Who is it for?

For anyone who lives up the hill, near Saint-Nazaire cathedral or in the steep neighbourhoods, and wants to ride home effortlessly every day. It's for those who want maximum power and minimum maintenance.

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.

With 75 Nm, the Performance Line pulls away strongly, even from a standstill on a hill: the bike sets off without hesitation at the lights at the top of a ramp. The Nexus C7000 5-speed hub offers a low gear for climbs and a high gear for the avenues; the motor bridges the gap between them.

The Gates CDX belt is designed to handle high torque: it transmits the motor's push without stretching or wearing quickly, and never needs any grease. The 34-tooth sprocket and the sealed hub make up a drivetrain that fears neither rain nor dust.

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: the N5 B weighs 500 g more than the N7 B (27.70 kg versus 27.20 kg) but brings the 75 Nm motor and the PowerTube 600. If you prefer a derailleur, the R10 offers the same motor for 26.30 kg.

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
