The Powerfly 4 625 takes our most affordable electric mountain bike, and gives it a boost with a longer-range 625 watt-hour battery. Of course, you still get our user-friendly Removable Integrated Battery (RIB) system that's super easy to remove and reinstall, plus all the other parts that make Powerfly 4 your ideal entry into the joys of riding a pedal-assist bike on or off road.
You're sold on the e-bike revolution and want the capability and versatility of a mountain bike at a price that doesn't resemble the car you're trying to use less. You want bigger, better off-road adventures, and know that an e-MTB with the latest user-friendly tech is the best way to get them.
A tough yet refined aluminium frame that fully encases a long-range 625 Wh battery for sleek looks, a Bosch Performance CX (250 W, 85 Nm) motor that assists up to 25 km/h, a Bosch Purion controller, a 1x10 Shimano drivetrain and a suspension fork with lockout. Plus, Smart Wheel Sizing means riders of every size get a great fit ? 29? wheels on larger frames, 27.5? wheels on smaller frames.
This model gives you longer range battery than the standard Powerfly 4, so you?ll never be short on fun.
- 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
- This bike expands boundaries: the top-notch Bosch system is equally suited to commuting, recreation and a ridiculously fun time on the trails
- The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
- It's equipped with an external charging port for easy charging on or off the bike
- You can boost your Powerfly?s utility by adding a rack and mudguards, plus built-in wiring lets you easily install lights powered by the motor
Will my bike have a curved top tube?
Smaller frames (S) 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 frames (M and ML) have a straight top tube because taller riders with longer legs typically don?t have the same issues with standover height.
New Bosch Performance Line CX
The all-new Bosch Performance Line CX motor is lighter, smaller and quieter than previous versions, for cleaner integration and more nimble handling. It?s also more efficient so you can go further on a single battery charge. Use the intelligent eMTB mode to automatically adjust the amount of assist to match the terrain. It?s a set-and-forget mode that delivers just the right amount of power so you can focus on enjoying the ride.
Removable Integrated Battery
RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It?s the most convenient way to remove your battery for transport, security or just easier charging.
What is the range?
To see how far you can ride your electric mountain bike on a single charge, check out Bosch?s range calculator. We?ve auto-filled the variables for this bike model and the average rider, but you can make adjustments to get your most accurate estimate.
At Bikeology, we pride ourselves on our aftersales service and the quality of the products we sell. If we can’t stand over a product or a service, then we simply don’t sell it.
Every bike we sell comes with a lifetime warranty on the frame. A lifetime warranty on the frame entitles you to a new frame should there be any failure caused by fatigue or defective manufacture. Should this unlikely failure happen, we will process your warranty claim and rebuild your bike from the ground up completely free of charge*.
All other parts fall under the manufacturers warranty, but rest assured, we will do everything we can to get your bike back running smooth as silk as soon as possible, after all, you put your confidence in Bikeology. Should a problem arise, well, now it’s our time to prove you made the right decision in Bikeology.
As part of our drive to make your cycling experience the best it can be, we offer two years FREE servicing with every bike we sell.
What does this actually mean?
ALL labour charges are waived for 2 years from the date of purchase. For example, if your bike needed a service and a new tyre, the typical cost would be €40 plus €16 for a basic tyre. With our two years FREE servicing, this would only cost €16. If your gears need an adjustment, no charge at all!!! Buckled a wheel? Don’t worry, no charge at all!!! Annual service, No Charge……you get the idea!!! ZERO Labour charges for two years**.
*Any new parts needed will be assessed on a case by case basis.
** Fork, Shock and Dropper seatposts not included.
Trek began in 1976, when a pair of determined guys set out to make the best bicycles the world had ever seen. Their vision was grounded in unswerving principles: the product would be of the highest quality craftsmanship and it would bring the joy of cycling to a broader audience.
It was this philosophy that brought Bikeology and Trek together. We know that a quality bike will bring joy and passion to people from all walks of life. With our partnership with Trek, we will continue to bring the joy of the bicycle to more and more people. Some will simply use the bicycle as a tool in their daily life, for others, the bicycle will become a passion that will define the course of their life.
Bikeology and Trek have one thing in common, we are driven by adventure, guided by our history, inspired by community, enchanted by the freedom of the open road and committed, always, to creating, using and providing the world’s greatest bicycles.
