SHIMANO STEPS characteristics
Assist profile
On assist bicycles with cycle computers, you can select from two assist profiles, [BASIC] and [Fine tune], that
determine the riding comfort. In addition, by connecting to E-TUBE PROJECT, you can perform a wider range of
customization than before.
[BASIC]
Select the level of assistance from three modes according to riding conditions. One of the following two
combinations is set by default:
Assist mode Level of assistance Main application
[BOOST] / [HIGH] Increase Precipitous mountain roads and steep slopes
[TRAIL] / [NORMAL] * 1 Intermediate Gentle ascending slopes and level ground
[ECO] Decrease Long distance riding on level ground, level parks with
signals
* 1 Depending on the cycle computer, [NORM] is displayed.
Pursuing the bicycle-like feel
With its lightweight and compact design, the drive unit is meant to provide a bicycle-like feel with reduced
operation noise and powerful output.
Improved customization
Automatic gear shifting is compatible with both the assist profile and the rear derailleur, enabling a wide
range of customization.
Compatibility with a wide range of bicycle categories
From sport riding and city cycling to cargo bicycles designed for transporting goods, assist bicycles can be used
for many applications.
[BOOST] / [TRAIL] / [ECO]: A combination of assist modes for sport riding.
[HIGH] / [NORMAL] / [ECO]: A combination of assist modes for comfortable riding in urban settings.
SHIMANO STEPS characteristics

[Fine tune]
The riding comfort of the assist bicycle is determined by the relationship between the force applied to the pedals
and the drive unit output, and the maximum output of the drive unit. [Fine tune] supports a wide range of
riding conditions with up to 15 levels of settings.

Automatic gear shifting
This product provides automatic gear shifting not only with conventional internal geared hubs, but also for
bicycles with rear derailleurs.
In addition, you can expand the automatic gear shifting settings to configure the following detailed settings in
E-TUBE PROJECT. You can register up to two combinations of these settings, and use the shift switch to change
When the battery level is low, the level of assistance is automatically reduced to increase the maximum
traveling distance.
When battery levels are unstable, or when assist power is not required, you can turn assist mode to
[OFF].
The number of settings registered by default depends on the bicycle.
The settings and gear position can be customized in E-TUBE PROJECT.
The drive unit's maximum output may be capped by the bicycle manufacturer depending on national
and regional laws and regulations.
