Who is it for?

For the rider used to a coaster brake, often since childhood or a stay in the Netherlands, and for smaller riders: the XS suits riders from 147 cm. It is also aimed at anyone who wants an urban electric bike that never needs lubing.

The LVR workshop view

Coaster brake and belt: the most "Dutch" District+ 4. This model combines two habits dear to cyclists in the Netherlands, where Trek designs its urban e-bikes: you brake by pedalling backwards, thanks to the brake housed in the Nexus hub, and the chain gives way to a Gates CDX belt. The two Shimano hydraulic disc brakes are still on the handlebar: the coaster brake is an addition, it doesn't replace anything.

	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 Coaster Belt Lowstep is aimed at those who grew up with a coaster brake or who want a bike that never needs lubing, with a step-through frame available from size XS.

The coaster brake works as soon as you push the pedal backwards. It is housed in the hub, sheltered from the rain. One quirk to be aware of: you can't backpedal to position the pedal before setting off; you have to place it by turning it forwards. You get used to it in a few minutes.

The Gates CDX belt replaces the chain: it doesn't rust, doesn't dirty your clothes and runs almost silently. Combined with the Nexus hub, which hides its five gears inside, it gives a virtually maintenance-free drivetrain. The Bosch motor's assistance, in line with the law, stops at 25 km/h.

Which District+ should you choose?

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: compared with the District+ 4 Lowstep (25.60 kg in M), this Coaster Belt version weighs 400 g more to add the coaster brake and size XS. The 800 Wh version brings 255 Wh more at the same Trek weight.

LVR sizing advice

Four sizes from XS to L cover riders from 147 to 186 cm. With a coaster brake, a position where your foot easily reaches the ground when stopped is reassuring: if in doubt, the smaller of the two sizes is often the right one. The L moves to 175 mm cranks and a 105 mm stem.

Size	XS	S	M	L
Rider height (cm)	147-155	155-165	165-175	175-186
Inseam (cm)	69-73	72-78	77-83	82-88
Cranks (mm)	170	170	170	175
Stem (mm)	85	85	85	105

Your questions

Does the coaster brake replace the hand brakes?	No, it is in addition to the two Shimano MT200 hydraulic disc brakes.
Can I backpedal?	No, a backward movement applies the brake; that is how a coaster brake works.
What is the minimum rider height?	The XS suits riders from 147 cm according to Trek.
Is the belt easy to replace?	Replacement is rare and done in the workshop; we take care of it.
