Start with the frame. Check the welds, replace any cracked parts. Strip the bike of anything that weighs it down – drop a heavy seat, use a thin tire. Refit a strong chain and replace the gears if they’re slipping. Fix the brakes so you don’t skid. Then paint it a dark color and keep the headlight low‑power to avoid attracting cops. You’re not a thief, you’re just fixing a bike to move fast. Done.

If the cops see it, the paint won’t matter if the bike is built for speed and you’re ready to jump the barricades. Trim the frame, keep it light, use a quick‑release wheel. Keep a spare tire in the trunk, know a shortcut off the main road, and be ready to ditch it before the sirens start. No flashy tricks, just a good ride and a clean exit.
