Hey scooter owners, if you need to replace those wheel nuts on your M365 PRO, this set has got you covered! These steel alloy nuts are seriously durable with great toughness and high strength - way better than cheap alternatives that might strip or break. Each package comes with 2 nuts and 2 gaskets, so you've got everything you need for a proper replacement. They're about 23x23x10mm in size and weigh around 43 grams, so they're lightweight but still super sturdy. Installation is pretty straightforward - just remove your old damaged nuts and screw these on tight. The enhanced safety factor is huge since loose wheel nuts can be dangerous while riding.
