Edit lib/ionic/css/ionic.css and remove/comment out the conflicting style attributes for input[range] Keep in mind that you will have to replicate the change in ionic.min.css for prod builds and/or if you update the ionic framework. Obviously you will have to come up with something less blunt if you are using or planning on using the Ionic framework's range input control styles.
