Shimano is presenting a new component group for e-bikes named STEPS (Shimano Total Electric Power System). The development is based on the idea that an e-bike has to stay a bicycle and needs to have a smooth and natural handling with a well-balanced support while pedalling.
Shimano’s first generation of e-bike components is based on four design principles:
1. Fun and Comfortable
E-bikes with STEPS technology have a similar riding feeling as a regular bicycle with a well-balanced support that continues until a maximum speed of 25 km/h. The 250W front motor drive system contributes to a good traction in various road conditions and can be used for recharging the battery when riding downhill, using the motor as an additional brake similar to engine-braking with a car.
STEPS can be combined with several shifting options. Most advanced is the SHIMANO SG-E500 8-speed internal geared hub that operates with electronic shift buttons. Options for V-brake and roller brake will be available. Furthermore, STEPS can also be combined with NEXUS internal geared V-brake and roller brake hubs and with existing rear derailleur systems.
2. Eco
Shimano introduces the E-Gain system that offers a multi-regenerative function to recharge the battery while riding. When riding in the E-Gain mode – for example when riding downhill as described above – energy is regained and stored in the battery. When operating the brake lever, the pedaling support stops immediately and starts supporting the brake power, regaining energy as well.
When using the battery charger, Shimano offers a battery charge of 1 hour to load a completely empty battery. Charging is possible with the battery on the bike but the battery can also easily be removed for charging. The 24V / 4.0Ah lithium ion battery can be recharged over 3.000 times. The battery is mounted at the rear carrier, with an integrated tail light. Also the front lamp is part of the concept, using a 6V / 2.4W super bright white LED lamp.
3. Smart and Clean
STEPS components have been exclusively designed for e-bikes. The functions to operate the system are fully integrated into the components, offering a clean and user-friendly design.
The electric switch buttons for riding mode, display mode and a light switch are integrated into the 4-finger brake levers, offering a clean cock-pit and smart cable routing. Cables have been provided with 5mm slim cable plugs to allow easy internal frame routing. The cycle computer offers a clear and quick overview of all e-bike functions such as riding mode and battery power but also a gear indicator, speed, trip and odometer. It features also a back light function and it can easily be removed from the bike for anti-theft.
4. Reliable
STEPS is developed to Shimano’s quality standards and is designed to comply with all major European standards. STEPS is a multi condition system, allowing a storage temperature of -20 until +60 degrees Celsius. Usage temperature is from -10 until +50 degrees Celsius. All components are fully waterproof. STEPS has been provided with a diagnostic system that allows dealers and bike manufacturers to download data directly from the components to the PC. Shimano’s dealer network also provides consumer support.
The official launch of STEPS will take place at the Eurobike show in Friedrichshafen, Germany, which will be open to consumers on September 4th.
Available on the market from: December 2010
