Hiboy Max Pro Flat Repair

How to fix a flat on the rear tire of a Hiboy Max Pro

(I will likely make another video showing the whole process more clearly the next time I get a flat)

But here are my written instructions:

(Most of this will become clearer when you are actually doing it)

Take off the orange stickers and remove the plastic pieces that cover the wheel nut using 4mm Allen wrench.

Remove the wheel nuts

Remove the washers with the tabs.

Slide the wheel assembly out of the frame

Look out for the washer that is a spacer on the right side axle

Remove the wheel ring on the right side. 6 screws that are 4mm Allen wrench.

Pull out the drum brake from the hub. It just slides out. No tools. Don’t undo the cable or anything. Just let it hang there while you work.

Pull the ring on the right side off. It doesn’t come all the way off because of the motor wiring. That’s ok.

Take the nut off the valve stem and push the valve stem through the hole in the rim.

Pull both the tire and tube off the right side of the rim. Again they don’t come all the way off because of the motor wiring. That’s ok.

Now pull the tube out of the tire and the pull it over the hub and off the left side of the wheel. It will work. It’s just a pain. Note: You can take both the tube and the tire off the left side of the hub pretty easily. It’s probably easier to do that.

Now you have your tube out all the way.

Now put the new tube in over the left side of the wheel. Pull through the tire.

Make sure the valve stem is in the right place to go through the hole in the rim.

Put it through the hole. Put the nut on the valve if that’s the type of tube you’re using.

Shove the tube into the tire.

Push the tire and the tube back onto the rim. This isn’t easy. Just keep at it until you get it.

Then put the ring back onto the rim and hold it all together.

Put the screw back to fasten the ring to the wheel.

Now the wheel, tire, and tube should all be where they need to be.

You can inflate the tire now.

Put the washer/spacer back on the axle on the right side.

Slide the brake assembly back where it goes on the left side.

Slide the wheel back into the frame.

There is a channel on the brake drum that has to slide in the right way. Look at it. You'll see how it goes.

Put the washers with the tabs back on.

Out the nuts back on and tighten with 17mm wrench.

Then put the plastic covers back on.

Deflate the tube completely. Then re inflate it to 35-40 psi.

You're done.
