What do the labels mean?

UL safety standards

UL 2271: the battery pack.
UL 2849: the e-bike’s electrical system, including its battery and charger combination.

Ask for certification for the exact model.

Other labels

UN 38.3: transport tests.
IP: dust and water protection.

These do not replace e-bike electrical safety certification.

Volts, Ah and Wh

V: voltage.
Ah: charge capacity.
Wh: stored energy.

These describe performance, not safety certification.

KNOW THE RULES WHERE YOU RIDE

E-bike regulations.

Choose your country and province or state. Open the official source for the full rules.

CountryProvince or territory

Turn on JavaScript to use the location selector. You can read British Columbia’s official e-bike rules here.

Check the road or trail too.

Province and state rules are the starting point. Cities, parks and land managers may set additional rules for paths, sidewalks and trails. Check the local authority and posted signs before riding.

A Class 1, 2 or 3 sticker does not establish that a bike is legal in every location. Battery safety certification is also a separate question from permission to ride.

Understand Classes 1, 2 and 3
