Answer: Super73 electric bicycles typically reach speeds of 20–28 mph (32–45 km/h), depending on the model and regional regulations. Higher-end variants like the Super73-R Series achieve 28 mph in “Unrestricted Mode,” while standard modes cap at 20 mph for compliance with local e-bike laws. Speed is influenced by terrain, rider weight, battery charge, and motor efficiency.

What Are the Speed Specifications of Super73 Models?
Super73 offers multiple models with varying speed capabilities:
- Super73-R Series: Up to 28 mph (45 km/h) in Unrestricted Mode
- S2 and Z Series: 20–24 mph (32–38 km/h) default, adjustable via app
- EU/UK Models: Limited to 15.5 mph (25 km/h) to meet regional laws
What Factors Influence the Super73’s Top Speed?
Key factors include:
- Motor Power: 750W–2,000W motors affect acceleration and torque
- Battery Voltage: 48V–72V systems determine energy output
- Rider Weight: Heavier loads reduce speed by 5–10%
- Terrain: Inclines can cut speed by 15–20% versus flat surfaces
How Do Legal Restrictions Affect Super73 Speed?
In the U.S., Class 2 e-bikes (throttle-assisted) are capped at 20 mph, while Class 3 (pedal-assist) allow 28 mph. European models are restricted to 15.5 mph. Super73 uses geofencing software in some regions to enforce limits, though “Unrestricted Mode” voids warranties and may violate traffic laws.
Legal frameworks vary significantly. For example, California mandates speedometers for Class 3 e-bikes, while New York prohibits throttles entirely. In Germany, tampering with speed limiters can result in €1,000 fines and vehicle impoundment. Super73’s geofencing technology adjusts speed caps automatically when crossing borders between U.S. states or EU countries. Riders should verify their local e-bike classifications, as exceeding 28 mph often reclassifies the vehicle as a moped or motorcycle, requiring registration, insurance, and a driver’s license.
| Region | Speed Limit | Penalty for Violation |
|---|---|---|
| USA (Class 3) | 28 mph | $300 fine |
| European Union | 15.5 mph | €1,000+ fines |
| Australia | 15.5 mph | Vehicle confiscation |
How Does the Super73 Compare to Other High-Speed E-Bikes?
Competitors like Juiced Bikes (30 mph) and Delfast Top 3.0 (50 mph) surpass Super73 in raw speed. However, Super73 balances speed with retro styling, customizable parts, and a 75–100-mile range—making it ideal for urban commuting rather than extreme performance.
While the Delfast Top 3.0 dominates in acceleration (0-30 mph in 4.2 seconds), it weighs 128 lbs versus Super73-RX’s 77 lbs. Super73’s modular design allows for easier upgrades like 11-speed cassettes or dual battery systems. The table below highlights key differences:
| Model | Top Speed | Range | Weight |
|---|---|---|---|
| Super73-RX | 28 mph | 75 miles | 77 lbs |
| Juiced Hyperscorpion | 30 mph | 70 miles | 92 lbs |
| Delfast Top 3.0 | 50 mph | 200 miles | 128 lbs |
What Safety Precautions Are Recommended at High Speeds?
At 28 mph, riders should:
- Use DOT-certified helmets
- Enable hydraulic disc brakes (203mm rotors)
- Install 5,000-lumen headlights for visibility
- Avoid “Unrestricted Mode” on public roads
Can Upgrades Boost the Super73’s Speed Beyond Factory Limits?
Aftermarket controllers (e.g., Nucular 24F) and 72V battery swaps can push speeds to 35–40 mph, but this voids warranties, risks motor burnout, and may breach e-bike classifications—potentially requiring motorcycle licenses.
How Does Terrain Impact Real-World Speed Performance?
On 10% inclines, Super73’s speed drops to 12–15 mph even with pedal assist. Sandy or muddy surfaces reduce efficiency by 30%, while smooth asphalt maximizes velocity. The 4.9-inch suspension travel helps maintain stability but doesn’t mitigate speed loss on rough trails.
What Do GPS Data Logs Reveal About Super73 Speed Consistency?
Third-party telemetry shows 20 mph speeds are sustainable for 1.5 hours on a full charge, while 28 mph drains the 960Wh battery in 45 minutes. Speed variance is ±2 mph under consistent throttle, but frequent stops/starts reduce range by 40%.
“Super73’s 28 mph cap is a sweet spot between thrill and practicality. Pushing beyond factory limits risks overheating the 2,000W mid-drive motor, which lacks liquid cooling. Riders often underestimate how tire pressure (20–30 PSI) and lubrication affect drivetrain efficiency at high speeds.” — E-Bike Industry Engineer
FAQs
- Does the Super73 require a license to ride?
- No, if operated under 28 mph in regions where it’s classified as a Class 3 e-bike.
- Can the speed limiter be removed permanently?
- Yes via aftermarket hacks, but this may violate traffic laws.
- How long does the battery last at top speed?
- Approximately 45–60 minutes at 28 mph.
