Super73 Z Miami Core: Bikes and Accessories Roundup

Picking the right accessories and bikes for a Super73 build means knowing which products actually fit the platform, and which ones are generic listings that won’t hold up after a season of real use. The moto-style frame geometry, the fat tires, the specific handlebar diameter on models like the K1D and RX: these details matter when you’re buying a cover, a phone mount, or choosing which model to ride in the first place.

This roundup covers the core Super73 ecosystem, two flagship bikes and four accessories worth owning. Whether you’re new to the platform or adding gear to a bike you already have, here’s what holds up.

Top Picks

Bike Cover for Super73 K1D R Adventure RX, XL

The Bike Cover for Super73 K1D R Adventure RX, XL is the largest size option in this cover lineup, designed to fit the full footprint of Super73’s bigger frames. Verified buyers consistently note it fits the RX and Adventure variants without excess bunching at the front or riding up over the rear tire, which is the failure mode you see with generic motorcycle covers on fat-tire bikes.

The water-repellent treatment holds up through sustained rain based on owner reports, and the UV-resistant material is the feature that justifies storing this outdoors long-term rather than just using it in a garage. The lock-hole design is a practical detail: you can run a cable lock through the bike and grommet without removing the cover, which matters if you’re leaving the bike outside overnight.

For riders with the RX, Adventure, or any of the larger-frame Super73 builds, the XL is the right starting point. If you’re running a K1D or S-series, size down before purchasing.

Super73-S2 Urban Electric Bike

The Super73-S2 Urban Electric Bike is the entry point into the Super73 lineup and the model that established the brand’s visual identity, low-slung moto silhouette, swept-back handlebars, fat tires on a rigid fork. No front suspension means it’s optimized for pavement and packed gravel, not technical terrain. That’s not a compromise for the rider it’s built for.

Owner reports and community field data from r/Super73 and various enthusiast forums consistently describe the S2 as a composed urban commuter. The torque delivery is smooth enough for stop-and-go traffic, and the step-through geometry on some variants makes daily riding practical. The rigid fork actually benefits this use case, less maintenance, more predictable handling on smooth surfaces, and a cleaner look.

The S2 makes the most sense for riders who want the Super73 aesthetic and platform without paying for suspension components they won’t use on pavement. It’s a strong foundation: buy the bike, add the cover and phone mount from this list, and you have a complete, practical urban setup.

Super73-RX Moto-Style Electric Bike

The Super73-RX is the flagship. Dual suspension, Class 3 capability, a motor spec built for actual climbing load, this is the bike for riders who want to leave pavement. Based on verified buyer reports and extensive community coverage on Pinkbike and MTBR, the RX’s front and rear suspension setup transforms the platform from urban commuter to genuine adventure bike.

The geometry is more aggressive than the S2, longer wheelbase, more trail, which pays off on loose surfaces and technical terrain but makes it feel planted rather than nimble in tight urban environments. Riders who split time between city streets and dirt roads report this as a non-issue once they’re used to it.

Class 3 certification means the RX can be configured to run at higher assisted speeds where legally permitted, which changes the use case entirely for riders covering longer distances or open roads. The motor torque characteristics under load are what field reports consistently call out as the differentiator from lower-spec builds in this category.

The RX is a dealer and direct-to-consumer product. Check Super73’s site for current availability and regional dealer listings.

Bike Cover for Super73 K1D R Adventure RX, Medium

The Bike Cover for Super73 K1D R Adventure RX, Medium fits the smaller end of the Super73 model range, primarily the K1D and S-series. The same water-repellent and UV-resistant construction applies across all sizes in this lineup, so the trade-off here is purely fit. Buy the wrong size and the cover either gaps at the rear or cinches too tight at the handlebars, both of which reduce protection and accelerate wear on the cover material itself.

Verified buyers running the K1D report the medium fits cleanly without needing adjustment straps. The lock-hole placement on this size aligns with the K1D’s typical locking geometry, which is the detail that separates a cover designed for this platform from a generic option.

Bike Cover for Super73 K1D R Adventure RX, Large

The Bike Cover for Super73 K1D R Adventure RX, Large occupies the middle ground between the medium and XL, the right fit for the Adventure and standard RX without the excess material that sometimes causes wind lift issues with oversized covers on lighter builds.

For riders who’ve had trouble finding a cover that accounts for Super73’s tall handlebar rise and wide handguard spread, the large tends to clear those areas cleanly based on community fit reports. The seam construction on this size follows the same pattern as the rest of the lineup. All-weather protection means it’s rated for both rain and UV, which matters more than it seems if the bike lives outside between rides.

Motorcycle Phone Mount for Super73-K1D 2023, 2026

The Motorcycle Phone Mount for Super73-K1D is listed specifically for the K1D’s handlebar diameter, which is not universal across the Super73 lineup, and that specificity matters. Generic bar mounts sized for standard motorcycles often don’t clamp securely on Super73’s bars, leading to vibration-induced movement on anything rougher than glass pavement.

The aluminum alloy construction handles the Super73’s vibration profile better than plastic-bodied alternatives. Verified buyers report the 360° rotation locks down firmly once set, which is the function that fails on cheaper mounts after a few weeks of regular riding. The clamp mechanism is tool-accessible, not tool-required, which is practical for riders who adjust phone orientation seasonally or switch between phones.

