I am not familiar with how scooters run specifically but I would bet the motor does disengage seeing how it is electric.

  1. rotate the rear wheel until the hole in the sprocket lines up with the tyre valve.
  2. insert the tyre valve extension through the hole and attach it to the tyre valve
  3. inflate the tyre to the correct pressure (usually 45psi)
  4. remove valve extension and put in a safe place for next time.
Inflating the rear tyre is detailed in the owners manual, which you can download from the Razor web site.

The battery can be recharged only so many times before it is no longer usable. You probably need a new battery. It runs with no load because it does not need much current (amperage). With a load it needs a lot more current than the battery can actually put out. The charger brings the voltage of the battery back up to normal but the current is not there due to a worn out or defective battery.

I posted a similar issue about the same scooter. If you do replace the batteries and still experience the same issue, check the wiring for loose wires and possibly replace the fuse.
After replacing the fuse and connecting wires, my scooter doesn't pop the fues with every use anymore.

These are the instructions for adjusting the chain. They are taken directly from the manual available at http://ep.yimg.com/ty/cdn/razorama/e100e200e300manual.pdf

To adjust the chain:
1. Loosen the axle
2. Loosen the brake anchor (this is attached with the small bolt in the long slot on the left side of the rear fork)
3. Tighten the tension adjusters on the axle 1/8 to 1/4 turn to tension the chain. Tighten both adjusters the exact same amount to maintain the wheel alignment.
Note: this system of adjusters is common to motorcycles and BMX
bicycles so I your are not familiar with it, if you know anyone who is,
they would not have a problem adjusting it for you.
Chain tension: The chain should be "just not-quite snug" in other
words, not taut or sloppy loose. BE CAREFUL NOT TO ADJUST TOO TIGHT. The tensioning system can easily impart too much tension and snap the chain or bend the motor output shaft. Turn the adjusters 1/8 to 1/4 turn at a time and recheck the tension each time.
4. Once the tension is good, tighten the axle and brake anchor bolt. Test run the scooter. Readjust as needed.

Check to see if the chain is moving when you apply throttle. If the chain is not moving but you can hear the motor working then it is likely the chain has come off the motor sprocket. If this is the case then follow the steps in the user manual to refit the chain and adjust the tension.

The brake adjustment is covered on page 5 of the user manual. There are photos of various band brakes here http://www.electricscooterparts.com/bandbrakes.html
What part of the band brake are you having and issue with?

Razor E300... | Answered on Oct 27, 2014


Sounds like the throttle is stuck in the full position. Can you adjust the throttle to other positions ? There should be a spring to return the throttle to a "off" position - and then you will have to twist to make it go. The spring may be missing.

The cable may need to be adjusted, or the carburetor needs to be adjusted.

Razor MX350 DIRT... | Answered on Oct 15, 2014


I just did this a couple hours ago. taking off back tire will not help you. The rotor is attached to the wheel itself. You need to line up the hole in the rotor with the valve stem. You will need to have a screw on extension to valve stem ( I got lucky and had one). Screw the extension onto the valve stem then use air compressor to air up the tire.
