Super 73 models range from around $1,400 to $2,000 depending on which version you choose

Super 73 makes three main electric bike lines: the S2, the RX, and the Z. The S2 is their entry-level model and typically costs less than their mid-range RX. The RX sits in the middle. The Z is their premium option with the highest price tag. Exact pricing shifts based on sales, stock, and where you buy, so you'll see variation between their official website, Amazon, and local retailers.

What you're actually paying for is a motorized bike designed to look like a vintage moped or cruiser rather than a traditional electric bike. Super 73 bikes use a rear hub motor (the motor sits in the back wheel), a pedal-information system, and a battery that mounts low on the frame. They're heavier than regular bikes—typically 50 to 65 pounds depending on the model—and they're built for casual riding on flat terrain rather than climbing hills or off-road use.

Key Takeaways

  • Super 73 S2 models start around $1,400, RX models around $1,700, and Z models around $2,000, though prices vary by retailer and current promotions.
  • The motor is a rear hub design that provides pedal information up to 20 mph on most models, limited by US federal law for electric bikes.
  • Battery range depends on how much you pedal versus relying on motor power, but expect 20 to 40 miles per charge on most models.
  • You'll need to budget for a helmet, lock, and regular maintenance like brake adjustments and tire replacements, which add to the total cost of ownership.
  • Super 73 bikes are designed for short urban trips and casual riding, not for commuting long distances or climbing steep hills regularly.

What the motor and battery actually do

Super 73 bikes use a rear hub motor that provides power when you pedal. You still have to pedal—the motor doesn't work if you're just sitting still. The motor kicks in to help you move forward, which means you're doing less work than you would on a regular bike. The motor cuts off at 20 mph on most models because that's the federal speed limit for electric bikes classified as bicycles rather than mopeds.

The battery is a lithium-ion pack that stores energy and feeds it to the motor. On the S2, you get a smaller battery that gives you roughly 20 to 30 miles of range if you're mostly using the motor. On the RX and Z, the battery is larger and can push you closer to 40 miles. But range is not a fixed number—it depends heavily on how much you pedal, your weight, terrain, and weather. If you pedal hard and use the motor lightly, you'll go farther. If you rely mostly on the motor, the battery drains faster.

How Super 73 pricing compares to other electric bikes

Super 73 bikes cost more than basic electric bikes from brands like Rad Power or Lectric, which start around $800 to $1,200. You're paying extra for the moped-style design, the heavier frame, and the brand name. You're not paying for better performance or range—you're paying for aesthetics and the specific riding experience Super 73 targets.

If you want a lighter, faster electric bike for actual commuting, brands like Trek or Specialized make electric bikes that cost $2,500 to $4,000 but offer better motors, lighter weight, and more versatility. Super 73 is positioned between cheap entry-level e-bikes and serious commuter bikes. The choice depends on what you actually want to do: casual neighborhood rides and short trips, or longer commutes and varied terrain.

What you need to buy separately

The bike itself is not the only cost. You'll need a helmet—a good one costs $100 to $200 and is not optional if you're riding a motorized bike. You'll need a lock, especially if you're leaving the bike anywhere public. A decent U-lock runs $50 to $100. You'll also want lights if you ride at night, which adds another $30 to $80.

Maintenance costs are real too. Tires wear out faster on electric bikes because they're heavier. Brake pads need replacement more often. The battery itself will eventually degrade and need replacement, which typically costs $400 to $800 depending on the model. If you're not comfortable doing basic maintenance yourself, you'll be paying a bike shop for labor on top of parts. Budget $100 to $200 per year for routine maintenance and repairs if you ride regularly.

Where to actually buy and what warranty covers

You can buy Super 73 bikes directly from their website, from Amazon, or from some local bike shops that carry the brand. Buying directly from Super 73 usually means you get their warranty and customer support. Buying from Amazon or a third-party retailer sometimes means lower prices but also means dealing with that retailer if something goes wrong in the first 30 days.

Super 73's standard warranty covers the frame and motor for one year and the battery for two years. That means if the motor fails in month six, they'll replace it. If the battery stops holding a charge in year one, they'll replace it. The warranty does not cover normal wear like brake pads, tires, or damage from crashes or water damage. Read the specific warranty terms on their website before you buy, because coverage details vary by model and retailer.

Real costs of owning a Super 73 for a year

If you buy an S2 for $1,400, add a helmet ($150), a lock ($75), and lights ($50), you're at $1,675 before you ride it once. In year one, budget another $150 to $200 for maintenance and repairs—brake adjustments, tire patches, maybe a new tire. Electricity to charge the battery costs almost nothing, maybe $20 to $40 per year depending on your local power rates. So a realistic first-year cost is around $1,850 to $1,900.

In year two and beyond, you're mainly paying for maintenance and repairs. If you ride regularly, expect $150 to $250 per year. If you ride casually a few times a month, you might spend only $50 to $100 per year. The battery will eventually need replacement—that's a $400 to $800 hit whenever it happens, typically after 3 to 5 years of regular use.

Whether a Super 73 makes sense for your situation

A Super 73 is a good choice if you want a fun, casual bike for short trips around your neighborhood or city, and you like the retro moped look. It's not a good choice if you need to commute 10+ miles regularly, climb hills, or ride in rain and snow. The weight and motor design make them slow in traffic and tiring to pedal if the battery dies. They're also not theft-proof—the moped style makes them a target, so you need a serious lock and somewhere find to store it.

If you're mainly interested in getting around town without a car, a lighter electric bike or a regular bike with a cargo rack might serve you better and cost less. If you want the experience of riding something that feels like a vintage moped and you have the budget, Super 73 delivers that. Just go in knowing what you're paying for: a lifestyle choice, not a transportation solution that will save you money compared to other options.

Frequently Asked Questions

Can I ride a Super 73 without pedaling?

No. The motor only works when you're pedaling. If you stop pedaling, the motor stops assisting. This is by design and by federal law—bikes that work without pedaling are classified as mopeds and require registration and a license in most states.

How long does the battery last before it needs replacing?

Most Super 73 batteries last 3 to 5 years with regular use before they stop holding a full charge. The warranty covers the battery for two years. After that, replacement costs $400 to $800 depending on the model. Lifespan depends on how often you charge, temperature, and how hard you use the motor.

Is a Super 73 legal to ride on bike paths?

It depends on your state and local laws. Most states allow electric bikes under 750 watts on bike paths if they're pedal-information only, which Super 73 bikes are. But some cities restrict them or require registration. Check your local bike path rules and your city's electric bike regulations before you buy.

What's the difference between the S2, RX, and Z models?

The S2 has a smaller battery and motor, the RX has a mid-size battery and upgraded components, and the Z has the largest battery and premium features like hydraulic brakes. The S2 is cheapest and lightest. The Z is most expensive and has the longest range. The RX is the middle ground.

Do I need insurance for a Super 73?

Most homeowners or renters insurance policies don't cover bikes. You can add a rider to your policy or buy separate bike insurance, which typically costs $100 to $300 per year depending on the bike's value and your location. It's worth doing if you're leaving the bike outside or commuting with it regularly.
