Shavit – Electric adjusable superbike
Shavit is basiclay a road sport bike (superbike), with an adjustable riding position system, which allows it to turn into an everyday tourer/urban motorcycle, without sacrificing it`s basic sport bike character, by changing the riding position geometry and basic bike ergonomy.
it hold an electric motor and battery pack, and in contrast of those “sterile” components, it`s all built around and a “mechanical-technical-all out” chasis components, to create a sharp and agressive superbike icon, that would talk to superbike riders heart, which are rather conservative by taste and acceptance of new technologies which chage the formilliar visualisations of bikes.
Everyday handling with superbikes is almost impossible, mostly due to
the racing track oriented aerodinamic and ergonomic riding position. But in the real world, when people buy the race replicas, most of the usage accours in the public road, and even more, in the urban environment of home to work rides.
The problematic ergonomic of the everyday handling is due to 2 main ingridiants on the bike:first, the footpegs height, which sqeezes your legs way up in order to add more ground clearance while cornering.second, and even more important, the low handlebars which are loading the weight on the front of the bike for better handling in high speed and power transition, and also creating better aerodinamic position for those high speeds. those features are basicly “edgy” track orientated, and have no place in the everyday handling. On the contrary, they create an uncomfortable package which was designed into a different niche, and was addopted in a different environment in order to enjoy it`s other aspects: engine power, firmness, apperance-styling, and most important – talking to the riders heart and character. defining the man riding, creating a different visual, status and impact.
the main challenge was to create a package which can transform, with the added value of both aspects, without losing it`s basic nature and character. and without compromising on the ingredients riders look for in their dream bike.
As a superbike rider myself i struggle with the problem of an everyday commuting with the bike.
i saw the solutions in front of me, and as a conceptual project i could give the answers to this problem, in a matter which today`s technology, or at least the upcoming year`s technology, could definitely mechanically solve.
Other thing that came along were defining the engine and chassis specs.
Selecting an electric engine platform gave me a lot of freedom in the design process and allowed me to break some conceptions in the motorcycle design scheme, like the lack of fuel tank, of the battery packaging which is used as the connection between two parts of the motorcycle chassis.
the
also, most of the final form was after a process of aerodynamic research in the motorcycle history.
and finally, the design was stitched on a human figure, and built around it, instead of first sketching and than put the rider in place.
The process starting point was to built wooden frames in 1:1 size, which gave me the entire movement i wanted to create on the bike`s components: handlebars. seat height and foot pegs.
after i found the correct measurements i created a 1:1 wood and cardboard mockup with tires and basic shape, and this was the real starting point of the design.
every sketch was tested roughly on the 1:1 model. was by sitting on it i could get the feel in it worked for me or not.
basically, i designed a bike for me. for my needs, for my world.
though it seems very individual, other riders from my niche would feel the same on it.
the individuality on bikes comes from the connection with the machine, a connection i worked so hard to achieve before entering the styling issue, which then put it on a different level of connection with the rider.
The value of the project is the comfortable opportunity which did not exist before.
the understanding that human use it, for their need sometimes and not just for their wants.
i wanted to create a superbike which you can live with, which wont punish the rider.
which can make the connection between it and the rider stronger. more understanding.
using the electric engine i can create a platform which would be more understanding in todays matters, environmentally, technologically, sustainable. this platform is not a “by the way” decision, it`s probably the only chance of this whole bike as a concept to exist. it allows freedom in design, in bike`s architecture, in visualisation, in style.
in cars for example, you can buy a Porsche, and when you drive it you sit and drive.
maybe little less comfortable than big saloon cars. maybe a bit more stiff. but still you get a great driving experience on public roads.
there is not 1 sportsbike in the world which you can say the same about.
this is where i want to be.
Shavit showed a complete design process – one of the best we have seen. From ideation, through sketching, then mock ups, then movement studies, then prototyping, the Shavit project was a clear and well developed entry.
The “pivot” or “adjustable” innovation on the bike is a clearly articulated and compelling need, but a challenging one to solve. Shavit demonstrated subtlety and thought in how to make this work. Well done here.
The aesthetics of this design were consistent and well articulated. The 4 judges were from very different backgrounds but unanimous in liking the design aesthetics.
The movement studies showed a feasible approach to the adjustable idea Additionally, the usage of standard equipment and other well-known engineering set-ups (e.g. front forks, rear drive, spoked wheels, hand throttle, etc) made this appear even more feasible.
BRAVO!
