You don´t see as many bikes in daily traffic as in other European cities, but for leisure the Portuguese love to ride bikes.
In the weekends the roads are full of race bikes and the downhill scene is steadily growing. There are not many official trails, but around Lisbon you can find some secret man made ones. If you know who to ask.
There are no big mountains around Peniche, but the cliffs along the north coast has a beautiful cross country trail. Starting in Baleal, via Almagreira and the golf resort in Praia d’el Rey you can make your way all the way up to the lagoon of Obidos. You can see Rico and Sebbo there every week. You don’t need a full suspension bike for the trip, a solid hard tail should do the job. Enjoy the view.
With a street bike, or even with the beach cruiser you can explore the area behind Baleal.
At our apartments and at the hostel there are some free to use bikes for our guests.
