One new manufacturer of e-bike systems that has registered to attend Eurobike this year for the first time is the long-established brand AEG. The licensor for the brand is the Swedish appliance manufacturer Electrolux, which has partnered with Bike Solutions GmbH from Hofheim, Germany in order to develop, build and market its products.
One of the main new elements of the AEG e-bike program is the integration of the optically inconspicuous disc motor into an e-bike concept. The direct mount onto the bracket shaft allows the system to waive a special frame adapter or an extended wheelbase.
No gear box
The disc motor works without a gear box, which enables the unconditional use of a coaster brake. The performance of the silent and vibration free motor is 250 Watt nominal and can reach a maximum torque of 53Nm. By using the recuperation function the range can be extended. The production is located in Germany and patented worldwide. The torque read out occurs through a specifically developed sensor inner bearing, while a special AEG-eBike crank set to complete the disc motor set was also designed especially for the disc motor’s requirements.
Next to the disc motor, AEG will also present a motor which can be integrated into the rear wheel. By using a new, patented technology the motor reaches a performance of 250 Watt nominal and 50Nm maximum. The silent rear motor with integrated controller and torque measurement waives a gear box and enables an extended range through a recuperation function.
Magnetic plug
Two different 36V Li-Ion batteries offer the possibility to choose between a carrier and a downtube battery version. By offering these mount possibilities the battery system can be used for any type of bike, MTB/Cross, Trekking or City.
18650 brand cells, in different capacity variations, built the inner core of the batteries, mounted in Germany. A magnetic plug offers the option to charge directly on the bike or a removed battery. The integrated Mini-USB interface enables easy software downloads without having to disassemble or open any components. An electronic connector for the automatic shifting system “NuVinci Harmony” is already in place.
Racktime Snapit
The carrier battery is put on the carrier plate and therefore becomes a carrying element. To remain flexible, it is possible to mount a “Racktime Snapit” adapter for baskets and bags on the battery. The maximum capacity amounts to 17Ah (612Wh). Over a special mounting rail the downtube battery is mounted firmly and without play on the downtube. The end caps were beveled to enable the use of a ladies trapeze frame. The maximum capacity amounts to 11,6Ah (417Wh).
