The Powerfly 7 is an electric mountain bike built to rip with a smooth, powerful Bosch e-MTB system, a durable aluminium frame and a Removable Integrated Battery (RIB) system that fully encases the battery. Its smart system LED remote and Kiox display pair with Bosch's eBike Flow app for activity tracking, Bluetooth connectivity and more. An upgraded RockShox air suspension, 1x12 Shimano drivetrain and dropper post make this the ideal choice for those who want a boost on the climbs so they can get rad on the way down.
You want more than just the added capability of electric-assist. You also want quality mountain bike parts that make the biggest difference on the trail, and an upgraded controller with a smart system and Kiox full-colour screen that gives you Bluetooth connectivity and loads of enhanced ride tracking and fitness features.
A durable aluminium frame with a user-friendly Removable Integrated 625 Wh battery for great aesthetics and protection on the trail, a Bosch Performance CX motor that assists up to 20 mph (25 km/h in Europe), smart system LED remote and a Kiox display. Plus, a RockShox 35 Gold RL fork, a 1x12 Shimano SLX and XT drivetrain, 4-piston hydraulic brakes, Bontrager Line Comp 30 tubeless-ready wheels and a dropper post.
If you're picky about your parts, you want Powerfly 7. You get wider wheels for better traction and stability, a stiffer fork for more precise steering and a refined Shimano drivetrain that gives you smoother shifting with a lighter touch.
- The Powerfly Gen 4 features Bosch's smart system with an LED remote that connects to the Bosch eBike Flow app for over-the-air system updates, customised motor tuning and more
- 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 to remove the battery without tools and lets you mount a water bottle cage
- The full-colour Kiox 300 display gives you ride info, connects with Bluetooth®-enabled devices and has a built-in theft prevention feature
- The dropper post lets you lower your saddle on the fly so it's out of the way on descents and easier to dismount
- 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.

The UK’s Cycle To Work Scheme has been in place for over 20 years now, offering fantastic discounts to tens of thousands of riders.
The Cycle To Work Scheme, is offered through many thousands of employers in the UK and applies to bikes of all types, whether it’s road, MTB or hybrid, and that includes e-bikes too.
Introduced in 1999, the scheme aims to encourage employees to commute on their bike for environmental, traffic congestion and health reasons. It also enables companies to demonstrate that they’re looking after the wellbeing of their people.
Obviously, you’re supposed to use the bike for commuting – and we are massive supporters of getting to work this way – but it’s fine to buy a bike that’s built for the trails. Your employer owns the bike until you pay the final ownership fee, which is based on the “fair market value” of it at the end of that period.
As well as your new bike, you can use the scheme to buy accessories, such as helmets and bags, though these have to be ostensibly for your commute. So, no full face masks, for example. If you don’t have a lock, we strongly advise that you get one along with your bike as you’re liable for the Cycle To Work payments, even if it gets stolen while you’re paying it off.
This is a salary sacrifice scheme for people aged 18 and over where the monthly payment for your bike is taken out before tax and National Insurance are deducted. Because your contribution is taken before tax, you pay off more per month for less. So, for a bike costing £1,200, £100 is taken from your salary every month but it only costs you £68 because the other £32 would have normally gone to the tax man, right? So, you pay 12 instalments of £68 and a final ownership fee of £300, totalling £1,116. If your salary puts you in the higher tax brackets, you actually save more but you get the gist.
Firstly, find out which scheme your employer is enrolled in and therefore where you can buy your bike from. We work with a number of Cycle To Work providers, including cyclescheme.co.uk, cycleplus and Bikes for the NHS.
Then you need to speak to your HR department and request a certificate, bring it to us and we’ll redeem it against the cost of your bike and accessories. The salary sacrifice commences from your next pay packet.
To get a bike on the scheme, your employer needs to sign up to a provider. If they’re unsure about how to do this, send them to us and we’ll help.
If you can find it cheaper - let us know!
As well as offering a fantastic range of cycling equipment, Big Bear Bikes is equally committed to offering great value.
