TwoWheelGuide

Independent cycling guides

Everything you need to know about bikes.

Clear, practical advice on choosing a bike, keeping it running, and riding safely — written in plain English, with no brand deals and nothing to sell you.

Where to begin

Three guides, one bike

Whether you’re buying your first bike or rebuilding your tenth, the answer you need is in one of these.

Choosing a bike

The five main types of bike explained, how to get the frame size right, and exactly what to inspect before you commit to a second-hand one.

Fixing & maintenance

Step-by-step punctures, brake and gear adjustment, the M-check, and a maintenance schedule that keeps small problems from becoming expensive ones.

Skills & safety

Road positioning, junctions, riding in traffic, and how to stay visible after dark — the things that actually keep you safe on a bike.

New to all this?

Nobody is born knowing how a derailleur works

Cycling has an unusually steep vocabulary problem. Walk into a bike shop and you’ll hear about groupsets, bottom brackets, tyre casings and gear ratios inside the first minute — and it’s easy to leave feeling like the answer was deliberately kept from you.

It wasn’t. All of it is learnable, and most of it matters far less than the industry implies. What actually matters is that the bike fits you, that the brakes work, and that you enjoy riding it enough to keep going.

Winter care for your bike

Salt, grit and rain will quietly destroy a drivetrain. A ten-minute weekly routine that prevents most of it.

Our approach

Why you can trust these guides

We’re readers first. Everything here is what we wished someone had told us when we started.

Genuinely independent

No manufacturer pays us to recommend anything, because we don't recommend specific products. We explain how to judge them yourself.

Tested, not theorised

Every repair procedure here has been carried out on a real bike before it was written up. If a step is fiddly, we say so.

Kept up to date

Guides are reviewed at least once a year. Each one carries the date it was last checked, so you know how current it is.

What people tell us

Rated 5 out of 5
I'd put off fixing my own punctures for about four years. Read the guide, did it in twenty minutes on the kitchen floor, and felt slightly silly for waiting so long.

The second-hand checklist saved me from buying a frame with a cracked chainstay. I'd looked right at it and not known what I was looking at.

Finally an explanation of gear ratios that didn't assume I already understood gear ratios. The traffic positioning guide changed how I commute.

Common questions

Before you dive in

Yes. Every guide is free, with no paywall, no registration, and no email required. The site is supported by advertising, which is why you’ll see ad units on some pages.

No. TwoWheelGuide is purely an information site. We don’t sell anything, we don’t run a workshop, and we don’t take commission on products.

Most of them, yes — they’re written for people working at home with basic tools. But bicycles are vehicles, and a badly assembled brake or a cracked frame can cause serious injury. If you’re not confident, have a qualified mechanic check your work.

The mechanical advice applies anywhere. Road-law specifics vary by country and even by city, so always check your own local regulations.

Each guide is reviewed at least annually, and sooner if standards change or a reader points out something that’s gone out of date.

Stuck on something?

If a guide didn’t cover your problem, tell us. Reader questions are where most of our new guides come from.
