Good bike and helmet selection for all ages. Great service. He "fitted" us and made sure my husband and I and all 3 kids had the right size. We had an all day rental but didn't get there until after 12. Told him we still wanted the bikes, but needed to get the kids lunch. He suggested a sandwich shop 2 parking lots down that had great sandwiches (he was right), and said he'd put baskets on our bikes so we could carry lunch and have a picnic (there are shelters and picnic tables all up and down the path). Worked perfectly. He also put locks on all the bikes, should be need them.
By the way, if you're coming from Lihue, as we were, in Kapaa, you will pass a grocery store, Subway and Starbucks in a strip mall on your left just before downtown Kapaa and this shop - you could pick up picnic essentials there, too, before getting to the shop.
Anyway, you just pedal right out of his lot, onto the path. Great family activity. We got to stop and watch some surfers along the way.
The best part - although we'd reserved for all day, and we clearly cost him a morning rental of 5 bikes (they were sold out by the time we got there), he still only charged us for the half day we used them.
When you're done, head just south of his shop on the main drag and go to Hee Fat General Store for the best shave ice on the island (according to the guidebook as well as my 3 kids, who made it their business to sample many places)!
The bike ride was one of our favorite experiences the week we were in Kauai!
