  • BMW CE 04 Electric Scooter unveiled: Connectivity meets mobility

    BMW Motorrad has unveiled the new BMW CE 04 electric scooter. With its electric drive, forward-looking design and innovative connectivity solutions, the new scooter merges transport and communication functions into a new brand of personal urban mobility.



    “The new BMW CE 04 is logical and at the same time rethought continuation of BMW Motorrad’s electromobility strategy. Urban areas are its element. This is where it sets a new benchmark – in terms of both technology and visual style.” Florian Römhild, Project Manager BMW CE 04.

    With a maximum output of 42 hp, the new BMW CE 04 has a powerful motor for an exciting riding experience. A maximum speed of 120 km/h means the CE 04 is ready not only for the city but for highways as well.



    The new BMW CE 04 has a battery cell capacity of 60.6 Ah (8.9 kWh), providing an estimated range of 80 miles. This enables day-to-day emission-free commuter riding and for smaller-scale fun tours on the weekend – with complete peace of mind.

    “The new vehicle architecture with a flat storage battery in the underbody is what enables the numerous smart solutions that make the CE 04 so distinctive.” Clemens Pinnekamp, Project Manager Development BMW CE 04

    Powertrain and Battery

    Maximum output is 42 hp @ 4,900 rpm and 60 Nm of torque @ 1,500 rpm. The new BMW CE 04 offers effortless riding in urban environments, as well as on longer trips – even when carrying two people.

    BMW Motorrad has drawn on cross-over technology with BMW automobiles as part of the development process. For example, the new BMW CE 04 uses a lithium-ion battery module manufactured exclusively with green power, as in the current BMW iX and i4. Other components for controlling the high-voltage battery system also derive from the passenger car sector.

    Engineers paid particular attention to the quality and durability of the batteries so as to ensure the rider is able to make full use of the range even after many years of service life.



    One of the main technological challenges here was to achieve optimum cooling of the high-voltage battery. On the one hand, it was necessary to avoid excessively low temperatures due to the fact this results in an enormous increase in the cells’ internal resistance, thereby reducing power.

    On the other hand, high temperatures have to be prevented since this would impact negatively on cell lifetime. In the BMW CE 04, this is taken care of by an air-cooling system. Here, heat is dissipated from the high-voltage battery via a cooling plate with longitudinally arranged cooling fins on the underside of the vehicle.

    Drive power in the new BMW CE 04 is provided by a permanent magnet EMP 156 electric motor mounted in the frame between the battery and the rear wheel. The electric motor is liquid-cooled, and the radiator is installed at the front of the vehicle.

    Torque is transmitted via a single-stage primary gearbox and from there via the secondary drive with a maintenance-free toothed belt to the rear wheel. The total gear ratio is 10.5.

    A notable comfort feature of the new BMW CE 04 is the reversing aid. It is activated from a left-hand handlebar-mounted switch, and the rider’s attention is drawn to it by the relevant indication in the TFT display. When the activation switch is pressed down, the BMW CE 04 can reverse at a walking pace, making it easier to manoeuvre.

    Charging and Recuperation

    The BMW CE 04 is ridden in exactly the same way as a scooter with an internal combustion engine. The vehicle recuperates energy automatically whenever possible. As such, the energy recovery system extends the range and increases efficiency.

    For example, recuperation starts when the throttle is closed, kinetic energy is converted into electrical energy and – as in a combustion engine – the generator function of the electric motor creates a drag torque which depends on the degree of recuperation. The drag torque generated by the electric motor is like the familiar "engine braking" that takes effect when rolling off of the throttle in a vehicle powered by a combustion engine.



    The 147.6-volt lithium-ion battery is charged via the integrated charging device, either via a Level 1 household socket, a Level 2 Wallbox or a Level 2 public charging station. The charging socket is based on automobile standards and is located underneath a cover in the front right-hand leg area. A storage compartment on the right-hand side of the vehicle houses the standard Level 1 charging cable.

