We rented two mountain bikes from them for a week while in bonaire. We put them to some use, on a long ride in the national park (21 miles) and on shorter ones through the donkey sanctuary, and even off trail along the east coast on the blue trail. They held up well, shifted consistently and were great. Only thing missing was a bag and bottle holder for one bike, but we had a backpack with us so this wasn't a big deal. They delivered on time and paperwork was easy.
