We stayed in Adeje and rented bikes form a big sporting complex there. Seemed decent prices for very good bikes(Supersix Evo, Shimano Ultegra, Mavic wheels). We tacked Teide via Chio and returned via Villafor and Las Americas. Was a longer and easier way up…about 56km to climb to the summit from our hotel at sea level on the coast, and 30km back from the summit, so an awesome descent which is the way i’d recommend if you’re that side of the island. But either way it’s a pretty brutal climb – seal level to 2,100m non stop climb…not many climbs in the Alps can top that. Had a cracking day.
We rented a car and went around the opposite end of the island for a day to the Santa Cruz side and came home over the top of Teide….that looked like a brutal way to get upto the top of Teide by bike. You’d better have your climbing game on if you go up that way. Didn’t pass many cyclists heading up that way.