    If the BMW CE 04 is equipped with the optional Level 2 quick charging cable, charging times are significantly reduced. A DC-DC converter converts high voltage to low voltage so as to feed the 12-volt vehicle power system, the 12-volt battery (12 V/5 Ah) and the control units.

    Charging times for 0 to 100 per cent battery capacity, take 4 hours and 20 minutes with the supplied Level 1 (2.3 kW) charging cable. With the optional Level 2 charging cable (6.9 kW) charging time is reduced to just 1 hour and 40 minutes. From 20 to 80 per cent, the charging time is just 45 minutes with the Level 2 charging cable.

    Equipment and Electronics

    The front twin-disc brake ensures secure deceleration, supported by a rear single-disc system. Standard BMW Motorrad ABS ensures a high level of active safety. The front 265 mm twin-disc brakes and 4-piston fixed callipers ensure powerful, safe deceleration. At the rear, there is a single 265 mm disc and single-piston floating calliper. In order to achieve stable pressure and optimum controllability, all brake lines are steel-wrapped. The standard parking brake is activated automatically when the side stand is folded out.

    BMW Motorrad ABS ensures a high level of active safety. The Bosch 9.3 2-channel ABS allows for independent regulation of the front and rear brake circuits. The optional ABS Pro provides even greater safety when braking. By means of a banking sensor, ABS Pro also controls braking when leaning in corners, thereby offering the greatest possible safety.



    This traction control system in the new BMW CE 04 is comparable to the Automatic Stability Control in BMW motorcycles with a combustion engine. ASC limits engine torque in relation to rear-wheel slip. In order to enable optimum controllability of the drive torque, the power electronics of the electric motor monitors the motor speed of the rear wheel and reduces drive torque when the grip level is exceeded.

    In this way, ASC supports the rider when accelerating from a stop, preventing uncontrolled spinning of the rear wheel on road surfaces with a reduced friction coefficient such as wet cobblestones. In addition, ASC serves to prevent locking of the rear wheel during times of intense recuperation and the resulting drag torque, especially on roads with a low friction coefficient.

    Optional Dynamic Traction Control (DTC), available as part of the Premium Package, provides even greater riding safety resulting from excellent traction. DTC enables safer acceleration, especially in a leaning position.

    Geometry and Handling

    The goal of BMW Motorrad in developing the suspension of the new BMW CE 04 was to combine excellent handling qualities and a high level of comfort with directional stability at high speeds and the robustness required for day-to-day commuter use.

    With a wheelbase of 66-inches, a steering head angle of 26.5 degrees and a castor of 4.7-inches, the new BMW CE 04 has basic geometrical suspension data that is similar to that of a motorcycle. On the road, easy manoeuvrability – especially in urban traffic – and a high level of ride stability when travelling swiftly along country roads or at even faster speeds on the motorway is experienced by the rider. In urban traffic, in particular, the riding experience is characterized by extremely light handling and excellent slow-speed properties.



    Wheel control, in addition to suspension and damping, is taken care of at the front by a single-bridge telescopic 35 mm fork. The rear wheel suspension consists of a single-sided swingarm. At the rear, suspension and damping are performed by a spring strut placed on the left-hand side, directly controlled and adjustable at the spring mount. The spring travel is 4.3-inches at the front and 3.6-inches at the rear, thereby offering a high degree of comfort.

    At the front, the new BMW CE 04 rolls on a 3.5 x 15-inch light-alloy cast wheel while at the rear is a 4.5 x 15-inch light-alloy disc wheel. The new BMW CE 04 is fitted with a 120/70 R15 67H tire at the front and a 160/60 R15 56H tire at the rear.

    “The new BMW CE 04 is the link between the user’s analogue and digital worlds. It is both a means of transport and a means of communication for the big city commuter. With its forward-looking design thanks based on an innovative package, it sets out to redefine the scooter segment.” Edgar Heinrich, Head of Design BMW Motorrad.

