Replacement parts and specs for the Trek Verve+ 3 Gen 3 and Verve+ 4S Gen 3 comfort e-bikes: 27.5 x 2.4 tires, quick release hubs, Bosch smart system 545 Wh battery and 4A or 2A charger.

Specs are for the stock bike as sold; check your own bike before you buy. This page covers the Gen 3 Verve+ 3 and Verve+ 4S, step-over and low-step. Both use a Bosch smart system mid-drive built into the frame; see Bosch motors explained. The Verve+ 4S adds a 63 mm travel suspension fork. Earlier Verve+ models rode on 700 x 50 mm tires and used different parts, so check your generation on the frame label before you order.
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: 27.5 x 2.4 inch, which is also the largest size the frame takes, with or without fenders.
- Inner tube: match the 27.5 x 2.4 inch tire. The hubs are quick release, 100 mm front and 135 mm rear, so the wheels come off without tools.
- E-bike charger: Bosch standard charger. With a 4A charger the 545 Wh battery 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.
- E-bike battery: 545 Wh Bosch battery in a magnetic enclosure at the top of the down tube, rated IP55. The Verve+ 4S frame takes 400, 545, 725 and 800 Wh packs; the 725 and 800 Wh packs need the taller battery cover, Trek SKU W5280748. The Verve+ 3 also takes a larger pack with a larger cover. Neither works with Range Boost. Match the Wh on your battery label before you order; Bosch's integrated battery page covers its smart system packs.
- E-bike display: Bosch smart system remote with five green battery LEDs and four assist levels (Eco, Tour, Sport, Turbo), set up in the Bosch eBike Flow app.
- E-bike lights: integrated lights, wired to the main battery.
Tools for common jobs
- Hex keys: stem, bar, seatpost and rack bolts.

- Floor pump with gauge: setting pressure in the 2.4 inch tires.
