im just wondering, how come recumbent bikes dont have headrests? i build/ride wooden streetluge and classic luge. we lie flat on our backs, and have to hold or heads up. holding my head up on the classic luge (no head rest allowed) after about 1 mile my neck is killing me, especially with the weight of a full faced motorcyle helmet on my head. i know bicycle helmets are light, but dont your necks get tired? just wondering, fast eddie outty
