Ok. So I wanted a dedicated trainer bike. My dad had one laying around from early 2000s. It’s a weird fit but not in a way I thought it would be.
I currently have the seat all the way back and my knees and such seemed to be aligned ok over my toes (tell me if I’m wrong)
But to me it doesn’t make sense that the seat needs to be that far back especially considering the reach is insane, but if I move the seat up I feel like my knees are too far over my toes.
Picture one and two show the seat moved back as far as possible with 6/12 and 3/9 foot positions. My knee seems to be in a good position. Picture three shows if I move the seat forward that puts my knee really far over my foot when pedaling.
Do I just not understand body mechanics? Is the frame on the smaller size for me? (I couldn’t find a size on it) The reach however is pretty far so moving forward would help but I worry it’s not good on my knees and uncomfortable. So not sure what’s my best move here.

IMO your knees are too far back at full extension. Tbh the whole frame looks a little small for you. If you’re on the hoods, this position may cause you to perch excessively on the saddle horn and cause pain. This whole fit will likely cause rocking during your spin. Bike fit is based on being on the hoods at optimal reach. Anything else is a resting position. Also the hoods are too to close/high. They should be close to parallel or just slightly higher than the bar top.
Fix the hoods and slide the saddle forward until your reach is comfortable at 15 degree elbow bend, with your sit bones properly located on the saddle wings, and the rest should work itself out logically.
