Who is it for?

For the city dweller who wants an elegant, discreet e-bike that's easy to step through, for everyday trips around Béziers and its flat surroundings. It's for anyone who wants to charge less often than with a 360 Wh battery, without giving up the belt.

The LVR workshop view

The belt-drive Lowstep that goes further. This model combines three simple ideas: a Lowstep frame you step through effortlessly, a Gates Sidetrack belt that does away with chain and grease, and a 540 Wh PowerTube battery, 50 % more than on the Inbound+ 2 B LS. The Bosch motor, hidden in the rear hub, leaves the chainset area uncluttered. Alpha Smooth aluminium frame.

	PowerTube 540 Wh (B 540 LS)	PowerTube 360 Wh (B LS)	PowerTube 600 Wh (R10 LS)
Capacity	540 Wh	360 Wh	600 Wh
Paired drivetrain	Belt, 1-speed	Belt, 1-speed	CUES, 10-speed
Lowstep version	21.40 kg (M)	20.50 kg (M)	22.40 kg (M)
What it means	Maintenance-free, less frequent charging	Light, short journeys	For hills and touring

In short: at 21.40 kg in M, the Inbound+ 2 B 540 LS adds 180 Wh to the belt-drive Lowstep for 900 g more. It stays lighter than the R10 LS, but keeps a single speed: it's made for flat or gently rolling routes.

In town, simplicity is a virtue: no gears to change at the lights, no chain coming off, no grease. The Gates belt and the Bosch hub motor offer a smooth, quiet ride, with assistance cutting out at 25 km/h. The low frame makes frequent stops easy.

The 540 Wh PowerTube battery locks into the frame with a key and comes out for charging at home. The Shimano hydraulic brakes on 180 mm rotors provide powerful, progressive braking in traffic. Get a D-lock and insurance, both essential for an urban e-bike.

Which Inbound+ should you choose?

Model	Motor / battery	Drivetrain	Frame	Weight (size)
Inbound+ 2 B LS	Bosch hub 45 Nm / 360 Wh	Gates belt, 1-speed	Lowstep	20.50 kg (M)
Inbound+ 2 B 540 LS	Bosch hub 45 Nm / 540 Wh	Gates belt, 1-speed	Lowstep	21.40 kg (M)
Inbound+ 2 R10 LS	Bosch hub 45 Nm / 600 Wh	Shimano CUES 10-speed	Lowstep	22.40 kg (M)
Inbound+ 2 B 540	Bosch hub 45 Nm / 540 Wh	Gates belt, 1-speed	Straight	21.60 kg (L)

Our take: this black B 540 LS weighs 900 g more than the B LS (20.50 kg in M) for 180 Wh more. Compared with the R10 LS (22.40 kg), it saves 1 kg but gives up the ten gears.
