The Powerfly 4 is our most affordable eMTB. It scores vital parts, such as the smoothly shifting Shimano drive and the powerful Bosch motor. It also comes with our easy-to-use Removable Integrated Battery (RIB) that is completely embedded in the frame and requires no tools to insert and remove. This bike broadens your horizons and lets you explore places you never thought you could reach on a mountain bike.

It's the right bike for you if…

… you are convinced of the e-bike revolution, and you want the performance and versatility of a mountain bike at a price that makes it easier for you to leave your car behind more often. You want more significant, more exciting off-road adventures, and you know that an eMTB is the best way to make them happen.

You get this equipment.

A robust, high-quality aluminium frame with an elegantly integrated, long-lasting 500 Wh battery, a Performance CX motor from Bosch with 250 watts of power and 85 Nm of torque for pedal assistance up to 25 km/h, a Bosch Purion controller, a 1×10 drive from Shimano and a suspension fork with lockout function. Thanks to Smart Wheel Sizing, every rider also benefits from the best fit: 29" wheels on larger frames 27.5" wheels on smaller frames.

Our last word

Our most affordable eMTB comes with the same powerful Bosch motor and intuitive controller as our most expensive eBikes, but with a smaller battery and more affordable parts.

 

Why you will love it

  1. Trek's Removable Integrated Battery System looks good and is user-friendly: It's fully integrated into the frame and therefore well protected, but can be easily removed without tools and even has space for a drinking bottle holder
  2. This bike expands horizons: The first-class Bosch system is equally suitable for the daily commute, for leisure-oriented rides and for a great time on the trail
  3. The Purion controller has a Walk Assist function and an intelligent eMTB mode that automatically supplies the required power depending on the terrain
  4. Thanks to the external charging connection, you can easily and conveniently charge the battery in the frame or when it is removed
  5. You can further optimise the versatility of your Powerfly by equipping it with a luggage rack and mudguards. In addition, thanks to pre-installed cables, you can easily mount lighting that is powered directly by the bike battery.

 

Features

Does my bike have a curved top tube?

Smaller frames (S) have a top tube that curves just before the seat tube. This design allows for a lower standover height, accommodating smaller riders who will find it easier to mount. The larger frames (M and ML) have a straight top tube because taller riders usually don't have a problem with standover height.

 

Bosch Performance Line CX engine

The Bosch Performance Line CX sets new standards with its performance of up to 85 Nm torque and an intelligent eMTB mode with Extended Boost, which automatically adjusts the support level to the terrain.

 

Removable Integrated Battery

RIB (Removable Integrated Battery) is a one-piece battery and cover combination with a built-in handle that can be easily removed from the frame and replaced without tools. Thanks to this feature, it is extremely convenient to remove the battery from the bike for transport, for securing or for easier charging.

 

What is the range?

The range assistant from Bosch shows you how far you can ride your eMTB on one charge. The data we preset for an average rider and for this bike model can be changed by you for a more accurate estimate of the range.

 

engine armour

Lightweight yet strong, this unique shield protects the motor from rocks, wood and other debris on the trail.

 

Luggage Rack Eyelets

Going on a big tour? Luggage rack eyelets make transport tasks a breeze.

 

Let there be light

The cables routed inside the frame enable uncomplicated retrofitting with additional lighting. Go to your retailer and get help choosing and installing your lights.

 

Smart Wheel Size

The optimal wheel size and "your" frame size are the perfect combination for agility and control on the trail.

 

Alpha Platinum Aluminium

Our lightweight, premium aluminium is continuously cold extruded and multi-butted, then hydroformed into complex tube profiles for maximum strength and minimal weight.

 

Rear side stand mount

Chainstay mounts allow for the installation of a jiffy stand that supports bikes of all sizes and stays out of the way when not in use. Gone are the days when you always had to lay your bike down or lean it against it.
