Who is it for?

For the leisure rider who loves long day rides, a picnic in the panniers and the ride home without watching the battery gauge. It also suits active retirees who ride several times a week without wanting to recharge after every outing.

The LVR workshop view

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 Canal du Midi towpath, heading west from the Fonseranes locks, is flat but sometimes rough: the 63 mm coil fork, the suspension seatpost and the 2.40-inch tyres keep you comfortable after hours in the saddle. The assistance, limited to 25 km/h, is especially helpful for getting going again into a headwind.

The 800 Wh battery with the Bosch smart system slides in through the top of the down tube. It adds 0.90 kg compared with the 540 Wh, weight carried low that you barely notice when riding. To make it last, store it somewhere dry at a moderate temperature between rides.

Which Charter+ should you choose?

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: 31.70 kg in M for 800 Wh, versus 30.80 kg for the 540 Wh version: the extra weight is small given the capacity gained. If you want more torque, the Charter+ 5 R10 800 Wh goes up to 90 Nm and weighs 31.20 kg.

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
