E-mountain bikes level the playing field between riders with different fitness levels and abilities. Uphills become a joy, taking riders to places they couldn’t previously reach, and prolonging the riding enjoyment. And when riding uphill can be quicker, it gives riders more time to enjoy the downhills.

This is achieved by a lightweight and compact E8000 drive unit, designed around the concept of being intuitive and providing a natural feeling for the rider. The drive unit is compact so frame manufacturers can make e-MTB frames with shorter chainstays, giving riders have better maneuverability on the trail. The cranks sit with a narrow Q-factor, so riders feel like they are riding a standard mountain bike. And most importantly the lightweight unit is controlled intuitively by a lefthand power mode switch with three settings (Eco, Trail and Boost) for different types of terrain. 


Shimano first launched its urban and leisure-orientated e-bike components (E6000) in 2014. Now, with the knowledge and experience that comes from many years of developing high-end MTB components, Shimano unites its technological expertise with the release of its E8000 components, dedicated towards the rigors and demands of e-mountain biking but designed so that riders can experience the true sensation of the mountain bike.

  • The SHIMANO STEPS E8000 MTB groupset features a powerful drive unit (DU-E8000). 
  • Power for the motor is provided through a large capacity 500Wh battery (BT-E8010), complete with battery mount (BM-E8010). 
  • Driving force is transmitted through a dedicated chainring including crank arms (FC-E8050/E8000) and a 34T or 38T chain ring (SM-CRE80-B/CRE80), which comes with an optional chain retention device (SM-CDE80).
  • The system is controlled through a sleek bar-mounted cycle computer (SC-E8000) and a FIREBOLT switch unit for assistance control (SW-E8000-L), along with a speed sensor set (SM-DUE10) for the rear wheel. 
  • The remaining components of the drivetrain can be supplied from Shimano’s Di2 MTB components (XTR/XT) or mechanical 10 and 11 speed drivetrains.
  • The new SHIMANO STEPS MTB system can communicate via Bluetooth with the E-TUBE software platform allowing you to change settings and customize your set-up via computers, tablets or smartphones.

The compact and powerful 70Nm of torque provided from the SHIMANO STEPS MTB motor is designed to make every moment of every ride fun.

The drive unit is held in a triangle formation around the bottom bracket resulting in secure, direct and efficient power transfer from the rider to the cranks. Its compact design incorporates cooling fins on the drive side for the heat dissipation from the motor.

Creating a natural feeling ride from the SHIMANO STEPS MTB motorized drive unit was an important consideration. Riders pedal much like a traditional bike, yet they can choose to receive different levels of assistance when they step on the pedals. Riders can also change gear too, much like a normal mountain bike, with 10 or 11-speed drivetrain and mechanical or Di2 shifting options available. 

The compact drive unit accommodates frames with shorter chain stays to give E8000-equipped bikes typical mountain bike handling and maneuverability. It also provides a Q-factor (ie the distance between the outer edges of the crankset) in line with DEORE XT cranks, helping to retain a natural feeling. 

Power for the motor is delivered by a slim but durable, low profile and waterproof 500Wh battery on the downtube. A secure mount keeps the battery firmly in place even over rough terrain, yet removing the battery for charging is simple with a sideways release mechanism.

Connected to the motor is either the hollow crankarm (FC-E8050) or the solid crankarm (FC-E8000), both of which are available with 34T or 38T chain rings (SM-CRE80-B/CRE80) for 10 or 11-speed cassettes. Chainrings feature Shimano’s Dynamic Chain Engagement technology and, together with an optional chain retention device (SM-CDE80), ensures chains remain on drivetrains.

The system is controlled by the compact SHIMANO STEPS MTB colour LCD computer (SC-E8000) to offer riders their gear number, power assist mode and battery range information.

The power assist modes are controlled by a dedicated MTB handlebar switch (SW-E8000-L), allowing the rider to change between Eco, Trail and High Power modes, plus the Power Walk mode.

SHIMANO STEPS MTB components will be available from October 2016. Set your sights on exploring new grounds this Autumn.
