Is a 1200W motor legal on a city e-bike?

In the US, a 1200W motor exceeds the 750W limit for Class 1–3 e-bikes, so check your state and local rules before riding on bike paths or roads. Many European markets cap motors at 250W continuous.

How far can it go on a charge?

The listing gives no range figure. A 1200W motor at 48V draws heavily, so expect shorter range than a 250–500W commuter bike with a similar battery. Ask the seller for the battery's watt-hours to estimate.

How does it compare with a 20-inch folding e-bike?

It has the same compact wheel size but a classic city frame, so it is likely easier to mount but does not fold. Folding rivals are better for apartments and car trunks; this one is better for upright city riding.

What size rider does a 20-inch e-bike fit?

Small wheels suit shorter riders and tighter storage, but the frame geometry decides fit. The listing gives no frame size or rider height range, so confirm both with the seller before buying.

What comes in the box?

The listing does not say. Expect the bike, battery and charger at minimum, but confirm whether a charger, tools or a manual are included before ordering.
