Super73 and Juiced make e-bikes that blur the line between bicycle and electric motorcycle. Both the RX and HyperScrambler 2 look like 1970s scrambler motorcycles, deliver real-world performance well above typical Class 2 bikes, and attract buyers who want a statement vehicle that can hit legal limits quickly and cruise there comfortably. The HyperScrambler 2 is the more powerful machine; the Super73 RX is the better polished product at nearly the same price.

Specs Comparison

Motor Power and Real-World Speed

The Juiced HyperScrambler 2 uses a 1,000W nominal rear hub motor with a claimed 1,800W peak output. In Class 3 mode (pedal-assist to 28mph), it's genuinely quick — 0-20mph feel is closer to a lightweight electric motorcycle than a traditional e-bike. Switch to the unlocked mode that Juiced enables in settings, and the bike can reach 34-38mph on flat ground, which firmly places it in the moped/low-speed motorcycle category legally in most states.

The Super73 RX uses a 1,000W nominal motor as well, but Bosch and Super73's own tests put peak output closer to 1,400-1,500W. In Class 2 configuration (throttle and pedal-assist to 20mph), the RX is smooth and responsive. Super73's proprietary controller is tuned for linear, predictable power delivery — it doesn't lunge at full throttle the way some high-power hub motors do.

Both bikes are legally classified as Class 2 e-bikes out of the box in most US states — throttle to 20mph, pedal-assist to 20mph. The HyperScrambler 2's higher-mode capabilities push it into moped territory legally, requiring registration and possibly a license in many states. The Super73 RX stays in e-bike territory more cleanly, though some riders use aftermarket controllers to push it above class limits at their own legal and safety risk.

Battery and Range

Juiced equips the HyperScrambler 2 with a 1,045Wh battery — genuinely large for a consumer e-bike and one of the biggest available outside of purpose-built cargo or long-range commuter platforms. At Class 2 speeds with moderate pedaling, real-world range sits at 60-80 miles. At higher-mode full-throttle operation, expect 30-45 miles. The battery is integrated into the frame's downtube and cannot be removed without tools.

The Super73 RX uses a 960Wh battery in its current configuration. Real-world range is 40-75 miles depending heavily on terrain, rider weight, and assist level. Like the HyperScrambler, the RX battery is frame-integrated and non-removable for home charging — you charge via the bike's onboard port.

Neither battery is removable, which means apartment dwellers need to bring the whole bike inside to charge, run a long extension cord, or use a public charging point. Both charge from a standard 120V outlet with the included charger; the HyperScrambler 2's larger battery takes approximately 7-8 hours from empty. Super73 offers an optional fast charger that cuts RX charge time to around 4 hours.

Build Quality and Component Specification

Super73's RX is built in a dedicated facility with tighter quality control than what Juiced has historically delivered. The RX's welding, paint finish, and component fit are noticeably more consistent. The RX uses front suspension with 80mm of travel, high-quality Kenda tires, and a hydraulic disc brake setup that inspires real confidence at speeds above 20mph.

The HyperScrambler 2 uses mechanical disc brakes — a significant concern at a bike that can legitimately reach 30+ mph in higher modes. Juiced has faced criticism from owners for inconsistent quality control on early production runs, and their customer service reputation doesn't match Super73's. Parts availability for the HyperScrambler 2 is improving but still less robust than Super73's dealer and parts network.

Super73's proprietary display and control system has improved significantly with recent firmware. The RX display shows speed, battery level, and assist mode clearly. Juiced's display is functional but less refined in software and layout.

Legal Classification and Practical Use

The Super73 RX in stock Class 2 configuration can be ridden on bike paths and lanes in most US states without registration, license, or insurance. Its 26x4.0 fat tires and low-slung geometry feel stable and deliberate — the bike communicates its weight and momentum honestly.

The HyperScrambler 2 in higher modes occupies a legal gray area. At 34-38mph, it exceeds the definition of a Class 3 e-bike in every US state and requires moped or motorcycle registration in most jurisdictions. Juiced sells it as an e-bike, but using its full capabilities on public roads without registration is a legal exposure. Buyers should research their state's specific requirements.

For practical urban commuting at legal Class 2 limits: the Super73 RX is the more sensible choice — better-braked, better-finished, better-supported. For a buyer who wants maximum performance and lives in a context where the higher-mode operation is practical (private property, track, or a tolerant rural jurisdiction): the HyperScrambler's extra power and battery capacity are real.

Best For

• Super73 RX Riders who want the best-finished, safest, most legally clean moped-style e-bike at this price point
• Juiced HyperScrambler 2 Riders who want maximum power and battery and are prepared to navigate the legal considerations of higher-mode use
