SiFly eFoil

The SiFly brand

SiFly is an eFoil manufacturer from Bulgaria: founded in 2019 and headquartered in Sofia. By eFoil standards that makes it a young brand, yet within a few years it has become one of the most talked-about European names. The recipe sounds simple, but hardly anyone has pulled it off before: an eFoil built in Europe that costs noticeably less than the premium brands.

To see why that is a big deal, look at how the market has split. For years it has run between two poles: the premium manufacturers on one side, led by Lift from the USA and Fliteboard from Australia, and the budget challengers from China on the other, headed by Waydoo. Until now, a board actually built in Europe almost always meant a premium purchase. That is the gap SiFly targets: production in the EU at prices close to entry level.

The international reception backs this position up. Tests and rider reports from 2026 keep landing on the same phrase, “the European alternative to Flite,” often adding that it is the best price-conscious pick in the EU. Those are reviewers' impressions, not objective measurements. Still, the direction is clear: SiFly now ranks among the most relevant newcomers for anyone who won't (or can't) pay a premium price but is rightly wary of cheap boards of unknown origin.

For buyers in Europe there is one more reason to give the brand a closer look: Sofia sits inside the EU. A package from there reaches you without crossing a customs border, and when it comes to shipping, spare parts and everything that follows the purchase, an EU manufacturer is simply easier to reach than a head office in California or Sydney. What that means in practice is the subject of the next section.

One point deserves a sober look: SiFly is a young company, and with a young manufacturer part of your pre-purchase homework should not be about the board at all, but about the support behind it. Before ordering, ask how warranty handling works, how quickly you can get spare parts or a second battery, and where software updates stand. Those questions are fair to ask of any brand, but with a company only a few years old the answers tell you the most: a good manufacturer responds with confident, concrete replies.

Models and prices

The SiFly lineup was rebuilt from the ground up for 2026 and now splits into three clearly separated families. The Lite line brings inflatable boards for beginners and families; the Rider family is the cheapest way in, built in EPP foam; and the trio of Stellar R / S / X forms the full-carbon premium line. The earlier ECO and E models are gone from the lineup. Price-wise, everything sits roughly between $5,990 and $9,490: even the carbon flagships stay below what the Western premium brands charge, although every board is built in the EU.

All sets share the swappable PowerCell battery (44.8 Ah / 58.8 V), up to 120 minutes of ride time and a complete kit: board, battery, hydrofoil, wing set, remote, fast charger and bags are all in the box. For a sense of how the whole market is priced, see our eFoil price guide.

A practical tip for ordering: always calculate the final price for the complete package. Battery capacity, wing size and accessories (a second battery, bag, charger) move the total considerably, and two offers that look identical on paper can put very different gear in the box. A spare battery, for example, can double your time on the water, since one charge typically covers about an hour of hard riding; it is also a hefty line item on the final bill.

When you choose between the models, the same ground rules apply at SiFly as with any brand. As a beginner you learn faster on a bigger, more stable board with a bigger wing; smaller boards and wings are quicker and more eager to turn, but they demand experience. If you weigh over 80 kg, plan on a larger wing from the start; a bigger wing also flies on less power, so the battery lasts longer. Before ordering, look past the price to each model's board and wing sizes on the manufacturer's site. All the criteria (board size, wing size, mast length, battery) are covered in depth in our eFoil buying guide.

SiFly and the competition

SiFly occupies the gap between the entry level and the premium segment: its base price sits above China's Waydoo but below the Western premium brands (Lift, Flite, Aerofoils), and in return you get EU manufacturing with real warranty support behind it. The carbon Stellar family was built explicitly to challenge the premium boards, at prices about €4,000 to €5,000 lower.

Every current model from the active brands, with prices, ride times and target riders, sits in a single table in our eFoil comparison.

Who is SiFly for?

The typical SiFly buyer is a price-conscious European who refuses to give up the safety net of a real warranty. If you have scrolled through the premium price lists and €10,000 to €15,000 felt like too much, yet you would not entrust that money to a cheap board of unknown origin either, you are exactly who SiFly is aiming at.

The most interesting comparison plays out inside the budget class. China's Waydoo is the value champion of the category and remains very strong on purchase price alone. SiFly answers with something a manufacturer in China, by simple geography, cannot offer: production, shipping and warranty handling inside the EU. If you are torn between the two, you are really deciding how much geographic proximity is worth to you. Which matters more: the lowest sticker price, or knowing that a warranty case never turns into a project spanning continents?

At the other end of the scale sit the premium brands: Flite and Lift offer a more mature ecosystem and a wider model range, at higher prices. If the question is how much to spend on your first board of your own, a rule of thumb helps: as a beginner, your experience depends far more on practice than on top-shelf gear. An affordable board with clean warranty coverage, plus a few hours with an instructor, is frequently a better investment than the most expensive model with no lessons at all.

And there is a third group for whom the pricing can get especially interesting: rental operators, surf schools and vacation-home owners. If you are buying several boards rather than one, because you rent them out or half the family rides, the per-board savings multiply. EU-based spare-parts supply then becomes a business argument too: for a rental operation, every week a board spends in the shop is lost revenue.

Who is SiFly not for? If you already have serious eFoil experience and are choosing a brand for one specific premium feature, or you simply never buy anything you have not tested, the young brand and its thin on-the-ground presence can be a drawback for now. In that case it pays to wait until you can stand on one yourself, or to look at brands that are easier to try where you live.
