Who is it for?

For couples where one is fitter than the other: the assistance lets you ride together without waiting. It's also for riders who often face the wind, tramontane or sea breeze, on the flat roads of the Béziers plain.

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.

Into the wind, the real enemy of coastal cyclists, the Active Line Plus motor provides progressive assistance that stops you wearing yourself out, and the 540 Wh battery goes the distance when you need to stay in a higher mode for longer. With a lower gear, you keep an easy cadence despite the gusts.

When riding as a pair, set the assistance so the less trained rider can keep up without overdoing it. The Purion 200 control lets you change mode with your thumb, without letting go of the bar, and the step-through frame makes stopping and starting at junctions simple.

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 riding into the wind for long periods, the 540 Wh battery of the R9 540 makes the difference compared with the R9 360. If you want more torque, the R10 gets the 75 Nm Performance Line and a PowerTube 600 battery.

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 ride alongside someone on a non-electric bike?	Yes, the assistance can be set to match an unassisted rider.
What about the tramontane?	Choose a higher mode and a lower gear to keep an easy cadence.
How do I change mode?	With your thumb, on the Purion 200 control next to the grip.
Is the red a dark shade?	Yes, it's a deep burgundy, elegant and warm.
