Discover E-Gravel

We can all use a little help from time to time. An e-gravel bike is a great choice for riders who want a bit of assistance when riding steep, challenging roads, who are seeking more comfort, or who want to keep up with faster friends. In all of these cases, e-gravel bikes can significantly increase the fun factor! SHIMANO offers components that energize e-gravel cyclists.

EP8 drive unit

Our compact, lightweight (2.6kg / 5.7lbs) EP8 drive unit allows you to tackle steep climbs and tough gravel roads with full confidence thanks to 85Nm maximum torque. The EP8 drive unit delivers smooth, direct power to ensure you’re always in complete control while experiencing a natural ride feeling.

You can adjust the assist mode on the fly by either choosing between ECO, TRAIL and BOOST via the assist switch. ECO mode will give you maximum range while still providing more than sufficient support for the less severe terrain. Benefit from TRAIL mode which utilizes all 85Nm of EP8’s power to boost rider control, confidence and comfort. Our most versatile assist mode to date is perfectly tuned for you to ‘set-it and forget-it’, leaving you free to concentrate on tackling the toughest of terrain. Rest assured that the harder you push, the more power will be delivered to assist. You receive the right amount of assist at the right time, ensuring that you always have maximum traction and control. Whether tackling loose sand or steep mountain ranges, the drive unit rapidly and seamlessly adjusts assistance according to your input so you can fully focus on the road ahead. BOOST mode gives you full support with high but controllable power to climb the steepest tracks with ease.

Our E-TUBE PROJECT App connects you to your bike and gives you the power to customize your bike's assist profiles. You are able to perfectly adjust the settings to match your riding style, whether it’s for your next commute or your next gravel adventure. All assist modes are fully customizable. Go ahead and choose between high, medium or low for each mode setting to perfectly match the specific needs of your explorations.

Toggle support modes with drop handlebar shifters

E-gravel cyclists can switch support modes (Off, ECO, TRAIL and BOOST) by using existing GRX, Ultegra or Dura-Ace 11 speed Di2 levers on the bike. This means you’ll never have to take your hands off the handlebars to change assist mode on the fly. And having full control of your bike at all times is certainly key at high speeds or over bumpy terrain. Not only does this create an extra level of safety while easily toggling between support modes, it also eliminates the need for a separate controller on the handlebar. What you win is a cleaner look and better control of your ride.

Dedicated chainring

In addition, SHIMANO offers a 47-tooth SHIMANO chainring, which is larger than regular e-MTB and e-trekking chainrings, so you can put more power down on the pedals and reach higher speeds.

EP8 is optimized for off road riding and supports your performance on for your trip whether it’s a quick lap in the countryside or a long bikepacking trip. An e-gravel bike will ensure you’ll go faster, further and higher than you have ever been. It’s like a regular gravel bike but with more comfort and fun thanks to the assistance of SHIMANO STEPS. The versatile SHIMANO EP8 e-bike system can be found on a range of brands and models.
