BMW DC 04: A Revolution in Electric Motorcycles
BMW ELECTRIC MOTORCYCLES: LOSSES AND PATENTS
BMW has introduced several electric motorcycles since 2015. Functional studies, concepts and test vehicles. Bayerische Motoren Werke even patented the brand's typical boxer engine design for the cooling system of an electric motor. MOTORRAD shows the latest developments.
BMW Motorrad recently registered and protected 11 new names for future models. After the launch of the CE models, dedicated to electric scooters and urban mobility concepts such as the BMW CE 02, the company is now focusing its efforts on larger electric motorcycles identified by the acronym "DC". The new names include DC 01, DC 02, DC 03, DC 04, DC 05, DC 06, DC 07, DC 08 and DC 09, intended for motorcycles, parts and accessories. In June 2019, BMW unveiled the Vision DC Roadster concept, which introduced the electric motorcycle line, with "DC" standing for "direct current". There are currently no aftermarket accessories available for these new BMW electric motorcycles.
Modular monocoque chassis with integrated battery
At the end of December 2023, a new international patent application was published by BMW for a modular monocoque chassis intended for electric motorcycles. This frame includes a central battery compartment, made of carbon fiber-reinforced composite plastic, such as Kevlar. There is also the possibility of creating hybrid constructions using light metals such as aluminum or titanium, especially in critical areas such as the steering head and swingarm support. The modular design offers the flexibility to tailor the wheel suspension to the specific model, reducing costs and simplifying production thanks to fewer components.
The DC 04 could be BMW's first electric motorcycle?
In March 2023, patent drawings surfaced that may refer to the DC 04, BMW's first electric motorcycle. This new model appears to be based on the BMW G 310 R, the combustion engine version of which delivers 34 hp (25 kW). The BMW DC 04 is likely to use components from the CE 04 electric scooter, already available from 2022, but with a reorganization of the battery pack and motor to adapt to motorcycle use. The electric motor would transfer power to the rear wheel through a system of bevel gears and a toothed belt, with a deviation of 90 degrees.
BMW Vision DC Roadster and the electric boxer engine
The Vision DC Roadster concept, introduced in 2019, attracted attention for its design inspired by the classic two-cylinder boxer engine, with a cooling system located in the indicated "cylinders". A patent application from June 2022 suggests that BMW is exploring this direction, featuring cooling cylinders mounted directly on the drive, with specific functions such as heat exchange or passive cooling of electronic components. However, these patents are still in their infancy, and do not allow definitive conclusions to be drawn.
BMW E-Power Roadster Concept 100 kW
In December 2019, BMW presented the E-Power Roadster Concept, an electric motorcycle less visionary in design than the Vision DC Roadster, but with a power of 100 kW (136 HP) and a total weight of approximately 300 kg. Despite this, BMW has not yet completed the development of a high-performance electric motorcycle ready for series production.However, the DC range numbered 01 to 09 suggests that several models are in the pipeline, which could range from the Vision DC Roadster to the E-Power Roadster Concept.
E-Roadster, E-Tourer, E-Adventure?
The widespread registration of names for new models appears to indicate a long-term planning strategy on the part of BMW, thus protecting the names and technologies from potential claims by other manufacturers. In the future, we are likely to see models such as e-roadster, e-tourer and e-adventure bike. Meanwhile, the image gallery offers a look at previous developments of BMW electric motorcycles.
BMW CE 04 and CE 02 for urban mobility
The currently available BMW CE 04 was launched in spring 2022 as the successor to the 2014 BMW C Evolution. From 2024, it will be joined by the BMW CE 02, a "125 electric" model with an output of 11 kW ( 15 CV), accessible with a class A1 license from 16 years of age or with the B196 extension of the car licence. Both models are intended for urban mobility, ideal for short trips in metropolitan areas.
Production of BMW electric models at TVS in India
BMW is collaborating with Indian partner TVS on the development of future electric models. TVS already produces the G 310 models for BMW, and in 2023 it started production of the BMW CE 02, the first electric model in the range.
The BMW DC 04 aims to be a significant turning point in the world of electric motorcycles. The famous German brand, known for its boxer engines, is taking a step towards a greener and more sustainable future with this revolutionary motorcycle. But what makes the BMW DC 04 so special compared to the traditional electric boxer?
Let's start with the design. The BMW DC 04 retains the elegance and innovation typical of the brand, but with a futuristic touch. Its aerodynamic chassis and modern lines not only catch the eye but also offer improved aerodynamic efficiency. This improvement can translate into longer battery range, a crucial factor for those who use an electric motorcycle for daily travel.
Another distinctive feature of the BMW DC 04 is its power. Equipped with a cutting-edge electric motor, the DC 04 offers performance that can rival many internal combustion motorcycles. The immediate throttle response and smooth power delivery allow for a pleasant and effortless ride, making it an excellent choice for motorcycling enthusiasts.
But it's not just about performance. The BMW DC 04 was also designed with rider comfort in mind. With ergonomic seats and advanced suspension, every journey becomes a comfortable experience, even over long distances. Furthermore, the motorcycle is equipped with intelligent technologies that assist riding, such as traction control and several customizable riding modes.
Security has not been overlooked. The BMW DC 04 includes a number of advanced safety features, such as the regenerative braking system which not only helps save energy but also offers greater safety when braking. Furthermore, the high-visibility LED lights ensure that the rider is always clearly visible to other road users.
One aspect that many will appreciate is the eco-sustainability of the BMW DC 04. With zero direct emissions, this motorcycle represents a more environmentally friendly option than its internal combustion counterparts. BMW has also made great strides in ensuring that battery production and disposal are as sustainable as possible.
In conclusion, the BMW DC 04 is not just an electric motorcycle; it is a precursor of what the future of two-wheeled mobility could be. With an innovative design, exceptional performance and a strong focus on sustainability, the DC 04 could truly mark a turning point in the electric motorcycle market. If you are a motorcycle enthusiast or simply someone looking for a more eco-friendly way to travel, the BMW DC 04 is definitely worth your attention.
