Performance Review

The Happyrun Tank G50 is a class 3 designation e-bike that offers a top speed of 28mph. It has a moped-style design, making it great if you want to start your e-bike experience with a more adventurous ride. One thing I particularly like about this e-bike is its powerful 1500W peak motor which will surely give you a nice and stable riding experience on whichever terrain you want.

When it comes to range, the Happyrun Tank G50 gives a maximum range of 50 miles which I achieved with both pedal and throttle assist, it is a bit of a concern since the manufacturer claims 68 miles. The e-bike weighs an excessive 75 lbs, which is acceptable having a steel frame. You can ride the bike with both throttle and pedal assist, but of course, you have to keep in mind that this bike is quite heavy, so manual riding is the last option you should think of.

With a nominal power of 750W and a peak power of 1500W, the Happyrun Tank G50 delivers a powerful performance. Its 20×4″ fat tires enable easy cornering and smooth rides on flat surfaces or even riding on sand. Lastly, this e-bike provides a slow but steady hill climbing experience

Top Speed

The Happyrun Tank G50 has a top speed of 28mph, falling into the Class 3 designation. The twist throttle reached 28mph while on the 3rd pedal assist level, and I achieved 24mph on a flat road.



The Happyrun Tank G50 provides smooth and fast acceleration on flat ground. I felt a stable experience as it accelerated without any delay when I hit the throttle. However, I did notice a slight lag in the pedal assist.

Hill Climb

The Happyrun Tank G50 handles incline slowly but with ease, showing no issues. Whether using the throttle or pedal assist, the bike performs well on uphill terrain. On a 20-degree incline, I was able to ride it at a slow pace, but it gets the job done effectively.


The Happyrun Tank G50 is equipped with a 48V 20Ah battery, which provides reliable power for long rides. I found the 960Wh battery capacity to be quite dependable. 

I achieved a range of 50 miles on various terrains and riding conditions. I have a slight concern as the company claims a maximum range of up to 68 miles, which would likely require very slow riding and minimal throttle usage, but hey, 50 miles is no joke. Nonetheless, I find the range to be satisfactory and sufficient for most riding needs.

Ride Quality

The Happyrun Tank G50 provides a smooth and stable ride thanks to its dual suspension. It offers nimble steering, making it easy to maneuver on flat roads, off-roads, and even sand areas. 

The bike’s handling is stable, and the moped-style riding position adds to the overall comfort. The power delivery is responsive, ensuring a nice riding experience. When it comes to cornering, the bike’s 20×4″ tires offer great traction and I feel like it’s hugging the road. 

The weight distribution and ride stability are impressive, as the bike is capable of handling up to 265 lbs. Although there’s no added rear rack, the bike’s adventure-oriented design compensates for it. I particularly appreciate the BMX-style handlebar, which gives it a cool mountain bike look. 

Although the bike doesn’t have seat post suspension due to its moped-style design with a fixed saddle, the saddle itself is incredibly comfortable. It features a wide design with cushioning, ensuring a good ride. The saddle is also made by Happyrun, and I particularly love its clean and wide design, enhancing both comfort and aesthetics.



The Happyrun Tank G50 features mechanical disc brakes with 180mm diameter brake rotors. I appreciate the larger rotor size compared to the more common 160mm size found on other e-bikes. 

While the mechanical disc brake performs okay, I personally prefer the added responsiveness and smoother feel of hydraulic brakes, who doesn’t, right? It’s worth noting that when applying full brakes, there might be a slight noise, but overall, the braking performance is good.



The Happyrun Tank G50 features dual suspension, with a front fork suspension and a spring-loaded rear suspension, both made by Happyrun. The front fork has approximately 1 1/2 inches of travel, providing a smooth ride. The rear suspension has a typical 1/2-inch travel for a spring-loaded suspension of this kind. While the front suspension fork is not adjustable or lockable, the overall suspension performance is really good enough. It delivers a smooth and comfortable ride, whether on off-road trails, on grass, or even on minimal sand.

In terms of speed, both the Happyrun Tank G50 and the Euybike S4 offer a top speed of 28 mph, allowing you to cruise along swiftly and enjoy the thrill of the ride.

The Euybike S4 takes the lead with its 1000 W motor, delivering a strong and responsive performance. On the other hand, the Happyrun Tank G50 gives a slightly less powerful 750 W motor, which still provides a reliable and enjoyable riding experience.

One crucial aspect to consider is the range each model can cover on a single charge. The Euybike S4 offers an impressive range of 75 miles with its 1200 Wh battery, allowing you to embark on longer journeys without worrying about running out of power. In comparison, the Happyrun Tank G50 provides a range of 50 miles with its 960 Wh battery, which is still sufficient for various commuting and recreational purposes.

Happyrun Tank G50 vs Engwe M20

The Happyrun Tank G50 features a 750 W motor, while the Engwe M20 boasts a more powerful 1000 W motor. This means that the Engwe M20 offers a bit more power for acceleration and handling.

The Happyrun Tank G50 takes the lead with a speed of 28 mph, while the Engwe M20 has a slightly lower top speed of 25 mph. So if you value higher speed, the Happyrun Tank G50 would be the better option.

Considering battery capacity, the Happyrun Tank G50 has a larger 960 Wh battery, which allows for a range of 50 miles on a single charge. On the other hand, the Engwe M20 has a smaller 624 Wh battery, resulting in a range of 20 miles. If you require a longer range for your rides, the Happyrun Tank G50 would be more suitable.

Weight-wise, the Engwe M20 is slightly heavier at 34.9 kg (77 lbs), while the Happyrun Tank G50 weighs 34 kg (75 lbs). Both models are relatively lightweight and manageable for transportation and storage.

The Engwe M20 comes equipped with triple suspension, offering enhanced shock absorption and a smoother ride over rough terrain. The Happyrun Tank G50 features dual suspension, which still provides a comfortable riding experience but may not absorb bumps as effectively as the Engwe M20.

Price-wise, both models are priced at $1,299, making them equally affordable options within the same price range.

Here’s a brief comparison of these three electric bikes.

The Happyrun Tank G50 is a moped-style bike that is truly impressive when it comes to performance. Its adventurous appearance caught my eye, and the powerful motor that reached up to 1500W peak power, ensured a nice ride. The inclusion of dual suspension and 20″ fat tires contributes to a remarkably stable and comfortable journey. What’s more, the affordable price of $1,299 gives this bike an exceptional value for money.

While the mechanical brake performs well, I can’t help but think that hydraulic brakes would offer even better-stopping power, especially considering the bike’s top speed of 28 mph and its intended offroad use. Additionally, although the steel frame provides durability, I’m sure a lighter frame material could improve maneuverability without sacrificing ruggedness.

All in all, the Happyrun Tank G50 is a fantastic bike that excels in both daily commuting and mid-level off-road adventures. Its powerful motor, dual suspension, and attractive price point make it an excellent choice for riders seeking a reliable, comfortable, and versatile riding experience.
