I can't push the seat back far enough
I'm not sure if I'm just crazy but I was hoping someone can help me with this.
I'm in the market for a new bike and have been test riding a few. It seems like on everything I ride, as well as the old Schwinn I currently have, I can't push the seat back far enough. This is because I feel like I have a lot of weight on my hands and I feel like I'm tipping forward. With the seat farther back, I feel more balanced and like I'm using more of the leg muscles to pedal instead of just doing a knee extension. When I'm pedaling hard up a hill I always end up perched on the back edge of the saddle, when it's already as far back as it goes. It's like the horizontal distance of the seat behind the cranks is too short.
I rode the old Schwinn to the local LBS and they had me try tipping the seat up a little. It felt more balanced that way but I was still hanging over the rear edge of the saddle.
What would account for this? Is it seat tube angle or are there other things that affect it? I'm told I have a long inseam for someone my height, could this affect it? Do I just not know how to ride a bike?
Can anyone recommend a bike to consider with this issue in mind? I've been looking at the Cross_Check/Crossrip/Space_Horse style of bikes.
