The LVR workshop view

District+ 3 Lowstep Belt: Alpha Platinum and belt drive together. This version gets a different frame: Trek uses its Alpha Platinum aluminium here, a higher grade than Alpha Smooth, with a battery that slides out through the top of the down tube and cables integrated right from the cockpit. The drivetrain pairs the Nexus 8-speed hub with a Gates CDC CenterTrack belt that needs neither oil nor degreaser.

	Nexus 7-speed + chain	Nexus 8-speed + chain	Nexus + Gates belt
How it works	Gears enclosed in the rear hub	Same principle, one more gear	Carbon belt instead of a chain
Maintenance	Chain needs lubing, sealed hub	Chain needs lubing, sealed hub	No grease or rust, just a tension check
Reference bike	District+ 1 and 2	District+ 3	District+ 2 Belt and 3 Lowstep Belt
What it means	Simplicity, change gear when stationary	Wider range for the hills	Clean trousers, very long life

In short: at 25.20 kg in size M according to Trek, this District+ 3 Lowstep Belt weighs 1 kg less than the chain-driven District+ 3 Lowstep. It's the most refined of the District+ models with the Active Line Plus motor.

Integrating the cables right from the cockpit gives a clean front end, with no dangling housings. The battery loads through the top of the down tube: you remove it standing up, with no fiddly handling. This Alpha Platinum frame is also the lightest in the District+ 3 series.

With 545 Wh, the battery comfortably covers a week of urban journeys. The 50 Nm Active Line Plus motor provides natural assistance up to 25 km/h, as the law requires. The Gates belt means no greasy chain and no stained trousers, and the adjustable stem fine-tunes the riding position.

Which District+ should you choose?

Model	Motor	Battery	Drivetrain	Weight (size)
District+ 2 Belt Lowstep	Bosch Active Line Plus 50 Nm	400 Wh	Nexus 7-speed, belt	26.10 kg (M)
District+ 3 Lowstep	Bosch Active Line Plus 50 Nm	545 or 800 Wh	Nexus 8-speed, chain	26.20 kg (M)
District+ 3 Lowstep Belt	Bosch Active Line Plus 50 Nm	545 or 800 Wh	Nexus 8-speed, belt	25.20 kg (M)
District+ 4 Lowstep	Bosch Performance Line 75 Nm	545 or 800 Wh	Nexus 5-speed, belt	25.60 kg (M)

Our take: this dark grey only comes in M and L, whereas the Dark Aquatic blue also offers S. With 545 Wh, it's for everyday use; the 800 Wh is aimed at long distances.
