I ride a 24 inch Magicycle Ocelot Pro Model. It came with Kendra knobbies which may be better on dirt, gravel, chat or sand, but I PREFER Asphalt Paved Trails or Streets or Concrete. These tires roll farther, Faster and Quieter using the same energy. Which means you can travel farther using less energy.... The Silence and smooth ride is an added benefit. I ordered 2 with inner tubes and installed them myself. A bargain and worthwhile improvement. I have videos to share.
