Innovative Concepts at Intermot

Intermot Cologne, the world’s largest motorcycle and scooter show, was held from October 8-12, 2008. 1,057 exhibitors from 37 countries displayed almost eight halls of gasoline-powered motorcycles, scooters, quads, clothing and accessories alongside with a couple of electric 2-wheelers.

People in Europe are discovering over 125cc scooters to replace their second car. Booming sales in this segment, combined with climate change and raising gasoline prices created an atmosphere in which electric vehicles, such as the Vectrix maxi-scooter, caught a lot of attention.

Innovation Cafe in hall 4.1
Quite some square meters of hall 4.1 were dedicated to electric mobility. Here, the Innovation Cafe showed products and projects with alternative propulsion technologies. Among them were interesting electric vehicle concepts, such as the eROCKIT electric motorbike from Berlin, university projects with innovative designs, an electric motor cross bike called eKRAD with up to 2 hours battery capacity. It will also be produced in modified versions for super-moto and enduro sports.

E-Bike track with solar charging station
Behind hall 7 there was an outdoor track for electric vehicles. From all the other outdoor tracks, where spectacular motorcycle and quad stunts, super moto and other races were shown, the electric vehicle track still stood out thanks to the large Solon solar charging station. Solon AG is one of Europe’s largest producers of solar modules and photovoltaic systems. The solar charging station SOLON Mover consists of a 50 square meter photovoltaic station to produce energy, a system to store the energy, which is independent from electricity networks, and charging outlets for electric vehicles. In cooperation with Vectrix of USA, the SOLON Mover allows electric mobility to be 100% emission free.

Competitive electric scooters
For those who had a motorcycle drivers’ license, the Vectrix maxi-scooter was available for test riding. The acceleration of the comfortable two-wheeler is spectacular. It reaches a speed of 80km/h in only 6.8 seconds and goes as fas as 100km/h top speed. The multi-function throttle serves as accelerator and rear gear. A motor brake recuperates energy and recharges the battery. When the battery is empty it recharges by 80% in 2.5 hours at the power-outlet. The user just needs to pull out the charging cable from the luggage compartment connect it to the right adapter (depending on the country) and plug it into the power-outlet. On a full charge the Vectrix scooter rides 50-100 km depending on the riding style and conditions. The saving on gasoline and operation cost make up for the high purchase price of 9,900 Euros.

Besides the Vectrix, and some other electric scooters, the iO Florenz with lithium-ferrum-phosphate battery and a 3,500watt motor was available for test ride without a motorcycle license and made a good impression on the curvaceous track.

The e-max, which combines German engineering and Italian design is a competitive alternative to a gasoline 50cc scooter. It comes in two versions at 3,000 – 3,300 Euros. The speed is limited to 45km/h, so it can be driven with a car driver’s license. The range varies between 45-60km (90s model) and 70-90 km (110s model).

Between electric bicycle and motorcycle

The combination of electric bicycle and scooter / motorcycle characteristics leads to an individual vehicle category, which does not have to directly compare to the price, performance, and design of gasoline two-wheelers. It is a new species on the road. Intermot showed two interesting concepts that are somewhere between e-bike and e-scooter:

The eROCKIT combines bicycle and motorbike optics and function. It rides like a bicycle––just a lot faster. The refreshing effect of cycling comes together with the feeling of speed and driving dynamics of a motorcycle. The solid, TUV approved man-machine hybrid motorcycle is equipped with an 8kw motor and lithium-nano-phosphate batteries. A generator, which records the rotation of the crank drive, has a double function: it sends the signal of human input to the controller and, at the same time, recuperates the pedaling energy. This energy is used to permanently recharge the battery. The faster you pedal, the faster the DC motor turns. The extremely high torque of the motor is available from the first second and allows a spectacular acceleration. eROCKIT rocks you up to 80 km/h for as far as 60-80km on one charge depending on riding style and conditions.

The first exclusive series of 10 vehicles will go into production next year. Components from external suppliers exclusively involve high-end motorcycle parts, such as fork, suspension, wheels and brakes. The other parts are manufactured by ErockIT GmbH in Berlin and range from handmade carbon parts to aluminum components of the company’s own CNC cutting. Every single unit will be tested under toughest conditions before it sells for 28,900 Euros.

ErockIT GmbH was founded in 2005 by Stefan Gulas from Austria and employs nine people today. Four series of prototypes have been produced and tested during the last four years. Riding one of the first prototypes already felt as if some kind of supernatural powers let you fly.

French manufacturer of trial motorbikes, Scorpa, founded an electric vehicle division under the name SEV. The ETricks bike, which was shown at Intermot, is SEV’s first prototype. It involves two lithium batteries, one is integrated into the main frame, the other one can be attached next to the fixed battery. ETricks is a bicycle type vehicle that resembles a motorbike in many details. It is supposed to go into production in April 2009 with type approval. After only eight months of development this seems a very ambitious goal. The price is already set: once ETricks is in production it will sell for 2,000-2,400 Euros with either lead or lithium battery, said a company representative.

University Projects

Honda Oree
Two industrial design students of the University of Offenbach in Germany, Niko Albertus and Andre Look, presented their study Honda Oree in the Innovation Café at Intermot. They wanted to create an electric motorcycle that would perfectly cope with sharp turns on country roads. The study did not only concentrate on the design and feeling of such a vehicle but also involved technical considerations how to put the concept into reality. The students received professional advice from Honda before they began to work on Oree.

A 70kw electric motor is supposed to provide an extremely high torque and accelerate the 150kg Oree to a maximum speed of 190km/h. Two separate battery modules serve as energy source. They are located in the front spoiler where they keep the center of gravity low. The designers also envisioned using additional batteries to extend the range––at a heavier weight, of course.

So far the study comes as a small-size model. How Oree will develop in the future, depends on the interest of industry and media.

Carbon ultralight bike hmk 561

The carbon ultralight bike hmk 561 is a project of the aircraft construction department of the University of Stuttgart in Germany. The model that was exhibited at Intermot, demonstrated that carbon fiber can take many more tasks than just static function. The special layer structure of the carbon fiber makes it possible to conduct energy through the frame and store it. There are electric motors integrated in the front and rear swing arms. They transmit the power directly to the rims. During speed reduction or waiting at traffic lights or parking, the energy is regained and serves to feed the board devices.
