For the tall commuter who lives in a village around Béziers, such as Sérignan, Villeneuve-lès-Béziers or Maraussan, and rides into town every day on roads exposed to the wind. The large battery means fewer charges and lets you keep a high level of assistance when a headwind picks up.
Belt drive and internal gear hub: the District+ 4's winning pair. On this straight-top-tube frame, Trek combines a Shimano Nexus hub with five gears housed inside the rear wheel and a Gates CDX belt in place of the chain. With the gears protected inside the hub, there is no derailleur sticking out under the bike; the belt, for its part, doesn't rust and needs no grease. The table below shows where this choice sits among the three drivetrains in the District+ range.
| 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 is the urban electric bike designed to be ridden every day with no drivetrain maintenance, with a 75 Nm Bosch motor that flattens the hills. Its straight-top-tube frame is aimed at tall riders: XL and XXL here.
With 800 Wh, you get 255 Wh more than the 545 Wh version: enough for the return trip several days in a row, or to ride more often in the higher assistance modes. We don't quote a range figure, as it depends on the wind, terrain, the load carried and the mode chosen; Bosch offers an online calculator to estimate yours.
On a daily commute, the Gates CDX belt really shows its worth: no chain rusting in winter, no stained trousers, and almost no noise. The Bosch Intuvia 100 display shows speed, mode and remaining charge. The assistance stops at 25 km/h, as European e-bike rules require; beyond that, the Nexus hub lets you pedal freely.
| Model | Motor | Battery | Drivetrain | Weight (size) |
| District+ 3 | Bosch Active Line Plus, 50 Nm | 545 or 800 Wh | Shimano Nexus 8-speed, chain | 26.60 kg (L) |
| District+ 4 | Bosch Performance Line, 75 Nm | 545 or 800 Wh | Nexus 5-speed, Gates CDX belt | 26.20 kg (L) |
| District+ 4 Lowstep | Bosch Performance Line, 75 Nm | 545 or 800 Wh | Nexus 5-speed, Gates CDX belt | 25.60 kg (M) |
| District+ 5 | Bosch Performance Line, 75 Nm | 545 or 800 Wh | Enviolo Trekking, Gates CDX belt | 27.10 kg (L) |
Our take: this District+ 4 800 Wh has the same Trek published weight as the 545 Wh version (26.20 kg in L), with 255 Wh of extra reserve. If your journeys are short, the 545 Wh is enough; if you want Enviolo continuously variable gearing, the District+ 5 comes in at 27.10 kg in L.

LVR sizing advice This colour is offered in XL (186 to 197 cm) and XXL (196 to 203 cm). The straight top tube means stepping over it: if you often get on the bike carrying a bag or wearing a skirt, also look at the Lowstep version. 175 mm cranks and a 105 mm stem on both sizes.
