Riders mix these two up constantly. An e-bike (PAB) and an e-scooter (PMD) look similar on paper: both electric, both capped at the same top speed, both need LTA paperwork before you ride. But they follow different rules, and picking the wrong one for your commute is the fastest way to get fined.
What is a PAB (e-bike)?
A PAB is a power-assisted bicycle. It has pedals, a saddle, and a motor that helps only while you pedal, with no throttle. The motor cuts off once you hit the shared-path speed cap of 25 km/h. Our X16 and X20 are built to this spec.
A PAB rides on public roads (the cyclist part of the road), park connectors (PCN) and shared paths. It cannot go on footpaths. This is the one real advantage over a PMD: a PAB rider can take the road when the cycling network doesn’t reach where they’re going.
To be street-legal, a PAB must be registered with LTA, stay under 70 cm wide, and be certified to the EN15194 standard, not UL2272. That’s a PMD certification, and it’s a common mix-up even among sellers. Buy an LTA-approved e-bike and the certification, registration and inspection cycle is already sorted for you.
What is a PMD (e-scooter)?
A PMD is a motorised personal mobility device. No pedals, you control it by throttle. Our F-07X and F-09S fall in this category. Like a PAB, it’s capped at 25 km/h.
A PMD rides on cyclist paths, PCNs and shared paths, but never on public roads. It also must be registered with LTA and kept under 70 cm wide. The certification requirement here is UL2272, the fire-safety standard covering the battery and charging system. Only UL2272-certified devices can be registered with LTA in the first place, so an uncertified e-scooter is a dead end twice over: it can’t be registered, and riding it unregistered on a public path is an offence. Registration isn’t a one-time thing either. LTA requires a PMD to go back for re-inspection every two years.
PAB vs PMD, side by side
Both devices share the same width limit (under 70 cm), the same speed cap (25 km/h) and the same registration requirement. What actually splits them: a PAB can take the road, a PMD cannot. A PAB is certified to EN15194 and a PMD to UL2272, and the two aren’t interchangeable. A device approved under one standard isn’t automatically legal under the other. A PAB has pedals and rides like an assisted bicycle, while a PMD is throttle-only, closer to a motorcycle.
If your commute mixes road stretches with cycling paths, a PAB gives you more route flexibility. If you’re sticking to cycling paths, shared paths and PCNs the whole way, a PMD covers the same ground without the pedalling.
Why the certification split matters
Sellers who don’t stock LTA-approved devices often blur this line, especially once a “faster” model shows up that clearly isn’t built to either standard. A device that hits well above the legal speed cap isn’t a quicker version of a legal PAB or PMD. It’s a different, unregistrable device. Riding one, or riding either category unregistered, carries a real fine and the risk of jail time under the Active Mobility Act. It’s not worth the shortcut.
More on why the standard matters in our guide to UL2272 certification.
Getting registered
For both devices, registration with LTA happens before you’re allowed on public paths. Riders need to pass LTA’s online theory test and be at least 16 years old. Buying from an LTA-approved retailer means the paperwork and certification are already handled. An unregistered or modified grey-market import generally cannot be registered at all, no matter how good it looks.

What happens when a device doesn’t meet the spec
This isn’t hypothetical. In one widely reported case, LTA officers stopped a rider on Bedok North Road and impounded her e-scooter on the spot. Its top speed was 29 km/h, well over the 25 km/h limit. The e-scooter was loaded onto the lorry there and then, and a bill for towing and storage fees landed on her afterwards.
Which one should you get?
Match the device to the route you actually ride, not the other way round. Commuting from an HDB estate to an MRT station along park connectors, either works. Need to cover a stretch of road to get there, and the PAB is the only legal option of the two.
