I don't use apps for scooters. Give me complete control of the thing. It's nice to be able to control the speed through an app but most of the time it's a nuisance. I was able to top out at 19 miles per hour thanks to the 500- watt motor after I enabled the top speed.

You are supposed to hit 21 miles per hour. The Apollo Air has a stated weight capacity of 220 pounds. I was able to ride throughout New York City on it. When I traveled from Bed-Stuy, Brooklyn, over the Manhattan Bridge and back, I found myself kicking off the ground to get home. Apollo's 31 mile claim feels like a stretch for anyone, but I'm sure most people can get closer to 20 miles out of it.

The air-filled tires make for a smooth ride. I don't feel anything on the road. The front drum brake was usually enough to bring me to a halt. The brakes did the job when I needed to stop.

This scooter doesn't have good acceleration. The air moves on the asphalt like a tumbleweed when the light is green. It will take some time to get to its top speed. The speeds on inclines will be between 11 and 14 mph. It isn't powerful enough to cruise up slopes.

My friend and I both had around two bars of juice left on our rides. He was going at 20 mph and I was stuck at 14 mph. Sometimes the Apollo slows down when it dips to two bars. It's not permanent.

It's a perfectly fine scooter, but I don't like the fact that it costs $1,200. The Niu, which is 5 pounds lighter, goes up to 20 mph, and is very fast. They both deal with inclines the same way. The Niu K Qi3 Pro costs $799 The price difference is large.

Niu has a dealer network that makes it easier to fix problems. There are five Apollo service centers in the United States. I would like to say that Apollo's customer service is better, but I have found complaints about both brands. If you have a lot of money to spend on a scooter, I would recommend the Mini 4 Pro. It has a slightly more reliable range and is easy to fold.
