Letting you know about the Stoke Foil Boost

Hi everyone, we’ve been working on a product for the past couple of years that might be of interest to this group called the Stoke Foil Boost.

The Stoke Foil Boost is an innovative electric propulsion system designed to get you foiling more. Its powerful motor lifts your foil with fingertip control, letting you fly on days when you previously thought you couldn’t. It puts you in charge of the conditions. My goal was simple – get more time foiling. We aim to let riders make their own conditions. To be up and riding more often, more effortlessly and more enjoyably.

I’d love for you to check out more about the Stoke Foil Boost via the link below, and I’m more than happy to chat foiling and answer any questions you may have!

Can you let us know the Wh of the battery so we can make a comparison to how long we think the battery will last compared to existing systems if using it on efoil mode to link waves, etc…? Not sure why the Wh of the battery is being kept as a secret.

I applaud you on the clean design straight out of the gates!

But have to agree with above, not seeing any listed battery capacity/run time or comparable thrust/power figures makes comparisons to the well known Foil Drive difficult.

Also for people who want to use it on low volume prone boards, remote reception when submerged is another important factor

It says “50 boosts” worth of battery, so probable a couple minutes of run time. The battery is tiny, looks less than 1/4 the size of the Foildrive battery and 1/100th the size of the standard Lift battery.

Unfortunately there are no secret miracle batteries out there, (currently) battery power is linearly related to size/weight.

Still could be cool but definitely a different category than Foildrive (mixed boost/ride) and Lift (full time riding)

I own one. (I got it used from a fellow poster here.) I’ve only used it a couple times so far. No affiliation to the company. 6’4" 100+kgs.

I bought it primarily to help ease likely frustration in learning to downwind without having to rely on a friend for pickups / dropoffs.

My last session, I spent about an hour using it in bay-type chop. The wind was a bit too light and the chop a bit too small. I used Low Power to motor upwind while seated, then Medium power when pointed downwind to help get on foil.

So I would guess the Stoke Boost was “in use” – powered – possibly 75% of the time. The Low Power mode is slow, so going upwind was a long slog. I probably spent 30+ minutes total just upwinding. Medium Power has plenty of power. So much that you are ultimately holding the foil down with your front foot. Since the wind was a bit weak and the chop was a bit small, I was using Medium power probably 1/3 of the time downwind… I would come off of foil and then get going with medium power again. It’s not a “squirt” and then you are up. You ramp up to speed holding the foil down, and then you ollie up on foil and kill the throttle. I was sort of eFoiling around a bit more than I intended on Medium looking for a trough to angle in behind to start my unpowered glide / pump.

I had over 50% battery power left after the hour… when the thing was in use possibly 75% of the hour. Is that good or bad? I don’t know. I quit because I was spent in cardio and quads from pumping the big board so much, not because of the battery.

How great is it that you can do a self-downwinder like this? No pickups and dropoffs. No hassle.

There are plenty of obvious issues that eFoils / foil assists create. Setup time on the beach is longer for sure. Batteries are heavy (this battery is not small or light by the way). There’s drag from the motor / prop. The connection will be lost if the bluetooth connection on the deck of the board is lost due to water on it. Battery life will always be a limitation (no miracles as Rad Duke says). Those are obvious.

And there are plenty of issues that – if you haven’t used one – you will be surprised by. Like your weight distribution under motor power is much different than under “natural” power, and you have to learn to make those adjustments as you kill the motor power and try to foil. That takes a bit to adjust to for sure.

I have used eFoils unpowered in the surf. I have used FoilDrive the same way. I have used the Stoke Boost. I think they all increase your waveriding time in waves at higher tides where you can’t normally catch them. They all have pluses and minuses. With Stoke, the positioning of everything right under your stance is it’s big plus. It doesn’t affect your normal foiling feel that much. Another plus is it’s all pretty self contained – setup is easy as far as these things go – bolt it onto any mast.

In my time with it, Stoke Boost seems to have plenty of power and plenty of battery life. Is it worse than FoilDrive? I don’t know… maybe? I haven’t done an A/B test. Is the benefit of it being able to bolt on any mast and it being right under your feet while foiling worth a possible decrease in battery life? I don’t know… maybe? It is nice!

