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 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.
| 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.
