Few corners of cycling are as confusing as wheel sizes. The same wheel might be called 700c by a road rider, 29er by a mountain biker and 622 by an engineer — and they would all be right. Meanwhile "26-inch", "27.5", "650b" and a tangle of French and inch markings on tyre sidewalls leave plenty of r
Read more →Your gear ratio is the single number that explains why one bike feels effortless on a climb and another feels like wading through treacle on the flat. It is also one of the easiest things to work out yourself: you need nothing more than the ability to count teeth and do a little division. Once you c

The conversion i
Read more →"How far will it go?" is the first question almost everyone asks about an electric conversion, and it's also the one with the most slippery answer. Range isn't a fixed number stamped on the battery; it's the result of how much energy you carry and how fast you spend it, and the spending rate depends
Read more →The mechanical side of a conversion is forgiving; the legal side is not. A kit that is perfectly legal in one country can make you an unregistered, uninsured motorcyclist in another, and a conversion makes it unusually easy to cross that line without noticing. This guide explains the main frameworks
Read more →The bike you start with shapes everything about your conversion: how easy the install is, how well the finished e-bike rides, and how safe it is at speed. A great donor bike makes a kit feel like it was designed for it, while a poor choice means fighting clearance issues, dropout worries and handlin
Read more →How fast you go on a bike is not down to one thing — it is the product of three: how quickly you turn the pedals (cadence), how big a gear you are pushing (gearing), and how far your wheel rolls in one turn (wheel size). Get all three working together and a relaxed-looking spin can carry you along a
Read more →The battery is the heart of any conversion: it is usually the most expensive component, the heaviest, the one with the biggest impact on your range, and the only one that can genuinely catch fire if you buy badly. Get it right and your conversion is a joy; get it wrong and you are either stranded sh
Read more →"How much does it cost?" is the first question almost everyone asks about converting a bike to electric, and the honest answer is: anywhere from a few hundred to well over a thousand, depending on choices you control. This guide breaks the spend down piece by piece, separates the budget tier from th
Read more →Fitting a hub motor conversion kit is one of the most satisfying jobs you can do on a bike: in an afternoon you can turn an ordinary machine into a capable electric one, using little more than the spanners already in your toolbox. Hub kits are popular precisely because they are forgiving. The motor
Read more →Few things in cycling cause as much head-scratching as tyre sizing. Pick up three tyres from three different decades and you might find one labelled 700x28c, another 27 x 1 1/4, and a third simply 28-622 — and depending on which numbers you trust, you could end up with a tyre that physically will no
Read more →If you have ever tried to compare two bikes, or work out whether a new cassette will give you an easier climbing gear, you will quickly bump into three overlapping ideas: gear ratio, gear inches, and development (sometimes called metres of development or roll-out). They all describe the same underly
