Mearth S Pro vs Unagi E500 Review


The Mearth S Pro and the Unagi Model One E500 both have gained recognition for their design, portability, durability, and performance. However, both have unique differences that make them stand out from the rest. Will these differences outweigh one of these e-scooters over the other?

What sets the Mearth S Pro apart from the Unagi E500 is its swappable battery system. Unlike most e-scooters, the Mearth S Pro keeps its battery inside its stem for easy switching of batteries. This battery system allows riders to extend their trips and easily replace their battery with a fully-charged one when they run out of power on the road. 

Meanwhile, the Unagi E500 boasts dual motor power that can reach a peak of 1000W. This makes the Unagi not only a portable and aesthetic e-scooter but also a very powerful commuter e-scooter. No wonder that the Unagi E500 has become one of the most popular commuter e-scooters worldwide. For a full look at this e-scooter, here’s our Unagi E500 review.

For this review, we will be comparing the similarities and differences of the Mearth S Pro and Unagi E500, and see which one is better.

Top Speed

When it comes to speed, both are tied as both e-scooters have a default speed of up to 25 kph only as per electric scooter laws in Australia. However, when ridden on private property, the Mearth S Pro can still be modified to reach up to 32 kph. For those who are looking for faster speeds, the Mearth S Pro wins over the Unagi E500.


Surprisingly, the Unagi E500 can only deliver a maximum of 25 km of distance. Meanwhile, the 360W motor of the Mearth S Pro can take you a max range of 45 km per charge. In real road conditions, this maximum range can still shorten, so having a higher ideal max range is better. The Mearth S Pro is a winner again in terms of range.


The Mearth S Pro contains a 36V, 5Ah 10Ah or 6.4Ah, 230.4Wh Lithium-ion battery. On the other hand, the Unagi E500 has a 33.6 V 9.0Ah 282Wh Lithium-ion battery. Both are relatively good batteries. 

However, when it comes to total longevity on the road. The Mearth S Pro has the upper hand thanks to its swappable battery system. Riders can just carry multiple batteries and switch them with the drained ones. With this kind of battery system, you can ensure you can always get to your destination, no matter how far it may be. 

On the other hand, the Unagi E500 also comes with advanced battery features such as an intelligent battery management system, which prevents overcharging, short circuit, and more.

When it comes to function and power, both e-scooter batteries are tied. However, in terms of the distance that each battery can give, the Mearth S Pro is better.


When it comes to controls, both electric scooters both share a simple display. The Unagi E500 showcases a small bright display, ergonomic throttle and brake controls, and rubber handlebars. On the display, you can see your current speed, speed mode, and battery level. For the Mearth S Pro, you also get a small, coloured display, a brake lever, a throttle, a bell, and easy-grip handlebars. On the display, you can see your current speed and battery level.

There’s not much difference between the two in terms of function, so it all goes down to preference. If you prefer the T-style, futuristic design of the Unagi E500’s cockpit, then go for this e-scooter. Otherwise, if you prefer the rounder and classic look of the Mearth S Pro, then it’s also a great choice.


The Mearth S Pro features 8.5-inch pneumatic tyres, while the Unagi E500 sports 7.5-inch solid ventilated tyres. It’s common knowledge that pneumatic tyres offer better ride quality than solid res. After all, pneumatic tyres provide more cushion, especially at high speeds. So, the Mearth S Pro’s pneumatic tyres are better.

However, the Unagi E500 designed their solid tyres with air pockets to offer more cushioning compared to a completely solid tyre. Somehow, it does the job, but there is still a noticeable difference in quality when riding pneumatic tyres. The Unagi E500’s solid air pocket tyres can’t beat the Mearth S Pro’s pneumatic tyres, but it’s a good effort.


When it comes to portability, the Unagi E500 is a clear winner. Based on the weight alone, it’s 3 kg lighter than the Mearth S Pro. In fact, it’s one of the lightest electric scooters that you can find on the market. The Unagi E500 also has an easy-folding mechanism that allows you to fold or unfold your e-scooter in just seconds. The flatter part of the stem makes the e-scooter easier to hold, so you don’t lose grip while carrying it on the stairs. It’s also quite compact with a folded dimension of 960mm x 420mm x 380mm.

Meanwhile, the Mearth S Pro is still quite portable. With a 13.5 kg weight, it can still be called a lightweight electric scooter. It has a one-touch folding mechanism, which quickly folds and unfolds the stem and locks it into place. The Mearth S Pro also has a compact size with an unfolded size of 1073mm x 420mm x 450mm. However, the Unagi E500 is smaller.

Ride Quality

As mentioned previously, the Unagi E500 has less comfort when it comes to riding quality due to its solid tyres. Moreover, it also has no suspension, so rides can be a bit bumpy when driving at high speeds on rougher roads. On the other hand, the Mearth S Pro can take on rougher roads and still provide a stable and comfortable ride. Although, since it’s not built for off-roading, you will experience rattling if you ride on rocky paths.

Build Quality

Both electric scooters are very well-built. The materials feel very solid and premium to the touch and the components are well integrated and screwed in. The controls and throttles don’t feel cheap and are very responsive. Despite being lightweight e-scooters, the Unagi E500 and Mearth S Pro are pretty sturdy. Overall, these electric scooters deliver exactly what you pay for, so you can expect either e-scooter to last for years, as long as you take care of it.


The Mearth S Pro has a retail price of $999, but you can get it for only $899 here at Scoot City for a limited time only! Meanwhile, the Unagi E500 has a selling price of $1,695. It’s definitely on the expensive side, but that’s because it’s a premium electric scooter. When you buy the Unagi E500, you get a lightweight, durable, and long-lasting e-scooter that performs and turns heads. But if you’re on a budget, then the Mearth S Pro is a great alternative.


Unagi offers a one year warranty. However, Unagi offers a 30-day return policy that’s valid for any reason. This means change-of-mind returns are accepted, as long as you return the e-scooter within 30 days after its purchase. Meanwhile, Mearth provides a two-year warranty for the frame and a one-year warranty for the battery and motor.
