Who is it for?

For the rider who alternates shopping trips in town with Sunday rides on the Passa Païs greenway, between Bédarieux and the Hauts Cantons, driving to the start or riding there. It will appeal to anyone who wants a versatile, nimble bike rather than a touring bike.

The LVR workshop view

The CUES derailleur: the gear spread of a touring bike. Shimano CUES uses Linkglide technology: sprockets with thicker teeth and a dedicated chain, designed to handle the torque of an electric motor and last longer. The nine-speed 11-46 cassette offers a wider spread than an urban hub: a very low gear for pulling away on a hill, a high gear for riding fast on the flat.

	Nexus hub + chain	Nexus hub + Gates belt	Shimano CUES derailleur
How it works	Gears hidden in the rear hub	Gears in the hub, carbon belt	External sprockets and derailleur
Shifting	Possible at a standstill, at red lights	Possible at a standstill, at red lights	While pedalling, smoothly
Maintenance	Low, chain to grease	Very low, no greasing	Regular: cleaning, adjustment
Who for	Simple urban journeys	Everyday use without the grime	Varied terrain, sporty rides

In short: the R9 360 is the most affordable District+ 3 with a derailleur. It suits anyone who wants a wide gear range for hills and leisure rides, with a compact 360 Wh battery.

The greenway follows a former railway line: gentle but long gradients, where the close spacing of the 9-speed derailleur lets you find exactly the right gear. The Active Line Plus motor provides natural assistance, which you adjust from the bar via the Purion 200 control to make the 360 Wh battery last.

The MIK-compatible rack takes a pannier with a picnic and a windproof, and the Pletscher kickstand steadies the bike when you stop at a viewpoint. The Girona Comp tyres and their puncture-protection layer limit nasty surprises on gravelly sections. The motor stops assisting at 25 km/h, after which you pedal freely.

Which District+ should you choose?

Model	Motor	Battery	Drivetrain	Weight (L)
District+ 3 N7 360 LS	Bosch Active Line Plus	360 Wh	Nexus 7-speed hub, chain	26.80 kg
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+ 4 R10 LS	Bosch Performance Line	600 Wh	CUES 10-speed derailleur	26.30 kg

Our take: for rides of a few hours, the R9 360 and its 26.40 kg are a good fit. For full-day rides, the R9 540 adds 180 Wh without changing the drivetrain.

LVR sizing advice

The Lowstep frame is chosen mainly by the rider's height: S covers 147 to 155 cm, M 155 to 173 cm, L 170 to 185 cm and XL 185 to 203 cm. Between M and L, the M brings the bar closer and feels reassuring in town, while the L stretches the position for longer rides; the stem goes from 70 to 110 mm in L and XL.

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

Is the red bright?	It's a deep, warm red that stands out well in the countryside.
