It didn't come from there. The mountain bike came from users, came from young users, particularly a group in Northern California, who were frustrated with traditional racing bikes, which were those sort of bikes that Eddy Merckx rode, or your big brother, and they're very glamorous.
Ide itu bukan dr sana. Ide sepeda gunung datang dari pengguna, datang dari pengguna muda, tepatnya dr sebuah kelompok di California Utara, yg frutrasi dengan sepeda balap tradisional, yg biasanya mirip sepeda yg dipakai Eddy Merckx, atau kakak anda, yang luar biasa mewah.
