Class 1, 2 and 3 in brief
Under the three-class system most U.S. states use: Class 1 is pedal assist only, up to 20 mph. Class 2 adds a throttle, also limited to 20 mph. Class 3 is pedal assist up to 28 mph, and in most states the throttle (if any) is limited to 20 mph or not allowed. All three classes are typically capped at 750W of motor power. Our classes guide covers the rules in more depth.
Things to know before buying Class 3
Where you can ride. Class 3 bikes are often allowed in bike lanes and on roads but may be barred from multi-use paths and trails. Check state and local rules for your route.
Age and helmet rules. Many states set a minimum age (often 16) for Class 3 and require helmets for Class 3 riders.
Brakes matter more. Kinetic energy rises with the square of speed, so stopping from 28 mph takes nearly twice the energy of stopping from 20 mph. Hydraulic disc brakes are strongly preferred.
Range drops at speed. Wind resistance climbs steeply above 20 mph. Riding at 28 mph can use far more energy per mile than cruising at 18–20 mph, so expect less range than the claim.
Insurance and theft. Faster, pricier bikes attract thieves. Check whether your homeowner’s or renter’s policy covers e-bikes, and budget for a strong lock.
Throttle on Class 3 bikes
Several bikes here have a throttle as well as Class 3 pedal assist. In class-switching bikes, the throttle is typically limited to 20 mph, keeping the bike within Class 2 rules when using it. Check each product page and your local laws for how throttles are treated.
Frequently asked questions
What is the best Class 3 e-bike?
On published specs, the Velotric Discover 3: Class 1, 2 or 3, 730Wh, 440 lb and UL 2849 & UL 2271.
Is a Class 3 e-bike worth it?
If you commute on roads with traffic moving 25–35 mph, the extra assisted speed is useful. If you ride mostly on paths, a Class 1 or 2 bike may be all you need and allowed in more places.
Can I switch an e-bike between classes?
Many bikes we track can, including the Velotric Discover 3, Lectric XPress2 and Lectric XP4 750 (long-range). Changing classes is done in the display or app per the brand’s instructions. Modifying a bike beyond its intended class may void the warranty and break local laws.