Worth noting: this mount is listed for 2023, 2026 K1D specifically. Riders running an RX or S2 should verify handlebar diameter compatibility before purchasing, the fit on non-K1D models is not guaranteed by the product listing.

Buying Guide

Understanding the Super73 Model Range

The Super73 lineup splits into two broad categories: rigid urban bikes (S1, S2, ZX, Z Miami) and suspension-equipped adventure builds (RX, Adventure, K1D). These are not interchangeable use cases. Accessories like covers and mounts are often sized and designed for specific frame geometries, so knowing which model you’re running, or planning to buy, is the first decision that gates everything else.

The S2 and Z-series bikes have a more compact footprint than the RX platform. This affects cover sizing, handlebar diameter for mount compatibility, and even which aftermarket parts fit without modification.

Choosing the Right Cover Size

Cover fit on Super73 bikes is more precise than it is on standard bicycles because of the fat tire width, elevated handlebar rise, and moto-style fender geometry. A cover that fits a standard commuter e-bike often gaps at the rear wheel or pulls tight across the cockpit on a Super73 frame.

Use the model-specific guidance: medium for K1D and S-series, large for standard RX and Adventure, XL for extended-frame builds and bikes with aftermarket handguards or handlebar risers.

If you’ve added bar ends, phone mounts, or mirrors that increase handlebar width, size up one. The lock-hole design works across all three sizes, don’t let that detail influence your size selection.

Phone Mount Compatibility Across the Platform

Handlebar diameter varies across the Super73 model range, and this is the specification that determines whether a phone mount will clamp securely or slip under vibration. The mount listed here is specified for the K1D’s bar diameter. RX and S2 riders should measure their bars before purchasing any mount, the diameter difference is small enough that it’s easy to miss in a product listing but significant enough to affect clamp security.

Aluminum alloy bodies are the right call for this platform. Super73’s fat tires absorb road vibration well, but the motor feedback and off-road use cases the RX and Adventure bikes support generate enough handlebar movement to crack plastic cradles over time. Metal construction with a properly torqued clamp is the baseline for any accessory that needs to stay in place under load.

Matching Bike Choice to Riding Context

The choice between the S2 and RX is a decision about terrain and intent, not about budget tiers alone. The S2 is a precision instrument for urban riding, its rigid fork, smooth torque delivery, and compact geometry make it well-suited for daily commutes, bike lanes, and mixed-use paths. Adding suspension components the S2 doesn’t have won’t make it a better urban bike; it would just add weight and maintenance.

The RX is the right answer when the riding context includes unpaved surfaces, longer distances, or the need for Class 3 speed capability. Verified buyer reports from riders who commute during the week and ride trails on weekends consistently describe the RX as more capable across both contexts than any rigid-fork alternative at this price band. The dual-suspension system is not a luxury on a bike this heavy, it’s load management.

Accessories as a System

The most common Super73 accessory mistake is buying for aesthetics rather than function. A cover that doesn’t account for the handlebar width or fender geometry leaves the motor housing and battery exposed during rain. A phone mount that isn’t rated for the specific handlebar diameter becomes a navigation liability on anything but flat pavement.

The accessories in this roundup are selected because they’re specified for Super73’s actual dimensions, not because they’re the most-marketed options. Cross-reference your model and year against each product’s compatibility list before purchasing. The Super73 platform has enough model variation across 2020, 2026 that what fits a 2021 RX may not fit a 2024 K1D without adjustment.

Frequently Asked Questions

What’s the difference between the Super73-S2 and the Super73-RX?

The S2 is a rigid-fork urban commuter, no suspension, optimized for pavement, lighter and more maneuverable in city environments. The RX has dual suspension, a Class 3-capable drivetrain, and the geometry to handle unpaved surfaces and longer-distance riding. For daily urban commuting on smooth roads, the S2 is the more practical choice. For riders who mix terrain or want the full performance envelope of the Super73 platform, the RX is the correct bike.

Which cover size should I buy for my Super73?

Size selection depends on your specific model and configuration. The medium fits K1D and standard S-series bikes cleanly. The large is the right fit for the standard RX and Adventure without excess material. The XL handles extended-frame builds and bikes with aftermarket handlebar accessories that increase the cockpit’s overall width.

Is the phone mount compatible with all Super73 models?

The Motorcycle Phone Mount for Super73-K1D is listed specifically for the 2023, 2026 K1D’s handlebar diameter. Compatibility with RX and S2 models is not guaranteed by the product listing. Measure your handlebar diameter before purchasing if you’re running a different model, the difference between a secure clamp and a loose one on this platform is a matter of millimeters.

Can I leave my Super73 outside year-round with one of these covers?

The water-repellent and UV-resistant construction on the covers in this roundup is rated for all-weather outdoor storage. Owner reports from buyers in high-rain regions consistently describe the covers holding up through full seasons without seam failure. UV exposure is the longer-term risk for any outdoor-stored e-bike, battery and motor housing degrade faster with sustained direct sunlight. The UV treatment on these covers addresses that directly.

Where can I buy the Super73-S2 and RX if they’re not on Amazon?

Both the S2 and RX are sold through Super73’s direct-to-consumer channel at super73.com and through authorized regional dealers. Super73 does not sell these models through Amazon. For current pricing, availability, and regional dealer locations, the Super73 site is the correct starting point. Accessories like covers and phone mounts for the platform are available through Amazon, see the product links throughout this roundup.
