Is your mini bike missing some essential hardware? The M12x1.25 flanged axle nut is a small part that might be easily overlooked until you need to replace it.
This is the fastener that used as the front & rear axle nut on popular mini bikes such as the Coleman RB100 105cc, the Motovox MBX10 and MBX11, the Monster Moto / Mega Moto Classic 80cc (MM-B80), Classic 105cc (MM-B105), Classic 1000w (MM-E1000), and TaoTao DB100 105cc mini bike. The wide flange spreads the compression to the fork.
