Where each one wins

Two different propulsion philosophies

The Mossa is a pedal kayak first. Its drive lives below the hull in the water column and combines the pedal mechanism, the electric motor and the steering. The FluxJet is pure electric: water comes in through an intake on the bottom of the hull, an impeller accelerates it, and it leaves through a steerable nozzle flush with the rear. The kayak is built around that drive.

Where the VoyaX Mossa wins

Pedal and motor in one
If you want to pedal for exercise and switch to electric when you're tired, that's exactly what the Mossa is built for.
Built-in SpotHold
GPS position holding is built into the drive, so you don't need a separate anchor system.
Capacity and size options
580 lb capacity on the 128, and a smaller 9'7" Mossa 97 if storage is tight.
Battery in the box
The 48V battery and charger come with it. With FluxJet you buy your own battery.

Where FluxJet wins

Skinny water
FluxJet runs in about 4 inches with nothing below the hull. With the Mossa, shallow sections mean pulling the drive and paddling.
Weeds
No prop and no pedal fins to wrap. The intake can still pick up weeds: slow down in thick vegetation and use reverse to help clear it.
Your battery, your range
Any standard marine battery from 12V to 60V. Go lighter for short trips or bigger for long days. See our battery guide.
Lighter to load
Rigged and ready, before the battery, a FluxJet is 122 lb. A Mossa 128 is 151 lb before its battery and 164 lb with it. That difference matters every time you lift it onto a rack or a truck bed.
No pedaling at all
A throttle dial and foot-pedal steering. Nothing to pedal, so it suits anglers who'd rather not.

The honest verdict

Pick the one that fits your water

If you want to pedal, need built-in GPS position holding, and mostly fish open water deep enough for a drive below the hull, take a serious look at the VoyaX Mossa. It's a well-designed kayak that solves real problems.

If you want pure electric simplicity, fish skinny water or weedy flats, and want to pick your own battery, the FluxJet is the better fit.

Questions

No. Position holding is not built in. Anglers use a stake-out pole or an anchor.
Can the VoyaX Mossa run in shallow water?
The Mossa's drive sits below the hull. US retailers say it can be pulled out of the drive well so you can paddle through shallow sections, then put back. The FluxJet runs in about 4 inches with nothing below the hull.
Which one costs less?
The FluxJet is $3,499 plus shipping and tax, and you add your own battery. The Mossa 128 lists at $4,499, with US retailers offering $3,999 early-bird pricing that includes the battery and charger.
Can I pedal a FluxJet?
No. The FluxJet is pure electric with no pedal drive. Paddle holders are included, and we recommend always carrying a paddle.
