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 Line CX (250 W, 85 Nm) motor that assists up to 20 mph (25 km/h in Europe), a Bosch Intuvia smart system 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 Intuvia controller has Walk Assist and an intelligent e-MTB 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
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.
Bosch Performance Line CX motor
The Bosch Performance Line CX sets the standard for eMTB performance with up to 85 Nm of torque and an intelligent eMTB mode with Extended Boost that automatically adjusts the amount of assist based on the terrain.
Bosch LED Remote
The Bosch smart system LED remote lets you easily change assist modes, activate walk mode or turn on optional lights. The bright LEDs are easy to see in any light, and show you your battery level and assist mode at a glance.
Bosch Intuvia 100 display
The Bosch smart system Intuvia 100 display puts your ride data front and centre with a large-font high-contrast display that's easy to read in any weather. You get eBike Lock theft protection, and best of all, it's completely wireless and connects to the remote via Bluetooth.
Bosch eBike Flow app
The new eBike Flow app turns your ride into a personalised experience. Use it to customise your motor's assist behaviour, track your ride stats and integrate your data with apps like Strava and Apple Health. There's even handy features like navigation and service reminders.
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.

Summit Cycles work will all major providers of the government backed Cycle to Work scheme. If you would like to buy a bike from us using the scheme your employer offers you will need to contact us to discuss the arrangements and eligibility of your purchase. Cycle to Work schemes are a great way to buy a bike and can offer a big saving on the price of your purchase but the ways that each individual scheme operate can vary so it is worth taking some time to find out exactly how your scheme works.
At Summit Cycles we aim to make our part of the process of buying by a Cycle to Work scheme as easy and as simple as possible. We can help you find the right bike and any accessories or extras you will need to make sure you are 100% ready to enjoy your purchased.
The best starting point is to speak with your human resources manager or the person responsible for administering the scheme your employer offers to find out who the provider is and the terms and conditions of the scheme they offer. You can often begin the application process by registering directly with the provider, often via their website. Many providers will ask us to provide a quote for the purchase so this is when you will need to speak to us to check eligibility and of course availability of your chosen bike but our staff can help you make the best choice, guiding you to the right bike and accessories and then raising the information you will need.
Processing can take a little time but often we can secure the bike you want with the payment of a deposit, refundable when the scheme provider issues confirmation certificate or payment.
We do not currently offer to ship bikes purchased via our website, these must be collected from our store. If you see a bike that you are interested in and are unable to collect from us then it may still be worth getting in touch with us to explore further options.
Bikes purchased via our website will be made ready for store collection. This can take a few days depending on where the bike is located. Some bikes will need to ship from a supplier but if this is the case the expected lead time for delivery to us will be displayed on our site. We also hold stock at an off-site storage location and transfer can take a day or so. When we have the bike it will be scheduled for assembly and safety checks with one of our CYTEC mechanics. Once this is complete we will send a final confirmation that the bike is ready for collection and you can then visit the store to pick it up.
With bike purchases, a member of our team will usually contact you prior to processing to check sizing and other details. For bikes in our stock the process from order to collection usually takes 3 or 4 working days but can be quicker sometimes or longer if the bike is shipping to us from a supplier. A member of our team will be able to give you more information if required.
Once your new bike is ready for collection we will get in touch with you to arrange a convenient time for pickup. Collection is from our store at 65 North Parade, Aberystwyth. When you come to collect we may ask for you to present proof of identity for security reasons. A member of staff will check size and personal adjustments like saddle height and can provide advice on care and service arrangements so please allow a little time for the handover process.
