Motorized Bicycle Laws in Texas start with one key question: does your vehicle qualify as an electric bicycle under Texas Transportation Code Chapter 664? If it has fully operable pedals, a motor of fewer than 750 watts, and a top assisted speed of 28 mph or less, Texas treats it under the state's e-bike rules. If it falls outside that definition, check Texas DPS and TxDMV requirements before riding on public roads.

| Texas e-bike definition | Fully operable pedals, electric motor of fewer than 750 watts, and top assisted speed of 28 mph or less. |
| Texas class system | Texas recognizes Class 1, Class 2, and Class 3 electric bicycles. |
| License / registration | For Chapter 664 electric bicycles, the official Texas sources cited here focus on classification and equipment rules. If your vehicle falls outside the e-bike definition, verify the exact license and registration rules with Texas DPS and TxDMV before riding. |
| Helmet / age / passenger rules | No universal statewide helmet or passenger rule is clearly stated in the Texas sources cited below for every e-bike situation. Check current local, trail, campus, and property-specific rules before riding. |
| Power / speed limits | The motor must be under 750 watts and the top assisted speed must be 28 mph or less. Class 1 and Class 2 are limited to 20 mph or less, while Class 3 is more than 20 mph but less than 28 mph. |
| Where you can ride | Statewide ride-location rules can still vary by city, park, campus, trail operator, or private property owner. Always check posted local access rules before riding. |
| Local-rules caveat | Even if your bike qualifies as a Texas e-bike under Chapter 664, cities, trails, campuses, and private property can still impose additional rules. |
Texas Transportation Code § 664.001 defines an electric bicycle as a bicycle with fully operable pedals, an electric motor of fewer than 750 watts, and a top assisted speed of 28 mph or less.
Texas also uses a three-class system that makes Motorized Bicycle Laws in Texas more specific than the older two-type language still floating around online:
| Texas class | How the motor works | Top assisted speed |
|---|---|---|
| Class 1 | Motor assists only while pedaling | 20 mph or less |
| Class 2 | Motor may propel the bike without pedaling | 20 mph or less |
| Class 3 | Motor assists only while pedaling | More than 20 mph but less than 28 mph |
If your machine does not fit that definition—for example, it is gas-powered, does not have fully operable pedals, exceeds the wattage cap, or exceeds the assisted-speed cap—do not assume the Texas e-bike rules apply.
If your bike has pedals, stays under 750 watts, and stays within the Texas assisted-speed limits, start with Chapter 664. That chapter is the clearest official source for how Texas classifies e-bikes.
If your vehicle falls outside Texas's electric-bicycle definition, verify the exact classification with Texas DPS and TxDMV before riding on public roads. Texas DPS publishes separate Class M motorcycle licensing guidance, and TxDMV separately publishes vehicle-registration guidance for mopeds and motorcycles.
Texas requires manufacturers and sellers of Class 3 electric bicycles to ensure the bike is equipped with a speedometer. Texas also requires permanent e-bike labeling that identifies the class, top assisted speed, and motor wattage. If a bike is modified in a way that changes its motor-powered capability, the label must be updated.
State law is only part of the answer. A path, park, campus, HOA, or private property owner can still post narrower access rules, so check the local signage or operator rules before riding.
Before riding in places like Austin, Dallas, Houston, San Antonio, on local trails, on university property, or in parks, check the posted local or property-specific rules. Even when Texas state law allows a certain class of e-bike, local access rules can still be narrower.
