Who is it for?

For families or individuals who do their shopping by bike, carry heavy panniers and want an e-bike that can do it all in town. It will suit anyone who rides every day, in all weathers.

The LVR workshop view

Performance Line and CDX belt: the most muscular District+. The Bosch Performance Line motor delivers 75 Nm of torque, considerably more than the Active Line Plus on the District+ 3: it gives a stronger push when pulling away and holds your pace on steep climbs. To handle this torque, Trek fits a Gates CDX belt, Gates's heavy-duty range, on a five-speed Nexus C7000 hub. Five gears are enough here, because the motor bridges the gaps between them.

	Active Line Plus	Performance Line	What it means
Torque	60 Nm (Trek figure)	75 Nm	Punchier acceleration
Feel	Gentle, natural assistance	Strong push	Steep climbs without straining
District+ models concerned	District+ 3 N7 and R9	District+ 4 N5 B and R10	Top of the 2027 range
Battery	360 or 540 Wh	PowerTube 600	More energy available

In short: the N5 B combines the most powerful motor in the series, the big battery and the drivetrain that needs the least care. It's the District+ for intensive use, loaded or in hilly terrain.

Loaded with two full panniers, a city bike needs strength when pulling away: that's where the 75 Nm of the Performance Line makes the difference compared with a gentler motor. The Nexus hub lets you shift down at a standstill before setting off loaded, without jolting the drivetrain.

The MIK-compatible rack takes baskets and panniers that clip on and off in one movement so you can take them into the shop. The Pletscher Comp Flex 18 kickstand holds the bike while you load it, and the Shimano hydraulic brakes keep braking consistent even with weight at the rear. Above 25 km/h, the assistance cuts out.

Which District+ should you choose?

Model	Motor	Battery	Drivetrain	Weight (L)
District+ 3 N7 B LS	Bosch Active Line Plus	540 Wh	Nexus 7-speed hub, Gates belt	27.20 kg
District+ 4 N5 B LS	Bosch Performance Line	600 Wh	Nexus 5-speed hub, Gates belt	27.70 kg
District+ 4 R10 LS	Bosch Performance Line	600 Wh	CUES 10-speed derailleur	26.30 kg
District+ 3 N7 540 LS	Bosch Active Line Plus	540 Wh	Nexus 7-speed hub, chain	27.70 kg

Our take: for carrying loads, the N5 B combines the highest torque in the series with a robust drivetrain. The R10, with the same motor, saves 1.40 kg (26.30 kg) but means maintaining a derailleur.

LVR sizing advice

Four sizes cover riders from 147 to 203 cm. For an upright, relaxed ride in the town centre, go for the smaller size if you're unsure; for long rides, the larger size gives your legs more room. The L and XL get a 110 mm stem, compared with 70 mm on the S and M.

Size	S	M	L	XL
Rider height (cm)	147-155	155-173	170-185	185-203
Inseam (cm)	69-88	77-96	80-99	86-105
Stem (mm)	70	70	110	110
