Buying a used bike can save you some money, but you just want to be weary of some common pitfalls that can make a used bike more trouble than it’s worth.
Here’s the shortlist that I’d ask anyone:
- Why are you selling the bike?
- Any problems that I should know about?
- Is there excess play or strange noises in the suspension fork?
- Are there any issues with any bearings, the drivetrain, or brakes?
If they answer those satisfactorily, it’s probably worth checking out the bike.
Here’s my full checklist:
- Frame size. Make sure the bike fits you well! A decent bike that fits you well is worth much more than an awesome bike that doesn’t fit you.
- Frame and structural components in good condition – no cracks or big ol dents. Seatpost moves freely.
- Suspension fork issues? Excess play, funny noises, adjustments working properly (rebound, compression, spring preload)
- Wheels working fine? Bearings adjusted properly, in true (nice n round), no flat spots or dents, spoke tension good
- Drivetrain in good order? Chain not excessively worn, chainrings and cassette in good order, shifting works smoothly, no chain skipping under load.
- Bottom bracket and crankset in good condition? Has a crankarm or pedal ever fallen off (very bad if it has), bearings good? Pedal threads good?
- Brakes working nicely? Easy lever pull, good braking power, pads in good condition, no squealing.
- Headset bearings are smooth and un-pitted.
- Tires in good condition? No tears, wobbles, plenty of tread left.
- All cables operate smoothly
- The paintjob brings out your eyes