I don’t know why Stoke the company chooses not to publish certain technical data. I don’t have enough sessions to say anything definitive. Other than…

Does Stoke have enough power and battery to meet my needs at 100+kg? Yes. That’s all that matters to me. Is it nice to bolt it onto any brand of mast, to have fewer parts to maintain, and to have it directly under my feet while foiling? Yes.

Would I be just as happy if I had bought a used FoilDrive instead of a used Stoke? I don’t know. Probably!

I have only used the Stoke a couple times, as prone foiling and winging have been good for a long stretch lately without any boost… and the downwind bug hasn’t gotten hold of me yet (feels like more work than fun!). But based on my experience, the amount of power or the battery life of the Stoke Boost won’t be an issue for me.


Great post XLFL much appreciated.

The two best sources of “information” I’ve got on the stoke has been via your review and a youtube review. It really is a pity the most important technical information for someone looking to purchase a device like this isn’t readily available, it’s a lot of money to take a leap of faith in.

I’m actually pretty much the target demographic I’m a big believer in “hybrid foiling” I currently own a FD but I wear the battery/box on my waist (which isn’t supported by FD so it’s a calculated risk) but to me a light nimble board that I can paddle on and use all of the deck is what’s most important to me. I’m a lightweight 70kg rider on a 29L prone board using it in all sorts of surf, pretty much using it to chip in pump up above the pod then glide and surf like a normal foil then choosing between pumping or efoiling to link the next wave.

I also have no affiliation to any company (I wish send me freebies guys!!) I just want the best tool for the job, I’d love nothing more than to do an honest back to back comparison of these two products for my use case but for $5k a pop that’s not happening any time soon.

Hi, some great questions here. When looking at usage time, there is more to consider than just the Wh of the battery, which is why we have shied away from discussing usage time simply in terms of capacity (you don’t consider how far a car can drive just by looking at the size of the fuel tank, and this is a similar scenario with the quality and efficiency of the motor, propeller, electronics and battery management system all playing a part in usage time). We’ve designed and built a very efficient system with high end componentry to maximise ride time, so we have focused our information on how many launches you can get rather than the fuel tank size. We promote that you can expect over 50 launches from the standard battery, with a launch being estimated at 15 seconds. We also promote that you can expect 12-15 minutes eFoil ride time (real world, not a 35kg theoretical rider) from the standard battery. But all that said, to answer the big question directly, the standard battery is 210Wh capacity. The astute reader might also ask why I am referring to a “standard battery” and whether there is something soon to be released of a different capacity… watch this space :slight_smile:


Thanks for the clarification on this figure.

Would still love to test this and compare to my “prone setup” foil drive as initial thrust, prop water engagement, remote reception, pod drag, and battery life can make or break a session.

But again I welcome competition in this market and applaud you on a neat looking design! Good to see the Aussies leading the way.

We recommend keeping an eye on our quickly growing list of retail partners to see if there is one in your area, as most of them will have demo units. Alternatively, drop us an email, and we can let you know when one is nearby: Stoke Foil Boost | Electric Foil Assist | Foil More

Is the current battery legal to go on an airline for trips?

That’s great to know! I wanted to know about how the battery swap procedure would work. If I were to swap the battery out while I’m in the sea, would the battery get damaged from saltwater somehow? That’s one of my biggest inconveniences with foil drive. You have to be super meticulous and careful when battery swapping. If your battery is completely waterproof and has zero chance of getting damaged then that would stand out as a benefit.

Hi @HRMcDowell, the battery capacity is too high to take on airlines as carry-on luggage and must be sent as freight. We are however shortly going to be releasing a travel capacity battery that you can take with you. I’d suggest subscribing to email updates on our website to hear when this is released. There are a few more exciting announcements coming soon too! :slight_smile:

Hi @Meow, although the battery is very quick and easy to swap with a simple locking ring, it’s not designed to be changed in the water so you’d still have to go back to the beach to do it.
