1. A wheel for use with a bicycle, the wheel comprising: a hub for mounting the wheel to a bicycle;a rim about which a tire is mountable; anda plurality of spokes extending between the hub and the rim,wherein the rim has a radially inner edge, and wherein at least part of the radially inner edge has an undulating configuration and a radial distance that continuously varies between adjacent peaks and troughs of the undulating configuration, each peak of the undulating configuration having a convex exterior profile in a plane of the wheel. 2. A wheel as claimed in claim 1, wherein the undulating configuration is arranged along a circumference of the radially inner edge, such that the radially inner edge is either intermittently undulating or continually undulating. 3. A wheel as claimed in claim 1, wherein the radially inner edge is continually undulating. 4. A wheel as claimed in claim 3, wherein the radially inner edge comprises a series of alternating concave and convex regions positioned immediately adjacent to each other. 5. A wheel as claimed in claim 1, wherein the rim comprises side surfaces which are configured such that the radially inner edge is defined by rounded inner portions of the side surfaces. 6. A wheel as claimed in claim 1, wherein the radially inner edge has an arrangement of undulations arranged along the full extent of the radially inner edge. 7. A wheel as claimed in claim 1, wherein the undulating configuration defines a series of undulations located between points of connection of the radially inner edge and the spokes. 8. A wheel as claimed in claim 1, wherein the undulating configuration defines support elevations located in the region of connection of each spoke with the radially inner edge, and at least one ancillary elevation located between adjacent spoke connections. 9. A wheel as claimed in claim 1, wherein at least twenty-four pairs of peaks and troughs are provided along the radially inner edge of the rim. 10. A wheel as claimed in claim 1, wherein the difference in radial height between the peaks and troughs of the undulations is at least 10 mm. 11. A wheel as claimed in claim 10, wherein the difference in radial height between the peaks and troughs of the undulations is at least 20 mm. 12. A wheel as claimed in claim 1, wherein the rim is made of a composite material. 13. A wheel as claimed in claim 1, wherein the rim has side surfaces that curve laterally outwards from the base of the rim, and then curve laterally inwards, before meeting at the radially inner edge of the rim. 14. A wheel as claimed in claim 1, wherein the rim has side surfaces that meet at the radially inner edge of the rim, an exterior cross-sectional profile of the side surfaces at the radial inner edge of the rim having a radius of at least 5 mm. 15. A wheel as claimed in claim 1, wherein the exterior cross-sectional profile of the side surfaces at the radial inner edge of the rim has a radius of at least 10 mm. 16. A wheel as claimed in claim 1, wherein the radially inner edge of the rim is rounded. 17. A wheel for use with a bicycle, the wheel comprising: a hub for mounting the wheel to a bicycle;a rim about which a tire is mountable, the rim having a radially inner edge and side surfaces meeting at the radially inner edge;a plurality of spokes extending between the hub and the rim; andwherein at least part of the radially inner edge has an undulating configuration and a radial distance that continuously varies between adjacent peaks and troughs of the undulating configuration, and wherein an exterior cross-sectional profile of the side surfaces at the radial inner edge of the rim has a radius of at least 5 mm. 18. A wheel as claimed in claim 17, wherein a radial distance that varies between peaks and troughs of the undulating configuration and the difference in radial height between the peaks and troughs of the undulations is at least 5 mm. 19. A wheel as claimed in claim 17, wherein the rim is made of a composite material. 20. A wheel as claimed in claim 17, wherein the rim has side surfaces that curve laterally outwards from the base of the rim, and then curve laterally inwards, before meeting at the radially inner edge of the rim. 21. A wheel as claimed in claim 17, wherein the exterior cross-sectional profile of the side surfaces at the radial inner edge of the rim has a radius of at least 10 mm. 22. A wheel as claimed in claim 17, wherein at least twenty-four pairs of peaks and troughs are provided along the radially inner edge of the rim.
