Bike Riding Should Be Enjoyable. Usually the original bicycle seat cushion is very hard and narrow, so that we always feel uncomfortable or painful when riding. Therefore, Zacro designed this comfortable bicycle cushion cover. Our bicycle seat cover provides an ultra-wide size (11.0*10.2 inch). This gel bike seat cover is softer and more comfortable than ordinary saddles to help you ride on uneven terrain . The bicycle saddle cover comes with a waterproof cover so that you don’t have to worry about getting the cushion wet even in rainy weather. This bicycle seat cover is suitable for most indoor exercise bike, mountain bikes and is easy to install.
