favorite_borderWhy you'll love it
- Trek's Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy remove the battery without tools and lets you mount a water bottle cage – even on full suspension e-MTBs
- The dropper post upgrade makes Powerfly 7 even more capable
- It rides like a trail bike because it is one: Powerfly is built according to Trek's trail heritage with mountain bike tech developed over decades of innovation
- This bike expands boundaries: the Bosch system is equally suited to commuting, recreation and a ridiculously fun time on the trails
- This bike is built for the long-haul: it comes with a 500 Wh battery, the longest-range available from Bosch
Will my bike have a curved top tube?
Smaller frames (XS, S and M) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. The larger frame (L) has a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
Bosch Performance CX
Bosch’s Performance CX line is made for rugged off-road use with a maximum torque of up to 75 newton metres, sustained power into the high cadence range for sporty acceleration and a sleek mid-mount motor for ideal weight balance and obstacle clearance.
Bosch Purion Display
Bosch's Purion display features a fully-functional speedometer with a backlit display, service interval indicator and battery range indicator. Its thoughtful design allows riders to scroll through functions or choose the right level of support while maintaining contact with the handlebars.
This unique protection shield is lightweight yet robust, and protects the motor from rocks, logs and other trail debris.
The bike is already internally wired to accept additional lights. Go to your dealer and simply have them attached to the bike and plug them in.

Smart Wheel Size
The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.
Alpha Platinum Aluminium
Our premium lightweight aluminium is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strength and minimum weight.
Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 at the back lets you run wider tyres and a larger chain ring without affecting q-factor and pedalling efficiency.
