Trek Powerfly FS 9 Equipped Electric Mountain Bike 2022

Comfortable, fast, and efficient - the Trek Powerfly FS 9 Equipped Electric Mountain Bike is highly versatile and suited to various riding styles, whether it's a daily commute or racking up the singletrack miles. With a powerful Bosch motor system and 100mm of rear suspension, the bike combines comfort with efficiency and functionality.

With a durable aluminium frame and high-end Shimano components, the Powerfly is a reliable option to get you from A to B. The downtube neatly conceals a removable Bosch PowerTube 625Wh battery, that packs enough power for all-day riding and is chargeable both on and off the bike. It utilises a compact Bosch Performance CX motor providing 250 watts of climb-crushing power for assistance up to a maximum speed of 15.5 mph / 25 km/h, while the onboard SmartphoneHub computer features a walk-assist setting, making it easy to manoeuvre in off-bike situations.

A 12-speed Shimano Deore XT drivetrain offers a wide range of gears, and powerful hydraulic brakes provide ample stopping power both on and off-road.

This equipped edition focuses on everyday riding and comes pre-fitted with essential ride accessories to improve your ride experience. Mudguards help to defend against road spray and splatter, keeping you dry for the duration of your ride. Front and rear lights help improve visibility in low-light situations, utilising power from the battery to ensure simple charging. A rear pannier rack and stand add daily convenience, while a dropper seatpost adds flow on mixed gradient trail rides.
