Ebike classes sort electric bikes by how the motor helps and when it stops. Class 1 bikes assist only while you pedal, up to 20 mph. Class 2 bikes add a throttle and also stop at 20 mph. Class 3 bikes assist only while you pedal, up to 28 mph. In most states, e-bikes that fit these classes are treated much like regular bicycles, with no license or registration needed, but the rules vary by state and they change.
This guide explains the ebike classes, how they compare, what states typically require on licenses, ages and helmets, and where you can ride. It is general information, not legal advice. Check your state and local rules before you ride.
Ebike classes at a glance: Class 1, 2 and 3
The three-class system was developed by the bike industry and is promoted by the trade group PeopleForBikes, which also publishes a comparison of state e-bike laws. California’s version, in Vehicle Code Section 312.5, is a typical example:
| Class | Throttle? | Motor stops helping at | Notes (California) |
|---|---|---|---|
| Class 1 | No, pedal assist only | 20 mph | Treated much like a bicycle |
| Class 2 | Yes, can move without pedaling | 20 mph | Treated much like a bicycle |
| Class 3 | No, pedal assist only | 28 mph | Speedometer required; riders 16+; helmet for all riders |
California’s definition also limits the motor to 750 watts. The federal consumer-product definition of a “low-speed electric bicycle” in 15 U.S.C. 2085 uses the same 750 W cap, requires working pedals, and limits speed on motor power alone to under 20 mph with a 170-pound rider. Federal law covers how the bike is made and sold; state and local laws decide where and how you ride it.
Class 1 vs Class 2 ebike
The difference between Class 1 and Class 2 is the throttle. Both stop assisting at 20 mph.
- Class 1 only adds power while you pedal. Because it behaves most like a regular bike, it tends to have the widest access. For example, National Park Service superintendents can open a trail to Class 1 e-bikes only (NPS).
- Class 2 adds a throttle, so you can ride without pedaling. That helps when starting from a stop, on hills, or for riders with knee or joint limits. In national parks, Class 2 riders may not rely on the throttle alone for extended periods except where public motor vehicles are allowed.
Many bikes, including several we sell, have both pedal assist and a throttle, which puts them in Class 2 when the motor is limited to 20 mph.
Class 2 vs Class 3 ebike
Class 3 trades the throttle for more assisted speed: pedal assist up to 28 mph. That suits longer commutes on roads, but it comes with more rules. In California, Class 3 riders must be at least 16 and wear a helmet, and the bike needs a speedometer (Vehicle Code 21213). Local governments and park agencies can also keep Class 3 bikes off certain paths and trails.
Some bikes can be switched between classes in the display menu. The Himiway D5 2.0, for example, ships at 20 mph and has Class 1, 2 and 3 settings up to 28 mph. Whatever the bike can do, ride it in the class your local rules allow.
Do you need a license for an electric bike?
In most states, no. E-bikes that fit the class definitions are generally regulated like bicycles. California, for example, exempts e-bike riders from driver’s license, registration, license plate and insurance requirements (Vehicle Code 24016).
There are exceptions, and they are changing:
- New Jersey. In January 2026, New Jersey passed a law that PeopleForBikes describes as the most restrictive in the US. According to PeopleForBikes, it requires registration and a driver’s license for all e-bikes, plus insurance for Class 2 and Class 3, although implementation details were still unclear in early 2026. Its FAQ on the law tracks updates.
- Bikes outside the classes. A bike with a motor above the state’s power limit, or one that goes faster than 28 mph under motor power, may be treated as a moped or motor vehicle, which can bring license, registration and insurance requirements.
Even where insurance is not required, it is worth checking whether your homeowner’s or renter’s policy covers an e-bike, or whether a separate policy makes sense.
Age and helmet rules
Age and helmet rules are set by each state, and some cities add their own. California is a useful reference:
- Riders under 18 must wear a helmet on any bicycle, including Class 1 and 2 e-bikes (Vehicle Code 21212).
- Class 3 riders must be at least 16, and every Class 3 rider and passenger must wear a helmet, regardless of age (Vehicle Code 21213).
Other states set different ages or no minimum at all. If you are buying for a teenager, check your state’s rules first.
California e-bike laws in brief
Because California is a large market and its rules are often copied, here is a quick summary of the state’s ebike classes and laws, drawn from the Vehicle Code:
- Three classes, with a 750 W motor limit (Section 312.5).
