Class 3 Ebikes (28 MPH)
Best Class 3 eBike 28 mph: The Himiway D5 2.0 20"
Class 3 electric bikes represent the fastest street-legal tier across most of the United States. Delivering assisted speeds up to 28 mph, they allow commuters to take traffic lanes safely, beat stoplights, and significantly shorten commute times without breaking a sweat.
Featured Pick: Himiway D5 2.0 (20" Compact Full-Suspension)
While many high-speed electric bikes are bulky and hard to manage in tight spaces, the Himiway D5 2.0 20" packs full Class 3 speed capability (adjustable up to 28 mph) into an agile, compact frame with premium dual suspension and unmatched payload utility.
Why It Stands Out: Equipped with a 48V 15Ah Samsung/LG 21700 cell battery and 3.0A fast charging, the D5 2.0 20" delivers up to 70 miles of pedal assist. The switchable Torque and Cadence sensors give you natural pedal feedback or relaxed cruising, while 20×4.0" Kenda puncture-resistant tires ensure steady grip at 28 mph.

Understanding the legal distinctions between e-bike classes helps you match the right machine to your commute routes and local trail laws:
| Feature | Class 1 | Class 2 | Class 3 (Himiway) |
|---|---|---|---|
| Max Motor Speed | 20 mph | 20 mph | 28 mph |
| Drive Method | Pedal-assist only | Throttle & Pedal-assist | Pedal-assist (Throttle up to 20 mph)* |
| Motor Power Limit | Up to 750W | Up to 750W | Up to 750W (US Legal Limit) |
| Trail Access | Widest (Multi-use & trails) | Moderate (Paved paths) | Roads, on-road bike lanes, OHV routes |
| Primary Use | Parks, gravel trails, fitness | Casual leisure, flat rides | Fast urban commuting, long routes |
*Note: Many jurisdictions permit Class 3 ebikes to feature a throttle capped at 20 mph, while pedal-assist continues up to 28 mph.
Class 3 eBike Laws: Where Can You Ride?
Because Class 3 electric bikes reach 28 mph, they face distinct regulatory rules to ensure rider and pedestrian safety:
Permitted Riding Areas
- Public Roads & Streets: Legal on public roadways where bicycles are permitted. You can keep pace safely with 25 mph city traffic.
- On-Road Bike Lanes: Designated bike lanes running parallel to motorized traffic lanes.
- OHV Trails: Motorized dirt roads and routes on BLM or US Forest Service public lands.
Prohibited Riding Areas
- Pedestrian Sidewalks: Strictly prohibited across most cities to safeguard foot traffic.
- Shared Recreational Paths: Often banned on narrow, crowded multi-use greenways unless explicitly designated by local municipalities.
- Non-Motorized Singletracks: Natural dirt mountain trails strictly reserved for acoustic bikes or Class 1 eMTBs.
Essential Legal Requirements for Class 3 Ebikes
- Age Limit: Most US states mandate riders must be at least 16 years of age.
- Helmet Requirements: Helmets are legally mandatory for Class 3 operators regardless of age in many jurisdictions (such as California and Colorado).
- Speedometer: Manufacturers must provide a functioning, integrated digital display showing speed.
Motor, Battery & Range Expectations at 28 MPH
Aerodynamic drag increases exponentially at 28 mph, requiring roughly double the electrical energy consumed at 20 mph. Real-world range depends heavily on how power is managed:
⚡ 750W Motor & Torque Delivery
Federal law caps street-legal e-bikes at 750W continuous output. To reach and hold 28 mph on grades, look for motors offering 85Nm to 90Nm of torque (like the D5 2.0). A torque sensor provides proportional, seamless boost rather than the abrupt surge of basic cadence-only sensors.
🔋 48V Samsung/LG Battery Capacity
A 48V system is essential for delivering the RPM needed for 28 mph without overheating. A high-quality 720Wh to 960Wh pack provides 25–35 miles at full 28 mph throttle/turbo speeds, and 60–75+ miles when using lower PAS levels.
Frequently Asked Questions
Do I need a driver’s license or insurance to ride a Class 3 ebike?
No. Under US federal law and standard three-tier state legislation, Class 3 ebikes are legally classified as bicycles, not motor vehicles. You do not need a driver’s license, motor vehicle registration, or state insurance to operate one.
Can a Class 3 ebike have a throttle?
Yes, under many state laws (such as California), a Class 3 ebike may feature a throttle as long as the throttle assistance disengages at 20 mph, while pedal assist continues up to 28 mph.
Why are hydraulic disc brakes necessary on a Class 3 ebike?
Traveling at 28 mph on an 80 lb ebike creates significant momentum. Hydraulic disc brakes with 180mm or 203mm rotors (like the Tektro system on the D5 2.0) provide consistent, immediate stopping power in wet or dry conditions with minimal hand strain.
What is the top speed if the battery runs out?
If the battery runs out, the motor stops, but the bike functions as a regular bicycle via the mechanical 8-speed Shimano drivetrain. Your speed will depend entirely on your own leg power.
