Speed with Guy Martin

In his second high‑octane challenge, the rider attempts to break the world record for riding a motorcycle across water. He is assisted by a Cambridge professor and a team of marine engineers who provide the necessary expertise and equipment. The endeavour aims to push the limits of hydro‑motorcycling.

Hydroplaning Bike is an episodic programme that follows a thrill‑seeker through a succession of high‑energy stunts. In this installment the focus shifts to his second adrenaline‑charged challenge, positioning the rider at the centre of a daring venture that pushes the limits of conventional motor sport. Each episode builds on the previous feats, highlighting the rider's relentless drive for new extremes. The core of the episode sees the rider attempting to claim the world record for riding a motorcycle on water. To achieve this, he enlists the support of a Cambridge professor and a team of marine engineers, whose combined knowledge is intended to keep the bike stable while it skims across the surface. The Cambridge academic contributes scientific insight into the physics of hydro‑planing, advising on the forces at play when a motorbike meets water. Meanwhile, the marine engineers focus on the practical aspects, designing modifications that allow the vehicle to remain buoyant and controllable during the high‑speed run. The stunt is framed as a high‑risk, adrenaline‑filled pursuit that aims not only to set a new record but also to demonstrate how academic and engineering expertise can be merged with extreme sport. Success would hinge on the seamless cooperation between the rider, the professor and the engineers as they tackle the water‑borne challenge.
