Product Information

Full details

The Trek Powerfly FS+ 5 Gen 4 is a high-performance, full-suspension electric mountain bike designed for trail enthusiasts who demand comfort, traction, and extended range on rugged terrain. Featuring a robust Alpha Platinum Aluminum frame, 130mm/120mm RockShox suspension, and a long-lasting 800Wh battery, it excels at smoothing out technical trails and enabling long-distance off-road adventures; however, its heavy-duty design means it is less agile and more difficult to transport than lighter, non-electric mountain bikes.

FAQs

What is the primary terrain for this bike?

This bike is optimized for off-road trails, singletrack, and mountainous terrain where suspension and electric assist are most beneficial.

How long does it take to charge the 800Wh battery?

Charge times vary based on the charger model used, but typically take several hours; consult your specific Bosch charging manual for estimates.

Can I upgrade the suspension components?

Yes, the frame is compatible with many aftermarket 130mm front and 120mm rear suspension components, but professional installation is recommended.

Is the bike waterproof?

While it is weather-resistant and can handle rain and muddy trails, it should not be submerged in water or cleaned with high-pressure jets.

How often should I service the e-bike motor?

Bosch systems are highly reliable, but it is recommended to have your local dealer perform an inspection and firmware update at least once a year.

Troubleshooting

Motor assistance feels intermittent

Check that the speed sensor magnet is properly aligned and clean the sensor area of any dirt or metal shavings.

Battery will not charge

Ensure the charging port is clear of debris and the charger is firmly seated in both the wall outlet and the battery port.

Brakes feel 'spongy'

The hydraulic lines likely require a bleed to remove trapped air bubbles; consult a professional technician.

Setup, Compatibility & Care

Proper setup is vital to getting the most out of your Powerfly. Start by setting your 'sag' on the RockShox suspension according to your body weight to ensure the bike handles correctly. Regularly check the tire pressure to match the terrain and your riding style. Regarding care, keep the drive unit and battery contacts clean and free of debris. Always ensure the battery is securely locked before riding. When cleaning, avoid using high-pressure water near the electrical components or motor area to prevent water ingress. Schedule annual check-ups with an authorized Trek dealer to ensure the firmware for the Bosch system is updated and the mechanical parts, such as the drivetrain and pivot points, are serviced correctly.
