You didn't say where you would be renting in TV, it's 15 miles from the bottom to the top. In the newer areas Villages Cycles at Brownwood, located between MVP Gym and McAlister's Deli rents bikes. They also have a Spanish Springs location in the Belk's Shopping Center off of Bichara. If you're in the very northern ends such as Chatham or Calumet Grove, best bet would be to park your car at the Belk's shopping center and rent from that location. Here's a link to their website.
