Parts

Specs are for the stock bike as sold; check your own bike before you buy. Two generations share the Allant+ name. The Gen 2 Allant+ 7 and 7S use the Bosch smart system (BES3). The earlier Allant+ 7, 7S, 8, 8S, 9, 9S, 9.9 and 9.9S use the older Bosch system with a Performance Line CX motor, or Performance Line Speed on the S models; see Bosch motors explained. Smart system and older Bosch parts don't mix, so find your generation first.

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 remote. Battery and motor service on the Bosch system is dealer work: a Bosch dealer reads faults with its diagnostic tool.

Parts list

Tire: Gen 2 Allant+ 7 and 7S take up to 27.5 x 2.4 inch, with or without fenders. Hubs are 100 x 5 mm front and 135 x 5 mm rear.
Brake rotor: Gen 2 frames use post mount brakes and take rotors up to 180 mm.
Cassette: Gen 2 uses Shimano CUES with a LINKGLIDE cassette, so replace it with a CUES LINKGLIDE part.
E-bike charger: Gen 2 (500 Wh): a 4A charger reaches 50% in 1.8 hours and full in 4.9 hours; a 2A charger takes 3.8 and 7.7 hours. Bosch's smart system charger page covers the 2A and 4A units. Earlier models charge a 500 Wh PowerTube to full in about 4.5 hours and a 625 Wh in about 4.9 hours on the standard charger; match the charger to your Bosch system.
E-bike battery: Gen 2: 500 Wh, rated IP55, upgradable to a larger pack after removing spacer W5252256 and its four M3 x 0.5 x 12 mm bolts; no Range Boost. Earlier models: Bosch PowerTube 500 on the 7, 7S and 8, and PowerTube 625 on the higher trims, in Trek's Removable Integrated Battery mount, with optional dealer-fitted Range Boost (a second 500 Wh pack). Check the Wh on your battery label; Bosch's integrated battery page covers PowerTube packs for both systems.
E-bike display: Gen 2: a Bosch smart system display set up in the eBike Flow app. Earlier models: Bosch Purion on the 7 and 7S; Bosch Kiox on the 8 and up, or the Bosch SmartphoneHub in North America.
E-bike lights: integrated lights that keep running long enough to get home after the battery is empty.

Hex keys: stem, bar, rack and brake bolts.
