Description
The Trek Powerfly FS+ 4 is a full-power full suspension electric mountain bike for taking on alpine adventures. It features 130 mm of front and 120 mm of rear trail-smoothing travel and a powerful Bosch Performance Line CX motor with a PowerMore compatible Removable Integrated Battery 2.0 (RIB 2.0) for getting far, far out there.
Powerfly FS+ 4 features an Alpha Platinum Aluminium frame with a Bosch Performance Line CX motor (85 Nm, 250 W), a 600 Wh PowerTube RIB 2.0 removable integrated battery and Purion 200 controller. 130 mm front and 120 mm rear suspension from a RockShox Recon Silver RL fork with Solo Air spring and Motion Control damper and a RockShox Deluxe Select shock. Tubeless-ready wheels with puncture-resistant 2.4? tyres, a 10-speed Shimano CUES drivetrain for clean shifts, a Bontrager Line dropper post and hydraulic disc brakes.
Explore the beyond with Powerfly FS+ 4. This capable and powerful e-MTB is ready to keep you soaring up the trail with a grin as big as you have on the downs. Its capable full-suspension set-up smooths rough tracks and boosts confidence while you venture to alpine yurts or just around town.
Please note: This model features tubeless ready wheels and tyres which offer a superior ride and less rolling resistance than traditional innertubes. This system requires tyre sealant to function correctly and this will be fitted in our workshop prior to despatch. The nature of this sealant means that the tyre may not be fully sealed until it has been ridden a short distance and therefore the bicycle may arrive with reduced pressure in the tyres. Please check the bicycle's tyres are inflated to the recommended pressure before cycling.
Please note: This model offers electric assistance up to speeds of 25kph (15.6mph).
IMPORTANT: This bicycle requires a suspension pump to set and tune its suspension correctly. This is not included as standard.

Sizing information is provided as a general guide only. This is based on the average rider riding the bicycle in the style for which it is intended. This takes no account of a rider's personal proportions, physique, flexibility and biomechanics. If your height places you on, or near, a bicycle size step then we recommend you consider both sizes. All bicycles offer a range of handlebar and saddle adjustment which will enable you to fine tune your riding position once the correct size has been established. If you are unsure on sizing, we strongly recommend you visit our store so we can assist you. Pedal On offers advice and information on sizing in good faith, the final decision and responsibility on which size to purchase is yours.
