For nerds and bikers both

Your bike is a system.
Learn it. Maintain it yourself.

Wrench is a motorcycle maintenance companion built for owners, not mechanics.

Open Wrench, pick a job See how it thinks

When we show a bike-specific number, we name its source and where it applies. If your exact bike isn't covered, we say so. Every guide starts with the why. And when a job crosses a safety line, we say so, and point you to a professional.

Trust

Named sources, honest gaps

A bike-specific number comes with its source and where it applies. If your exact bike isn't covered, we say so. Never a borrowed number.

Understanding

Why-first guides

Understand the system before you touch a bolt. The how makes sense once the why does.

Honesty

Real safety boundaries

Some jobs belong with a professional. We say which ones, and why, every time.

Inspect the logic

How Wrench thinks

No black box. The same four steps, every job, and you can check each one.

The system

Your bike is one connected machine. Every guide starts from how the parts work together, so a symptom makes sense before a fix does.

The observation

Wrench works from what you can see, hear and measure on your own bike, not from generic assumptions about a model average.

The source boundary

When we show a bike-specific number, we name its source and where it applies. What we don't know, we say we don't know.

The log

Your maintenance entries stay on your device. Each finished job makes the next one smarter.

Provenance, honestly

When a guide quotes your bike, it names the document it came from. When your exact model or edition isn't covered yet, Wrench says exactly that. No borrowed numbers, no silent gaps.

Rider soul

A bike you know feels different

Quieter. Tighter. Yours. The road reads better when the machine under you is one you understand. Wrench exists so more riders know that feeling.

Nerd brain

Every claim traces to a source

Systems over slogans, measurements over vibes. Your bike's own documentation first, and everything labelled. We would rather say "we don't know yet" than sound confident and be wrong.

The chain, two ways

A sound chain on a schedule and a chain making a new noise are different problems. Wrench treats them differently.

Routine

Chain care, on schedule

A why-first guide to cleaning and lubing a healthy chain, and to knowing when lube is not the answer. Reading it is not a ride-clearance check, and Wrench never treats it as one.
