NBD S5i
The clean, quiet NBD — Gates belt drive, Shimano Nexus 5-speed hub, Magura brakes, and a stronger motor. Same ultra-low step, zero maintenance drivetrain.
The NBD S5i takes everything that makes the P8i so accessible and adds the polish of a premium drivetrain. Gates Carbon Drive CDX belt replaces the chain — no grease, no lube, no noise. The Shimano Nexus INTER-5E e-bike specific hub gives you 5 smooth gears that shift at any speed, even at a standstill. Magura MT4 hydraulic brakes replace Shimano's for more powerful stopping. And the Bosch Performance Line motor steps up to 65 Nm and 300% assist, paired with a larger 500 Wh battery for up to 118 km of range. Same 39 cm step-over, same folding frame, significantly more bike.
Highlights
39 cm ultra-low standover — same as P8i
The S5i shares the NBD's defining feature — a 39 cm (15.4") step-over height that makes getting on and off effortless for all riders, regardless of height, age, or mobility. No high top tube to navigate.
Gates Carbon Drive CDX belt — zero maintenance
No chain, no grease, no lube — ever. The Gates CDX belt is silent, clean, rust-proof, and built to outlast any chain. Paired with the Nexus INTER-5E hub, it's the cleanest, most carefree drivetrain on the NBD lineup.
Shimano Nexus INTER-5E — e-bike specific 5-speed IGH
The INTER-5E is Shimano's internally geared hub built specifically for e-bikes — handles the higher torque loads with ease. 5 evenly spaced gears shift at any speed or cadence, including at a complete standstill. No derailleur to adjust, ever.
Bosch Performance Line — 65 Nm, 300% assist
A meaningful step up from the Active Line Plus on the P8i — 65 Nm of torque and 300% assist make hills and loaded starts noticeably easier, while still feeling smooth and natural rather than aggressive.
Magura MT4 hydraulic disc brakes
Upgraded from Shimano hydraulics on the P8i to Magura MT4 — more braking power and feel for confident stops at any speed, with or without a passenger on the rack.
500 Wh battery — 51–118 km range
25% more battery capacity than the P8i (500 Wh vs 400 Wh) for significantly longer range — handles longer commutes and errand runs without anxiety about charge.
RideEasy suspension seatpost — air cartridge, preload adjustable
An upgraded version of the RideEasy seatpost from the P8i — includes an air cartridge and preload adjustment so you can dial in the suspension feel to your weight and preference.
Gaia Rack — 27 kg, child seat compatible
Rated to 27 kg (60 lb) and compatible with many child seats. Supports vertical parking when folded — store the bike upright in tight spaces.
Folds in 5 seconds · fits 147–190 cm
Folds to 38×156×79 cm in ~5 seconds. Physis 3D handlepost and Andros adjustable stem fit riders from 4'10" to 6'3" without tools.
