Where there is blame there is a claim. Im think you can use CTC and BC lawyers for such things. You would just take the same path as a car driver would in this situation. Type of transport does not make a difference. If everyone claimed for damage they may fix the potholes.
If any claim is made I would think it would be like for like.

Some cases involve incidents that have occurred along a highway, as a result of a bicycle wheel hitting a pothole or other defect in the road. In these cases there is clearly no Third Party involved, and there are unlikely to be independent witnesses to the incident itself. The Highways Act 1980 imposes upon a Highway Authority a duty to maintain a public highway. The fact that an incident has occurred owing to the poor condition of the highway might, at first glance, be thought to be sufficient evidence to prove that the Local Authority were negligent for failing to maintain the highway in a good condition.
However, it is very important to be aware that the Courts have been careful to qualify liability to prevent Local Authorities from effectively being the insurer of all highways users who suffer incidents from minor defects.
In fact, a statutory defence is available to a Highway Authority if it can be proved that the authority has taken all reasonable steps to maintain the highway to the standard necessary to accommodate the ordinary traffic that passes along it. Photographic evidence of the defect is crucial, as it is common for defects to be repaired
once an incident has been reported, leaving no evidence of the defect should liability be disputed by the Local Authority. In addition, where possible, measurements of the pothole or defect in the highway should be obtained and an exact description of the location of the defect provided.
