There used to be a great bike rental shop on the island, Isla Bicycletta, but they went out of business after Wilma. Now it's tough to find a decent one.
My wife and I rented cruisers from Sombrero (Scooter and bike Rentals in Cozumel Mexico) a couple weeks ago. We paid $10/day per bike (we had them for six days). Rogelio, the owner, was very responsive via email and had the bikes waiting for us when we arrived. The shop primarily rents motor scooter and didn't have many bikes, but the ones we had were far from new, but in good repair. The each came with a basket and lock.
