There have been plenty of flawed amphibious follies over the years but through it all, Gibbs has been a rare and outstanding beacon of hope, technical excellence and real-world relevance.

It gave us the original Lotus-style Aquada (number 8 on our list of 10 coolest looking boats); it showed us the remarkably potent Amphitruck; it succeeded superbly in the creation of the one and two-man Quadskis; and now, it seems to have repeated the trick in the form of a motorbike crossed with a personal watercraft (PW).

Gibbs Biski – amphibious motorbike

The Gibbs Biski is an amphibious motorbike that can do 37mph on the water.


Given the natural overlap in riding style and operating interface between a bike and a PW, the concept makes good sense - and happily, the execution also appears to be spot on. The Biski uses a two-cylinder 55hp petrol engine that operates through the rear wheel for a top land speed of 80mph and through the Gibbs dual jet system for a top water speed of 37mph (about 32 knots). If you think that sounds a bit tame, you could always take a look at the same company’s Triski – which uses two wheels at the front alongside a 135hp engine for 45mph as a PW and 85mph as a trike.

Gibbs Biski – five-second transition from land to water

The transition from land to water takes just five seconds.


But either way, the technologies are impressively useable, enabling the Biski to make the transition from road to water in under five seconds and leap onto the plane in under three. Of course, that’s nowhere near the stinging performance of a modern high-performance ski and we don’t yet know the price - but if precedent is anything to go by, this specialist amphibian from Gibbs is likely to be much more affordable than you think.

Gibbs Biski – on-water performance

Despite moderate power and heavy weight, the on-water performance looks perfectly serviceable.
