If you're in the area, Ring of Gullion Cycle Tours is definitely worth a visit. The rental shop here has everything you need for a trip - whether you're just looking to rent a bike for a few hours or plan a longer tour through the scenic Ring of Gullion landscape. It's especially handy that they also offer repairs and spare parts if your own bike needs a little rest.
I noticed that the equipment was well looked after and the staff were friendly. They took the time to give me some tips on the best routes in the area. The proximity to the main road and hiking trails is a definite plus, especially if you're travelling with children - as I was. The trailer offer for the little ones is a great option for taking the whole family along.
The facility itself isn't exactly a highlight, but it does the job. Perhaps a small covered area for the bikes would be a good addition to be better prepared in inclement weather. Nevertheless, for a spontaneous bike tour or a small repair in between, this rental is just the right thing.
