Before you startGeneral guidance from our members' experience, checked against the sources listed at the foot of this page. Old bicycles vary, so check everything against your own bike. Brakes, steering, wheels and tyres are safety-critical: if you're not sure, have a qualified mechanic do or check the work. Any work you do is at your own risk. See our terms.
Not every cheap vintage bicycle is worth restoring. A bad frame takes the same time and materials as a good one, but only one of them is worth something at the end. Use this checklist when you view or collect a bike.
Good signs
- Frame lugs or joints intact, with no cracks
- Wheels spin true (a small wobble is fine)
- Original or matching parts
- A readable frame number
- Surface rust only, with no deep pitting
- Transfers present, even if worn
- Headset and bottom bracket turn smoothly
Check carefully
- Resprayed: check it thoroughly (see Original paint or respray?)
- Replacement parts: are they the right era?
- Wheels out of true: fixable, but it takes time
- Dents: cosmetic, or in a tube that takes load?
- Seized bolts: penetrating oil often frees them
- Damaged saddle: can you get a replacement?
- Perished tyres: a routine replacement
Walk away
- A cracked tube or lug: don't ride it. Any repair is a specialist frame builder's job, if it can be done at all
- A bent or kinked frame: straightening is specialist work and isn't always possible
- Heavy rust you suspect inside the tubes
- A damaged dropout
- Stripped bottom bracket threads: a specialist repair
- Bent fork blades: safety-critical, don't ride it
- No frame number, and a seller who can't explain where it came from
Check the frame is straight
- Sight down the frame from behindStand behind the saddle and look forward. The rear wheel should track directly behind the front wheel.
- Look at the rear dropoutsThey should look parallel. A steel rule laid across them gives a rough check; a frame builder has proper alignment tools.
- Check the forkWith the front wheel out, look down the fork from above. Both blades should be parallel and the same length.
- Test ride somewhere safe, if you canA bent frame often pulls to one side.
Ask before you pay
- Where has it been stored? A damp shed or garage means checking for rust inside the tubes.
- Has it been resprayed or modified? A yes isn't a deal-breaker, but it changes the value and the restoration.
- Is there any history: a receipt, service records or a catalogue reference?
- What's missing? A saddle or mudguard is easy. An unusual hub or headset can mean a long parts search.
- Check the frame number on BikeRegister's free BikeChecker before you pay. It only finds bikes whose owners registered them.

|---|---|
| 6–7 greens | A strong candidate. |
| 3–5 greens | Possible. The price should reflect the work. |
