East Bay - Berkeley to Lake Chabot via Grizzly Peak Blvd

Planning an East Bay ride from North Berkeley BART station up over Grizzly Peak down the East Bay Ridges via Grizzly Peak Blvd, Skyline Blvd, Pinehurst Rd and Redwood Rd to Lake Chabot Park...It is about 25 mi one way over very scenic winding park roads with little residential areas and no major highways...Google Maps says it is about an hour by car over this route so I would guess about 1.5 hour of scooter time...It should be very scenic and twisty if it is anything like the Grizzly Peak Summit which I have ridden...The return route would be open based on time available but one option is back up through Orinda and the San Pablo Dam road....If anyone is interested we can meet at the North Berkeley BART station at a time that is convenient on Sat morning Aug 9th...
