Super73 Z Miami: specs and AEB Score

Not ridden by Will yet. I haven’t ridden, filmed or tested the Super73 Z Miami. This page is a research profile, not a review. Every number on it comes from Super73’s own product pages, warranty and return policy, the U.S. Consumer Product Safety Commission (CPSC), or the pages of rival bikes, all linked at the bottom. Where I compare it with a moped-style bike I have filmed, the riding notes are about that other bike, not this one. All prices and checks on this page are as of Oct 26, 2026.

The Super73 Z Miami is a small, low, fat-tired bike in a minibike style, and Super73 sells it on design as much as on numbers. Below is what Super73 promises, what it leaves out, and how it stacks up against cheaper and pricier options, so you can decide whether the look is worth the trade-offs.

Should you buy one?

On paper, the Z Miami Core is a short-range, throttle-first neighborhood cruiser for shorter riders, sold at a premium for the brand and the design. For $2,195, Super73 lists a 500W nominal motor, a 480Wh battery, a 20 mph top speed in Class 2, a single-speed drivetrain, 4-inch VEE Trooper tires, mechanical Tektro disc brakes, a rigid aluminum frame with no suspension, LED lights and a 59 lb weight. Super73 calls it the Legacy Series version, with a new powertrain it says gives 20% more acceleration than its previous one.

The trade-offs on paper:

• It’s small on purpose. The recommended rider height is 4’6” to 5’11” with a 28-inch seat. Riders over six feet are outside Super73’s own range.
• No suspension and mechanical brakes on the Core. For suspension and hydraulic brakes, you have to step up to the $2,695 SE, which adds a suspension fork and Super73’s own hydraulic brakes.
• The range is modest. Super73 rates it at 25 to 35 miles, or 25+ miles at 20 mph on throttle only.
• One gear. It’s a single speed, so pedaling is a backup, not a workout plan.
• Returns are strict and costly. No returns once the bike is opened or used. An unopened return costs a 15% restocking fee.
• The warranty is short on the frame. One year on the frame and fork, two years or 500 cycles on the battery and electrical parts.

Who it fits on paper: riders roughly 4’6” to 5’11” who want a fun, eye-catching bike for short trips around town, the beach path or campus, and who care about the look as much as the spec sheet.

Who should look elsewhere: tall riders, anyone with a long commute, riders who need gears for hills, and shoppers who want suspension and hydraulic brakes without paying $2,695.

Legal check before you buy: Super73 sells the Z Miami as a Class 2 bike with a 20 mph top speed and a thumb throttle. It also says customers who download and pair the Super73 app after January 1, 2025 can’t access any mode other than the Class 2 mode the bike is sold in. That’s good news if you want a bike that stays legal by default. It’s also an honest warning if you’ve seen older videos of Super73 bikes in faster “off-road” modes: on a new bike paired with the app today, Super73 says those modes aren’t available. Super73 also says the bike is for riders 16 and older. Some states and cities set their own age rules for e-bikes, so check yours on my e-bike laws hub.

Pros and cons (from the specs and sources)

Pros

• The minibike design, which is the main reason to buy it
• 59 lb is light for a moped-style bike; the MZFT is 85 lb
• 325 lb rider limit, high for a bike this small
• Fits shorter riders, down to 4’6” by Super73’s range
• Class 2 by default, with app access limited to that mode for new pairings
• UL 2271 compliant battery
• Simple single-speed drivetrain with little to adjust
• Super73 says assembly takes about 15 minutes

Cons

• No suspension on the Core
• Mechanical, not hydraulic, brakes on the Core
• 480Wh battery and 25 to 35 miles of range
• Single speed, so steep hills fall on the motor
• No horn
• Frame warranty is only 1 year
• No returns once opened; 15% restocking even when unopened
• An earlier model year of the Z Miami SE was recalled for a brake problem
• I can’t speak to the ride, because I haven’t ridden it

What the Z Miami actually is

It helps to be clear about the category before comparing numbers. The Z Miami isn’t a commuter in the way a Velotric or Ride1Up commuter is. It has no rack listed, no fenders listed, one gear and a short wheelbase. It’s closer to a minibike with pedals: low to the ground, with fat tires on small wheels and a long, flat seat. Super73 calls it “the cooler compact cruiser” on its SE page and describes the Core as “our compact neighborhood explorer.”

That framing matters because it changes what “good value” means. If you judge it as transportation, $2,195 buys less battery, less range and fewer gears than many commuter bikes at that price. If you judge it as a fun, short-hop bike with a strong brand and a design people recognize, the question becomes whether you’re paying a fair premium for that design, and whether the parts underneath are good enough that the fun lasts.

