I test electric scooters for a living, and these are the 7 best Prime Day deals I've found

Razor Power Core E100: was $209 now $152 @ Amazon
The best electric scooter for kids is now more than $50 off. This great intro scooter has a quiet 100W motor, a sturdy build, and enough battery life to keep your kid entertained for hours — safely, of course. 

Segway Ninebot Kick Scooter E2 Plus: was $399 now $299 @ Amazon
An excellent choice for commuters, the Segway Ninebot Kick Scooter E2 Plus is on sale for $299 at Amazon. Its 350W motor can reach a top speed of 15.5 mph, so it's not the most powerful, but could be a good option for teens. However, one of its most fun features is its set of RGB lights under the footboard — it lets you light up the night with a full rainbow of beautiful colors. Note: this has sold for $279 in the past.

NIU KQi3 Max: was $999 now $674 @ Amazon
Editor's Choice! One of the best all-around electric scooters we've tested is $150 off in this sale. In my Niu QKi3 Max review, I said this model offers lots of power for getting up hills, plus the range to get you anywhere you need to go. I also really liked its disc brakes, which help it stop fast and look great.

NIU KQi Air: was $1,399 now $949 @ Best Buy
Best electric scooter! My pick for the best electric scooter is now on sale for a hefty discount. In my NIU KQi Air review, I loved this model for its great range and smooth ride performance. It's super light, coming in at 26.5 pounds, which makes it one of the most portable scooters around. You also get useful turn signals and anti-theft features.
