For the commuter who rides a long way every day, often into the wind, and wants a drivetrain perfectly matched to every change in effort. It will suit anyone riding the coast road, exposed to gusts.
Continuously variable gearing and touring range. This Charter+ 4 brings together the Enviolo City hub, the Gates CenterTrack belt and the 800 Wh PowerTube in the step-through Alpha Platinum aluminium frame. The ratio adjusts without steps, the belt never needs greasing, and the big battery needs charging less often. It's the most refined Charter+ 4 in terms of drivetrain comfort.

| 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 top of the Charter+ 4 range, weighed by Trek at 32.50 kg in size M. It's designed for riders who string together long journeys and want a quiet, clean bike with no derailleur adjustment.
Riding into the tramontane or a sea breeze, the effort changes with every gust. With the Enviolo, you lengthen or shorten the ratio in one movement, without waiting for a specific click: your cadence stays constant, and the Bosch motor, active up to 25 km/h, adds to your effort.
The 800 Wh Bosch smart system battery saves you charging every evening on a long daily commute. The aluminium mudguards and the tyres with reflective sidewalls complete a kit built for riding all year round.
| Model | Motor / battery | Drivetrain | Fork | Weight (size) |
| Charter+ 4 Nexus 5 belt 800 Wh Lowstep | Bosch Performance Line 75 Nm / 800 Wh | Nexus 5 + belt | 63 mm coil | 31.50 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 800 Wh Lowstep | Bosch Performance Line PX 90 Nm / 800 Wh | Automatic Enviolo + belt | Mobie 34 air 80 mm | 31.50 kg (M) |
Our take: identical to the grey colour, this red is purely a matter of taste. The Charter+ 5 Auto 800 Wh (31.50 kg in M) selects the ratio automatically and moves up to the 90 Nm 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.

| Is the Enviolo suited to windy conditions? | Yes, continuously variable gearing lets you keep a steady cadence despite the gusts. |
| Do I need to charge every evening? | Not necessarily with the 800 Wh; it depends on your journey and the mode. |
| Does the hub need servicing? | A periodic check in the workshop; nothing day to day. |
| Is the red vivid? | Yes, Fury Red is a bold, vibrant red. |

The LVR Cycles verdict A long-range, smooth Charter+ for long exposed journeys, where every gust means adjusting your effort. Its vibrant red makes it visible from afar.
