Amped Cycle Reviews
The Emojo Street X is a lightweight, teen-focused moped-style e-bike with a 750W motor, 48V 15Ah battery, sticky 20x4 tires, excellent hydraulic brakes, integrated lighting, and a clean frame that hides the battery underneath the seat. It ships as a calmer 20 mph Class 2 bike, but after unlocking it to approximately 28 mph, the Street X felt noticeably quicker, more useful, and much more complete.
Overview
The Emojo Street X is geared toward teens who need a bike for school, riding around town, and gaining a little independence without jumping straight to a 40 mph electric dirt bike.
Out of the box, that idea makes sense. The Street X comes limited to 20 mph, uses a 750W motor, carries a Class 2 label, and includes safety-focused equipment such as hydraulic brakes, a bright headlight, a brake light, and rear turn signals.
My first ride left me a little conflicted. The bike felt well made, looked great, and handled nicely, but the combination of a 20 mph limit, no suspension, and a price near $1,400 made it difficult to get excited about, especially when there are bikes half that price that are faster and more comfortable.
Unlocking it to approximately 28 mph changed the experience. It did not turn the Street X into a monster, but it gave the bike enough speed to feel lively and made much better use of its motor, brakes, tires, and lightweight frame.
Emojo currently lists the Street X at $1,399, with a 750W motor, 48V 15Ah battery, hydraulic brakes, 20×4 tires, an aluminum frame, and UL 2849 certification.

Performance: Motor and Speed
The Street X uses a 750W continuous rear hub motor with a claimed 80 Nm of torque.
In its factory configuration, the bike topped out at a true 20 mph. Acceleration was smooth and deliberately controlled. It did not feel underpowered, but the controller eased into the motor output instead of hitting hard from a stop.
That calmer tuning fits the teen-focused design. It feels predictable and easy to control, especially for a first e-bike. However, 20 mph also made the Street X feel like it was holding something back.
Once unlocked, the bike reached approximately 27–28 mph and felt much more awake. The difference between 20 and 28 mph sounds small on paper, but it completely changed the personality of the bike. It became peppier, more capable on the road, and better suited to keeping pace on neighborhood streets.
The Street X also benefits from being relatively light for a moped-style fat-tire bike. It responds quickly to steering input, changes direction easily, and feels more tossable than many heavy steel-frame, full suspension alternatives.
The throttle remains active regardless of pedal-assist level, and the motor still pulled well even as the battery dropped below half. The bike is not brutally fast, but it is quick enough to be fun once fully opened up.
One complication is the unlocking process. The speed setting required assistance from Emojo, and the bike later reverted to its 20 mph limit after sitting for about a week. That meant repeating the unlocking process. A simple menu option for switching between Class 2 and faster settings would make the bike much easier to live with.
Battery: Specs and Range
The Street X uses a 48V 15Ah lithium-ion battery, giving it approximately 720Wh of capacity. The battery is hidden underneath the seat, which helps preserve the clean, almost non-electric appearance of the frame.
Emojo advertises up to 65 miles of range, although that figure will depend heavily on speed, rider weight, terrain, temperature, and assist level. Charging time is listed at approximately 4–6 hours.
During the combined daytime and night testing, the bike covered approximately 20 miles and still displayed around 40% battery. Some of that distance was completed while limited to 20 mph, which naturally used less energy than riding at 28 mph.
Based on that result, realistic range should fall somewhere around:
- 25–30 miles with faster, throttle-heavy riding
- 30–40 miles with mixed throttle and pedal assist
- More range at 20 mph with conservative assist
The battery position is one of the smarter parts of the design. Hiding it under the seat lowers the visual bulk and keeps the main frame area open. The placement also contributes to the balanced, nimble handling.
Emojo lists the Street X as UL 2849 certified and also advertises UL 2271 certification on the product page.

