# Product Overview: Gearious

A working example of a product-overview steering file. Abridged for sharing.

## Purpose

Gearious is a web application that helps adventure motorcycle riders plan what to bring on a trip, how much it weighs, and how that weight is distributed across their bags.

The defining feature is a **real-time left/right weight balance indicator**. As a rider drags gear into their bags, a visual balance bar updates instantly, showing whether the load is weighted evenly between the left and right sides. An unbalanced vehicle handles poorly and fatigues the rider; Gearious makes the problem visible and fixable before leaving the driveway.

Gearious exists because getting a heavy, multi-bag load right has always been a mix of art, experience, and guesswork. The product gives riders the visibility that was previously only earned through experience.

## The Problem

Riders pack complex loads across multiple bags and most cannot see:

- How much their total load weighs versus the vehicle's rated payload.
- Whether the left and right sides are balanced — a handling factor that packing lists ignore.
- What is packed where without checking each bag.
- How worn riding gear factors into the overall load.

## Target Users

Optimize for the adventure motorcycle rider first. Adjacent audiences (touring, off-road, overlanding, backpacking) may show up later; don't design for them first.

| User | Priority |
| --- | --- |
| Adventure (ADV) motorcycle rider | **Primary** |
| Street / touring rider | Secondary |
| Off-road / enduro rider | Secondary |
| Long-distance & expedition riders | Secondary |
| Overlanders, 4x4 travelers, backpackers | Secondary |

## Key Features

Keep this list at the altitude of *what the product is*, not a backlog:

- **Balance engine** — Real-time left/right balance plus payload awareness. The technical heart of the product; correctness comes before everything else.
- **Kit setup** — Reusable bike, bag, and gear libraries the rider builds once and carries into every trip.
- **Drag-and-drop trip planner** — Assign gear into bags and watch balance and weight update live.
- **Reuse** — Saved setups so a rider isn't starting from zero on the next trip.

## Build Scope

This file describes the **Gearious web application**. Build for web only. A native companion is out of scope for this build — don't introduce mobile-specific coupling or assume a mobile dependency.

## Product Principles

- **Balance accuracy is safety-adjacent.** An incorrect weight or balance figure is the worst possible outcome. Correctness of the engine comes before everything else.
- **Privacy by default.** Trips, gear, and bike profiles are private unless the rider explicitly shares them. Body weight is used only for the rider's own payload math and is never shown publicly.
- **Ship the core loop first.** Validate that real riders find the live balance visualization useful before expanding scope. Each phase should be stable before the next begins.
- **Favor reliability and low operational cost over complexity.** This is a solo build.
