DC | Agency: ANI


    Pedago offers several models of electric bicycles.


    Electric bikes may soon be able to go up to 60 miles without any pedalling, thanks to a new fuel cell system by the company SiGNa Chemistry, which uses a magic powder that nullifies the danger of having hydrogen stored next to your nether regions and can work even by urine. For a long time, that was one of the main reasons why electric bikes didn't all have fuel cells. But, the range extending system that SiGNa developed uses a sandy metal powder called sodium silicide, which creates hydrogen gas as soon as water hits it, reports Discovery News. According to the company, sodium silicide is "a safe, air-stable reactive metal powder" that produces hydrogen at about half the pressure of a soda can. While it’s not clear on precisely how it's made, but it looks like the powder can be formed by absorbing sodium in porous silicon dioxide, or reacting sodium directly with elemental silicon. After the powder in the cartridge creates hydrogen gas, the byproducts are sodium silicate, which is actually pretty useful stuff, and water vapour. Once all the powder is spent, the cartridge containing it can be reused. With SiGNa's fuel cell system, electric bikes should be able to go up to 60 miles without any pedalling, as opposed to the 20-mile limit for most existing e-bikes. A spent cartridge can be swapped out for a new one with no need for recharging. Unlike lithium-ion battery energy density, which is around 65 Watt-hours per kilogram, the cartridge has an energy density of more than 1,000 Watt-hours per kilogram, according to a press release published by Wired's Gadget Lab. The cartridge doesn't need special water, either -- even urine will be enough to make it work. You know, in case something goes horribly wrong on that ride. Recently the company worked with the electric bike manufacturer Pedego to demonstrate the range extender at the Interbike International Trade Expo in Las Vegas. SiGNa describes the £1.5 cartridges as "inexpensive," but didn't give a price. Currently the company is taking pre-orders for the fuel cells, so it will likely be a while yet before they make their way into any vehicle.

    Paris Motor Show: Scooters And Bikes Steal The Spotlight

    2010_smart_escooter_1

    The city of Paris is filled not only with cars, but even more so motorcycles, scooters and bicycles. So it wasn’t much surprise that we’d see a few on display at the Paris Motor Show. What is interesting is how some manufacturers are looking at bikes and scooters as an entry point into an automotive brand. Smart revealed this exact strategy during their press conference and following the reveal of the eScooter and eBike prototypes. Part of the rationale behind introducing these two products is to offer more affordable transportation alternatives to a car. Both in Europe and the US, insurance for young drivers costs a lot. Smart is looking at the eBike and eScooter as either steps up to car ownership or a more space conscious solution to urban mobility.

    2010_smart_ebike_1

    Smart describes the eBike as a muscle powered – electric hybrid. As a rider pedals, electricity is generated and  stored in a lithium-ion battery pack located just above the crankcase.  Power is then transferred to a 250 watt motor in the rear hub of the bicycle giving the rider a boost on flat roads and making climbing hills easier. Smart considers the eBike the first entry point into the brand because no drivers license is need to operate it. The top speed generated by the motor is limited to 15.5 mph keeping the bike from being classified as a scooter. When braking, the rear hub actually recaptures electricity and sends it back to the battery.

    2010_smart_ebike_2

    The eBike was designed to appear “uncluttered”. The safety cell frame and body panels of the Smart fortwo car became the inspiration for the design of the eBike frame. For nighttime riding, the eBike has integrated front and rear LED safety lighting. The small headlight is attached to the handlebars instead of the frame so when a rider turns, their direction of travel is illuminated.

    2010_smart_ebike_3

    Smart designed both the eBike and eScooter to have smartphone integration. For the eBike, the owners smartphone becomes the “starter” and the immobiliser. The bike will only work when the owners phone is inserted into the cradle on the handlebars and the motor ‘locks’ when the phone is removed. The phone also serves as an interface for a speedometer, and heart rate meter.

    2010_smart_escooter_2

    The Smart eScooter is the next step up from the eBike. The zero-emission electric drive scooter is powered by a 4 kW disc shaped motor in the rear wheel. Smart says the eScooter can attain a top speed of 28 mph and has a range of 62 miles on a full charge. The eScooter can be plugged into a standard household socket via a charging cord located beneath the emblem on the front of the scooter. A full charge takes three to five hours. Smart has integrated some interesting safety features into the eScooter. It is equipped with electronic front and rear ABS and the brakes are activated with a single twist of the hand grip. Like the eBike, energy is recovered during braking and sent back to the battery. The eScooter also gathers electricity from a section of solar panels located on the front fascia. The scooter employs more advanced smartphone integration and has features like a range and battery charge display, navigation, and ‘parking GPS’ which sends a homing beacon to the owners smartphone so they remember where the scooter is parked.

    2010_mini_scooter_e_1

    Mini debuted the Scooter E Concept in two variations at the Paris Motor Show. In contrast to the model from Smart, the Scooter E’s showed the potential for how a scooter could be customized to more reflect the needs and personality of the owner. The drive system of the Mini is similar to the Smart, standard plug-in charging, lithium-ion batteries, and an electric motor in the rear hub.

    2010_mini_scooter_e_2

    The Scooter E integrates a lot of Mini design ques. The headlight is very similar to the MINI Countryman’s. And the tail lights resemble scaled down versions from the Mini Cooper.

    2010_mini_scooter_e_4

    Even interior design elements from Mini road cars have found their way into the design of the scooter. The handlebar gauge is similar to the large center mounted speedometer of the road cars. Another carry over is the ‘center rail’ on which accessories like small storage cases and bags can be attached.

    2010_mini_scooter_e_3

    The Scooter E is activated via a smartphone which also serves as a display for scooter controls and navigation. The plastic panel in the center of the speedometer shown above opens and a phone can be inserted horizontally.

    2010_mini_scooter_e_5

    With a change in body color and materials, Mini demonstrated how the Scooter E can have a unique and distinctive appearance.