Real-world results vary with rider weight, terrain, and weather.
Comfort and Build Quality
The bike uses an aluminum frame and weighs approximately 82 pounds with the battery, making it lighter than many moped-style fat-tire bikes.
That lower weight improves almost everything about the riding experience. The bike is easier to maneuver, easier to push around the garage, quicker to respond, and easier to stop. The frame also feels cohesive rather than like a generic bike assembled from random parts.
The riding position is upright and comfortable. The extended seat offers enough room to shift position, and the bars have enough rise to avoid an aggressively hunched posture. The relatively low standover height should also work well for many teens and shorter riders.
The biggest comfort problem is obvious: there is no suspension.
The Street X has a rigid fork and a hardtail rear. On smooth pavement, it feels completely fine. The fat tires and padded seat absorb enough vibration to keep normal street riding comfortable. On larger bumps, curbs, broken pavement, or rough trails, the bike can hop and send the impact directly through the frame.
They do offer the upgraded Streetrod model, which includes a bigger battery and rear shock, but no front suspension for some reason.
The lack of suspension does have one benefit: less weight and more direct handling. But at this price, at least a basic front suspension fork would make the Street X much more versatile.
The 20×4 tires deserve credit. They felt extremely sticky on warm pavement, almost squeaking like car tires while moving the bike around the garage. That grip helps the Street X corner confidently and gives the bike a planted feeling despite its lighter weight.
Other Unique Features
Excellent Star Union hydraulic brakes
The hydraulic brakes are almost overkill for the factory 20 mph limit. They stop the bike extremely quickly and provide excellent lever feel. Once the bike is unlocked to 28 mph, the upgraded braking hardware makes much more sense.
Integrated battery design
The battery sits underneath the seat rather than hanging from the down tube. That creates a cleaner silhouette and leaves the center of the frame open.
Color LCD display
The display shows speed, pedal-assist level, battery information, watt output, trip data, and battery voltage. The voltage readout is especially useful because battery bars alone can be vague.
Headlight and brake light
The headlight produces a wide, usable beam. It is not the brightest e-bike light I have tested, but it was sufficient on a completely dark trail. The rear light is bright and functions as a brake light.
Rear turn signals
The Street X includes integrated rear turn signals, and the display shows when they are active. The signals are helpful at night, although they are fairly small and difficult to notice during the day.
Multiple color options
Emojo currently offers the Street X in Matte Black, Aqua Gray, Chromed, and Metallic Green.
The chrome version is probably the most distinctive, but the black test bike still has a clean, understated look.etter than the cable brakes often found on cheaper bikes.
Negatives
The lack of suspension is the biggest weakness. It limits how fast the Street X can comfortably travel over rough surfaces and makes large bumps much more jarring than they need to be.
The price is the second issue. At $1,399, the Street X costs considerably more than many budget e-bikes with similar speed, larger batteries, and full suspension. The premium appears to go toward the aluminum frame, lower weight, hydraulic brakes, integrated design, lighting, safety certification, and teen-focused positioning rather than raw specifications. When compared to bikes from Macfox and super73, the Street X is much cheaper though.
The factory 20 mph limit also holds the bike back. It makes sense for a Class 2 teen bike, but the Street X feels much better at 28 mph. Unfortunately, switching between those configurations is not simple, and the unlocked setting reset itself after the bike sat unused.
The turn signals are another mixed feature. It is great that they are included, but they are small and not particularly noticeable in daylight.
Pedaling is limited by the single-speed drivetrain. Pedal assist three feels usable, but above that, the cranks start spinning too quickly and contribute very little. This is still mainly a throttle-oriented moped-style bike.
Finally, there are no passenger pegs. Despite the extended seat, the Street X is better treated as a one-person bike.

Final Thoughts
The Emojo Street X took a while to fully make sense.
During the original test, it felt like a well-built but expensive 20 mph e-bike with no suspension. The brakes were excellent, the tires gripped well, and the frame felt polished, but the overall package was hard to justify strictly through performance and value.
After unlocking it to 28 mph, the Street X became a much better bike.
The extra speed allowed the lightweight frame, responsive handling, strong motor, sticky tires, and oversized brakes to work together. It felt quick, agile, and genuinely fun without becoming intimidating.
This still would not be my personal choice as an adult rider because suspension matters to me. But I also do not think I am the target customer. The Street X makes the most sense for a teen who needs a stylish, relatively lightweight bike for school, friends, and neighborhood transportation—and for parents who care more about controlled performance and quality components than getting the largest motor possible.
At 20 mph, it is a safe and predictable Class 2-style bike. At 28 mph, it becomes the bike it always felt capable of being.
It is not the cheapest option, and it is not the most comfortable over rough terrain. But it is a cohesive, well-built teen e-bike with excellent brakes, confident handling, good lighting, and a surprisingly fun personality once unlocked.
