Gear Ratio Explained — Using LEGO Speed or torque? You can’t get both for free. This LEGO setup clearly shows how gear ratios work: small gears drive fast, large gears drive strong — and every change has a cost. By swapping just a few gears, the entire behavior of the mechanism changes. No equations. No theory overload. Just visible cause and effect. 🎥 Watch the gears closely in the video Which setup would you choose: speed or power? #LEGO #LEGOTechnic #GearRatio #MechanicalPrinciples #Engineer

Your gear ratio is the difference in size between the chainring at the pedals and the cog in the cassette at the rear. Useful for working things out - like speed, or which ratios on a fixie won't result in you always doing skids on the same part of the tyre... #GCN #GCNTech #Maths #GearRatio | Global Cycling Network
