Who is it for?

For the rider used to conventional bikes who's switching to electric and wants to keep a derailleur, for short, brisk rides. It will suit anyone who enjoys pedalling and uses the assistance as a top-up.

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.

With a derailleur, you change gear while pedalling, without easing off: you keep a steady cadence, which also helps the Bosch motor work in its best range. The 11-46 Linkglide cassette covers a wider spread than the Nexus 7-speed hub, useful whenever the route alternates between flat stretches and ramps.

The 50 mm Bontrager Girona Comp tyres have a puncture-protection layer under the tread and a reflective strip on the sidewall. They roll efficiently on tarmac and keep enough volume for comfort on rough streets.

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: at 26.40 kg in L, the R9 360 is lighter than the hub-geared N7 360 (26.80 kg). If you want the same drivetrain with more range, the R9 540 brings 180 Wh.

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
