BMW Motorrad Develops C1-E Electric Study as Contribution to eSUM

BMW Motorrad has developed an electric study vehicle, the C1-E, as a contribution to the European safety project eSUM. This study unit is based on the concept of the BMW C1, and is characterized by a very high level of active and passive safety.
The electric motor employed in the study has been designed for city use and is based on components by the company Vectrix. The motor obtains its power from a lithium-ion battery and thus possesses sufficient power for mastering most inner-city traffic riding. Alternatively the vehicle could also be equipped with an efficient, low-emissions internal combustion engine.
The safety features of the C1-E have been taken from the former BMW C1 and further enhanced. (The C1 is the only motorized single-track vehicle to be exempt from mandatory helmet wearing in almost all European countries.)
A safety cell with a conspicuous roll-over bar dynamically spans the rider seat in combination with the energy-absorbing impact element at the nose end. A further special point is that the C1-E rider wears a seat-belt. In the study this safety feature is highlighted by red belts and belt buckles.
The C1-E BMW Motorrad study is to remain the only model of its kind. Series production is currently not planned. Nevertheless, findings from the project will find their way into other future developments in the field of single-track vehicles, said BMW.
eSUM. eSUM stands for European Safer Urban Motorcycling. It is a cooperation project between major urban European motorcycling centres and motorcycle manufacturers. The cities currently involved in the project include Paris, Rome, Barcelona and London and the manufacturers are BMW and Piaggio.
The advantage of two-wheeled transportation is that it offers a great opportunity for improving the flow of traffic in urban locations, and can be more environmentally friendly. However, the vast majority of accidents occur in urban traffic, in areas where 80% of the population live.
The idea behind eSum is to look into ways of countering this trend. The joint goal is the identification, development, and practical demonstration of measures which are able to guarantee safe motorcycle and motor-scooter transport in the inner-city traffic of the future.
One of BMW Motorrad’s major concerns over the last twenty years has been the improvement of motorcycle safety. This was amply demonstrated by the consistent strategy which has led to the Motorrad ABS and continued with its long-term ongoing development. On 31 August, the 1,000,000th BMW motorcycle with Integral ABS, a BMW K 1300 R, left the production line in Berlin-Spandau.
Since 2005, a series of further active safety features have been developed to enhance the safety BMW motorcycles still further: RDC Tire Pressure Control, ASC Anti-Slip Control, the new Race ABS and the DTC Traction Control incorporated in the new BMW S 1000 RR, as well as a range of BMW Motorrad rider equipment.
BMW Motorrad is also conducting research into forward-looking rider assistance systems designed to increased road safety, as part of the ConnectedRide project. Features being looked at include cross-traffic and traffic-light assistance as well as a warning system for impending poor weather, road obstacles, an approaching emergency vehicle, or sudden braking manoeuvres.
This vehicle should be fitted with a range extender build from the tiniest model airplane engine. There are far more than enough electronics available at low enough costs to make it electric start from an almost depleted battery or it could have its own spare starting battery. Fifty cents will buy the computer processor needed. ..HG..

Your greatly underestimating how heavy that thing is.

I suppose something like this with an Adrenalin drip might find some buyers.

@Henry
Why would you say this needs a range extender? There's no info in this article about how much range this has to start with so there's no way of saying it doesn't have enough range to meet your needs.

I ride a scooter and on a typical 150cc scooter very suitable for urban riding (top speed 60 mph) the motor is 9 HP. Most cycle and scooter motors are primitive compared to a car, for example fuel injection is still rare. Most cycle riders think they're saving the planet getting 70 MPG but if you do the math based on weight its comparable to a car getting 5 to 10 MPG.
Just from experience I'm not comfortable with the idea of wearing a seatbelt on a scooter but who am I to say?
Never been in a cycle accident and never seen one.
