Made of high-quality sponge, durable, soft, and comfortable to ride. Bike handlebar grips are ergonomically designed to provide a secure hold, even during extended use, offering a soft and comfortable feel for both adults and children. Suitable for handlebars on bikes, cruisers, e-bikes, folding bikes, racing bikes, mountain bikes, tricycles, pedal bikes, and children's low-speed bikes. The grips perform well in extreme hot weather without melting, fading, or leaving residue. Caution: Apply a small amount of soapy water, detergent water, or car wax on the grips as a lubricant during installation. Avoid forcing the grips onto the handlebar too tightly, as excessive pressure may cause damage due to friction.
