SUPER73-Z Miami Core 500W Electric Bike – 20 MPH Compact Neighborhood Explorer with 480Wh UL2271 Battery
Product Description
The SUPER73-Z Miami Core is a compact electric bike that blends vintage minibike styling with modern electric-bike technology. Designed primarily for urban commuting, neighborhood riding, beach cruising, and recreational use, the Miami Core offers comfortable ergonomics, a lightweight aluminum frame, and a simplified single-speed drivetrain.
Powered by a 500-watt nominal rear hub motor, the bike delivers smooth acceleration through a thumb throttle and pedal assist system. Its 480Wh (48V 10Ah) removable lithium-ion battery is UL2271 compliant and provides an estimated riding range of 25–35 miles, depending on rider weight, terrain, riding mode, weather, and throttle usage.
Unlike the Miami SE or Adventure Series, the Miami Core uses a rigid front fork, making it lighter and simpler while providing efficient power transfer on paved roads and smooth bike paths. Mechanical disc brakes, oversized 20-inch Trooper tires, integrated battery mounting, and a low seat height create a comfortable riding experience for riders looking for a stylish everyday e-bike.
The Miami Core is ideal for riders who prioritize easy handling, minimal maintenance, and classic SUPER73 styling without the added complexity of suspension or multiple gears.
500W Rear Hub Motor
The bike is equipped with a 500-watt nominal brushless rear hub motor engineered for smooth, predictable acceleration and quiet operation.
The motor delivers power directly to the rear wheel through a maintenance-friendly hub-drive system, reducing drivetrain wear compared to mid-drive motors.
It is suitable for:
- Daily commuting
- Neighborhood riding
- Beach paths
- Campus transportation
- Recreational cruising
- Urban streets
The motor is controlled electronically to provide consistent acceleration while helping maximize battery efficiency.
20 MPH Class 2 Performance
The SUPER73-Z Miami Core is configured as a Class 2 electric bicycle with a factory top speed of 20 MPH using throttle or pedal assist where permitted. Regional regulations may affect available ride modes.
This speed is suitable for:
- Urban commuting
- Bike lanes
- Neighborhood travel
- Parks where permitted
- Recreational riding
Always follow local e-bike laws and wear appropriate safety equipment.
480Wh UL2271 Battery
The removable 480Wh (48V 10Ah) lithium-ion battery is certified to UL2271, providing dependable power and convenient charging.
Benefits include:
- Removable design
- Home or office charging
- Secure frame mounting
- Lightweight construction
- Improved safety certification
Charging time is approximately 5 hours using the supplied charger.
Estimated 25–35 Mile Range
The Miami Core offers an estimated riding range of 25–35 miles on a full charge. Actual range depends on:
- Rider weight
- Terrain
- Tire pressure
- Wind conditions
- Ambient temperature
- Riding speed
- Pedal-assist usage
- Throttle usage
- Battery age
Frequent full-throttle riding and steep hills will reduce total range.
Lightweight Aluminum Frame
The bike uses a durable aluminum frame that combines strength with reduced weight.
Advantages include:
- Corrosion resistance
- Improved maneuverability
- Lower overall weight
- Stable handling
- Long service life
The compact frame geometry provides a relaxed riding position for casual urban travel.
Single-Speed Drivetrain
The Miami Core uses a single-speed drivetrain, eliminating derailleurs and gear adjustments.
Benefits include:
- Reduced maintenance
- Simpler operation
- Quiet riding
- Reliable chain alignment
This configuration is ideal for relatively flat urban environments and neighborhood riding.
Rigid Front Fork
Unlike the SE version, the Core model features a rigid fork instead of front suspension.
Advantages include:
- Lower weight
- Fewer maintenance requirements
- Better pedaling efficiency
- Clean minimalist appearance
The large balloon tires help absorb normal road vibration.
Mechanical Disc Brakes
The bike is equipped with Tektro 2-piston mechanical disc brakes.
These brakes provide:
- Reliable stopping power
- Consistent wet-weather performance
- Easy adjustment
- Low maintenance
Brake pads should be inspected regularly and replaced when worn.
20×4-Inch Trooper Tires
Oversized Trooper 20×4-inch fat tires improve comfort and traction across:
- Asphalt
- Concrete
- Bike paths
- Packed dirt
- Gravel
- Beachside roads
The larger tire volume helps absorb minor road imperfections despite the rigid frame.
Thumb Throttle
A handlebar-mounted thumb throttle allows electric propulsion without pedaling where regulations permit.
Throttle control enables:
- Smooth starts
- Convenient cruising
- Reduced rider fatigue
- Better control in stop-and-go traffic
LED Lighting
Depending on the selected color configuration, the Miami Core may include an integrated LED headlight and taillight. Lighting availability varies by colorway and production version.
Comfortable Riding Position
The long bench-style saddle and upright handlebars create a relaxed riding posture suitable for:
- Daily commuting
- Leisure rides
- Campus transportation
- Neighborhood cruising
The low 28-inch seat height makes mounting and dismounting easier for many riders.
