Choosing a good bike shop or mechanic: 7 criteria that matter

The 7 criteria for a good workshop

1. They diagnose in front of you. A good mechanic shows you the chain on the wear checker, the brake pad thickness, the hub play. No "just trust me".
2. They give you a quote first, separating parts and labour.
3. They don't over-repair. They refuse to swap a cassette that's still serviceable just because they're changing the chain.
4. They know multiple brands and standards, not just what they sell.
5. They explain. A workshop that takes 30 seconds to tell you why a fault occurred creates an independent customer, not a captive one.
6. The timescales they quote are met.
7. They handle e-bikes with the manufacturer's diagnostic tool if they stock electric bikes.

The warning signs

A vague quote "all inclusive", refusal to show you the worn part, pressure to change lots of things at once, or inability to explain what caused the fault. None of these signals alone is a deal-breaker, but if several appear together, you should look elsewhere.

Come in with the upper hand

The best way to avoid over-repair is to know what you're bringing in. If you can say "chain at 0.8% wear, cassette skipping on the middle sprockets", no workshop will sell you anything unnecessary.

AI, your independent diagnosis

Before your appointment, feed your symptom to L'Atelier's mechanic AI. It gives you a neutral opinion on the likely cause and parts involved, so you can compare it against what the shop proposes. You'll spot a fair quote from an inflated one straight away.

That's the habit that ties together this cluster: cost of a bike service, repair timescales, warranty and whether to repair it yourself or not.
