I like the white seat you have now.Think it looks the best out of all those options.Why the change? IMHO I feel the pink seat is just too much pink, girls bike or not. I would not add any more pink to your bike its gonna start being too overpowering.
Honestly I think the white seat looks the best then the pink. The grey doesnt look like it blends onto what you have going with the color designs looks like an afterthought. Cool bike nice designs.
love the white thats on it now, the pink with the grey piping looks great also, If i went with the grey it would not have the studs and would have some pink piping
