Create a motorcycle club logo featuring a fierce skeleton character. The skeleton should be dressed in a leather biker jacket and wielding a large, menacing scythe. Replace the typical grim reaper hood with a spiked helmet and aviator goggles. Add elements like flaming tires or exhaust pipes to highlight the motorcycle theme. The background should include crossed wrenches and a pair of wings extending from behind the skeleton. Use a bold and gritty style with a monochromatic color scheme (preferably black and white) to achieve a classic, rebellious look. Integrate the club name, "Riders of the Abyss," into a banner at the top or bottom of the logo in a rugged, gothic font. Ensure the design is simple and minimalistic, suitable for patches and club branding, and avoid excessive detail to maintain clarity for embroidery. NO TEXT OR WRITING IN THE LOGO
