Cyrusher Trax

Overview

If you have never heard of Cyrusher, they are a brand best known for building very loud, vibrant electric bikes. The Cyrusher Trax is a perfect example of that design philosophy, featuring a bright, head-turning frame that immediately puts a smile on my face. But this is far from a normal-looking fat tire e-bike. It sits in a more premium tier, coming in around $2,500, and it packs a substantial amount of high-end gear to justify what you pay for.

When I first got my hands on the Trax, its sheer physical footprint stood out. It is massive. Step-through frames usually prioritize accessibility over aggressive styling, but Cyrusher managed to blend those two concepts here. They integrated a heavily reinforced middle section into the step-through area, giving it a distinct, almost motorcycle-like silhouette. I spent a lot of time evaluating whether all these unique, visually striking choices actually translated into a better ride, or if they were just there for show.

Real-World Performance

In my testing, the power delivery of the Cyrusher Trax proved to be a mixed bag of gentle cruising and high-speed capability. The bike is equipped with a 750 W Motor that peaks at 1500 W and delivers 80 Nm of torque. You might expect a massive punch off the line with those numbers, but when I maxed everything out and held the throttle down, I found the acceleration to be very gentle and slow. It doesn't snap your neck back, but if you keep holding that half-twist throttle, it will eventually climb all the way up to 28 mph.

Because this is a torque sensor e-bike, you really have to work for your speed if you choose to pedal. I tested the manual pedaling effort in the seventh gear and found that with casual pedaling, I was only hitting about 20 mph. To actually reach that 28 mph top speed under my own power, I really had to crank down on the pedals. I appreciate this setup because torque sensors are fantastic for single-track trails and precise off-road riding, yet Cyrusher still gave me full power on demand through the throttle. A lot of brands cap throttle speed at 20 mph, so having the best of both worlds makes this an excellent high-speed commuter.

Battery life and range are also strong points. The Trax uses a hefty 52 volt 20 amp hour battery, which is a step up from the standard 48 volt packs I usually see on fat bikes. Cyrusher claims a range of up to 56 miles, and that larger capacity definitely provides peace of mind on longer rides. They also rate the battery for 800 charge cycles, meaning you could theoretically squeeze over 44,000 miles out of this pack before it gives up the ghost.

Design & Build Quality

The physical geometry of the Cyrusher Trax is fascinating. When I measured this bike in my garage, it came out to 80 inches long. For context, the standard fat bikes I test usually run around 75 inches. That five-inch difference might not sound like a big deal, but out on the road, it translates to drastically better stability. I was able to ride this bike with no hands, and there was absolutely zero speed wobble in the handlebars. Part of that rock-solid balance also comes from the thick reinforced piece in the middle of the step-through frame, which counteracts the flex you typically get in open-frame designs.

However, that structural integrity comes with some aesthetic and physical costs. For one, the welding scars on this frame are pretty heinous, especially around that thick middle support piece. I did notice the welds up near the head tube were nice and smooth, but the inconsistency is disappointing for a premium bike. Furthermore, this is an exceptionally heavy machine. It tipped my scales at 87 lbs, making it a good 10 to 15 lbs heavier than most step-through e-bikes. You will feel that weight if you ever have to lift it.

In terms of rider comfort, I really liked the saddle design. It features a cool stripe down the back and angled vents that shoot air up to keep you cool. I am a 5'11 guy, and Cyrusher states the bike fits riders from 5'4 up to 6'6. For me, the riding posture felt fairly aggressive. The Kenda 24x4 inch all-terrain tires are what I would call a gravel tire rather than a knobby off-road tire. They felt smooth and capable on city streets and packed trails, but I wouldn't push them into deep mud or loose off-road conditions.

Key Features

One of the standout features I tested on the Trax is its dual suspension system. Up front, you have a motorcycle-style hydraulic spring suspension. It offers good travel, and you can completely lock it out by turning the dial on the right all the way to the left. But what truly makes this bike unique is the rear air suspension. You can remove a cap to access an air valve, allowing you to add or remove pressure based on your ride preference. It also features a physical switch to adjust the rebound. In my demonstration, flipping from slow rebound to fast rebound made a noticeable difference in stiffness.

The cockpit is loaded with high-end tech, starting with a pretty large color LCD screen in the center. On the left side, there is a control pad for the lights and horn, plus buttons to change pedal assist levels. Interestingly, when I dug into the advanced settings on the display, the only thing I could actually change was the top speed of the bike. Over on the right side, you get a solid 9-speed trigger style shifter and the half-twist throttle.

Unfortunately, Cyrusher cut a few corners on the accessories. The included pedals have a cheap feeling, and while they generously include two wrap-around rearview mirrors, they are the absolute cheapest mirrors you can buy. The manual tail lights also bothered me; at this price point, I expect tail lights to be wired directly into the smooth hydraulic brakes to act as actual brake lights. Finally, the handlebar grips are massive. While they look cool, the oversized diameter caused me hand fatigue when I took the bike off-roading.

Who It's For

I would recommend the Cyrusher Trax to riders who want a highly stable, aggressively styled commuter that can confidently handle light gravel trails and city streets. The longer 80-inch wheelbase and reinforced step-through frame make it perfect for someone who struggles with balance or speed wobble on traditional step-through frames. It is also ideal for the speed demon who wants the nuance of a torque sensor for pedaling, but still wants the ability to hit 28 mph strictly using the throttle.

Who Should Skip It

If you need a lightweight, nimble e-bike that you can easily carry up a flight of stairs or load onto a standard car rack, you should absolutely skip this bike. At 87 lbs, it is a beast to maneuver when you aren't riding it. Furthermore, if your primary goal is hardcore off-roading, the massive grips that induce hand fatigue and the non-knobby tires will likely leave you frustrated.

How It Stacks Up

When looking at the broader premium fat tire e-bike market, the Cyrusher Trax stands out purely based on its sheer size and unique suspension setup. Most competitors in this price bracket rely on standard rear coil shocks, so finding an adjustable air shock with a dedicated rebound switch is a major advantage. However, many rival brands in this premium tier do a better job at hiding their welds and managing cable routing. The front cords on the Trax are a bit messy compared to the fully integrated wiring harnesses I've seen on similarly priced commuter fat bikes. Despite those aesthetic drawbacks, the Trax outshines its peers in raw stability thanks to that elongated 80-inch frame.

Final Verdict

Overall, the Cyrusher Trax is an incredibly stable, fast, and feature-rich electric bike that brings a lot of high-end gear to the table for around $2,500. While I wasn't impressed by the cheap pedals, manual tail lights, or the heinous welding scars near the center of the frame, the ride quality itself is exceptional. The combination of a large 52 volt 20 amp hour battery, an adjustable rear air suspension, and the ability to comfortably hit 28 mph on throttle alone makes this a highly capable machine. If you can handle the 87 lbs of weight, this vibrant fat bike delivers a phenomenal balance of power and stability.
