"The Torpedo is easily the best-handling tandem I’ve ever ridden. Part of the great handling owes to the advantage the PeriScope offers by keeping the stoker’s center of gravity as low as possible. I mean, it also helps that my stoker weighs a whopping 46 lbs, but regardless, the Torpedo carves turns in a way no other tandem I’ve ridden does." Patrick B.
