ETLIFE Glowing Wheels Aurora Color 68mm [No Batteries Required, Tires

• [Rare 4 light glowing wheel mini size compatible] Compatible wheel with diameter 68mm x thickness 24mm that meets standard specifications. • [Lights without batteries!] A glowing tire made using special technology.It generates electricity based on rotational force and emits light.Therefore, once installed, it can glow without batteries. • [Overwhelming wear resistance with a hardness of 90A] We use a hardness of 90A, which is the most popular in many places such as city riding, neighborhoods, roads, parks, etc.Although higher hardness does not necessarily mean higher wear resistance, we chose 90A, which has a good reputation for wear resistance based on customer feedback.If you want to use it in a dedicated park, we recommend purchasing dedicated wheels. • [Smooth running with ABEC-7 bearings] Bearings are parts that make tires rotate smoothly.Luminous wheels have the disadvantage that the tires are harder to turn than normal because they convert power into electricity.Therefore, ABEC-7 standard bearings are used to support smooth rotation. • [Smaller tires are more stable] Some people choose larger wheels because they are afraid of the tires wearing down, but the larger the tires, the more unstable your feet will be.We strongly recommend choosing 68mm to reduce the risk of falls for beginners and children.
