Finding Class 2 Sticker Locations for CA E-Bikes

The Class 2 sticker on a California e‑bike is most often located on the frame near the bottom bracket, on the downtube, or on the seat tube. California law (AB 1096) requires this sticker to be permanently affixed and clearly visible. If you are searching for yours, start with those three spots, then check the battery mount area or near the motor. Below are specific locations by bike type and brand, plus what to do if the sticker is missing.

Where to Check First – Frame and Battery Area

Most e‑bike manufacturers place the Class 2 label where it is easy to see during a quick inspection but not so exposed that it peels off. Still, there is no universal spot: the location changes by brand, model, and even the year of production. For example, early‑model Rad Power Bikes placed the sticker on the downtube, but later versions of the same model moved it to the battery tray. That means your best strategy is to check all three common frame zones before moving to the battery area.

The most common locations are:

• Bottom bracket – the underside of the frame where the pedals attach. This is a frequent spot on mid‑drive bikes like the Specialized Turbo Vado and Trek Allant+.
• Downtube – the main top tube running from the headset to the bottom bracket. Rad Power Bikes and Aventon often put the sticker here, close to the battery connector.
• Seat tube – just below the saddle, above the battery on step‑through frames. Juiced Bikes sometimes uses this area on their CrossCurrent models.
• Battery mount – on bikes with a removable downtube battery, check the frame panel near the battery release lever. The Lectric XP 3.0 has the sticker on the battery tray itself.

If your bike has a rear rack battery, the sticker may be on the rack’s support arm or the rear of the main frame near the dropouts.

What to Do Once You Find the Sticker

When you locate the sticker, read the printed specs. Confirm the motor wattage and maximum assisted speed match what your bike actually does. For a Class 2 bike, the throttle should cut off at 20 mph on level ground. Use a GPS bike computer or a phone app to verify that top speed. If the bike exceeds 20 mph under throttle power while the sticker says Class 2, the bike may have been modified or mislabeled – a problem that requires a call to the manufacturer.

If you still cannot locate the sticker after checking all common spots, refer to your bike’s owner’s manual. It often includes a diagram of where the label is placed for that specific model. For used e‑bikes, ask the previous seller for the original paperwork. The sticker location is usually consistent across production runs of the same model.

Sticker Variations by E‑Bike Type

Hub-Drive vs. Mid-Drive E‑Bikes

Hub‑drive bikes such as the RadCity 5 Plus and Ride1Up 700 Series often place the sticker on the chainstay or the bottom of the frame because the motor sits in the wheel. Mid‑drive bikes like the Specialized Turbo Levo and Bosch‑powered models usually put it on the downtube or seat tube near the motor controller. If you have a mid‑drive and the sticker is not on the downtube, lift the bike and look on the inside of the chainstay near the crankset.

Folding E‑Bikes

On folding models like the Brompton Electric or Fiido D11, the sticker is almost always on the main hinge tube or the top of the folding bracket. The frame is smaller, so you may also find it on the stem or under the battery seat. Because folding bikes are subjected to frequent hinge movement, the sticker can wear off quickly. If yours is missing, order a replacement immediately – a worn sticker is not a legal excuse.

Cargo E‑Bikes

Cargo e‑bikes such as the RadWagon 4 and Xtracycle Swoop have large frames. Check the main downtube first. If it is not there, look on the inside of the rear rack near the wheel or on the seat tube near the cargo platform. On some cargo models, the sticker is placed on a flat panel underneath the deck, which requires tilting the bike or removing the cargo platform to read it.

How to Read the Class 2 Sticker

The sticker will clearly state “Class 2” and usually include:

• Motor wattage – for example, 500W or 750W
• Maximum assisted speed – 20 mph for Class 2 throttle or pedal‑assist
• Manufacturer name and model
• Serial number or production date – not always required but common

California law does not mandate a serial number, but the classification must be legible. If the text is faded, refer to your owner’s manual for the exact classification. Keep in mind that some bikes have multiple stickers: a UL certification sticker on the battery, a compliance label on the frame, and a separate motor tag. Only the frame sticker with “Class 2” matters for enforcement.

When the Sticker Location Creates a Problem

Some manufacturers place the sticker in a spot that is easily scraped off or obscured by accessories. For instance, the sticker on the Lectric XP 3.0 battery tray can become unreadable after multiple battery removals. If that happens, the sticker is still considered valid by law, but you risk a citation because it is no longer “clearly visible.” The solution is to contact the manufacturer for a replacement sticker and then peel the old one off before applying the new one – do not overlay it.

What If the Sticker Is Missing or Damaged?

Riding an e‑bike without a valid classification sticker may result in a citation in California. If yours is missing or unreadable, take these steps:

• Contact the original manufacturer. Many will mail a free replacement sticker if you provide proof of purchase.
• Check the manufacturer’s website for a downloadable compliance label. Some brands, like Rad Power Bikes, provide a PDF to print and cut out.
• Visit the dealer where you bought the bike. They can often order a replacement sticker.
• If you cannot get a replacement, keep a printed copy of the bike’s compliance documentation, such as the user manual’s classification page, in your bag. It may satisfy an officer during a stop.

Do not attempt to make your own sticker or use a generic label. The sticker must match the bike’s actual specs and be issued by the manufacturer.

How to Verify You Have the Correct Replacement

When the new sticker arrives, compare the printed specs with your bike’s controller settings. Most e‑bike displays let you check the motor power rating. If the wattage on the sticker differs from what the display shows, do not apply it. Contact the manufacturer again – you may have received a sticker for a different model. Applying a mismatched sticker is illegal and can lead to fines.

Frequently Asked Questions

Can I ride without a Class 2 sticker in California?

No, riding without a legible classification label is illegal under AB 1096. A warning or fine is possible, especially during enforcement events.

Is the sticker required on both the bike and the battery?

Only the bike frame needs the sticker. Some batteries have separate labels for UL certification, but those are not classification stickers.

My bike is a Class 2 but the sticker says “Class 1.” What should I do?

Contact the manufacturer immediately. A mislabeled bike can lead to confusion with law enforcement. They should issue a corrected sticker at no cost.
