Who is it for?

For the urban rider who stops at every junction and wants to pull away smoothly, without ever being in the wrong gear. It will suit anyone who finds conventional gears confusing or tiring.

The LVR workshop view

Enviolo: the right ratio, with no steps. This Charter+ 4 Lowstep hands its drivetrain over to an Enviolo City continuously variable hub, driven by a Gates CDX CenterTrack belt. There are no gears in the conventional sense any more: you vary the ratio smoothly, like a slider. The low step-over Alpha Platinum frame keeps its integrated mudguards and rack.

	Shimano CUES derailleur	Nexus 5 hub + belt	Enviolo hub + belt
How it works	9 sprockets and a Linkglide chain	5 gears enclosed in the hub	Continuously variable, no steps
Maintenance	Chain needs cleaning and lubing	Grease-free belt, sealed hub	Grease-free belt, sealed hub
Reference bike	Charter+ 4 R9, 30.80 kg (M, 540 Wh)	Charter+ 4 Nexus 5, 30.60 kg (M, 540 Wh)	Charter+ 4 Enviolo, 31.60 kg (M, 540 Wh)
What it means	Widest gear range	Shifts at a standstill, clean	The ideal gear at any moment

In short: the Charter+ 4 Enviolo 540 Wh Lowstep is for those who want a smooth ride, with no jolts and no chain maintenance. Trek quotes 31.60 kg in size M, 1 kg more than the Nexus 5 version.

With an Enviolo hub, there are no numbered gears: you twist the shifter and the ratio changes progressively, with no clicks or jumps. As you approach a set of lights on the Allées Paul Riquet, you select a low ratio, even at a standstill, and pull away without a jolt.

The Gates CDX CenterTrack belt, guided by a central groove, can't derail and needs no grease. The 2.40-inch E6 Hard-Case Lite tyres and the 63 mm coil fork soak up the cobbles and road joints of the town centre.

Which Charter+ should you choose?

Model	Motor / battery	Drivetrain	Fork	Weight (size)
Charter+ 4 Nexus 5 belt 540 Wh Lowstep	Bosch Performance Line 75 Nm / 540 Wh	Nexus 5 + belt	63 mm coil	30.60 kg (M)
Charter+ 4 Enviolo belt 540 Wh Lowstep	Bosch Performance Line 75 Nm / 540 Wh	Enviolo City + belt	63 mm coil	31.60 kg (M)
Charter+ 4 Enviolo belt 800 Wh Lowstep	Bosch Performance Line 75 Nm / 800 Wh	Enviolo City + belt	63 mm coil	32.50 kg (M)
Charter+ 5 Auto 540 Wh Lowstep	Bosch Performance Line PX 90 Nm / 540 Wh	Automatic Enviolo + belt	Mobie 34 air 80 mm	30.60 kg (M)

Our take: 31.60 kg in M, which is 1 kg more than the Nexus 5 540 Wh Lowstep, for a stepless drivetrain. The Charter+ 5 Auto 540 Wh (30.60 kg) makes the choice of ratio automatic and moves up to the PX motor.

LVR sizing advice

You get onto the Lowstep frame from the front, without lifting your leg: the size is chosen mainly on saddle height and reach. Trek's ranges overlap between M and L (170 to 173 cm); in that case, the smaller size gives a more upright position and the larger one more room for long rides. The height-adjustable stem then fine-tunes the position.

Size	S	M	L	XL
Rider height (cm)	147-155	155-173	170-185	185-203
Inseam (cm)	69-88	77-96	80-99	86-105
Wheels (in)	27.5	27.5	27.5	27.5
Seatpost (mm)	300	300	300	300

Your questions

How does continuously variable gearing work?	You twist the shifter and the ratio changes progressively, with no steps.
Can I change ratio at a standstill?	Yes, it's very handy before pulling away at the lights.
Can the belt come off?	The CenterTrack belt is guided by a central groove that keeps it in place.
Is the grey light?	Lunar Silver is a light silver grey with a bright finish.

The LVR Cycles verdict

An exceptionally smooth city Charter+ that does away with the very idea of changing gear. Its bright silver grey gives it a modern look.
