In spite of (or maybe because of) the local enthusiasm for cycling, there is a real shortage of places to hire bikes. The motorbike shop outside the San Francesco gate sells, but does not hire out, secondhand push bikes. The closest cycle hire we have been able to find is
La Maglia Rosa Bikeshop
Via Francesco Paolo Tosti, 166
Francavilla al Mare
tel 085 4914384
lamagliarosa@micso.net
This is 8 miles south of Pescara - you would either need transport to Penne or allow a day to cycle back.
