I have just seen and enlarged a photo of a 1978 cruiser with hub lockers on both front and rear axels. Excuse me if I am ignorant...is this possible and would that mean it can be locked on all fours that way, would the axel be different. Is this nuts...'cause it sure looks like a locking hub sticking out the rear wheel as far as the front. Any thoughts here. Thanks in advance O wise ones.
