The Three-Class E-Bike System Explained
The United States has adopted a standardized three-class system that categorizes electric bikes based on their speed capabilities and motor assistance type. All classes limit the motor's power to 1 horsepower (750W), but they differ significantly in how that power is delivered.
Class 1 E-Bikes: Pedal-Assist Only
Class 1 e-bikes provide pedal assistance only up to 20 mph. These bikes require continuous pedaling to activate the motor, offering a natural cycling experience with electric assistance. The motor automatically cuts power once you reach 20 mph, encouraging active riding while providing support when needed.
Key Features:
- Pedal-assist only (no throttle)
- Maximum assisted speed: 20 mph
- Motor power: Up to 750 watts
- Most trail and path access allowed
Class 1 e-bikes are ideal for riders who want to maintain an active cycling experience while enjoying the benefits of electric assistance. They're permitted on most bike paths and trails where traditional bicycles are allowed, making them versatile for recreational and commuting purposes.
Class 2 E-Bikes: Throttle and Pedal-Assist
Class 2 e-bikes combine pedal assistance with throttle control, allowing riders to choose between active pedaling and motor-only operation. Like Class 1, these bikes have a maximum assisted speed of 20 mph, but the addition of a throttle provides more flexibility in how you ride.
Key Features:
- Both pedal-assist and throttle options
- Maximum assisted speed: 20 mph (throttle and pedal-assist)
- Motor power: Up to 750 watts
- Allowed on most bike lanes and paths
The Tamobyke V20 exemplifies excellent Class 2 e-bike design with its 1000W motor, 48V 15AH battery, and combination of pedal-assist and throttle control. This versatility makes Class 2 e-bikes perfect for riders who may need breaks from pedaling or want the option to accelerate quickly from stops.
Class 3 E-Bikes: High-Speed Pedal-Assist
Class 3 e-bikes are the fastest legal electric bikes, providing pedal assistance up to 28 mph. These bikes focus on speed and efficiency, making them ideal for commuting and longer-distance travel. Recent legislation in California (SB No.1271) that came into effect January 2025 clarifies that Class 3 e-bikes cannot have a throttle in addition to their 28 mph pedal-assist capabilities.
Key Features:
- Pedal-assist only (no throttle above 20 mph)
- Maximum assisted speed: 28 mph
- Motor power: Up to 750 watts
- Restricted from some bike paths and trails
The Tamobyke TB20 represents premium Class 3 performance with its powerful 1500W motor, 48V 25AH battery, and impressive 35 mph top speed capability. With up to 124 miles of range, it's designed for serious riders who demand maximum performance and distance.

Legal Considerations and Where You Can Ride
Understanding where you can ride each class is essential for legal compliance and safety:
Class 1 and 2 Access:
- Most bike lanes and bike paths
- Multi-use trails (varies by location)
- Roads where bicycles are permitted
- Some national and state parks (check local regulations)
Class 3 Restrictions:
- Generally limited to roads and on-road bike lanes
- Restricted from most multi-use trails and paths
- May require helmet use (varies by state)
- Some areas have additional age restrictions
More states are following California and Oregon's lead in prohibiting throttles on Class 3 e-bikes, limiting them to pedal-assist only, reflecting safety concerns about higher-speed operation.
Choosing the Right Class for Your Needs
Select Class 1 If You:
- Want maximum trail and path access
- Prefer an active, traditional cycling experience
- Ride primarily for fitness and recreation
- Need a bike for areas with strict e-bike regulations
Choose Class 2 If You:
- Want the flexibility of throttle and pedal-assist
- Need occasional breaks from pedaling
- Commute in urban environments with frequent stops
- Want the best balance of power and accessibility
Opt for Class 3 If You:
- Prioritize speed and efficiency for commuting
- Ride primarily on roads and bike lanes
- Need to cover longer distances quickly
- Want maximum performance from your e-bike motor system
Future of E-Bike Classifications
The e-bike industry continues evolving, with manufacturers like Tamobyke leading innovation in battery technology and motor efficiency. States are increasingly clarifying whether power limitations refer to "nominal" or "peak" power, resolving a significant ambiguity that has caused confusion.
As regulations become more standardized and technology advances, we expect to see continued improvements in range, power delivery, and smart features across all classes.
