They're easy to assemble, simple to load, and gentle on your bike, there's little risk of scratching paint or damaging rims. Adjusting for different wheel sizes is just as easy. It is strong well built and sturdy. When not in use! It is as simple as attaching it on and detaching it with ease to store for the next ride with my 6 year old boy. I love it my son loves it and he loves helping me strap down our wheels everytime we take our bikes out. Thanks Team. I will spread the love around with my friends and family if they're in need of a bike rack and where to purchase one from ??
