Tl;dr - What's new?

SKF Bearings (for real this time):

For almost a year, we battled with vendors providing us FAKE SKF bearings which we refused to put in out original Superflux. Now, we are finally able to provide the Best motor in the world with the best bearings in the world. Our bearings are 100% genuine and verifiable through the SKF app on your phone!

These bearings cost >$200 a set in most countries, and we will be including it on the Superflux with almost no cost increase to the overall motor.

The Thunder Tire!

Yes, the new Thunder 11.5 inch tire will be unveiled in the coming few weeks, and all motors will ship with the new thunder tire, which will be a medium-soft compound to tackle both streets and trails.

Plug-in single connector: 

We now have a single plug-in locking proprietary connector with 4mm bullet connectors and a 6 pin hall connector; the only one of its kind in existence. This connector will make the Superflux more accessible to a wider crowd, and easier to build Funwheels,  do swaps and tire changes!

Improved axle block:

We got rid of the original FM style axle block and improved the thermals and the looks of it.


We spent 1000s of $s to research making a better performance Superflux with stronger magnets, different kvs, etc., but the conclusion (data will be shared in a video soon) is that the original Superflux combination is the best combination in terms of performance, speed and torque. therefore, the motor will retain the same kv and performance characteristics as the original motor.


Pre-orders are now LIVE (limited stock available for batch 1).

Shipping will begin on 15 November. 




The original SuperFlux defied all odds and exceeded all expectations. The Superflux Mk 2 is here to, believe it or nor, be better than its predecessor.

Here's The original superflux in action: 






60-100V (12S to 20S Battery pack or more).


No-load speed ~ 1200rpm!

Top speed ~ 35+ mph or 60+ km/h! (can achieve freespin of more than 100km/h with field weakening).


> 50Nm (more than you will ever need).

The SF wheel is made to give you the greatest torque and top speed that is possible from a 6 inch wheel.

These are real world numbers and not exaggerated confusing HP numbers.


115mmx90mm stator (biggest ever).



Remie and I have designed the SuperFlux motor to be compatible with the original Funwheel Kit, the new Thunderbolt kit, and the FM XR rails and frame to convert your old XR to a SuperFluXR!

Just take your old hub out of the XR and drop the new one in.

Adapters and bolts ship with the hub.

As with another reviewer, my Superflux arrived damaged (dented as cracked) due to poor packaging in the first batch. Despite the original statements about replacing damaged hubs and several months of comms with them directly, I never received any real solution. In all my dealings with OW vendors (Craft & Ride, The Float Life, Street Shred, Z Battery Solutions, Floatwheel, Fungineers), Fungineers has had the worst after sales support of the lot.

Other than the issues specific to the early batch, the motor is powerful and smooth.

Insane performance!

I tried it and it gets you way out of your comfort zone. This is meant for racers and speed freaks like myself. Basically a compact euc motor. I was ripping at 50kmh (32mph) easy with this one. Couldn't even hit 85% duty cycle 😅🫡🔥🤙💯🙏

Very Powerful but also very heavy, no more tilt back with Vesc

I have bought this Superflux to install on my Vesc. This is really powerful compare to my previous XR Hypercore. But it is more heavy also. It could be good if Fungineer could propose a version with wires identical to FM models. My Because soldering bananas connectors 3 to 6 is not easy... I am very happy with my thunder rails and Superflux. Thanks a lot Fungineers!

Shipping was fast and packaging was good definitely cared for the product and customer satisfaction however I can't ride it yet otherwise would give 5 stars I did an inspection on the hub motor and everything was great

SuperFlux Super Motor

Fast packing and shipping proces. Similar quality than oringnal hypercor motor produktion. what I expected most from the motor? MORE torque and that's what I got, the engine is noticeably more efficient. I have no heat problems. My weight is over 110kg. power consumption naturally increased. I Have 84v 10Ah battery Normal Maximim 40-50km
