Product Awards

A genuine cycling experience on water

Manta5’s sole objective has been to recreate the feeling of cycling on water with a design that prioritises speed, agility, and precision handling. The new SL3 Hydrofoil Bike breaks away from conventional water bikes that utilise pontoons or hulls, offering a revolutionary new ride experience.

Experience the thrill of a completely unique mode of water mobility elevated above the chop and swell. Features include patented deep water hydrofoil launching technology, 10 levels of electric assist coupled with throttle override and quick connection parts for super easy transport and storage. In less than an hour of practise majority of people become a confident water rider.

Are you ready for a new adventure?

Get ready to explore over 70% of the world’s surface. 


Designed for the toughest conditions

The SL3 doesn’t just handle the chop and swell, it turns those conditions into a playground for thrill seekers. Hydrofoils lift you above the short wind chop and the reduced drag allows you to pierce over and down swell. 

Adding to the throttle and additional motor power all SL3s come standard with free spinning propellers.


A guaranteed thrill for experienced riders.
