My razor mx 500 motor won't turn.
I think you are talking about an electric motor on your bike . If the motor is New you may have a bad throttle switch . You can use an ohm meter to check the throttle switch . Connect the two leads of the ohm meter to the wires of the throttle switch ( dissconected) . As you turn the throttle the ohm reading should coraspond to how much you turn it .
Rear wheel sprocket turns with chain, but doesn't
BEST SOLUTION GO TO A GOODWILL MOST OF THE TIME THEY HAVE-
BIKES FROM $10.00 TO $40.00 AND YOU LOOK FOR A BIKE
THAT HAS A GOOD BACK WHEEL AND YOU'LL HAVE EXTRA
PARTS HERE IS A LIST OF PLACES GOODWILL&THRIFT STORE&
SWOPMEET THAT HOW I FIX MY BIKES..
HAPPY HUNTING.

Razor MX500 not working...clueless Mom trying to
Either the cheap lead acid batteries are near dead (mostly due to improper maintainance (lead batteries are way too much trouble and lithium should be considered!)
There could be a loose or corroded connection - check on all your wiring, especially the ones to the motor.
Also where it goes into the motor is fragile and people bump that area and it rips the wire, there is a steel spring that surroiunds the wire/s and this sometimes shorts out because of the damaged cause from laying the bike on it's side. check these wires over and tug on the connector wires to find the weak connection. Also verify that your charger turns red indicating it is charging when attempting to charge the bike, if it stays green chances are a dead battery or BMS controller inside battery (Lithium only!)\
Most repairs are very simple if you take the time to check out the connectors and wiring, especially if you use it in bad weather, things get corroded from being wet and power shorts out then corrodes the wires and connectors.
Good to insulate them for the rain etc...
Think Im on the right track here, and i have many ebike because people dont know how to fix simple issues with a tester.
Son left e300 out in rainstorm and wont start, no
You don't say what brand e300, buy the connections are corroded. Doesn't matter how good it was taken care of previously. Being left out in the rain is all it took. This is why electronic devices TELL YOU to not expose them to moisture...
No telling which circuit board is fried, but if you solder, you can replace them one by one to find out.
But TBBH, for the time, aggravation, and cost, just go buy a new one if the original cost anything under $100.
If you paid more than $100 for it, call your local RC shop and ask who does repairs.
Could be your rotors (most likely - copper rusts by breathing on it), or a board connection. Rotors are not hard to replace if you can solder.
JMO, but if it is of value, always supervise kids when you let them "PLAY" with it...But hopefully, lesson learned all around. Best of success to you.

I have a mx400 razor.
DOES THE BIKE HAVE A FUSE CONNECTION BEFORE THE
CONTROLLER? IF IT DOES THEN I WOULD LOOK FOR THE
FUSE LINE AND IF IT DON'T THEN I AGREE WITH YOU'R
ASSUMPTION.IF AND WHEN YOU DECIDE TO FIX IT,I WOULD CONSIDER A FUSE I'LL BE LESS $$$.

The bike only goes like 2 miles an hour how can I fix this
this is a little complicated.
1-check fuel line and filter make sure you have a good gas flow.
2-check you'r hose's for leaks 3- OPTIONAL -check you'r engine for
compression.you can buy a pressure gauge at auto zone
buy the one that screws into the piston hole it makes it
easy for you.
REMINDER!! IF CHECKING THE FUEL LINE AND IF IT RUNS BETTER OR BY CHECKING THE HOSE'S AND IF IT RUNS BETTER (THEN YOU WON'T HAVE TO CHECK ENGINE
CHECKUP THIS OPTIONAL.) SAFETY FIRST GOOD LUCK.
