- High quality materials and finish The cup holder uses mirror-surfaced chrome-plated aluminum alloy for the body and a high-strength steel for the handle. The smooth surface is easy to clean, corrosion-resistant, and durable. - Multifunctional design for secure and temped drinks Two detachable foam insulation layers inside the cup holder help keep drinks hot or cold. The insulation also fixes small cups so they will not shake or roll over on bumpy roads. A drain hole at the bottom allows water from condensation or overflow to be drained, keeping the inside of the cup holder clean and dry. - Easy installation and removal Includes a portable L double-head screwdriver for quick installation and disassembly anytime, anywhere. - Broad compatibility and size range Suitable for Harley, ATV, UTV, motorcycle, and bike installations. Fits handlebars from 7/8" to 1 1/4" (7/8" = 22 mm; 1" = 25 mm; 1 1/4" = 32 mm). - Practical use scenarios 1) On long highway rides, keeps beverages at stable temperature with dual insulation layers. 2) Off-road or rough terrain on ATV/UTV or motorcycle, the foam layers secure small cups to prevent shaking or spilling. 3) Daily commuting or city riding, the drain hole helps manage condensation or overflow to maintain a clean cup holder interior.
