K&H Pet Products Universal Pet Travel Rear Bike Mount Black Universal Fit

I bought the rear mount because I have a road bike and wanted to take my cat on cycling adventures. Mounting the basket to the front of my bike just wouldn't work for my needs because the basket is too big, and I have brake lever shifters so that's why I picked rear mount. It works great for my 14-pound kitty, but I did make a small modification to make the setup sturdier. It seems like there needs to be more than just the 7-inch metal piece that slides into the basket plastic device to hold it into place. It felt loose/flimsy and not secure. So, I ended up using the straps that would be hooked onto the handlebars and weaved those to the underside of my seat to secure the basket so it wouldn't move around. Otherwise, it's too wobbly for my liking. That adjustment works so far for us, it feels 100% more secure but we have only been on one ride so far.
