In this scenario, are you permitted to overtake the bicycle?

Why?

The visible B-25 no-overtaking sign prohibits overtaking motor vehicles with more than one wheel track, so it does not cover bicycles. You may overtake the cyclist riding near the right-hand edge, taking particular care and leaving at least 1 m of lateral clearance. You must not drive onto or cross the solid centre line.
