The Japanese component giant, Shimano, announced on it’s website, the introduction of a new groupset for e-bikes called- STEPS.
SHIMANO enters e-bike market with STePS
STEPS is developed with the idea of system component design. Which means that every individual component works better when the other STEPS components are also integrated in the groupset. STEPS is a pedelec system which engages when a rider is pedaling and cuts out once 25km/h is reached. The STEPS drive unit has a compact design and with weight of 3.1 kg, it is one of the lightest drive units in the market. The compact and lightweight design improves rider control in all conditions and is easier to handle by a wider range of riders. Talking about range, STEPS has three types of power support modes; eco, normal and high. The preferred mode can be selected by an easy to operate switch. The eco mode has a range up to 120km. Normal mode 100km and the high mode 80km*. The STEPS cycling computer gives feedback about the selected mode, battery life, riding speed, distance, etc.
The STEPS battery has a capacity of 418Wh and it takes four hours to completely charge the battery. There are two position types of batteries. A rear carrier type and a down tube type. The battery life is 1.000 cycles. After 1.000 cycles the battery still charges more than 250Wh.
STEPS has the possibility to integrate with SHIMANO’s Di2 internal hub gears. This integration gives STEPS a number of valuable advantages. First the SHIMANO Di2 internal hub gears maintain shifting performance under high chain tension by reducing motor power while shifting. Besides the shifting performance also the total integration is an important feature. All individual components are designed to work as a flawless system. Another advantage is the possibility to connect STEPS to a PC via SHIMANO’s E-tube* project. E-tube gives quick and easy access to the STEPS system for simple installation and set-up options. For instance changing the function of the buttons on the switch, firmware updates and diagnostic analyses.
Special for the STEPS system, SHIMANO made a reinforced chain dedicated for E-bike usage. It is treated with SIL-TEC* coating and for front single gear only.
SHIMANO’s STEPS components are designed to be ridden all year round. STEPS can be used from 10 degrees Celsius below zero to 50 degrees Celsius. For advice and service SHIMANO has a strong and proven European wide service network.
The initial delivery to OEM’s is planned in August 2014.
* These ranges are set by multiple tests at 23 km/h on flat roads. The actual range can be different depending on the speed, roads, weather conditions (wind), etc.
* SIL-TEC is SHIMANO’s low friction chain surface treatment. Superior to simple coating, SIL-TEC is an advanced plating process that improves system performance through the use of imbedded fluorine particles. SIL-TEC treated products run smoother and wear longer in all conditions.
* E-tube transmits interactive signals and power supply to Di2 components by a ‘plug and play’ connection. SHIMANO’s SM-PCE1 device connects a PC to the Di2 components for the set-up of the Di2 components, diagnostic analyses and firmware updates.
