Compare the Segway Ninebot Air T15 and the Segway Ninebot ES4

When it comes to electric scooters, Segway Ninebot is a popular name in the market. This company has produced several models loved by riders around the world, but today, we are going to focus on two well-regarded models — the Ninebot Air T15 and ES4. The first major difference lies in their design. The T15 displays a futuristic minimalist design, its folded dimensions are very slim and it is lighter, making it easier for transportation. On the other hand, the Ninebot ES4 maintains a more classic electric scooter look, it is heavier but is designed with a more powerful motor.

Concerning speed and range, ES4 definitely takes the lead. It has a top speed of 18.6 mph as opposed to T15’s 12.4 mph, and a maximum range of 28 miles as compared to T15's 7.5 miles. Therefore, for riders valuing speed and distance, the ES4 would be a better choice. However, if you are expecting an easy function with a smooth ride, the Air T15 will impress you with its energy-efficient, innovative regenerative braking system and robust tires which ensures a comfortable journey.

Considering battery life, the ES4 outperforms the T15. ES4 comes with an additional battery pack offering extended ride time, while the T15 features an integrated battery design that is easy to charge but with lesser battery capacity.

In terms of smart features, T15 impresses with the innovative LED digital dashboard, and the Segway-Ninebot app allows riders to manage rides at fingertips. The ES4, while it does support the Segway-Ninebot app, doesn't have an LED digital dashboard.

To sum up, if you value portability, innovative design, and smart features, the Ninebot Air T15 might cater to your needs, whereas for those prioritizing speed, range, and battery life, the Ninebot ES4 would be more suitable.
