For riders who dream of heading off for several days with panniers, stage by stage, on the greenways and back roads of the Languedoc. It's also for anyone who wants a weekend bike able to carry what they need for a night away.
The maximum energy reserve of the derailleur-equipped Charter+ 4. Here Trek slips an 800 Wh Bosch PowerTube into the Alpha Platinum aluminium down tube, without changing the silhouette of the step-through frame. The battery's mass stays low and central, between the two wheels, which steadies the bike when stationary and in slow corners. The rack and mudguards are part of the frame itself.
| 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: compared with the 540 Wh version, you gain 260 Wh of capacity for 0.90 kg more according to Trek (31.70 kg versus 30.80 kg in M). The rest of the bike is identical: same motor, same drivetrain, same equipment.
The Passa Païs greenway, which heads towards the Hauts Cantons along a former railway line, is ideal terrain for a first tour: gentle gradients, little traffic and long distances. The 800 Wh battery is well suited to these days out; remember to pack the charger for the evening stop.
When loaded, a trekking bike must brake with confidence: the MT200 hydraulic brakes on 180 mm rotors modulate deceleration well. The step-through frame makes getting on easy even with bulky rear panniers, with no need to swing your leg over the luggage.
| Model | Motor / battery | Drivetrain | Fork | Weight (size) |
| Charter+ 4 R9 540 Wh Lowstep | Bosch Performance Line 75 Nm / 540 Wh | Shimano CUES 9-speed | 63 mm coil | 30.80 kg (M) |
| Charter+ 4 R9 800 Wh Lowstep | Bosch Performance Line 75 Nm / 800 Wh | Shimano CUES 9-speed | 63 mm coil | 31.70 kg (M) |
| Charter+ 5 R10 800 Wh Lowstep | Bosch Performance Line PX 90 Nm / 800 Wh | Shimano CUES 10-speed | Mobie 34 air 80 mm | 31.20 kg (M) |
| 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) |
Our take: with 260 Wh more than the R9 540 Wh for an extra 0.90 kg, this 800 Wh is the logical choice for touring. If you want torque for loaded climbs, the Charter+ 5 R10 800 Wh offers 90 Nm and an air fork.

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.
