For the urban rider who wants an electric bike with no surprises: hand brakes like on any bike, a freewheel that lets you turn the pedals backwards, and a chain that any workshop can service. Ideal for daily journeys and shopping.
Chain and freewheel: the classic version of the District+ 4. The District+ 4 Guard Lowstep pairs a Shimano HG40 chain with a 27-tooth Nexus sprocket; the five-speed internal gear hub and the freewheel are those of an ordinary city bike. No coaster brake here: the two Shimano MT200 hydraulic disc brakes do all the work, as on a classic city bike.
| Nexus 5 + chain | Nexus 5 + Gates CDX belt | Enviolo + Gates CDX belt | |
| How it works | 5 gears in the hub, conventional chain | 5 gears in the hub, toothed belt | Continuously variable, no steps |
| Maintenance | Chain needs cleaning and lubing | No grease or regular cleaning | No grease, sealed hub |
| Reference bike | District+ 4 Guard / Coaster Lowstep | District+ 4, 4 Lowstep, Coaster Belt | District+ 5 and 5 Lowstep |
| What it means | Simple, common parts | Clean and quiet every day | The finest gear progression |
In other words: the District+ 4 Guard Lowstep is the most conventional version of the step-through District+ 4, for those who want the 75 Nm motor and the Nexus hub without a belt or coaster brake.
Unlike the Coaster versions, the District+ 4 Guard keeps a freewheel: you can turn the pedals backwards to position them before setting off, as on a conventional bike. Braking relies entirely on the two 160 mm Shimano MT200 hydraulic discs, powerful and easy to modulate with your fingertips.
The five-speed Nexus C7000 internal gear hub needs no derailleur and lets you change gear when stationary. The 75 Nm Bosch motor provides strong assistance when pulling away and on climbs, within the 25 km/h legal limit. The adjustable, Blendr-compatible stem takes a phone holder or a light.
| Model | Motor | Battery | Drivetrain | Weight (size) |
| District+ 4 Lowstep | Bosch Performance Line, 75 Nm | 545 or 800 Wh | Nexus 5-speed, Gates CDX belt | 25.60 kg (M) |
| District+ 4 Coaster Belt Lowstep | Bosch Performance Line, 75 Nm | 545 or 800 Wh | Nexus 5 with coaster brake, belt | 26.00 kg (M) |
| District+ 4 Coaster Lowstep | Bosch Performance Line, 75 Nm | 545 or 800 Wh | Nexus 5 with coaster brake, chain | 26.00 kg (M) |
| District+ 4 Guard Lowstep | Bosch Performance Line, 75 Nm | 545 or 800 Wh | Nexus 5-speed, chain | 26.00 kg (M) |
Our take: at 26.00 kg in M, the Guard has the same Trek weight as the Coaster models; it stands out for its freewheel and 100% hand-operated braking. The 800 Wh version adds 255 Wh at the same published weight; the belt-driven District+ 4 Lowstep comes down to 25.60 kg.

LVR sizing advice Offered from S (155 to 165 cm) to XL (186 to 197 cm). The S and M have 170 mm cranks and an 85 mm stem; from L upwards, 175 mm and 105 mm. The adjustable stem then lets us raise the handlebar or bring it closer by a few centimetres in the workshop.
