Bosch Smart System with 800 Wh Battery

The Trek Powerfly+ 4 features a Bosch electric pedal-assist system paired with an integrated Bosch PowerTube 800 Wh battery.

The battery's high capacity supports longer rides, while actual range depends on assistance level, terrain, rider weight, total load and riding conditions.

The Bosch Smart System provides an integrated electronic platform, while the RIB 2.0 (Removable Integrated Battery) system makes removing the battery from the frame more convenient.

Electric assistance is provided up to 25 km/h, according to the model specifications.

Alpha Platinum Aluminum Frame: Strength and Integration

The frame is built from Alpha Platinum Aluminum, designed to deliver durability and reliability for everyday riding and off-road adventures.

Its construction integrates the RIB 2.0 battery system, guided internal cable routing, a tapered head tube and Motor Armor protection for the motor unit.

The rear triangle features Boost148 spacing with a 12 mm thru-axle, contributing to a solid and reliable frame structure.

SR Suntour XCM 34 Suspension Fork with 120 mm Travel

The SR Suntour XCM 34 suspension fork offers 120 mm of travel to absorb bumps, roots and uneven trail surfaces.

Its air spring, lockout and rebound adjustment allow riders to adapt suspension performance to different riding conditions.

A tapered steerer, Boost110 spacing and a 15 mm thru-axle complete the front suspension setup.

Shimano CUES 10-Speed Drivetrain with LINKGLIDE Technology

The Trek Powerfly+ 4 features a Shimano CUES 10-speed drivetrain, designed to provide smooth gear changes and dependable performance.

The Shimano CUES U6000 GS rear derailleur works with the Shimano CUES LG300 LINKGLIDE 11-48T cassette, providing a wide gear range for climbing and varied terrain.

The FSA Bosch CK-220 crankset with a 36-tooth chainring completes the drivetrain.

27.5" or 29" Wheels Depending on Frame Size

• Size S: 27.5" wheels with Bontrager Montrose Comp 27.5x2.40" tires.

The Powerfly+ 4 features a 780 mm Bontrager Comp aluminum handlebar with a 40 mm rise, designed to provide a stable riding position and confident handling on uneven terrain.

Bontrager XR Endurance Comp lock-on grips offer a secure hold, while the Bontrager Commuter Comp saddle provides comfort for everyday rides.

The 50 mm Bontrager Comp stem is compatible with the Blendr accessory integration system.

203 mm Brake Rotors

The bike is equipped with 203 mm Tektro Centerlock brake rotors, designed to support controlled braking performance on an electric mountain bike.

The frame supports rear brake rotors from 180 to 203 mm. Front rotor compatibility must be checked according to the fork manufacturer's specifications.
