Super73 Z Miami E-Bike Review

The Z Miami is Super73's entry-level model, designed with the same low, retro frame as the rest of the lineup but with a simpler spec sheet to match a lower price.

This e-Bike uses a cadence sensor, so the motor responds as soon as the pedals turn instead of amplifying how hard you're pedaling. It has a thumb throttle on the right side that works independently of pedaling, but it can act a bit like an on-off switch, so gradual acceleration takes some getting used to.

The single-speed drivetrain keeps things simple, but the low, retro seating position isn't built for efficient pedaling. It's pretty relaxed, so some riders might find that their knees don't reach full extension, which makes pedaling any distance more awkward than it should be.

The SE's front suspension and hydraulic brakes make a noticeable difference on rough pavement compared to the Core's rigid frame and mechanical brakes. The difference isn't that dramatic if you're planning to ride mostly paved streets, but on broken pavement, it's significant.

The Super73 app connects over Bluetooth for turn-by-turn navigation on the bike's small display, so you don't need a phone mount to get directions while riding.

The rear hub motor is rated at 500W nominal on current Core and SE models, enough for flat urban riding and moderate hills without much strain. It's a hub motor, not a mid-drive system, so it's not as efficient on steep or sustained climbs.

The 480Wh battery is UL 2271 compliant and charges in about 5 hours. Super73 claims up to 35 miles of range, but actual distance depends on factors like rider weight, terrain, and throttle use. Since this battery is smaller, keeping it properly maintained and checking the drivetrain and brakes regularly is important for reliable performance.

The Core has no suspension at all. Every bump and pothole comes through the frame directly, a fair trade-off for the lower price.

The throttle isn't gradual. Some riders have found it delivers full power immediately instead of ramping up, which takes some adjustment if you're used to a more progressive throttle.

Pedaling comfortably is harder than it looks. The compact seating position limits leg extension, so riders who plan to pedal a lot instead of using the throttle should try one before buying.

Spec sheets have changed from model year to model year. Earlier Z Miami units used a more powerful motor and a larger battery than the current Core and SE, so it's worth checking a used listing's exact specs before assuming.

The Super73 S2 (an Upway best-seller!) costs more but adds a larger battery and more motor power, making it worth the step up if the Z Miami's range and output feel limiting.

The Super73 RX sits at the top of the lineup, with full suspension and considerably more performance, making it a better fit for riders who've outgrown the entry-level bikes.

An entry-level bike like the Z Miami is a common way into the Super73 lineup, and buying pre-owned makes that entry point even more affordable. Upway puts every listing through 50 inspection points before it's cleared for sale, and any battery under 80% capacity gets swapped out ahead of time. A one-year warranty covers the frame, motor, and electrical system, plus 14 days to make sure it's the right fit once it arrives.