    Design and Features

    The new BMW CE 04 embodies a forward-looking design philosophy for urban two-wheeled mobility featuring an innovative style that showcases the electric drivetrain technology while instantly identifying the scooter as a member of the BMW Motorrad family. It is an avant-garde urban design statement. Not following traditional styling, the BMW CE 04 offers a synthesis between the lightness of a scooter and the technology of a motorcycle.

    The flat battery in the underbody provides new freedom of design, such as the side-hinged and illuminated storage compartment with an emergency release, giving the rider easy access to the helmet as well as the charging cable. Like the storage compartment at the front of the leg area, this storage space can be reached from a sitting position if necessary – a first among scooters.



    A slim rear end – making for an iconic design that is unique among scooters – is possible thanks to the swing-arm-mounted number plate holder with lighting. In addition, the side stand is integrated into the styling.

    The avant-garde design stands in contrast to technology that is partially visible yet well integrated into the design. In the rear section of the BMW CE 04, for example, the motor, single-sided swingarm, suspension strut and toothed belt are deliberately designed to be open and visible.

    The standard modern surface finish is in a striking Light White, complemented by matt black sections in the front and side areas as well as the “floating” seat. This underscores the visual lightness of the BMW CE 04.

    The wheels - in a black matt finish with a disc-wheel look - blend harmoniously with the overall image. The new BMW CE 04 in optional Avantgarde Style is a striking, future-oriented colourful statement of contemporary urban mobility. In this style, Magellan Grey metallic – a warm, refined grey tone – is supplemented with a black/orange seat, an orange wind deflector and several graphics.

    Console and Display

    The new BMW CE 04 comes equipped with a standard 10.25-inch TFT colour display screen with integrated map navigation and smartphone connectivity. Its excellent readability and clear menu navigation put the new BMW CE 04 at the top of the scooter segment. For the first time, the new 10.25-inch colour display makes it possible to display a navigation map in the instrument cluster, so no additional navigation display is needed.

    For day-to-day use, the screen is fitted with a hardened and extremely tough glass cover. It is anti-reflective for the optimum display and protected from soiling and scratches by means of an anti-fingerprint coating. The full HD resolution screen with 1920 x 720 pixels offers excellent detail and sharpness.

    The display can be used in full-screen mode or, alternatively, in a split-screen view which allows several functions to be shown simultaneously. The main display – the “Pure Ride Screen” – shows the speedometer along with the basic functions and selection menu. The navigation map is displayed if navigation is active via the BMW Motorrad Connected app. The additional split screen shows either the on-board computer, the on-board trip computer, arrow navigation, a current phone call or media.



    The screen offers a wealth of additional information, including the display of the battery charge state (SOC = State of Charge) and the energy balance. It shows whether energy is currently being converted into propulsion or recuperated. This information helps the rider in their efforts to ride as efficiently as possible.

    Vehicle functions such as “Settings”, “Navigation” and “Communication” are operated using the standard handlebar Multicontroller. The tiles shown can be used to select the “My Motorcycle”, “Navigation”, “Media”, “Phone” and “Settings” menus. There is a seamless integration of the display and operation of the optional extras such as the Dynamic riding mode (part of the optional Ride Modes Pro) and standard functions.

    Its 10.25-inch TFT colour screen provides the perfect platform for using a fully interactive map view in conjunction with the navigation system of the BMW Motorrad Connected App. The navigation map is “mirrored” onto the screen via wireless LAN. As such, the new BMW CE 04 offers an unprecedented dimension of map navigation. The 10.25-inch TFT colour screen allows a particularly wide range of integrated navigation options to be operated via the Multicontroller. Thanks to the smartphone-based architecture, navigation is always on board: it couldn’t be simpler to make route changes during a coffee break or share a route with friends.

    The smartphone app provides the rider of the new BMW CE 04 with the latest navigation software and maps on an ongoing basis, as well as offering the latest functions. The app allows maximum planning flexibility: it can be used for route planning itself, importing planned routes from Basecamp or downloading route suggestions from websites.

