Calm, mechanical clarity on the roadworthiness test, built to keep you turning smoothly through every step instead of stalling at the last one.


A flywheel stores momentum so an engine never stalls between strokes, and that is exactly what we try to do with the inspection: keep you moving evenly from one step to the next, with no jolts and no dead spots.
We take the official requirements and set them turning in a smooth, predictable order, so preparation feels like a steady rhythm rather than a series of sudden efforts.
Each stage flows into the next, so the whole process keeps its momentum instead of stalling between tasks.
Our checklists come from the ordinary things that actually turn cars away, not from a copied-out regulation.
When it is time, we show how to book a slot at a CSDD station so the visit keeps the same easy rhythm.
We believe the roadworthiness test is a health check for your car, and that steady preparation is almost always the difference between a pass and a return trip.
Every guide is kept in step with the current rules, so what you read on Flywheel is what you will meet at the station.
