TREK POWERFLY 4 GEN 4 BIKE - 2023Powerfly 4 is Trek's most affordable electric mountain bike. It's built with parts that hold up, like a smooth-shifting Shimano drivetrain, and a powerful Bosch motor. Plus, it features Trek's user-friendly Removable Integrated Battery (RIB) system that's fully encased in the frame yet doesn't require tools for removal. This bike expands your boundaries and lets you travel to destinations you never thought you'd reach on a mountain bike.FEATURESRemovable Integrated BatteryBosch Performance Line CX motorBosch LED RemoteBosch eBike Flow appTECH SPECS Frameset*FrameSize: XS , S; Alpha Platinum Aluminum, curved top tube, Removable Integrated Battery (RIB), tapered head tube, Control Freak internal routing, Motor Armor, Boost148, 12mm thru axleSize: M , L , XL; Alpha Platinum Aluminum, Removable Integrated Battery (RIB), tapered head tube, Control Freak internal routing, Motor Armor, Boost148, 12mm thru axle*ForkSize: XS; SR Suntour XCM 34, coil spring, preload, lockout, tapered steerer, 44mm offset, Boost110, 15mm thru axle, 80mm travelSize: S , M , L , XL; SR Suntour XCM 34, coil spring, preload, lockout, tapered steerer, 44mm offset, Boost110, 15mm thru axle, 120mm travelMax compatible fork travel120mm (526mm axle-to-crown), XS & S: 100mm (492mm axle-to-crown) WheelsHub front: Formula DC-511, 6-bolt, Boost110, 15mm thru axleHub rear: Bontrager Approved DC-3248, sealed bearing, alloy axle, 6-bolt, Shimano 8/9/10 freehub, Boost148, 12mm thru axleSkewer rear: Bontrager Switch thru axle, removable leverRim: Bontrager Connection, double-wall, 32-hole, 20mm width, Presta valve*TireSize: XS , S; Bontrager XR3 Comp, wire bead, 30tpi, 27.5x2.35''Size: M , L , XL; Bontrager XR3 Comp, wire bead, 30tpi, 29x2.30''Max tire sizeFrame: 29x2.60" or 27.5x2.8" (XS & S: 27.5x2.60") Fork: See manufacturer DrivetrainShifter: Shimano Deore M4100, 10 speedRear derailleur: Shimano Deore M5120, long cageCrank: FSA Bosch CK-220, 36T ring, 165mm lengthChainring: FSA, 36T, steelCassette: Shimano Deore M4100, 11-46, 10 speedChain: KMC X10, 10 speedPedal: VP-536 nylon platformMax chainring size: 38T ComponentsSaddle: Bontrager Commuter Comp*SeatpostSize: XS , S; Bontrager alloy, 31.6mm, 12mm offset, 330mm lengthSize: M; Bontrager alloy, 31.6mm, 12mm offset, 360mm lengthSize: L , XL; Bontrager alloy, 31.6mm, 12mm offset, 400mm length*HandlebarSize: XS , S; Bontrager alloy, 31.8mm, 15mm rise, 720mm widthSize: M , L , XL; Bontrager alloy, 31.8mm, 15mm rise, 750mm widthGrips: Bontrager XR Endurance Comp, lock-on*StemSize: XS; Bontrager alloy, 31.8mm, Blendr compatible, 7 degree, 50mm lengthSize: S , M; Bontrager alloy, 31.8mm, Blendr compatible, 7 degree, 60mm lengthSize: L , XL; Bontrager alloy, 31.8mm, Blendr compatible, 7 degree, 70mm lengthHeadset: FSA IS-2, 1-1/8'' top, 1.5'' bottomBrake rotor: Tektro, 6-bolt, 203mmBrake Set: Tektro HD-M275 hydraulic discRotor size: Max brake rotor sizes: Front see fork manufacturer, rear 203mm AccessoriesBattery: Bosch PowerTube 500Wh, smart systemCharger: Bosch standard 4A, 110V, smart systemController: Bosch Intuvia 100, smart systemMotor: Bosch Performance Line CX, smart system, magnesium motor body, 85 NmComputer: Bosch LED remote, smart system WeightWeight: M - 23.94 kg / 52.78 lbsWeight limit: This bike has a maximum total weight limit (combined weight of bicycle, rider, and cargo) of 300 pounds (136 kg)Sizing TableFrame size number13.5"15.5"17.5"19.5"21.5"Frame size letterXSSMLXLWheel size27.5"27.5"29"29"29"A Seat tube36.339.441.94752.1Effective seat tube angle70.0deg71.5deg71.7deg71.7deg71.7degC Head tube length1213131416D Head angle65.0deg67.6deg67.7deg67.7deg67.7degE Effective top tube57.959.861.764.167.2F Bottom bracket height32.830.732.432.432.4G Bottom bracket drop3.74.94.955H Chainstay length45.545.545.545.545.5I Offset5.14.25.15.15.1J Trail11.410.19.89.89.8K Wheelbase113.5112.5115.5118121.2L Standover70.672.179.481.681.8M Frame reach35.23940.642.745.2N Frame stack62.162.363.964.866.7
