Only had problem with one ear, other was fine. I dont know how you would get 6 bikes on this rack unless they are kids bikes. It fits my foot great. and easy to Tote around anywhere. I’m 5’2” and weight 130lbs. Just need to play with your music center settings to get the right sound u want. They are so soft and almost a perfect length for me. These are great pants for all weather, including summer. Cheap and fast worth it! I’m planning to wear it as a necklace (last pic)❤️❤️