There’s another reason the category matters: who it’s built for. The 4’6” to 5’11” height range and the 28-inch seat mean many teenagers (16 and up, per Super73) and shorter adults can put their feet flat at a stop. That’s a real advantage. Plenty of moped-style e-bikes are sized for a 5’6” to 6’2” adult and feel tall and heavy to a small rider. The Z Miami goes the other way.

The Legacy Series update

Super73 now sells the Z Miami as part of what it calls the Legacy Series. On its Legacy Series page, it says it “crafted a lineup that meets every rider’s needs” with “an entirely new powertrain,” updated controllers, “improved battery efficiency” and UL 2271 compliant batteries. The headline numbers it gives are acceleration claims: up to 30% more on the SE, and 20% more on the Core, each compared with Super73’s previous powertrains.

Two things to know about those claims:

1. They’re relative, not absolute. Super73 doesn’t publish a 0 to 20 mph time, a torque figure or a peak power figure for the Core. So “20% more acceleration” tells you the new bike pulls harder than the old one, but not how hard that is.
2. Super73 qualifies them. Its fine print says acceleration gains “may vary depending on rider weight, riding terrain, battery state of charge, weather, and other environmental factors.”

The part that’s easier to verify is the battery certification. Super73 lists the 480Wh pack as UL 2271 compliant. UL 2271 is the safety standard for e-bike batteries, and it’s increasingly required by cities and landlords. It says nothing about range or quality, but it is a safety baseline.

Motor, throttle and the “Class 2 only” app rule

Super73 lists a 500W nominal motor and a thumb throttle. It doesn’t list a torque figure or a peak wattage. The spec table also doesn’t describe pedal-assist levels for the Core, so I’ve marked that “not listed” rather than guess.

500W nominal is under the 750W federal limit for a low-speed electric bicycle. With a single gear, the motor is doing nearly all the work up hills, which is why the acceleration claim matters more on this bike than on a geared commuter. Without a torque number, it’s hard to say how it’ll handle a long, steep climb with a heavier rider. If you live somewhere hilly, I’d treat that as the biggest unknown on the spec sheet.

The app rule is the more important detail. Super73 says that customers who download and pair the Super73 app after January 1, 2025 “will not have the ability to access modes other than the Class 2 mode in which the product is sold.” In plain terms: on a new Z Miami, Super73 is saying it stays a 20 mph throttle bike. If you were drawn to Super73 by older clips of riders unlocking faster modes, don’t buy this bike expecting that.

From a legal point of view, that’s a plus. A Class 2 bike, under the common three-class system, has a throttle and a 20 mph motor cutoff. That’s the class most places treat like a regular bicycle, though rules on bike paths and age vary.

Battery, range and charging

The battery is 48V 10Ah, or 480Wh, and Super73 lists a five-hour charge. Super73 rates the range at 25 to 35 miles, and specifically says 25+ miles at 20 mph using throttle only in Class 2.

That throttle-only figure is the useful one. Most riders on a single-speed moped-style bike will lean on the throttle, and Super73 is telling you what to expect in that case. Super73 also says range depends on “rider weight, speed, temperature, wind, tire pressure, terrain, incline, etc.”

What that means in practice. Twenty-five miles covers a round trip of about 12 miles each way, or a week of short campus or neighborhood trips. It’s not enough for a long daily commute without charging at work. Fat 4-inch tires and an upright, un-aerodynamic position use more energy than a narrow-tire commuter, so the throttle-only number is the one I’d plan around.

For context, Velotric’s Discover 3 commuter lists 730Wh for $1,999, and Ride1Up’s Prodigy V2 ECO lists 504Wh for $1,295. Neither is the same kind of bike, but the comparison shows that the Z Miami’s price is not about battery size.

Brakes and the recall on the earlier SE

The Core’s brakes. Super73 lists Tektro two-piston mechanical disc brakes on the Core. Mechanical disc brakes use a cable, not hydraulic fluid. They’re simpler to adjust at home, but they generally need more hand force and more frequent adjustment than hydraulics as pads wear. One reviewer on Super73’s own Core page wrote that the brakes “needed to be calibrated” when the bike arrived. That’s one owner’s report, not a test, but I’d check the brakes before the first ride.

The SE’s brakes. The $2,695 Z Miami SE uses Super73-branded two-piston hydraulic brakes.

