Accessories
Browse used cycling accessories for sale from riders across the UK. The category covers bike accessories such as lights, locks, mudguards, pumps and racks, along with cameras, electronics including computers, power meters and turbo trainers, and personal care items. These are the parts riders change most often, which is why they come up second-hand in such volume.
What counts as a cycling accessory?
Anything you add to the bike or carry with you rather than build into it. Bike accessories covers the physical fittings — lighting, locks, luggage, bottle cages, mudguards and track pumps. Electronics covers head units, heart rate monitors, power meters, smart trainers and radar units. Cameras covers action and handlebar-mounted cameras and their mounts. Personal care covers chamois cream, sun protection and the like. The dividing line from components is whether removing it stops the bike working: a light does not, a chainring does.
Accessories or workshop tools?
Accessories go out on the ride; workshop items stay at home. A mini pump and a multitool live in a jersey pocket and belong here, while a repair stand, torque wrench and chain whip belong with workshop equipment. The overlap is in things like track pumps and chain lube, which sit on the workshop floor but are usually shopped for alongside other accessories. If you are kitting out a bench rather than a bike, look at workshop tools first.
What should I check on used lights, locks and electronics?
Batteries decide most of it. Rechargeable lights and head units use lithium cells that lose capacity with age regardless of use, so ask for a realistic runtime rather than the figure on the box, and check the charging port for corrosion and bent pins — a common failure on units that have been ridden in the rain. On locks, confirm every key is present and that the barrel turns smoothly, since replacement keys are often impossible to source and a stiff barrel is a sign of internal corrosion. On computers and cameras, check the screen for delamination and the case seals for splits. On turbo trainers, listen for bearing rumble and confirm the firmware still updates. Mounts and cradles break at the tabs, so check those rather than assuming they are included.
When should I buy accessories new instead?
Buy new for anything where a failure ruins the ride or the item — locks in particular, since a used lock's security history is unknown and modern designs resist attacks that older ones do not. Battery-powered items are the other case: a light or head unit more than a few years old may hold half its original charge, and cells are rarely replaceable. Used works best for durable, mechanical accessories — racks, cages, mudguards, track pumps, tool kits — which have little to go wrong and often sell at a third of new. Power meters and smart trainers sit in between: high value, mechanically simple, but worth confirming the unit still pairs and calibrates before you pay. Sellers across electric, city and BMX categories often list accessories alongside the bike they came off.
