As per the UK Highways Traffic Sign Manual Chapter 3 - Regulatory Signs page: 52 The following advice is given:

5.11.1.  The sign to diagram 951 (S3‑2‑21, see Figure 5-22) should be used to give effect to a prohibition of cycling made under an order or, more often, imposed by a byelaw. It is mainly used where there are pedestrian routes through housing estates which are not suitable for cycling because either their width or the visibility along them is not sufficient. In order to make such areas more accessible, traffic authorities are encouraged to provide suitable facilities for cyclists (see section 11 for the signing of cycle facilities). The sign to diagram 951 should not be used to indicate the end of a shared pedestrian and cycle facility (see 11.11.8). Another use for the sign is where pedal cycles are prohibited from major roads such as a dual carriageways subject to the national speed limit. The sign does not have a supplementary plate.
