Tim Cotterill’s Rocket II Trike: 1,000bhp, V8 and Built for Speed
British artist Tim Cotterill’s Rocket II trike combines a supercharged Hemi V8 with radical design, delivering over 1,000bhp and a claimed 200mph top speed.
Tim Cotterill, better known as “The Frogman” for his whimsical bronze frog sculptures, is a figure more often associated with art galleries than with the roar of a high-powered engine. Yet, in the late 2000s, Cotterill made a dramatic entrance into the world of custom vehicles with the creation of the Frogman Rocket II trike. This one-off machine is a striking fusion of artistic vision and extreme engineering, representing Cotterill’s ambition to blur the lines between art and high-performance motoring.
The Rocket II trike is not simply another custom motorcycle conversion. Instead, it is a ground-up build that showcases Cotterill’s sculptural flair and his fascination with mechanical spectacle. With a supercharged Hemi V8 engine at its heart and a design that is as visually dramatic as it is technically ambitious, the Rocket II stands as a testament to what can be achieved when creativity is given free rein.

Design and Construction: Art Meets Engineering
Unlike most trikes, which often start life as modified motorcycles, the Rocket II was designed and built from scratch. Its chassis and bodywork were created specifically for this project, with an emphasis on both high-speed stability and visual impact. The layout features two wide-set front wheels and a single rear wheel, giving the trike a broad stance and distinctive proportions. The engine is mounted longitudinally behind the rider, contributing to its dramatic, exposed mechanical appearance.
Cotterill’s background in sculpture is evident in the Rocket II’s details. The trike boasts vivid paintwork and polished metal components, reflecting his commitment to making the vehicle as much a kinetic artwork as a machine. The result is a vehicle that commands attention, not just for its power but for its artistic presence.
- Custom steel chassis designed for high-speed stability
- Single rear wheel and two wide-set front wheels
- Longitudinally mounted V8 engine behind the rider
- Distinctive paint and chrome detailing
Supercharged Hemi V8: The Heart of the Rocket II
At the centre of the Rocket II is a supercharged Hemi V8 engine. While specific details such as displacement have not been widely published, what is clear is the engine’s formidable output: over 1,000bhp. Combined with the trike’s relatively lightweight construction, this power enables the Rocket II to achieve a claimed top speed of 200mph in a matter of seconds. Such performance is rarely seen outside the world of drag racing, and it sets the Rocket II apart from almost any other custom trike.
Cotterill’s decision to use such an engine reflects his desire to create not just a visually arresting machine, but one that delivers an extraordinary mechanical experience. The supercharged Hemi V8 is more than just an engine choice; it is a statement of intent, underscoring the Rocket II’s place at the intersection of art and engineering.
| Engine | Supercharged Hemi V8 |
|---|---|
| Power Output | Over 1,000bhp |
| Top Speed (claimed) | 200mph |
| Layout | Single rear wheel, two front wheels |
| Chassis | Custom-fabricated steel |
Performance and Impact
The Rocket II trike is not intended for mass production or daily road use. Its extreme power, combined with its unique engineering, places it firmly in the realm of show vehicles and one-off engineering statements. The trike has attracted considerable attention at custom shows and among automotive enthusiasts, who are drawn to its uncompromising specification and the way it challenges traditional ideas about trike design.
For Cotterill, the Rocket II represents a deeply personal project, an opportunity to channel his technical curiosity and creative flair into something entirely new. Its blend of mechanical artistry and high performance has made it a talking point within the custom vehicle community, where it is often cited as an example of what can be achieved when the boundaries between art and engineering are pushed.
Legacy and Reception
Since its completion, the Rocket II has sparked conversation not only about its performance but also about the possibilities that arise when artistic ambition meets technical expertise. Cotterill’s reputation as a sculptor has brought a fresh perspective to the world of custom vehicles, inspiring others to consider how art and engineering can be combined in new and unexpected ways.
Although the Rocket II remains a unique, one-off creation, its influence can be seen in the growing interest in vehicles that prioritise both design and performance. The project demonstrates that a background in art is not a barrier to technical achievement, and that the creative process can lead to extraordinary outcomes in the world of engineering.
Conclusion
The Frogman Rocket II trike by Tim Cotterill is a remarkable example of what can happen when creativity and engineering expertise are brought together. With its supercharged Hemi V8 engine, striking three-wheeled layout, and unmistakable visual presence, the Rocket II stands as a lasting testament to the power of imagination in the world of custom vehicles. While it is not destined for mass production or everyday roads, its legacy as an audacious and inspiring work of automotive art is secure.
