Overview

Introducing the 2021 BMW Definition CE 04, a striking prototype that redefines urban mobility and showcases the future of electric motorcycles. Aimed at the tech-savvy rider and urban commuter, this visionary concept marries advanced engineering with a bold aesthetic, presenting a unique alternative in the rapidly evolving e-mobility landscape. With its sleek lines and futuristic design, the CE 04 is not just a motorcycle; it’s a statement of intent from BMW, illustrating their commitment to sustainable transportation without sacrificing the excitement that comes with riding. At the heart of the Definition CE 04 is a cutting-edge permanent-magnet liquid-cooled synchronous motor, generating an impressive 42 horsepower at 4,900 RPM and delivering a robust torque of 61 Nm at the same rev range. This electric powertrain propels the CE 04 to a top speed of 120 km/h (74.6 mph), making it well-equipped for city riding and quick bursts on the highway. The 1-speed gearbox and belt final drive ensure a smooth, seamless acceleration, while the lightweight steel double-loop frame and meticulously designed suspension—featuring single-bridge telescopic forks and a single-sided swing arm—contribute to agile handling and stability, enhancing the overall riding experience. The Definition CE 04 is packed with innovative features that elevate its appeal. The motorcycle is powered by an 8.5 kWh lithium-ion battery, comprised of 40 individual cells, allowing for a range that meets the demands of urban commuting. With a charging time of just 3.5 hours to 80% using a standard charger—or a mere 65 minutes with a quick charger—riders can easily integrate the CE 04 into their daily routines. The bike's striking Mineral White Metallic finish complements its design, while advanced safety features like ABS-equipped brakes provide peace of mind on the road. The electric starter, combined with an ergonomic seat height of 855 mm, ensures that this motorcycle is accessible to a diverse range of riders. **

Pros

  • Innovative Electric Powertrain: The permanent-magnet motor provides impressive torque and acceleration, making it well-suited for urban environments.
  • Fast Charging Capability: The ability to charge to 80% in just 3.5 hours—or 65 minutes with a quick charger—adds convenience for daily use.
  • Agile Handling: A lightweight frame and advanced suspension geometry promote nimble handling and stability, enhancing rider confidence.

Cons

  • Prototype Status: As a concept model, the CE 04 may not be widely available in the market, limiting accessibility for potential buyers.
  • Weight Consideration: At 230 kg (507.1 pounds), it may feel heavier compared to traditional motorcycles, which could impact maneuverability for some riders.
  • Limited Range: While suitable for city commuting, the range may not meet the needs of those looking for longer-distance travel without frequent charging stops.
