The Trek Powerfly 4 is Trek’s most affordable electric mountain bike. It's built with parts that hold up, like a smooth-shifting 10-speed Shimano drive train, a 500Wh battery and a powerful 250W Bosch motor that assists up to 25km/h. Plus, it features Trek’s user-friendly Removable Integrated Battery (RIB) system that's fully encased in the durable aluminium frame that doesn't require tools for removal. This bike expands your boundaries and lets you travel to destinations that you never thought you'd reach on a mountain bike.

The Powerfly 4 is perfect if 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.

    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.
