Super73 electric bikes combine retro styling with modern tech, featuring 750W-2000W motors, 20-75+ mile ranges, and modular batteries. Key specs include hydraulic disc brakes, 5-speed pedal assist, throttle modes, and customizable frames. Designed for urban and off-road use, they support up to 325 lbs and integrate smart features like app connectivity. Learn more below.
How Does Motor Power and Performance Vary Across Super73 Models?
Super73 models range from 750W (S2, ZX) to 2000W (RX Mojave) motors. The RX series offers peak torque of 160 Nm for off-road terrain, while the S2 delivers 130 Nm for urban commuting. All motors provide instant acceleration via thumb throttles and support pedal assist up to 28 mph (Class 3) in the U.S., with European models capped at 15.5 mph (Class 1).
The S2 model’s 750W motor achieves 0-20 mph in 4.2 seconds, ideal for stop-and-go traffic. For riders seeking extreme performance, the RX Mojave’s 2000W setup propels the bike up 35-degree inclines without pedal assistance. Recent firmware updates allow torque customization through the app – commuters can prioritize efficiency (reducing power draw by 18%) while off-road enthusiasts maximize acceleration. Thermal sensors prevent overheating during sustained climbs, automatically reducing output if motor temperatures exceed 150°F.
What Battery Technology Powers Super73 E-Bikes?
Super73 uses 48V/960Wh lithium-ion batteries with Samsung/LG cells. The RX models feature dual-battery compatibility for 1440Wh total capacity, enabling 75+ mile ranges. Charging takes 4-6 hours via standard ports. Batteries are lockable, waterproof (IP67), and removable for security. The app tracks real-time battery health, charging cycles, and estimated range based on riding mode.
The patented Battery Management System (BMS) employs cell-level monitoring to prevent overcharging and balance energy distribution. In cold weather conditions (below 40°F), the system automatically engages internal heaters to maintain optimal performance. Users can enable “Range Saver” mode through the app, which limits top speed to 18 mph but extends battery life by 22%. Third-party testing shows the 960Wh battery retains 92% capacity after 500 charge cycles when maintained between 20-80% charge levels.
Which Frame Materials and Designs Define Super73 Bikes?
All models use 6061 aluminum alloy frames with hydroformed tubing. The step-through design (ZX series) has a 30″ standover height, while adventure models (RX) feature reinforced double-diamond frames. Weight varies from 70 lbs (ZX) to 95 lbs (RX). Frames include integrated LED lighting, rear cargo racks, and compatibility with aftermarket mods like suspension forks or child seats.
How Do Speed Modes and Pedal Assist Systems Work?
Super73 offers 4 ride modes: Eco (15 mph), Tour (20 mph), Sport (28 mph), and Unlimited (unrestricted, off-road only). Pedal assist uses a 12-magnet cadence sensor with 5 levels. Throttle-override lets riders switch between pedal-free acceleration and exercise modes. Custom modes via the app allow speed limit adjustments and torque curve tuning for steep hills.
What Safety Features Are Included in Super73 E-Bikes?
All models include Tektro hydraulic disc brakes with 180mm rotors, automatic brake light activation, and ABS-like motor cutoff. The RX series adds full suspension (120mm travel) and knobby tires for traction. Integrated turn signals (EU models) and 1,500-lumen headlights enhance visibility. The app includes anti-theft GPS tracking and remote lock/unlock capabilities.
Can Super73 Bikes Be Customized With Aftermarket Parts?
Yes. Super73’s “Mod Shop” offers 200+ OEM upgrades: extended seats, 20″x4.5″ fat tires, fenders, and suspension forks. Third-party mods like 35Ah batteries or 1,500W controllers are popular. The open-source CAN bus system allows software tweaks, though this voids warranties. Frame geometry supports aftermarket handlebars, pegs, and cargo trailers up to 100 lbs capacity.
How Do Super73 Models Compare to Competitors Like Rad Power or Juiced?
Super73 outperforms Rad Power’s 750W bikes in torque (130Nm vs 80Nm) but costs 30% more. Juiced Bikes match Super73’s power but lack modular batteries. Unique to Super73: moto-style seating, app-enabled diagnostics, and California-based assembly. Competitors often use generic frames; Super73’s proprietary designs have been stress-tested to MIL-STD-810G standards for military gear durability.
| Model | Motor Power | Max Range | Weight |
|---|---|---|---|
| S2 | 750W | 40 miles | 73 lbs |
| RX Mojave | 2000W | 75 miles | 95 lbs |
| ZX | 750W | 35 miles | 70 lbs |
What Maintenance Routines Extend Super73 Battery Life?
Store batteries at 50% charge in 50-77°F environments. Deep-cycle every 30 charges by draining to 5% before recharging. Clean terminals monthly with isopropyl alcohol. Avoid sustained 100% throttle usage, which overheats cells. Replace batteries after 800 cycles or when capacity drops below 70%. The app sends maintenance alerts based on usage patterns and environmental factors.
Are Super73 Bikes Covered Under Warranty?
Super73 offers 1-year comprehensive warranties covering motor, battery, and frame defects. Extended 2-year battery warranties cost $199. Exclusions include water damage beyond IP67 ratings, unauthorized modifications, and tire wear. Customers report 3-5 day response times for warranty claims. Crash replacement discounts (30% off parts) apply within the first 90 days of ownership.
“Super73 redefined the e-bike market by blending motorcycle aesthetics with legit power. Their torque figures rival some electric motorcycles, yet they maintain bicycle practicality. The RX’s dual-battery system is industry-leading—it’s the only production e-bike I’ve tested that can handle 50+ miles of single-track trails without a recharge.”

FAQs
- How fast can a Super73 bike go?
- U.S. models reach 28 mph in pedal assist mode (Class 3) or 20 mph via throttle-only (varies by state). Off-road/unrestricted modes unlock 33+ mph. EU models are limited to 15.5 mph to comply with Class 1 regulations.
- Are Super73 bikes street legal?
- Yes in all 50 U.S. states when using factory settings. Throttle-only operation requires helmet and minimum age 16 in some states. Always check local e-bike classification laws before modifying speed limits.
- Can you ride Super73 bikes in the rain?
- Yes. All components are IP67-rated for heavy rain. Avoid submerging the battery/motor in water deeper than 3 feet. Dry connectors after riding to prevent corrosion.
