We always take our own, so I don't know for sure, but according to the info I have, bikes rent for about $15 a day (till 5 p.m.) or about $7 an hour. If I recall correctly, kids must wear helmets and they are provided.
Here is the bike barn #, you may want to double check this info or see if they rent for longer periods of time--407-824-2742.
