Sounds like you had a wonderful day.

There are loads of places up here on the NE coast worth a visit and Robin Hood's Bay is great. Further up past Whitby are Sandsend, Runswick Bay, Port Mulgrave, Staithes, Saltburn - all worth a visit.

Whitby was always High on my list off rides out,

the moors road from Guisborough

and back the coast road to Redcar.
did you go down to the bay with your bike or is the road closed now?
I also liked going to Staithes in the off season, there is a nice little harbour and a nice little Pub there,

ahh the good old days, but I can not complain Austria is also great but no seaside