The recall. In February 2025, Super73 and the CPSC recalled about 1,400 model year 2024 Z Miami SE and Z Adventure Core e-bikes sold from April to September 2024 for about $2,300 to $2,500. The CPSC says the brake caliper retaining pin “can loosen,” which can cause brake failure. Super73 had 21 reports and one minor injury. The fix was a free replacement pin and up to $50 toward installation. The recalled model numbers were 900-00288, 900-00309 and 900-00313 (Z Miami SE) and 900-00308 (Z Adventure Core).

That recall was for an earlier model year, not the current Core. I found no recall listed for the current Legacy Series Core in the CPSC database on Oct 26, 2026. If you’re buying a used Z Miami SE, check the model number and ask the seller whether the recall fix was done. Super73’s recall contacts are 888-841-3584 and [email protected].

Frame, tires and ride comfort

The Core has an aluminum frame with no suspension front or rear. Super73 lists it simply as “Rigid.” All the cushioning comes from the tires: VEE Trooper, 4 inches wide, front and rear, on 20-inch wheels with 20 x 4.5-inch tubes.

Fat tires at lower pressure do soak up a lot of small bumps, cracks and gravel. They don’t do much for big hits like curb drops or potholes at speed, which is where a suspension fork helps. One SE owner on Super73’s page wrote that the bike “loses power when going off a curb/big bumps.” That’s one review of the SE, not a test result, and I don’t know the cause. But it’s a reminder that this is a street and hard-packed-path bike, not a jump bike.

The SE adds an adjustable front suspension fork (the rear stays rigid) and MAXXIS SuperSucker tires, 4.5 inches in front and 5 inches in back. If you know your routes are rough, the SE’s extra $500 buys the two parts I’d most want on this kind of bike: a fork and hydraulic brakes.

Fit, weight and size

Fit. Super73 recommends the Z Miami for riders 4’6” to 5’11”, with a 28-inch seat height. The seat is long and flat, moped style, so riders can shift fore and aft a bit, but there’s no listed seat height adjustment range. If you’re near the top of that range, I’d want to sit on one first.

Weight. 59 lb is light next to the other moped-style bikes on this page. Super73’s own MZFT lists 85 lb. The Fahrbike Roadster 73 I filmed lists 83 lb.

Size. At 64 inches long and 25 inches wide, the Z Miami is compact. That helps in a garage, an apartment hallway or a car with a hitch rack, though 4-inch tires won’t fit every bike rack’s wheel trays. Check yours.

Load. Super73 lists a 325 lb rider weight limit. That’s high for a small bike and makes the Z Miami more practical for adults than its size suggests. Super73 doesn’t list a rack or a rack rating for the Core.

What’s included, and what isn’t

Super73’s Core spec table lists LED head and tail lights. It lists “Horn: NO.” It doesn’t list fenders, a rack, a kickstand or a display model, so I’m not assuming any of them. Before buying, look at the photos on the product page and, if it matters, ask Super73 directly what’s in the box.

One owner review on the Core page says, “Don’t love the push throttle or the fact that there is no key ignition.” That matches the spec table’s thumb throttle. On the key, the spec table doesn’t say either way. If a key switch or a removable, lockable battery matters to you for theft or charging indoors, confirm it with Super73 before ordering.

Warranty, returns and support

Warranty. Super73’s Z-series limited warranty covers the frame and fork for 1 year from delivery, and the battery and electrical parts (motor, controller, display and sensors) for 2 years or 500 charge cycles, whichever comes first. For the battery, Super73 defines a defect as falling below 70% capacity within that period. The warranty is for the original purchaser only, isn’t transferable, and requires registration and a receipt.

A 1-year frame warranty is short. Velotric gives 5 years on the Discover 3 frame. Specialized gives a lifetime frame warranty to registered original owners. Ride1Up gives 1 year overall. So Super73 is at the low end for the frame, and in the middle for electrical parts.

Returns. This is the part I’d read twice. Super73’s returns and cancellations policy says:

• You can cancel within 24 hours of ordering.
• If the bike has already shipped and you recall or refuse it, there’s a 15% restocking fee and shipping isn’t refunded.
• Used or opened bikes can’t be returned.
• Unopened bikes can be returned with photo proof within 15 days of delivery, with a 15% restocking fee.
• Batteries are final sale.
• Bikes need a signature on delivery, and missed deliveries can carry storage fees.

On a $2,195 bike, 15% is about $329, even if you never open the box. Once you open it, you own it. That makes sitting on one in person, or a long look at the size chart, more important than it is with brands that take back a ridden bike.

