red shark bikes have unveiled a series of trimarans allowing cyclists to take on aquatic surfaces like rivers, lakes and seas. CEO and industrial designer josep rubau is the person behind the invention, who has previously designed cars for volkswagen as well as the tramontana supercar.

red shark‘s three models include adventure (for the athlete looking to improve performance), fun and sport (targeting people who love expeditions or discovering new places) with the first two made of high-density polyethylene (HDPE). the adventure adds frame-mounted packs and a waterproof storage trunk as well as thicker plastic reinforcing the underside of its three hulls. the sport is constructed almost entirely of lightweight carbon fiber.

all three models boast a foldable design, retractable rudder, salt water-proof drive shaft and stainless steel nuts and bolts. the fun is at the lower end of the price range costing from €4,995 (around US$5,783) whilst the adventure is priced up to €6,995 ($8,098) and the sport comes in a little higher at €9,995 ($11,570).

  • Looks like more of a still water lake craft. Are there no gears? Thanks.

    steve hassler says:
  • Why would you need to wear a helmet when operating this? Also, does it make everything go in slo-mo?

    Otto Cosmopotron says:
  • why do you need a bike helmet when riding on the water? I think a flotation device is more appropriate. Cool idea, does it reverse?

    Garry McLeod says:
  • Imagine doing this mid day, in the blistering sun, doing like 5 mph, so no wind cooling you, looking at the cyclists on land, flying past at 20 mph.
    Or even worse, on a sudden change in wind and current, which combined can outrun your maximum speed of let’s say 10 mph… Then what?

    Fanel Treimii says:
  • What’s the efficiency of this thing, doesn’t seem like any of the “bikers” are getting anywhere. They all look lethargically peddling in place

    rjayn says:
  • should be recumbent. High center of gravity is no good in big water.

    elwood says:
  • As stated by others, a helmet is not necessary, but a PFD is when using this ‘bike’. Also it could certainly benefit from a recumbent positions for the cyclist and some sort of flywheel to keep the momentum going.

    Batavier says:
  • In this day and age, its boring. The thing needs to be on a hydrofoil and actually get some speed up. If it does it could become an olympic sport. A leg powered hyrdofoil that goes FAST.

    Kelly Hunt says:
  • She needs the helmet because the boat is so short, it’s likely to nose dive and dump the rider on rocks or an oyster bed. Expandacraft has a 16 foot modular pedal drive catamaran for less that 2K.

    James Wesley Stevenson says:
  • I say put a tow ring in front, and learn to do wave running and eventually some tricks behind my Mastercraft:)
