Trek FX+ 1S

What the Trek FX+ 1S is built for

The Trek FX+ 1S is a commuter e-bike, built for daily rides to work, errands and city streets.

It has a 500 W motor and 60 Nm of torque.

It carries a 520 Wh battery and a stated range of up to 50 miles (80 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.

In the United States the Trek FX+ 1S sells for $2,000, above the median of $1,700 across 311 commuter e-bikes with a US price, among the premium models. That is $4 per watt-hour of battery.

Where the Trek FX+ 1S 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 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.

Trek FX+ 1S safety certification

The brand's listing for the Trek FX+ 1S does not state a UL 2849 or EN 15194 certification. New York City allows only e-bikes certified to UL 2849 to be sold or rented there, and California requires certified batteries from 2026; ask the seller for the certificate before buying.
