Nonlinear — An Engineer's Ride to the World's Deadliest Race, by Lennon Rodgers

Nonlinear

An Engineer's Ride to the World's Deadliest Race

An electric superbike built by MIT students. One lap of the deadliest race on earth.

In 2011, Lennon Rodgers led a team of MIT students to design, build, and race an electric motorcycle at the Isle of Man TT — 37.73 miles of public road, stone walls, and blind crests. He did it as part of his PhD research. Nonlinear is the story of the machine, the people who built it, and the engineer who had to learn to let go.

The story

Lennon Rodgers' PhD project at MIT was not just a simulation. It was an electric superbike, designed and built by a team of students he recruited, and entered in the TT Zero — the electric class of the oldest and most dangerous motorcycle race in the world. The idea had roots in his time at NASA's Jet Propulsion Laboratory, where air quality had turned him toward electric transportation.

The build is real engineering, told as it happened: battery chemistry and the trade-offs it forces, a motor and drivetrain that had to survive a mountain, a machine reassembled on an island with the clock running. Every decision gave something up. That rule — learned early, on a lathe — runs through the whole book.

But Nonlinear is not only about the bike. It is about a lone-wolf engineer learning to lead, about the difference between control and trust, and about handing the throttle to a rider who has agreed to trust your work at racing speed, between stone walls. Underneath it all is a working-class father and a son trying to chart a different course.
