Fully Suspended Electric Mountain Bike – Size L (178–185 cm)
The Wilier 903 Trn Pro Xt 1X12 electric bike is the fully suspended electric mountain bike with all-mountain geometry for thrill-seekers. With the Shimano EP8 pedal assist system, you will experience adrenaline drops and great efficiency in your climbs. The system integrates a Shimano 630 Wh battery inside the frame that provides torque of up to 85 Nm and a maximum power of 250 W with excellent autonomy.
PRECISION AND RELIABILITY
EP is a high-end component range for Shimano electric bikes. The EP8 offers intuitive support on trails, giving the feel of riding a regular mountain bike.
CENTRAL MOTOR
The traction-generating motor is positioned in the bottom bracket to increase pedal power in a simpler and more powerful way. Unlike hub motor solutions, no force is generated when the bike speed exceeds 25 km/h.
EVEN MORE POWER
The 85 Nm torque is one of the highest on the market today. It is ideal for all-terrain use on very steep inclines and rough surfaces. The 85 Nm torque generated by the central motor is directly related to the force applied to the pedals.
EXCESSIVE LOAD CAPACITY
Significant load capacity for long and confident rides without worrying about residual charge. By adding 630 Wh to the power of your legs, you greatly expand your riding horizons.
LONG-TERM PERFORMANCE
A larger battery capacity means a higher 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 kinds of additional information that can be displayed on the latest bike computers, such as Garmin and Polar.
EFFECTIVE IMPRESSION
A truly lightweight motor with a maximum power of 250 W increases pedaling efficiency. The motor engages based on the power curve according to how you use the bike. The cadence triggers a smooth and efficient force without feeling any resistance.
MAKE WAY FOR POWER
The motor located inside the bottom bracket requires more space to deliver its full power. As a result, the pedal cranks are slightly more spaced apart, increasing the Q factor to 177 mm.
