Introducing the Revolution X9

Quick Answer:

The Revolution X9 is a limited-production e-bike from Hi Power Cycles (HPC), built around a 9000W Crystalyte gearless hub motor and a 78V USA-made battery rated for up to 100 miles of range. It’s capable of 65+ MPH, and only 30 units are being produced — each individually numbered, with custom color options included at no extra charge.

This week’s “Bicycle of the Week” is the Revolution X9, a high-performance e-bike from Hi Power Cycles (HPC) and the successor to HPC’s Revolution XX, which sold out at 20 units. The X9 expands the run slightly to 30 units, each individually numbered. This isn’t a casual commuter bike — it’s a hand-built, limited-production machine aimed at riders who want serious power. The headline numbers: a 9000W Crystalyte gearless hub motor, a Schlumpf High Speed Drive for high-cadence pedaling, a 78V USA-made battery good for up to 100 miles, and a claimed top speed north of 65 MPH.

The Revolution X9, the fastest ebike on the market, is this week’s “Bicycle of the Week.” The X9 is not your average electric bike—it’s a high-performance e-bike built for those who demand speed and precision. As the successor to the legendary XX, this top speed electric bike pushes boundaries even further. Imagine tearing through the streets at over 65 MPH, powered by a near-silent 9000W motor that responds to your every command.

With only 30 units ever made, the X9 isn’t just an e-bike; it’s an exclusive e-bike experience. Every detail, from its robust moto-style tires to its custom-tuned performance, screams power and luxury. The Revolution X9 isn’t just fast—it’s the future of e-biking, and it’s ready to take you there.

From the Revolution XX to the X9

HPC’s previous model, the Revolution XX, sold out at 20 units and established the company’s reputation for building exclusive, high-power e-bikes in small batches. The X9 builds on that platform with updated components and a slightly larger production run — 30 units total, each marked with a serialized plaque numbered 00-01 through 00-30.

65+ MPH, Powered by a Crystalyte Motor and FOC Controller

The X9 is rated for 65+ MPH, driven by the 9000W Crystalyte gearless hub motor. Power runs through HPC’s in-house Nucular 24F controller, which uses field-oriented control (FOC) and sine-wave switching rather than the cheaper trapezoidal control found on most hub motors. In practice, that means smoother torque delivery and noticeably less motor whine under acceleration — a real difference from the harsher, buzzier power delivery typical of basic hub-motor e-bikes, not just marketing language.

78V Battery with 100-Mile Range and Integrated Lighting

The X9 runs on a 78V, USA-made battery rated for up to 100 miles of range. That same battery also powers the bike’s integrated 4000-lumen headlight, so there’s no separate light battery to charge or swap — one battery handles the motor and the lighting system together.

Moto-Style Tires, Mullet Setup, and Custom Color Options

The X9 runs a 19″ x 3″ rear moto-style tire for added durability and flat protection, paired with a mullet setup — a smaller rear wheel and larger front wheel — that improves stability and cornering control at speed. The rear swingarm comes in satin black, with the standard bronze body offering contrast; HPC also offers custom color options at no extra charge if you’d rather go a different direction.

Optional Upgrades

Everything covered so far — motor, battery, lighting, tires — comes standard. HPC also offers a few optional upgrades for riders who want more: a custom-tuned suspension setup matched to your weight and riding style, a higher-capacity battery for extended range, and an upgraded braking system for additional stopping power.

Conclusion

The X9 isn’t a bike for everyone — it’s a niche, high-power machine built in small numbers for riders who specifically want that combination of speed, exclusivity, and hand-built construction. For most people it’s more of an enthusiast curiosity than a practical daily ride, but as a showcase of what’s possible in e-bike performance, it’s a genuinely impressive build.

FAQs

Is the Revolution X9 street legal?
At 65+ MPH, the X9’s top speed puts it well outside the federal e-bike classifications (Class 1-3, which top out at 20-28 MPH). It’s closer in capability to an electric motorcycle or moped than a standard e-bike, so street legality depends on state and local regulations rather than e-bike rules. Check your state’s vehicle code before riding one on public roads.

How is the Nucular controller different from a typical e-bike controller?
Most e-bikes use simpler trapezoidal motor control, which tends to produce more motor whine and rougher torque delivery. The X9’s Nucular 24F controller uses field-oriented control (FOC) with sine-wave switching, which delivers power more smoothly and with less audible motor noise.

Does the X9 still have working pedals?
Yes. The X9 includes a Schlumpf High Speed Drive, a two-speed pedal system designed to let riders pedal effectively at higher speeds. That said, given the motor’s power output, most riders will rely primarily on the throttle rather than pedal input for propulsion.
