I did one of the night tours, and it was an interesting way to see the city. I'll be honest though, the majority of the fun on the tour is riding the bikes! I enjoyed that the guides were caring and thoughtful when teaching you how to ride the bike as well as during the ride itself. As for the tour, it was a bit more difficult to view things at night - but I still got a good perspective on Austin, and I'd consider doing a similar tour in a different city the next time around.Many thanks to the guides!
