Graham Sykes' 'Force of Nature' Roars Past 200 MPH
21 Jun
Summary
- Steam-powered bike reaches over 200 mph using a 120-liter boiler.
- Mechanical engineer Graham Sykes built almost every part himself.
- The bike aims to achieve a 4-second quarter-mile run in the future.

At the Santa Pod raceway in Bedfordshire, England, Graham Sykes prepared his steam-powered motorcycle, dubbed 'Force of Nature,' for a record-breaking speed attempt. Sykes, a mechanical engineer, handcrafted nearly every component of the bike in his backyard workshop, resulting in a machine that rivals NASA-level engineering.
The heart of 'Force of Nature' is a 120-liter boiler, heated to approximately 260 degrees Celsius, which builds immense pressure. This power is released upon starting, propelling the bike to over 200 miles per hour in roughly three seconds. The boiler, sourced from industries requiring pressurized vessels, is the only component not built by Sykes, prioritizing safety due to the catastrophic potential of a failure.
Sykes was inspired by Evel Knievel's 1970s attempt to jump Snake River Canyon with a rocket, motivating him to build his own steam-powered rocket bike. Despite the inherent risks, Sykes remains calm and focused during runs, acknowledging the trepidation that accompanies each activation.
The bike's performance, reaching 0 to 60 mph in under half a second, far surpasses conventional acceleration experienced by many. While it did not break its own records on this particular day, the runs were safe, with Sykes' wife Diane confirming all is well when the parachute deploys.
Sykes and his team have already achieved their initial goals of a 5-second quarter-mile with a 200 mph pass, proving steam's potent capabilities. They now aim to achieve a 4-second quarter-mile run, a testament to their precision, dedication, and passion for pushing the boundaries of steam technology.
