For leisure rides as a couple or with the family, along the Canal du Midi or on country lanes, without worrying about gears. It's particularly suited to anyone new to e-bikes who's wary of the complexity of a derailleur.
Belt and internal gear hub: clean mechanics. This Charter+ 4 Lowstep replaces the chain and derailleur with a Gates CDX belt and a Shimano Nexus 5-speed hub. The gears work protected inside the hub shell, and the belt needs neither oil nor grease. The bolt-on adjustable rear dropout on the Alpha Platinum frame is used here to set the belt tension.
| 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 Nexus 5 540 Wh Lowstep puts peace of mind ahead of gear range. At 30.60 kg in size M according to Trek, it even weighs slightly less than the derailleur-equipped R9 version.
Five well-spaced gears are easy to understand: one for pulling away, one or two for cruising, the others for fast riding on the flat. You don't need to plan ahead before stopping, since the hub changes gear even when the wheel isn't turning. The Bosch motor, active up to 25 km/h, does the rest.
The 2.40-inch E6 Hard-Case Lite tyres, with their reflective sidewalls, roll well on tarmac and handle towpaths. The wide, padded Bontrager Boulevard saddle and the suspension seatpost give you a comfortable perch for rides in everyday clothes.
| 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 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 R9 540 Wh Lowstep | Bosch Performance Line 75 Nm / 540 Wh | Shimano CUES 9-speed | 63 mm coil | 30.80 kg (M) |
Our take: this green Nexus 5 540 Wh shares everything with the blue and black versions. Compared with the Enviolo 540 Wh Lowstep (31.60 kg in M), it's 1 kg lighter, with 5 fixed gears instead of continuously variable gearing.

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.
