At first sight, Manta5 looks like a stationary bike and water jet ski lovechild. The whole gadget has an aluminium frame and weighs around 20 kg (44 lbs), and can be partially disassembled for transport in the back of a car. It’s designed for riders weighing between 70 and 100 kg (154 and 220 lbs), and can be used in both fresh and salt bodies of water. Although Howard-Willis admits that Manta5 has some learning curve, mastering it is like, well, riding a bike for the first time. You don’t have to worry about tipping over, the bike has buoyancy modules that allow it to stay upright, even if you decide to dismount and get back up while in the middle of a lake.
Manta5 also features two carbon fibre hydrofoils that provide lift, and a 400-watt motor that boosts the rider’s pedalling power to turn the propeller. The same with electric bicycles, you can adjust the amount of assistance you need while you ride (sail?) depending on how hard you want to exercise. The existing prototype can reach a top speed of 15 to 20 km/h (9 to 12 mph) and one removable battery charge will get you about one hour of aquatic cavorting. But the first limited-edition model, the Hydrofoiler XE-1, which should debut mid-November, makes promises to have more battery stamina and be even faster.
“I want these bikes to go well beyond just being a leisure product – I want it to be a sports product so it’s competitive,” says Howard-Willis. “If it’s competitive it’s a whole different market it fits into, and who knows, one day it might be in the Olympic games. I can see that, it may take a while to get there, maybe I’m too ambitious, but like I say, I’ve always been a dreamer.”
The price is yet to be disclosed but, according to the inventor, it should be “similar to that of other quality water sports products.” Although the pre-sale should start late 2017/early 2018, the delivery is estimated for late 2018, so we’ll have plenty of time to see how realistic all those aspiring plans were.
