Specs are for the stock bike as sold; check your own bike before you buy. This page covers the current District+ 1 and District+ 2, step-over and low-step, on 27.5 inch wheels. Earlier District+ models used different parts, so match yours first. The District+ 1 runs a Bosch smart system Active Line motor (40 Nm) and the District+ 2 a Performance Line motor (50 Nm); see Bosch motors explained. Both shift with a Shimano Nexus 7 internal gear hub.
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: Bontrager H2 Comp, 27.5 x 2.0 inch. The rims and tires are not tubeless ready.
- Inner tube: match the 27.5 x 2.0 inch tire; this bike runs tubes.
- Disc brake caliper: Shimano MT200 hydraulic, front and rear. See the Shimano BR-MT200 caliper page; it takes 160 or 180 mm rotors and uses Shimano mineral oil.
- Disc brake pads: the MT200 caliper takes Shimano B05S-RX resin pads only.
- E-bike display: Bosch smart system LED Remote on the bar.
- E-bike battery: Bosch smart system CompactTube 400 (400 Wh), built in and not removable by the rider; a certified Trek mechanic removes it. Bosch's integrated battery page covers the CompactTube 400. In some markets a Bosch PowerMore 250 kit adds 250 Wh on the down tube.
- E-bike lights: integrated head and rear lights.
- Saddle: the District+ 1 takes a 31.6 mm suspension seatpost (Trek part 554223 or 554225); the District+ 2 has one stock.
Tools for common jobs
- Hex keys: stem, bar, seatpost and caliper bolts.
- Tire levers: fitting a new tube.
- Floor pump with gauge: setting pressure within the sidewall range.
- Torque wrench: caliper and stem bolts, to the values on the part.
- Brake pad spreader: pushing the MT200 pistons back before new pads.
- Brake bleed kit: bleeding the Shimano MT200 with Shimano mineral oil when the lever feels soft; see bleed Shimano brakes.
- Chain checker: catching chain wear early.
- Chain lube: after cleaning and wet rides.
