Who is it for?

The LVR workshop view

540 Wh: the reserve that changes your habits. A Bosch battery is measured in watt-hours, the amount of energy stored. Going from 360 to 540 Wh gives you one and a half times more energy with the same Active Line Plus motor, so you can ride longer between charges or stay in a higher assistance mode. On this frame, the PowerTube sits inside the down tube and comes out for charging at home.

	PowerTube 360 Wh	PowerTube 540 Wh	PowerTube 600
Version	District+ 3 N7 360 / R9 360	District+ 3 N7 540 / N7 B / R9 540	District+ 4 N5 B / R10
Paired motor	Active Line Plus	Active Line Plus	Performance Line 75 Nm
Charging	The quickest to top up	Longer charge, less often	Large capacity, hungrier motor
Who for	Short daily journeys	Long journeys, day rides	Hills, loads, demanding journeys

In short: the same bike as the N7 360, the same Nexus 7-speed hub, but with a 540 Wh battery. It's the logical choice if your journey goes beyond the town centre or if you don't want to charge every evening.

On the canal towpath, with its sometimes uneven surface, the 50 mm Bontrager E6 tyres, the 60 mm fork and the suspension seatpost work together to smooth out roots and loose gravel. The Active Line Plus motor delivers steady, quiet assistance, pleasant on those long, shaded straights.

With 540 Wh, a full day out becomes possible while staying in a reasonable assistance mode, especially if the sea breeze picks up on the way back. Charge the battery the day before and take the charger for a very long loop; we help you plan your route based on your habits.

Which District+ should you choose?

Model	Motor	Battery	Drivetrain	Weight (L)
District+ 3 N7 360 LS	Bosch Active Line Plus	360 Wh	Nexus 7-speed hub, chain	26.80 kg
District+ 3 N7 540 LS	Bosch Active Line Plus	540 Wh	Nexus 7-speed hub, chain	27.70 kg
District+ 3 N7 B LS	Bosch Active Line Plus	540 Wh	Nexus 7-speed hub, Gates belt	27.20 kg
District+ 3 R9 540 LS	Bosch Active Line Plus	540 Wh	CUES 9-speed derailleur	24.30 kg

Our take: for leisure rides, this N7 540 keeps the robust Nexus drivetrain and adds 180 Wh to the N7 360. If your rides include steep hills, the R9 540 offers a wider gear range with its 11-46 derailleur setup.

LVR sizing advice

Thanks to the low step-over, the top tube height hardly matters: go by your height. S for 147 to 155 cm, M for 155 to 173 cm, L for 170 to 185 cm, XL for 185 to 203 cm. If you're on the M / L borderline, try both in the shop: the 110 mm stem on the L stretches the position noticeably.

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
Stem (mm)	70	70	110	110

Your questions

Can I ride on the towpath?	Yes, the 50 mm tyres and suspension fork suit hard-packed tracks.
Which mode saves the battery?	The lowest mode on the flat, then a higher mode into the wind or on climbs.
Can panniers be fitted?	Yes, on the MIK-compatible rear rack.
Is the red vivid?	It's a dark, deep red, more elegant than flashy.
