I have a friend who has his Dad's Cushman. A '51 step through or bath tub model like yours. We rode it at Fort Meade SD growing up. My first motorcycle ride. That thing went pretty good for it's age. It had a two bar rail around the bottom of the bath tub. Like a protector bumper. The throttle was backwards. You turned it forward. It had a kick pedal to start it in front of the engine. I liked it. His Dad dated his mother with it. They both have passed away now, but the Cushman is still around. I think Sturgis has a national Cushman meet every summer. Different strokes for different folks. Thanks for posting, John
