In 2016, we unveiled SHIMANO STEPS E8000. As the first e-MTB dedicated e-bike system, it was celebrated globally by riders and was considered a true game changer.

We’ve since built on this experience, refined our design philosophy and raised the benchmark higher.

Read on to learn more about our new e-bike system and how we’re continuing to drive the e-MTB revolution to unmatched new levels.

1. More Power + Complete Control = Zero Excuses

Take on the steepest climbs and toughest trails in full confidence with 85Nm increased maximum torque. Tackle the ascent with eyes firmly focused on the top. Drop into the descent with certainty. Enjoy the ride. We know power is nothing without control. EP8 delivers smooth, direct power to ensure you’re always in complete control while experiencing a natural ride feeling.

2. Your e-MTB Ride, Your Way

Every ride is different. Every rider is unique.Your favorite trails change with the seasons. From dry, dusty days through to muddy, dirty rides. Sometimes you want to shred hard and fast. Occasionally it’s time to cruise.

Our E-TUBE PROJECT Cyclist App gives you the power to customize your ride way before you buckle up your helmet.

Choose from 10 levels of assist character, 5 levels of assist start or select and set the maximum amount of torque best suited to your ride style across 3 modes (Eco, Trail and/or Boost). Save your preferences as two different profiles and switch between them easily via your display if swapping the commute for weekend trails.

To get you out there riding, we’ve pre-loaded two profiles which are accessible via your display. These will have you covered for a variety of terrain, from challenging singletrack and flowing fire roads all the way through to technical rocky sections.

3. Smoother Pedaling

We believe all riders should feel in complete control in the saddle.

This belief, combined with our rider-first design approach, means we have raised the benchmark yet again to reduce drag by a further 36%. An improved clutch mechanism results in a more responsive ride, allowing for a smoother cut-off when pedaling above 25km/h.

EP8 delivers smooth pedaling and no surprises.

4. Lighter

When it comes to optimal performance off-road, you want a light, agile and nimble ride.

At 2.6kg, the EP8 weighs 300 grams less than predecessor drive units. It is truly one of the lightest drive units available and delivers best-in-class power for its weight.


5. Compact and Powerful


Don’t let size or looks deceive you. This sleek, slender and slim drive unit packs enough power to get you to the top of your next epic descent. A more compact, integrated drive unit also allows for increased ground clearance for when the trail turns technical.

6. Quieter

Despite its power, the EP8 operates with little noise so you can still enjoy the natural sounds of the trails without distraction.

7. Trail Mode Re-Booted

A newly refined Trail Mode utilizes all 85Nm of EP8’s power to boost rider comfort, control and confidence. Our most versatile assist mode to date is perfectly tuned for you to ‘set-it and forget-it’ so you can take advantage of almost any trail. The harder you push; you can be reassured the more power will be delivered to assist.

You receive the right power boost at the right time, safe in the knowledge you’ll always have maximum traction and control. Whether tackling loose sand or steep mountain ranges, the drive unit rapidly and seamlessly self-adjusts so you can concentrate fully on the trail ahead.

8. Looking After Your Ride

As sure as wheels turn, your bike will need fine-tuning from time to time. More miles and fun riding your EP8-equipped bike means wear out parts will need replacing. Whether riding local trails or hitting unexplored areas around Europe, you’re never too far from a Shimano service center or partner to help look after your bike.

9. Handle the Heat

Thanks to smart heat-conducting magnesium materials and a completely re-designed motor housing, EP8 can handle rising temperatures on climbs meaning you get maximum torque for longer. This is also helped further by a larger moulded-in surface area to improve heat exchange.

10. Greater Battery Capacity

We’re proud to say our batteries are renowned for keeping you out on the trails and riding further. We’ve expanded our battery line-up with 630Wh internal and external batteries for even more capacity and longer rides.

After 1000 full charge cycles, the batteries powering EP8 will still hold 60% max capacity, leaving you to maximize trail time all over again. They may even outlive the bike depending on how often and hard you ride.

This means you can keep lapping your favorite singletrack sections during the longest days and focus on the next switchback, not the battery indicator.
