Why a saddle

A BMX rider sometimes forgets their race plate, their bottle in a bag, a glove... They never forget their saddle — it's already on the bike. By building the sensor right into it, there's nothing left to remember to bring: the saddle is the sensor.

Why an app

Data that's captured but never read is useless. The RAD 4 BMX mobile app (iPhone and Android) is there so that every corner, every sprint, can be read right after your training session or your moto — at the track, not three days later in a spreadsheet. The saddle captures, the app makes the data useful.

Why the coach is built in

Coach tracking wasn't added as an afterthought. A rider on their own wants to see their own telemetry; a coach wants the same thing, but for several athletes at once, with a training programme that follows from it. Both uses have existed since day one of the design, not as a paid option bolted on later.

What won't change

No data sold

Your race data belongs to you. It's there to help you train, not to be resold.

One sensor, one job

RAD 4 BMX does race telemetry. No gimmicky features that dilute the product.

Built for BMX

Designed for this specific sport — not a generic "cycling" app hastily adapted.
