Who is it for?

The LVR workshop view

Belt drive and internal gear hub: the District+ 4's winning pair. On this straight-top-tube frame, Trek combines a Shimano Nexus hub with five gears housed inside the rear wheel and a Gates CDX belt in place of the chain. With the gears protected inside the hub, there is no derailleur sticking out under the bike; the belt, for its part, doesn't rust and needs no grease. The table below shows where this choice sits among the three drivetrains in the District+ range.

	Nexus 5 + chain	Nexus 5 + Gates CDX belt	Enviolo + Gates CDX belt
How it works	5 gears in the hub, conventional chain	5 gears in the hub, toothed belt	Continuously variable, no steps
Maintenance	Chain needs cleaning and lubing	No grease or regular cleaning	No grease, sealed hub
Reference bike	District+ 4 Guard / Coaster Lowstep	District+ 4, 4 Lowstep, Coaster Belt	District+ 5 and 5 Lowstep
What it means	Simple, common parts	Clean and quiet every day	The finest gear progression

In other words: the District+ 4 is the urban electric bike designed to be ridden every day with no drivetrain maintenance, with a 75 Nm Bosch motor that flattens the hills. Its straight-top-tube frame is aimed at tall riders: XL and XXL here.

An internal gear hub hides its gears inside the rear wheel, sheltered from rain and dust. You can change gear when stationary, at a red light, to pull away in a low gear: that is invaluable in the town centre, where you stop often. With five gears and a 75 Nm motor, the streets climbing up to Saint-Nazaire cathedral are taken without standing on the pedals.

The 545 Wh battery comfortably covers daily use in town; it comes out of the frame so you can charge it at the office or in your flat. Like any e-bike sold in Europe, the Bosch motor stops assisting at 25 km/h. The 2.40-inch Bontrager E6 Hard-Case Lite tyres with reflective sidewalls add comfort and side visibility.

Which District+ should you choose?

Model	Motor	Battery	Drivetrain	Weight (size)
District+ 3	Bosch Active Line Plus, 50 Nm	545 or 800 Wh	Shimano Nexus 8-speed, chain	26.60 kg (L)
District+ 4	Bosch Performance Line, 75 Nm	545 or 800 Wh	Nexus 5-speed, Gates CDX belt	26.20 kg (L)
District+ 4 Lowstep	Bosch Performance Line, 75 Nm	545 or 800 Wh	Nexus 5-speed, Gates CDX belt	25.60 kg (M)
District+ 5	Bosch Performance Line, 75 Nm	545 or 800 Wh	Enviolo Trekking, Gates CDX belt	27.10 kg (L)

Our take: with the same frame and equipment, the 800 Wh version brings 255 Wh more for long journeys; the 545 Wh is enough if you charge every evening. Compared with the District+ 3 (Bosch Active Line Plus, 50 Nm), the District+ 4 gains 25 Nm of torque and the belt drive, for 400 g less in L according to Trek.

LVR sizing advice

This colour is offered in XL (186 to 197 cm) and XXL (196 to 203 cm). The straight top tube means stepping over it: if you often get on the bike carrying a bag or wearing a skirt, also look at the Lowstep version. 175 mm cranks and a 105 mm stem on both sizes.

Size	XL	XXL
Rider height (cm)	186-197	196-203
Inseam (cm)	87-93	92-95
Cranks (mm)	175	175
Stem (mm)	105	105
