For anyone who wants an e-bike that's easy to step through, with no gears to manage, but with enough battery for long rides on the flat. It will suit seniors and smaller riders alike, from size S, intended for 147 to 155 cm.
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.
The principle is simple: you step on through the front of the low frame, choose an assistance mode and pedal. No derailleur, no chain, no adjustment: the Gates belt transmits your effort silently. The Bosch hub motor supports each pedal stroke progressively, up to 25 km/h.
With 540 Wh, the battery offers a good reserve for rides of several hours. To look after it, ideally charge it before it's completely empty, and store it indoors in winter. The Shimano hydraulic brakes need no effort to operate, a real comfort for your hands.
| 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 B 540 LS adds 180 Wh to the B LS for 900 g (21.40 kg versus 20.50 kg in M). If your route climbs, the R10 LS (22.40 kg) adds ten gears and another 60 Wh.
