The design is nifty, but not quite what we're looking for. It looks more like a badge than a wheel. Can you make the heart more prominent and factor in the dual pipes? The use of two fonts is great.
#26 feels a little better visually balanced, with the black inside of the heart. I was trying to make it almost feel like a heart-shaped wheel behind the wordmark.
Also, I've been thinking how awesome this could look on t-shirts or other things, especially with a grunge vintage look. So, I also mocked up a flat color version, which shows exactly how it could look if screenprinted onto shirts or other apparel: #27
