I just bought two scooters from a garage sale. The only brand I can see on the floorboards it says E-SCOOTER. I charged it up and everything seemed to work on it, the lights, turn signals, horn. When I sit on it and turn the throttle it doesnt want to move. If I stand up next to it and turn throttle it will go but barely, even at full throttle. Any idea on what could be the problem?

Support V is for Voltage
If you put some photos of the scooters in here, then someone might well recognize the scooters and you will be a big step closer to a solution!

Most likely the problem is bad batteries that will no longer hold a charge. Do you have a voltmeter or DMM?
Here are some pics of the scooter, maybe someone will recognize it. And yes I do have a voltmeter, how can I check to see if batteries are good?
Your scooter probably has two 12-volt Sealed Lead Acid batteries wired in series to make 24 volts (nominal). There would be a short "jumper" wire from one battery's positive terminal to the other battery's negative terminal. You will want to get your voltmeter reading from the two battery terminals that are NOT connected by the jumper. A fully-charged pack should read above 26 volts. With the voltmeter attached, turn the scooter on and roll the throttle with the front wheel against a wall or curb so it can't go forward. This will put a load on the batteries and if they drop several volts almost immediately, they need to be replaced.
Another quick test might be to turn on the headlight and then note the brightness. Sit on the scooter and turn the throttle. Does the headlight dim? A lot?
Hope this will help, let us know what you find.
