Hiboy EX6F

What the Hiboy EX6F is built for

The Hiboy EX6F is a folding e-bike that packs down to fit a car boot, an apartment or a train.

It has a 500 W (750 W peak) hub motor and a top speed of 25 mph (40 km/h).

It carries a 696 Wh removable battery and a stated range of up to 75 miles (121 km) on a charge. Real-world range is usually lower than the rated figure: it falls with throttle use, hills, cold weather, rider weight and higher assist levels.

The Hiboy EX6F carries up to 265 lb (120 kg) including the rider, has front suspension and is rated IPX4 against water.

In the United States the Hiboy EX6F sells for $950, above the median of $800 across 24 folding e-bikes with a US price, among the premium models. That is $1 per watt-hour of battery.

Where the Hiboy EX6F may be ridden

In the European Union and the United Kingdom an e-bike counts as a bicycle only within the pedelec limits; as specified, its 500 W motor is above the 250 W limit, its 25 mph (40 km/h) top speed is above the 25 km/h at which assistance must stop and its throttle moves it without pedalling, which the pedelec rules allow only as start-up help at walking pace. A model above those limits is treated as a moped there, with type approval, registration and insurance, unless the brand sells a version set to the European limits.

Hiboy EX6F safety certification

The brand states that the Hiboy EX6F is certified to UL 2849.

UL 2849 is the US safety standard for the whole electrical system of an e-bike: battery, charger, motor and controller tested together.

New York City allows only e-bikes certified to UL 2849, with batteries certified to UL 2271, to be sold or rented there; California requires e-bike batteries to meet UL 2849 or EN 15194 from 2026.