- No driver’s license, registration, plates or insurance for e-bikes (Section 24016).
- Manufacturers must label the class; if a bike is modified to change its speed or how the motor engages, the label must be replaced (Section 24016).
- Helmets for all riders under 18, and for all Class 3 riders and passengers; Class 3 riders must be 16 or older (Sections 21212 and 21213).
- Local authorities can allow or ban e-bikes, or specific classes, on bike paths, equestrian and hiking trails (Section 21207.5).
E-bike laws by state: how to check your rules
Most states now use the three-class system, but details such as age limits, helmet rules and path access differ. Rules come from several layers, so check each one that applies to where you ride:
| Layer | What it controls | Where to check |
|---|---|---|
| Federal | How e-bikes are built and sold; rules on federal land | 15 U.S.C. 2085; National Park Service; US Forest Service |
| State | Classes, license and registration, age and helmet rules | Your state vehicle code or DMV; the PeopleForBikes state law comparison |
| City or county | Sidewalks, local paths, speed limits, parking | Your city or county website |
| Park or trail manager | Which classes can use which trails | Posted signs and the park’s website |
Are e-bikes allowed on trails?
Sometimes. Trail access depends on who manages the land:
- National parks. E-bikes may be allowed only where regular bicycles are allowed, and never in wilderness areas. Superintendents can allow some classes and not others (NPS).
- National forests. The US Forest Service allows e-bikes on roads and trails open to motor vehicles. Its Motor Vehicle Use Maps show which ones those are. Non-motorized trails stay closed to e-bikes unless a local office designates them otherwise.
- State and local parks. Rules vary widely. In California, local authorities and the state parks department can restrict e-bikes or specific classes on trails they manage.
Look for posted signs at the trailhead and check the land manager’s website before you go. Hunters and off-road riders should pay particular attention to national forest maps.
Which class is each bike we sell?
Always check the class label and the display settings on the bike itself. Based on published specifications:
- Himiway D5 2.0 family (D5 2.0, D5 2.0 ST, D5 2.0 Camo): 750 W motor with Class 1, 2 and 3 settings. Ships at 20 mph.
- Himiway A3 and Himiway B3: 500 W motors with a thumb throttle, according to Himiway. A throttle bike limited to 20 mph fits Class 2. Himiway lists the A3’s top speed as “20+ mph”, so confirm the speed setting on your bike.
- Himiway C1 Kids: a children’s e-bike with a throttle and a top speed of 15 mph in its high mode.
- Himiway D7 (Cobra) and D7 Pro: 1000 W motors, above the 750 W limit used in California and in the federal definition. In states that use that cap, they may not qualify as e-bikes for road and path rules. Check locally before riding them on public roads, bike paths or non-motorized trails.
- Italwin and Wayel bikes, such as those in our commuter and city e-bikes range: built to the European spec with 250 W motors and pedal assist limited to 25 km/h (15.5 mph), well under the 20 mph Class 1 cutoff.

FAQ
What are the different ebike classes?
Class 1 is pedal assist to 20 mph, Class 2 adds a throttle with a 20 mph limit, and Class 3 is pedal assist to 28 mph. Most states use these definitions, usually with a 750 W motor limit.
Do I need a license or registration for an e-bike?
In most states, no, as long as the bike fits the class definitions. New Jersey is a notable exception after its 2026 law, and bikes outside the classes may be treated as mopeds or motor vehicles.
Which e-bike class is best for commuting?
Class 3 gets you to 28 mph on roads, which helps on longer commutes. Class 1 or Class 2 offers wider access to paths and trails. Many riders choose a bike that can switch between classes.
Can kids ride e-bikes?
It depends on the state and the class. California bars riders under 16 from Class 3 bikes and requires helmets for all riders under 18. Kids’ e-bikes like the Himiway C1 are limited to lower speeds.
Are e-bikes allowed on hiking trails?
Usually not unless the trail is open to bicycles or motor vehicles, depending on the land manager. National parks follow bicycle access; national forests follow motor vehicle access. Check signs and local rules.
Do e-bike laws change?
Yes, often. The National Conference of State Legislatures has tracked a steady stream of state e-bike legislation since 2015. Check your state’s current rules before you buy and before you ride somewhere new.
