Why Neodymics Exists

Neodymics is a small independent publication about turning ordinary bicycles into electric ones and about the parts that make them move. It is written for commuters, tinkerers and people who would rather keep a bike they already love than buy a new one.

The three subjects we return to

Articles fall into three areas that feed into each other. A conversion kit is only as good as the motor, the motor only as good as the drivetrain it pushes against, and the whole project only matters if it replaces car trips that used to happen.

• E-Bike Conversion Kits looks at front-hub, rear-hub and mid-drive kits, battery placement, wiring, controllers and what a frame needs before anything is bolted on.
• Bike Motors & Drivetrains explains torque and power ratings, gearing, chain and belt wear, brakes that cope with extra speed and the maintenance an assisted bike demands.
• Green Transport considers cycling as everyday travel: cargo and commuter use, charging habits, battery lifespan and recycling, and how local rules treat electric bikes.

Our approach

The goal is advice a reader can act on, from choosing a kit to knowing when a chain is worn out. Claims are checked against manufacturer manuals and specification sheets, published safety standards, and local transport regulations. When a result depends on rider weight, terrain or the age of a frame, the article says so instead of promising one outcome.

Electric bike parts change quickly and rules differ between regions, so pages are revisited and revised when details go out of date.

Who reads Neodymics

Some readers are planning a first conversion and have never touched a crank puller. Others have built several bikes and want a second opinion on one stubborn problem. Nothing here assumes a workshop, a large budget or a flat commute.
