BMW's Electric Motorcycles: Leaks and Patents
BMW has introduced several electric motorcycles since 2015. Functional testing studies, concepts and vehicles. Bayerische Motoren Werke even patented the brand-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 launching the CE models, which are dedicated to electric scooters and urban mobility concepts like the BMW CE 02, the company is now focusing its efforts on larger electric motorcycles designated by the "DC" acronym. The new names include DC 01, DC 02, DC 03, DC 04, DC 05, DC 06, DC 07, DC 08, and DC 09, for motorcycles, parts, and accessories. In June 2019, BMW unveiled the Vision DC Roadster concept, which introduced its electric motorcycle lineup, with "DC" standing for "direct current." Currently, there are no aftermarket accessories available for these new BMW electric motorcycles.
Modular monocoque frame with integrated battery
At the end of December 2023, BMW published a new international patent application for a modular monocoque frame for electric motorcycles. This frame includes a central battery housing made of carbon fiber-reinforced composite plastic, such as Kevlar. Hybrid constructions using lightweight metals such as aluminum or titanium are also possible, especially in critical areas such as the steering head and swingarm mount. The modular design offers the flexibility to tailor the wheel suspension to the specific model, reducing costs and simplifying production thanks to a smaller number of components.
Could the DC 04 be BMW's first electric motorcycle?
In March 2023, patent drawings emerged 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 will likely use components from the CE 04 electric scooter, which has been available since 2022, but with a reorganization of the battery pack and motor to accommodate motorcycle use. The electric motor would transfer power to the rear wheel via a bevel gear system and a toothed belt, with a 90-degree deflection.
BMW Vision DC Roadster and the electric boxer engine
The Vision DC Roadster concept, presented in 2019, attracted attention for its design inspired by the classic two-cylinder boxer engine, with a cooling system located in the so-called "cylinders." A patent application filed in June 2022 suggests that BMW is exploring this direction, envisioning cooling cylinders mounted directly on the drivetrain, 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 for definitive conclusions.
100 kW BMW E-Power Roadster Concept
In December 2019, BMW presented the E-Power Roadster Concept, an electric motorcycle with a less visionary design than the Vision DC Roadster, but with a power output of 100 kW (136 hp) and a total weight of approximately 300 kg. Despite this, BMW has not yet completed 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, potentially ranging 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 seems to indicate a long-term planning strategy by BMW, thus protecting names and technologies from potential claims by other manufacturers. In the future, we're likely to see models such as e-roadsters, e-tourers, and e-aDVENTURE bikes. In the meantime, the image gallery offers a glimpse into 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 hp), accessible with a class A1 driving licence from the age of 16 or with the B196 extension to the car driving licence. Both models are intended for urban mobility, ideal for short trips in metropolitan areas.
BMW Electric Models Production at TVS in India
BMW is collaborating with its Indian partner TVS on the development of future electric models. TVS already produces the G 310 models for BMW, and in 2023 it began production of the BMW CE 02, the first electric model in the range.
The BMW DC 04 promises to be a significant breakthrough 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 brand's signature elegance and innovation, but with a futuristic twist. Its aerodynamic frame and modern lines not only catch the eye but also offer improved aerodynamic efficiency. This improvement can translate into greater battery range, a crucial factor for those who use an electric motorcycle for daily travel.
Another distinguishing feature of the BMW DC 04 is its power. Equipped with a state-of-the-art electric motor, the DC 04 offers performance that rivals many internal combustion engine motorcycles. The immediate throttle response and smooth power delivery allow for a pleasant and effortless ride, making it an excellent choice for motorcycle 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 ride becomes a comfortable experience, even over long distances. Furthermore, the bike is equipped with intelligent technologies that assist the rider, such as traction control and several customizable riding modes.
Safety has not been overlooked. The BMW DC 04 includes a series of advanced safety features, such as the regenerative braking system, which not only helps save energy but also offers greater safety when braking. Furthermore, high-visibility LED lights ensure 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 engine 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 isn't just an electric motorcycle; it's a precursor to what the future of two-wheeled mobility could be. With its 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're a motorcycle enthusiast or simply looking for a more eco-friendly way to travel, the BMW DC 04 is definitely worth your attention.
