Marker devices are disclosed in the form of reflex reflectors or the like, for attachment to the spokes of bicycle wheels or the like. In several embodiments, the marker device includes a marker member having seat means for receiving one of the spokes, so that the marker member will be maintained in the desired orientation by the spoke. The marker member is preferably supplied with clamping means for clamping the seat means against the spoke. The length of the marker member is preferably at least twice the spacing between the adjacent spokes, so that the position of the marker member will be stabilized by engagement with the adjacent spokes on both sides of the spoke to which the marker member is secured. The seat means may comprise a groove, formed in the marker member, for receiving the spoke. The seat means may also comprise one or more wall elements on the marker member. In certain embodiments, the clamping means includes a clamping screw which is engageable with the spoke. In certain embodiments, the marker member comprises a pair of reflex reflector plates secured together back to back. In certain other embodiments, the clamping means may include a rotatable cam or eccentric, operable by a screw driver or a lever. In another embodiment, the clamping means may take the form of a wedge block, slidable into a locking position on the marker member.
