I'm 54 years old and haven't installed a bicycle tire since I was 12! My husband admitted that he has never done it in his life. So when my well used 7 year old Dogger ran over something at the park and I had to get a new tire, I was dreading having to change it. But to my surprise it took me LITERALLY LESS THAN ONE MINUTE!!! I couldn't believe it!!! We were ready to go to the park in no time! I told my husband how quick it was and he didn't believe me so I pushed one button and took it off. Then pushed the button again to push it back on! His eyes widened and he said, "Wow! They designed this really well!". Thank you Dog Quality. Thank you for your thoughtful engineering!! My Dogger is just as nice as when we bought it. A little wear on the tires but not much. It it wasn't for us running over something that put a fast leak hole in our tires I wouldn't have even needed this part. We love our Dogger and it was such a good investment! Thank you!!
