AMBY stands for “Adaptive Mobility”. The BMW Motorrad Vision AMBY and the BMW i Vision AMBY interpret the fundamental idea of adaptive urban mobility on two wheels based on differing facets. Both vehicles are electrically powered with three speed levels for different types of road. The drive allows up to 25 km/h on cycle paths, up to 45 km/h on inner-city roads and up to a top speed of 60 km/h on multi-lane roads and out of town. A helmet, insurance licence plates and the relevant driving licence are required to be able to travel at higher speeds, however. While the BMW i Vision AMBY as a high-speed pedelec requires constant pedalling in order to gain assistance from the electric drive, the BMW Motorrad Vision AMBY is accelerated using the throttle grip and has footrests instead of pedals, as is typical of a motorcycle.
The modes available to the rider are stored in the app on the smartphone that connects to the respective AMBY vision vehicle.
Manual selection of the speed level is conceivable, as is detection of the road by means of geofencing technology, thereby allowing automatic adjustment of the top speed. As there is currently no legal basis for such a vehicle with a modular speed concept, the idea behind the AMBY vision vehicles is to prompt legislation that will enable this kind of set-up. In this way, the BMW Group is demonstrating that it will continue to be involved in providing mobility options in big cities in the future and offers innovative solutions.
The design: more than an e-bike.
The design of the BMW i Vision AMBY is defined by visual lightness and powerful athleticism. And every detail promises that it is capable of more than a regular e-bike. The frame structure is larger and the impression is one of greater strength and stability in every respect. The modern frame geometry feels like a mixture of racing bike and sporty e-bike. The upper frame tube, crafted from four sculptural aluminium profiles, represents an expressive and modern statement of intent – and not only in visual terms. A slightly rising sweep to its design underscores the dynamic intent. The space between the profiles also offers stowage room for a backpack or laptop bag. Located just before the handlebars is the smartphone integration pad, which holds the device safely in place using magnets and ensures it is highly visible.
The battery is positioned in the centre of the frame. Its 2,000 Wh enables a range of up to 300 km (186 miles), depending on the riding mode. Thanks to fast charging technology, it recharges in only three hours. The drive unit, which is positioned close to the pedals and is also black in colour, only provides assistance when the pedals are being turned. Power transfer is by low-maintenance toothed belt, and the transmission is integrated into the drive system. A sophisticated single-sided swinging arm otherwise unique to BMW Motorrad links the rear wheel with the frame. 120 mm of suspension travel front and rear is ideal for all applications in and around town at speeds of up to 60 km/h (37 mph). The 27.5-inch wheels are fitted with larger and wider tyres than normal in order to ensure exceptional comfort and safety even at higher speeds.
Colour and material concept featuring depth and unexpected details.
As compared to a conventional combustion engine, the concept of the electric drive in the BMW Motorrad Vision AMBY means there is little in the way of visible mechanics.
For this reason, its technical heart is deliberately disguised and showcased in a striking machine-like style. This accentuates the highly elaborated colour and material concept, which goes well beyond the traditional dark underlying colour scheme and use of white highlights.
In its use of materials, the BMW Motorrad Vision AMBY cross-references two other concept vehicles that will also see their world premiere at the IAA Mobility 2021: The BMW i Vision Circular and the BMW i Vision AMBY. The trim material used on the energy storage unit – known as “floating grey polymers” – is also used in the bumper of the BMW i Vision Circular. It consists of recycled plastic and can itself be fed back into the material cycle at the end of the product lifecycle. Meanwhile the material used for the seat is also to be found in the saddle of the BMW i Vision AMBY and in the tyres of the BMW i Vision Circular. Based on recycled plastic granulate and sporting a fascinating terrazzo look, it demonstrates how several materials can be given a second life with a new form and function.
