I couldn't say the aperture for sure (as this was shot with a dumb adapter), but my best guess would be at f/2 or f/2.8.
The rest of the settings can be seen on the EXIF info (over at the flickr page), at that says that the speed was 1/400, at ISO 100.
Love your style @35mm . I don't know how to even describe it but words that come to mind...tranquil...calming....I dunno. The bike directly above is just brilliant 👍
