I’ve enjoyed both Wet Beaver Creek and West Clear Creek, both convenient to I-17. West Clear Creek has many wonderful swimming holes. West Fork north of Sedona is another favorite. Hikes near Flagstaff offer higher elevation, cooler summer options.
I personally would have to say no. You see a lot of off road vehicles using the roads and trails but biking might be difficult. There's open space to explore on foot but I did't see any specific hiking trails
