Onix Tools & Resources
What to look for when buying a used Onix
When buying any used Onix, start with the basics. Check the frame for cracks, dents, or damage, especially around the head tube, bottom bracket, and dropout areas. Look at the drivetrain for wear and make sure the gears shift cleanly through the full range.
Ask the seller for service history and proof of ownership. Every Onix listed on Cyclesite is automatically checked against UK stolen-bike databases, but it is always worth checking the frame number yourself too.