Shipping. Super73 ships to the 48 contiguous states and Hawaii. It says Hawaii orders take 4 to 6 weeks and are excluded from free shipping promotions, and final shipping costs are calculated at checkout.

How it compares

The Z Miami column is spec-only. The Fahrbike Roadster 73 is the moped-style bike I’ve filmed; its riding notes are about that bike.

Against the Z Miami SE. For $500 more as of Oct 26, 2026, the SE adds an adjustable fork, hydraulic brakes and wider MAXXIS tires, plus a stronger acceleration claim (up to 30% versus 20%, each compared with Super73’s previous powertrain). If you can stretch to it, those are the two upgrades I’d want most on a bike that relies on its tires for comfort and on its brakes at 20 mph. The SE is also the trim that had the February 2025 brake recall on an earlier model year; the current SE isn’t on that recall list.

Against the MZFT. The MZFT is $200 less as of Oct 26, 2026, and has hydraulic brakes, a horn and lockable storage. But its single-battery range is 15 to 20 miles, it weighs 85 lb, and its rider limit is 250 lb. The Z Miami goes farther on one battery, is 26 lb lighter and carries 75 lb more rider. For most adults, the Z Miami fits better.

Against the Fahrbike Roadster 73. This is the comparison that shows what you’re paying for. When I filmed the Roadster 73, it had a 750W motor, a 720Wh battery, eight gears, front and rear suspension and hydraulic brakes, and I got 42 miles at about 200 lb in winter. It’s also 83 lb and sized for riders 5’3” to 6’4”. On paper, the Roadster gives you more of almost everything for less money, but it’s sold out in every color as of Oct 26, 2026, and it’s a heavier, taller bike. The Z Miami’s case is size, weight, brand, design and a Class 2 setup that stays put.

Who it’s for, on paper

• Shorter riders and older teens (16+) who want a bike they can flat-foot at a stop.
• Short-trip riders doing campus, beach, downtown or neighborhood runs under about 12 miles each way.
• Riders who want the Super73 look and are willing to pay for the brand.
• Families who want a Class 2 bike that stays Class 2, given Super73’s app rule for new pairings.

Not a great fit for: riders over 6 feet, hilly long-distance commuters, anyone wanting gears, or anyone who needs a lenient return policy.

What I’d check before buying

1. Your height and inseam against Super73’s 4’6” to 5’11” range and 28-inch seat height. Sit on one in person if you can.
2. Core or SE. Price out whether the SE’s fork and hydraulic brakes are worth $500 for your roads.
3. Your longest regular trip, against 25 miles on throttle at 20 mph.
4. Your hills. One gear and no published torque figure means the motor has to do it all.
5. The return policy. Once opened, no return. Even unopened, 15% restocking.
6. What’s in the box. Ask about fenders, a rack, a kickstand, a key and how the battery comes out, since the spec table doesn’t list them.
7. Your local age and path rules, on my e-bike laws hub.
8. If buying used, the model number against CPSC recall 25149.

FAQ

No. This page is built from Super73’s official pages and policies, the CPSC and rival bikes’ official pages, all linked below. The only bike in the comparison I’ve filmed is the Fahrbike Roadster 73.

Is the Z Miami street legal?

Super73 sells it as a Class 2 bike with a 20 mph top speed and a throttle, which fits the common three-class system. It says new app pairings after January 1, 2025 can only use that Class 2 mode. Age and path rules vary by state and city, so check my laws hub.

How far does it go on a charge?

Super73 rates it at 25 to 35 miles, and 25+ miles at 20 mph on throttle only.

How much does it weigh?

59 lb, per Super73.

Can tall riders use it?

Super73 recommends it for 4’6” to 5’11”. Riders taller than that are outside Super73’s range.

What’s the difference between the Core and the SE?

The SE ($2,695) adds an adjustable front fork, Super73 hydraulic brakes and wider MAXXIS tires, in Astro Orange or Blackout. The Core ($2,195) is rigid, with Tektro mechanical brakes and 4-inch VEE tires, in Metallic Aluminum.

Was the Z Miami recalled?

The model year 2024 Z Miami SE was recalled in February 2025 for brake caliper pins that can loosen (CPSC 25149). I found no recall listed for the current Core in the CPSC database on Oct 26, 2026.

Can I return it?

Only unopened, within 15 days of delivery with photo proof, and with a 15% restocking fee. Opened or used bikes can’t be returned.
