The scooter uses batteries specifically designed for deep discharge applications. If your new batteries are not lasting then they may only be suitable for standby or backup type applications like for your house alarm system or garage door opener when the mains power goes out.

No. We get batteries from a local supplier and they work just as well. are by far the most common problem with razors because people dont keep them charged.

get some new batteries.
yours are worn out.

My guess is the batteries have gone bad. They only last about a year before they need to be replaced. You can buy them fairly cheap off of Ebay.

Its the black button next to the switch and charger port.

Just buy a new rear wheel. The wheel is not meant to come apart without breaking a couple fingers in return. Besides the new tube is about 15 dollars add the shipping and for another 20 dollars you can get it brand new complete, wheel, tube, rim, axle. I'm not saying it can't be done but why put yourself through this.
