Meet your new Cyrusher Zenith!

Featuring a classic, high-rigidity step-over frame design, the Cyrusher Zenith delivers a bold, commanding stance built for all-terrain exploration. Prepare to find yourself heading outdoors more often, riding further, and exploring city streets, gravel paths, and mountain trails with unmatched comfort, control, and confidence.

Industry-Leading Electrical Safety

UL 2849 Certified: This is the gold standard for eBike electrical systems. It means the entire drive train—including the motor, controller, display, and charger—has undergone rigorous third-party testing (via SGS) to prevent electrical failures and fire risks.

UL 2271 Certified: This specifically covers the lithium-ion battery. It ensures the "heart" of your bike is protected against overcharging, short-circuiting, and impact, providing a safer charging experience in your home or garage.

Advanced Weather & Waterproofing

IPX5 & IPX7 Protection: Engineered to confidently handle changing weather conditions, the Zenith features robust water protection. With an IPX5 overall rating and key electronic components sealed up to IPX7 standard, the bike is built to handle downpours and wet road splashes, ensuring the core electrical cells remain dry and protected.

Meet your new ride:

Up to 60 Miles of Range: A high-capacity 52V 15Ah (780 Wh) LG 21700 battery powers your daily commutes or extended adventures. Think of Watt-hours as being the size of your gas tank (the average mid-range eBike has around 500 to 650 Wh).

Max Speed: 20 MPH out of the box but can be unlocked for 28 MPH.

Watts with the Torque?

The Cyrusher Zenith is propelled by a robust 52V, 750W rear hub motor (peaking at 1,280W) that serves up a powerful 80–95 Nm of torque. This heavy-duty power configuration means you can effortlessly flatten steep inclines, accelerate smoothly from a dead stop, and handle headwinds or heavy loads with ease.

Unlike standard e-bikes, the Zenith utilizes an advanced, switchable sensor system, allowing you to transition between torque and cadence tracking with a single touch. Being able to switch between a torque sensor and a cadence sensor gives you two completely different e-bike personalities on the exact same machine. Instead of forcing you to choose between a "workout/natural bike feel" or an "effortless mopedy cruise," the Cyrusher Zenith lets you toggle between both depending on your mood, energy level, or terrain.

Pair those options with 5 levels of Pedal Assist (PAS) and you have an incredibly diverse ride. What exactly is "pedal assist"? The motor measures your pedaling and basically matches it with a little "ooomph" of its own. With 5 different levels of pedal assist, you can decide if you want just a tiny bit of help or quite a bit.

What Class Rating does the Cyrusher Zenith have and why should I care?

This premium eBike offers the ultimate flexibility, capable of switching between Class II and Class III modes. While it ships as a legal Class II setup, you can easily unlock its full potential through the smart, colorful LCD control panel.

Understanding the Class Ratings: Why Versatility Matters:

Class II (Throttle & Pedal Assist): This is the "out of the box" setting. The bike includes a twist/thumb throttle that can propel you up to 20 MPH without any pedaling required, perfect for effortless cruising or getting a boost from a standstill.

Class III (High Speed): This unlocks the eBike's top speed of 28 MPH via pedal assist. It is the ideal setting for commuters who need to keep pace with traffic and cover long distances quickly.

Understanding local and state ebike regulations is essential because laws vary significantly regarding where different class types are permitted, and staying informed ensures you can enjoy the full range of "Class I/Class II/Class III freedom" while remaining legally compliant and safe on every road and trail.

Quality Components:

Battery and Charger: The Zenith is powered by a high-performance 52V 15Ah (780Wh) removable battery pack built with premium LG 21700 cells. Engineered for extreme safety, reliability, and longevity, the entire battery pack is officially UL 2271 certified and managed by a Smart BMS. The housing features a robust waterproof rating, providing heavy-duty protection against severe weather. To minimize your downtime between rides, the system includes a smart charger (2A) to replenish the high-capacity cells quickly (approx. 7–8 hours).

Shimano 7-Speed Gears: The Cyrusher Zenith features a high-performance Shimano 7-speed drivetrain (TY500 Rear Derailleur) engineered for smooth, reliable shifting across varied terrains. This gearing configuration provides the perfect mechanical range to efficiently tackle steep climbs and maintain a comfortable pedaling cadence at top speeds.

Logan Hydraulic Disc Brakes: The Zenith is equipped with a premium Logan 2-piston hydraulic disc braking system engineered for maximum stopping power and precise control. This setup offers superior heat dissipation and exceptional braking leverage under heavy loads or high speeds. The system features an integrated electronic brake power cutoff mechanism—the moment you pull the levers, power to the motor is instantly disconnected, ensuring rapid, safe, and reliable stops in any weather or terrain condition.

26" x 4.0" All-Terrain Fat Tires: The Zenith comes factory-equipped with premium 26" x 4.0" fat tires. Engineered specifically for all-terrain versatility, these tires absorb harsh bumps while delivering exceptional grip across city asphalt, sand, snow, or unpaved trails.

Strong and Rigid Step-Over Frame: Built to handle the demands of off-road exploration and daily commuting, the Zenith is engineered around a 21" high-strength 6061 Aluminum Alloy step-over diamond frame. This sturdy chassis provides maximum frame stiffness and structural strength for high-speed stability.

Suspension: The Cyrusher Zenith features a front coil-spring suspension fork with lockout that absorbs heavy impacts from road ruts, potholes, and rough trail terrain to reduce wrist and arm fatigue.

Start me Up! The Cyrusher Zenith is ready to go with the press of a button on the control pad!

Is this a folding eBike? No. The Cyrusher Zenith does NOT fold.

Lights, Displays, and Safety Features: Engineered for daily safety, the Zenith features an ultra-bright anti-glare LED front headlight and a powerful integrated rear light to keep you visible to traffic. All your critical ride data is clear at a glance via the mid-mounted full-color smart LCD display.

350 lb Max Load Weight: The Cyrusher Zenith supports up to 350 pounds combining the rider and any cargo, making it easy to carry gear, work essentials, or bags.

Is the Cyrusher Zenith Step-Over your size? The recommended rider height for the Cyrusher Zenith is 5'1" through 6'4". The step-over geometry ensures a strong stance and comfortable fit across a wide range of body types.

Does the Cyrusher Zenith have a sturdy kickstand? Yes! It comes equipped with a heavy-duty side kickstand.
