Who is it for?

For the commuter who rides ten kilometres or more to get to work, between Béziers and the neighbouring towns. It will suit anyone who wants to replace the car during the week and keep an enjoyable bike for the weekend.

The LVR workshop view

Nine speeds and 540 Wh to get out of town. This District+ combines the range's mid-sized battery with the Shimano CUES derailleur drivetrain. The 50 mm Bontrager Girona Comp tyres, with a puncture-protection layer under the tread, roll well on tarmac and handle hard-packed tracks. The Active Line Plus motor provides progressive, jolt-free assistance, appreciated when riding in a group.

	E6 Hard-Case Lite tyre	Girona Comp tyre	What it means
Fitted to	District+ N5 B, N7, N7 B	District+ R9, R10	Depending on the drivetrain chosen
Size	700x50	700x50	Same air volume, same comfort
Protection	Hard-Case Lite casing	Puncture-protection layer under the tread	Fewer stops for broken glass
Visibility	Reflective sidewalls	Reflective strip	Visible from the side at night

In short: the R9 540 is aimed at riders who alternate commuting with rides lasting several hours. It keeps the 11-46 gear range of the R9 360 and adds 180 Wh of reserve.

On a long commute, the derailleur lets you keep a constant cadence when the terrain changes, and the Active Line Plus motor gives you a hand without draining the 540 Wh battery. The system assists you up to 25 km/h, the legal speed for e-bikes; on the flat, you can go faster under your own steam.

The Girona Comp tyres with puncture protection reduce the risk of an unexpected stop on the way to the office, and their reflective strip makes you visible from the side when you ride home after dark in winter. The SKS mudguards keep your work clothes dry after a shower.

Which District+ should you choose?

Model	Motor	Battery	Drivetrain	Weight (L)
District+ 3 R9 360 LS	Bosch Active Line Plus	360 Wh	CUES 9-speed derailleur	26.40 kg
District+ 3 R9 540 LS	Bosch Active Line Plus	540 Wh	CUES 9-speed derailleur	24.30 kg
District+ 3 N7 540 LS	Bosch Active Line Plus	540 Wh	Nexus 7-speed hub, chain	27.70 kg
District+ 4 R10 LS	Bosch Performance Line	600 Wh	CUES 10-speed derailleur	26.30 kg

Our take: for a long commute, the R9 540 offers the mid-sized battery and the lowest weight quoted by Trek (24.30 kg in L). If your route is very hilly, the R10 and its 75 Nm accelerate more briskly.

LVR sizing advice

Thanks to the low step-over, the top tube height hardly matters: go by your height. S for 147 to 155 cm, M for 155 to 173 cm, L for 170 to 185 cm, XL for 185 to 203 cm. If you're on the M / L borderline, try both in the shop: the 110 mm stem on the L stretches the position noticeably.

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

Your questions

Can I go faster than 25 km/h?	Yes, by pedalling, but without help from the motor beyond that.
Are the tyres puncture-resistant?	The Girona Comp tyres have a puncture-protection layer under the tread.
Where can I put my things?	In a pannier on the MIK-compatible rack.
Is the black visible?	The reflective strips on the tyres improve side-on visibility.
