The system incorporates a 630 Wh Shimano battery inside the frame that provides up to 85 Nm of torque and a maximum power of 250 W with excellent autonomy.
PRECISION AND RELIABILITY
EP is a high-end component range for electric bikes from Shimano. The EP8 offers intuitive assistance on trails with the sensation of riding a regular MTB.
CENTER MOTOR
The traction-generating motor is positioned in the bottom bracket to effortlessly increase pedal power. Unlike hub motors, no force is generated when the bike speed exceeds 25 km/h.
EVEN MORE POWER
The torque of 85 Nm is among the highest on the market today. It is ideal for off-road use with very steep inclines and rough surfaces. The 85 Nm of torque generated by the central motor is directly related to the force applied to the pedals.
EXCESSIVE LOAD CAPACITY
High load capacity for long and confident rides without worrying about remaining charge. When you add 630 Wh to the power of your legs, you significantly broaden your pedaling horizons.
LONG-TERM PERFORMANCE
A larger battery capacity means a heavier total system weight. This trade-off increases both performance and longevity.
ANT+ CONNECTIVITY
The system uses ANT+ to communicate with third-party devices. This provides all sorts of additional information that can be displayed on the latest bike computers, like Garmin and Polar.
EFFICIENT IMPACT
A truly lightweight motor with a maximum power of 250 W enhances pedaling efficiency. The motor engages according to the power curve based on your use of the bike. The cadence triggers a smooth and efficient force without feeling resistance.
The motor located inside the bottom bracket requires more space to deliver its full power. As a result, the pedal crankarms are slightly wider apart, increasing the Q factor to 177 mm.
