Answer 1

I wish folks wouldn't answer stuff if they don't know what they're talking about.

First, if there is a significant difference in the sprocket size (46 vs. 55) that should tell you they are for completely different scooters.  Hub sizes are going to be different, hub widths will be different, chain drive offsets will be different, and on and on.  What you need to do is remove the tire from that rim and put the new tire on your existing rim.  If your rim is damaged and you're wanting to replace it, you need to find one that fits your scooter.

Second, it is possible to change sprockets among similar models, however you cannot drill holes in one sprocket to make it fit another.  Those sprockets are made of a hardened material that cannot be drilled by somebody with basic tools.

Third, there is no way that you have enough slack in your chain to be able to swap a 46 for a 55.  That would require a minimum of 9 more links in your chain.

To change the tire you'll need some tire irons (I'd use two) to pry the deflated tire bead off the rim.  As you work your way around, it'll get more difficult to work the bead over, try pinching the opposite side of the tire down into the "drop zone" in the center of the rim.  If you're doing this on the floor, put your knees on the tire to pinch it down and push inward towards the rim to pry off the other side.

My advise is not to buy ANYTHING to do with pocket bikes. Buy a proper bike and learn real bike control.

Pocket / mini bikes are just for kids.

Answer 3

there is prob enough slack in the chain to use the larger...it will give you a lower gear ratio...if the hubs are the same you can just change the sprocket...get to work...your waisting riding time!!

Answer 4

Sorry, just to correct you, they are called teeth, no big deal though.

Sprockets are usually held onto the hub by 4 bolts. You can unbolt the sprockets easily to replace them.

If they wont fit, you can either drill more holes in your sprocket to make it fit, or add some links to your chain, or buy a longer chain.

55 tooth sprocket will make your scooter a bit quicker off the mark. It will reduce the top speed a bit.

BTW, maybe you could ask the person who is selling the wheel if they have a rear sprocket with less teeth on it?
