Really like design of scooter but battery is weak if you live anywhere with hills. Battery life drains quickly if you have to go uphill.

Also unlike other lithium battery powered tools, the battery gets weaker and weaker and bike goes to 4 miles per hour once it is weak. I wished it remained full power and then just dies quickly.

Battery indicator not accurate. Might show 2 bars but then as soon as you move it goes to 0 bars.

Brakes also a bit weak and need both front and back brakes to stop quickly. Brake handles not very smooth. Maybe I got a bad one but brakes not smooth and takes both brakes to stop it quickly. My Bird ES400 brakes easily and quickly with just a single button.
