you need the mach bike. that is the fast bike.
all you need to do is to get over those weak tiles really fast, that means you have to pick up some speed before you even get on the weak cracked tiles. not only that you also have to make your turns right before you collide into a wall. colliding means losing speed and that means you fall through the crack floors.
if you are playing this on a PC, you can set the emulator to run the game at a slower speed, so you pretty much see things happening at half speed if you want. myself i have done this at full speed just like any other player using the real GBA, it is possible.