    The BMW Motorrad Connected App can be downloaded free of charge from the Google and Apple app stores. It also provides additional functions such as route saving and the display of other travel statistics and information. In this way, saved routes can also be shared directly with other motorcyclists via the Rever community.

    A smartphone can be securely accommodated in a storage compartment on the left-hand inner side that is protected from the elements and ventilated by an electric fan, and its battery can be kept ready for use via a USB connection.



    The hinged storage compartment lid is automatically locked with the central locking system. Inside the storage compartment, there is a holding device in which a smartphone can be securely fastened during travel by means of a flexibly sized fixture. Up to 1.5A charging current (charging capacity up to 12W) is available at the USB-C socket located in the storage compartment, which also enables quick charging depending on the smartphone type. A ventilation system reduces the heat generated when the smartphone is in use, while a seal on the storage compartment lid protects it from outside elements.

    Lighting

    The state-of-the-art LED lighting technology on the new BMW CE 04 includes the high/low beam headlamp, the rear light, brake light and turn signals. Even greater safety at night is offered by the optional turning light - Adaptive Headlight.

    The adaptive turning light works by switching on additional LED elements in the main headlight that are fitted with their own reflectors, depending on the banking angle. The turning light switches on automatically from a banking angle of more than 10° and at speeds of over 6 mph. The additional lighting effect can be experienced up to a banking angle of 25°.

    In the new BMW CE 04, a U-shaped LED light guide, which also functions as the LED daytime running light provides the characteristic image of a BMW Motorrad vehicle, ensuring a high level of recognizability.

    The lighting functions on the BMW CE 04 deliver more than just the required excellent down-the-road illumination. There are practical benefits, too: when the ignition is switched on, a “Welcome” light is activated. The main headlamp and rear light go on, remain on for a short time and then fade into standby mode before the motor is started.

    Here, transitional fading involves a dimming process in stages. After being switched off, the front and rear lights are switched on to “Goodbye” for a brief moment before finally darkening slowly.

    Another new function is the “Follow me home”. After being switched off, the riding light can be activated by briefly pressing the high beam button. Other non-guidance functions and light sources remain switched off. This function ensures optimum visibility at night, for example when manoeuvring in parking spaces or opening the garage at home.

    Riding Modes

    In developing the BMW CE 04, BMW Motorrad focused on providing the rider with the choice between maximum efficiency and maximum riding fun. Accordingly, the new BMW CE 04 features three riding modes “ECO”, “Rain” and “Road” as standard. An additional “Dynamic” riding mode is available as part of the optional Premium Package, enabling the scooter to accelerate even quicker.

    ECO mode: In this mode, drag torque during coasting is significantly increased, while maximum recuperation combined with a limitation on acceleration and therefore energy consumption allows for an extension of the range. The rider feels the increased drag torque as a slight intensification of deceleration torque when releasing the accelerator. This riding mode supports an energy-efficient riding style when there are a few more miles to cover than expected.

    Rain mode: In this riding mode, there is a reduction in drag torque while coasting and during acceleration. In practice, the rider benefits from a smoother and therefore very safe response of the electric drive, especially in adverse road conditions – for example when it is raining.

    Road mode: Here, full acceleration is available. The standard range is available in this mode.

    Dynamic mode: In this optional mode, full acceleration is combined with intense recuperation via a direct set-up of the performance characteristic curve, creating a powerful “motor brake” for highly dynamic riding. In this riding mode, the new BMW CE 04 shows its sporty, dynamic side and exudes all the fascination of forward-looking electric mobility.

    The 2022 BMW CE 04 is available in the following colours:
    • Light White (standard)
    • Magellan Grey Metallic Avantgarde Package ($225)



    A Premium Package ($1,650) will be available and will include:
    • Adaptive headlight
    • Ride Modes Pro
