If it's a personal injury claim, it's irrelevant that you've had no financial loss, laura - the claim is for your pain and suffering, future prognosis etc. You have three years to initiate a claim, that's three years from the date of the accident. If as you say the cyclist was fully to blame and there is no contributory negligence on your part, then why not try to bring a case for negligence against him? Your insurance company should appoint legal representation for you if you have legal cover either on your motor policy or your household insurance policy. The claim may not succeed, if the cyclist has no funds, but if I were in your position, I would claim.
