Specs are for the stock bike as sold; check your own bike before you buy. This page covers the alloy and carbon Fuel EXe, 140 mm rear and 150 mm front travel. It uses the TQ HPR50 mid-drive; see Fazua and TQ motors explained. An HPR60 upgrade is a dealer job with the TQ dealer service tool. Settings live in the Trek Central and TQ apps.
Electrical parts on this list must match this exact model and are fitted at the external plugs or by a pro. Never open the battery, motor, display or range extender. Battery and motor service on the TQ system is dealer work: a Trek or TQ dealer reads faults with the TQ dealer service tool.
Parts list
- Tire: 29 inch front and rear on every size, up to 29 x 2.5 inch. A 27.5 inch rear wheel (mullet) fits with the Mino Link in the High position.
- Tubeless sealant: every Fuel EXe ships tubeless with rim strips, valves and sealant; top up the sealant on a schedule.
- Brake rotor: 180 mm direct mount rear brake, rotors up to 203 mm. Shimano E-Rotors fit.
- Chainring: 30T to 34T round rings on a 104 BCD, 55 mm chainline, ISIS crank interface. Skip oval rings.
- E-bike charger: TQ charger; the 360 Wh battery charges in about two hours and the range extender in about one.
- E-bike battery: 360 Wh internal TQ battery, 1,835 g; below 10% charge the motor drops to 110 watts. TQ's battery and range extender page covers it. Trek sells the TQ HPR Range Extender Battery (price not shown, read Nov 9, 2026), a 160 Wh, 900 g pack for about 40% more range; fitting it needs power cable 5289576, cable guide W3500001, retention strap 5325177 and four W575056 button head bolts.
- E-bike display: integrated top tube display. AXS bikes add the TQ Smart Box, which powers the SRAM AXS derailleur from the main battery.
- E-bike lights: the Smart Box has front, rear and 12 V aux outputs; a retailer fits the lights.
