Rear tire of Razor Pocket Mod - Betty is flat and won't hold air. Concerned about removing the tire and trying to replace the tube (as done on front tire several times) because of the gears, brakes, etc.

remove seat then remove four screws on compartment underneath, then unclip battery and remove

it opens from the rear and flips forward

Most likely a bad battery. Check out put voltage on all posts. If it's 12 Volts DC or more, then it should be ok, and you'll need to start looking in the wiring such as the speed control switch. If not, your problem is a bad battery cell and you should replace it. NEVER TRY TO SERVICE A BATTERY!!!!!

check it with a multimeter and make sure that its putting out the correct amount of volts, it should be at least 24 volts

Hi,
It sounds like you have to replace the electric motor. Good luck!

just about any motorcycle shop will change that for you for a small fee, I'm curious why you got a tube? Most motorcycles use tubeless tires now,

Use a wedge. Place the thin end between the tire and rim. Then push the tire off using the wedge and your other hand, work your way around the circumference of the tire until it is off. Use the same process to put the new tire on. But this time you will push the tire on the rim.
This is a pic of the ideal tool you should use:

Hi
Deflate the tire and then you can gently move the valve to a straight up position. Now refill the tube.

Replacing the rear tire is a real nightmare.....you are much better off purchasing the entire rear wheel assembly which you can do from the Australian distributors Funtastic for only about $10-$15 more than if you just bought the tire.

To replace the tire you need to use a bench vice which a couple of bolts clamped into it to hold the hub in place.....you then need to remove the sprocket assembly which is a reverse thread......i had to use a hammer and a large flat head screw driver wrapped in a rag so as not to tear up the teeth.

Once you've loosened the sprocket assembly you have to undo the bolts the hold the two sides of the wheel together and the tire will come right off.

All of this would be totally unecessary if they used a tire that you could remove just like any other mini motorcycle tire.

They don;t and so it is what it is.

As I said, next time just buy the whole assemble and then it's very straight forward.

Hope that helps!
