What is the Trek Powerfly+ Gen 5?

The Trek Powerfly+ Gen 5 is a capable electric hardtail mountain bike designed to be efficient, confidence-inspiring and versatile for everything from bridleways and trail centres to longer mixed-terrain rides.

Who is the Powerfly+ best for?

Powerfly+ is a great choice if you want the direct feel and simplicity of a hardtail with powerful e-MTB assistance. It suits riders who want a do-it-all electric mountain bike for off-road exploring, fitness rides, commuting links and everyday versatility.

What motor system does the Powerfly+ use?

Powerfly+ models use the Bosch Performance Line CX drive system (Bosch smart system). Exact display and battery specification can vary by model, so check the product specification for the bike you’re considering.

How fast does the motor assist?

UK and EU e-MTBs provide motor assistance up to 25 km/h (15.5 mph). You can ride faster under your own power beyond the assistance limit.

How far can I ride on a Powerfly+?

Range depends on the battery size, support mode, rider weight, terrain, tyre choice and weather. If you tell us your typical riding (distance, elevation and surface), we can help you choose the best setup for your routes.

Do some Powerfly+ bikes come with an 800Wh battery?

Some Powerfly+ variants are offered with a larger-capacity 800Wh battery for extended rides. Battery specification varies by model, so check the product page details for the exact configuration.

What is the difference between Powerfly+ and Powerfly FS+?

Powerfly+ is a hardtail (front suspension only) for a more direct feel and lower-maintenance simplicity. Powerfly FS+ adds rear suspension for extra comfort and control on rougher, more technical terrain.

What does “Equipped” mean on Powerfly+ models?

“Equipped” versions are built with practical accessories for everyday riding. Exact accessories can vary, so refer to the specification on the product page for what’s included on that model.

Is the Powerfly+ suitable for commuting and touring?

Yes. Powerfly+ works brilliantly for mixed riding that includes lanes, bridleways and longer days out. Equipped models add extra practicality for everyday use, and all models benefit from Bosch e-bike support for easier longer-distance riding.

Can you help me choose the right size?

Yes. We’re happy to recommend sizing based on your height, inseam and riding style. If you’re local, you can also visit us in Midhurst for in-person advice.

Do you build and check the bike before delivery?

Yes. Every bike is built and checked by our workshop before collection or delivery. We can also help with setup advice to make sure it’s dialled for your riding.

Do you provide warranty support and servicing?

Yes. We provide UK-based aftercare, workshop servicing and support for your Trek e-bike, including help with Bosch diagnostics and routine maintenance.

The Trek Powerfly+ 4 800Wh Gen 5 takes the same capable hardtail platform and adds a higher-capacity battery for riders who want to go further between charges. It’s built for longer adventures, commutes and all-day exploring.

The larger battery boosts range without changing the bike’s easy, confidence-inspiring ride feel, making it ideal for riders who prioritise distance and convenience.

IT’S RIGHT FOR YOU IF…

You want the versatility of the Powerfly+ 4 but need maximum range for longer rides, touring or regular use where charging opportunities are limited.

This model suits riders who value flexibility and endurance over outright trail aggression.

THE TECH YOU GET…

An Alpha Platinum Aluminium hardtail frame combined with the Bosch Performance Line CX motor and 800Wh battery delivers smooth, powerful assistance with extended range.

Front suspension, reliable gearing and strong hydraulic disc brakes round out a practical, long-distance-ready build.

THE FINAL WORD…

The Powerfly+ 4 800Wh is all about range and usability. If you’re weighing up battery options or models, our Powerfly Buyer Guide breaks down the differences clearly.
