For the rider who's demanding about comfort, with a sensitive back or wrists, who rides a lot and wants a bike set up precisely for them. It will also suit a couple of different builds sharing the same model.
The top-of-the-range derailleur Charter+. The Charter+ 5 R10 keeps the step-through Alpha Platinum aluminium frame, but moves up a notch on every component: a 90 Nm Bosch Performance Line PX motor, a Kiox 500 display, an SR Suntour Mobie 34 air-sprung fork, Shimano MT420 brakes on 180 and 203 mm rotors and a seatpost with adjustable springs. The 800 Wh battery completes the package.
| Charter+ 5 (Performance Line PX) | Charter+ 4 (Performance Line) | Charter+ 5 Auto (PX + Enviolo) | |
| Motor | 90 Nm, Kiox 500 display | 75 Nm, Purion 200 control | 90 Nm, Kiox 500 display |
| Drivetrain | CUES 10-speed 11-48 | CUES 9-speed, Nexus 5 or Enviolo | Automatic Enviolo + belt |
| Reference bike | R10 540 Wh Lowstep, 30.30 kg (M) | R9 540 Wh Lowstep, 30.80 kg (M) | Auto 540 Wh Lowstep, 30.60 kg (M) |
| What it means | Easier on hills and with loads | Gentle assistance, simplicity | No more gears to choose |
In short: this is the most complete derailleur-equipped Charter+, with the highest torque in the range and the big battery. Trek quotes 31.20 kg in size M, which is 0.50 kg less than the Charter+ 4 R9 800 Wh.
An air-sprung fork is inflated with a high-pressure pump: you adapt its firmness to the rider's weight, something a coil-sprung fork only partly allows. The Mobie 34 adds rebound and compression adjustment, plus a lockout for long straight stretches.
The sprung seatpost firms up or softens according to your weight; its length goes from 300 mm in S and M to 350 mm in L and XL. Combined with the fork, it smooths out road joints and kerbs, and you arrive less tired after a long ride.
| Model | Motor / battery | Drivetrain | Fork | Weight (size) |
| Charter+ 5 R10 540 Wh Lowstep | Bosch Performance Line PX 90 Nm / 540 Wh | Shimano CUES 10-speed | Mobie 34 air 80 mm | 30.30 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 R9 800 Wh Lowstep | Bosch Performance Line 75 Nm / 800 Wh | Shimano CUES 9-speed | 63 mm coil | 31.70 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: the R10 800 Wh is 0.90 kg heavier than the R10 540 Wh (30.30 kg in M), for 260 Wh more. Compared with the R9 800 Wh (31.70 kg), it adds the air fork, the adjustable seatpost and 15 Nm of torque.

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.
