Who is it for?

For the urban rider who wants a bike with no chain maintenance, lighter than the other District+ 3 models, and who rides in everyday clothes. It suits riders from 155 to 186 cm according to Trek, for daily commuting and rides along the canal.

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.

The Alpha Platinum frame uses one of Trek's most advanced aluminium alloys. Here it saves 1 kg compared with the chain-driven District+ 3 Lowstep. The battery comes out through the top of the down tube, a simple job, with no need to turn the bike over or bend down under the frame.

The Gates CDC belt needs no grease, doesn't rust and won't dirty your clothes. Paired with the Nexus 8-speed hub, it gives a quiet and very durable drivetrain. The Active Line Plus motor assists up to 25 km/h, the European limit, and is very quiet.

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: at 25.20 kg in M, this Belt is the lightest of the District+ 3 Lowstep models. With 545 Wh, it's aimed at town riding; the 800 Wh version in the same colour suits long rides. The District+ 4 Lowstep moves up to the 75 Nm motor.
