Plan to convert your 20" wheelset to a 24"?

If you plan to convert your 20" wheelset to a 24", you will have to note that the difference of 4 inches in wheelsize is too great. You may have a problem fitting the tyres through the fork installed. Even if you change fork to one for 24″ wheelsize, you will face issues with the frame.

As you can see from the image of this frame, the area mark “X” gets narrow towards the seatpost tube.



So, it is likely that the tyres will be touching the sides of the frame once the tube is inflated.

It does not matter if it is a regular bicycle or a folding bike, As you can see from these image of a folding bikes.
 

There is not much clearance space to fit a larger rim even if you remove the mudguard.



Find out how much it will cost you to buy a 24″ wheelsize folding bike. If you consider the cost and service fee to change the rims and replace tyres and tubes, you may want to consider buying new.
