The Powerfly 4 625 takes Trek's most affordable electric mountain bike and gives it a boost with a longer-range 625 watt-hour battery. Of course, you still get the user-friendly Removable Integrated Battery (RIB) system that's simple to remove and install, plus all the other parts that make Powerfly 4 an 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 display with LED remote, a 1x9 Shimano CUES drivetrain and a suspension fork with lockout. Plus, Smart Wheel Sizing means that riders of every size get a great fit – 29˝ wheels on larger frames, 27.5˝ wheels on smaller frames.

This model gives you a longer range battery than the standard Powerfly 4, so you’ll never be short on fun.

Please Note: Sizes S and XS are provided with a curved top tube for improved stand-over height.

    View All FAQ's
    How does the DASH Store work?

    At DASH, we've created a Cycle to Work enabled storefront which allows you to browse and order a range of items, all whilst benefitting from savings of 28-47%. The cost of items you order is split into 12 months and deducted from your gross (or pre-tax) salary, allowing you to save on income tax and national insurance contributions, which is called salary sacrifice. After 12 months, you'll be able to continue using your items at no extra cost.

    What items are available on DASH Store?

    We have a range of items, from bikes and e-bikes, to accessories (such as helmets and locks), bike parts and tools, clothing (including jackets, shorts, shoes, and everything in between), even pre-owned bikes. We work with a range of brands so there's sure to be something you like in stock.

    Can I use other Cycle to Work scheme vouchers on DASH Store?

    Since we are a Cycle to Work scheme ourselves, we cannot accept vouchers from other scheme providers. If you would like to use DASH and already have a voucher, it might be worth speaking to your employer to see if they are able to refund it.
