The age of electric fins has changed how we surf and paddle. Today’s riders can glide farther, fight wind effortlessly, and catch more waves — thanks to compact motors that blend technology with pure freedom.
Among the leaders, two names keep surfacing: Boost Fin and Bixpy Jet.
Both deliver real propulsion on the water, but in very different ways. One focuses on simplicity and agility, the other on range and raw power.
So which one actually wins in real-world use? Let’s dive in.

Design Philosophy
At first glance, both products promise the same thing — motorized assistance for surfboards, SUPs, or kayaks.
But under the surface, their design philosophies couldn’t be more different.
- Boost Fin follows a minimalist, plug-and-play approach. It’s a self-contained unit: battery, motor, and control all inside one fin. No cables, no deck clutter, no drilling.
- Bixpy Jet, by contrast, uses a modular system. It connects to the board via external brackets and cables, with a separate battery pack mounted on deck or in a backpack.
Both designs have merit: Bixpy offers more customization and capacity, while Boost Fin focuses on portability and ease of use.
But for everyday paddlers and surfers, less setup often means more time riding.
Power and Performance
Power output is where both fins shine — but for different reasons.
- Boost Fin Plus delivers up to 20 lbs of thrust, reaching speeds around 10 mph, which is plenty for surfing and SUP acceleration. Its smooth torque curve gives immediate response — you feel the push right when you need it.
- Bixpy Jet V4 goes further, producing 25 lbs of thrust with a higher sustained output — ideal for kayaks and long coastal trips.
That extra power comes at a cost: bulk and drag. Bixpy’s external mount and cable routing slightly affect maneuverability, especially in surf conditions. Boost Fin keeps the board’s natural feel intact — no change in balance, no added resistance.
💡 If you ride waves or short SUP sessions, responsive power beats prolonged thrust.

Battery Life and Runtime
Battery life is one of Bixpy’s biggest strengths — and Boost Fin’s smartest optimization.

Bixpy lasts longer at top output, making it great for all-day expeditions.
But Boost Fin isn’t trying to compete on sheer hours — it’s calibrated for reality.
Most surf or SUP sessions last between 60 and 90 minutes, and the Boost Fin covers that perfectly without excess weight or wiring.
It’s an efficiency-first design: you charge less, ride naturally, and skip the setup fuss.
Weight and Portability
Here the difference is clear: Boost Fin ≈ 4.9 lbs, Bixpy Jet ≈ 9 lbs (including external battery).
That’s nearly double the load — and it matters when traveling, flying, or switching between boards.
Boost Fin fits in a backpack; Bixpy requires extra mounts, battery housing, and cables.
For surfers, SUP yogis, or families who share boards, that portability makes all the difference.
Verdict: Boost Fin = grab-and-go; Bixpy = plan-and-prepare.

Noise and Experience
Both fins are far quieter than any fuel-powered system, but Boost Fin’s integrated motor gives it a clear edge in sound control.
At under 55 dB, it’s practically silent — you’ll hear the waves, not the prop.
That matters not just for peace but for safety and wildlife; many marine areas now favor low-noise electric propulsion.
Compatibility and Use Cases
|
Use Case |
Boost Fin Plus |
Bixpy Jet V4 |
|
Surfing / Short SUP |
✅ Perfect fit — light, agile, instant power |
⚠️ Usable but heavy setup |
|
Touring SUP |
✅ Long Range version extends runtime to 3 hrs |
✅ Excellent for flat water cruise |
|
Travel & Portability |
✅ Fits in backpack, no external battery |
⚠️ Requires mount kit and battery box |
Boost Fin is the more universal solution — one fin, multiple boards, minimal setup.
Bixpy Jet remains best for kayakers or long-range paddlers who want maximum thrust over convenience.

Bixpy commands a premium — and earns it for power and runtime — but at twice the cost of Boost Fin.
For most riders, that trade-off doesn’t make sense. Boost Fin brings you 90 % of the performance for 50 % of the price.
Real-World Takeaway
In controlled tests, Bixpy wins the “spec sheet” race: longer runtime, higher thrust.
But in everyday use — short SUP sessions, wave days, relaxed lake rides — Boost Fin wins where it counts:
- Faster to install
- Easier to travel with
- Feels natural underfoot
- Quiet, clean, and ready in minutes
If your goal is freedom and fun, Boost Fin delivers compact power without compromise.
If you’re chasing endurance and expedition-grade performance, Bixpy is still an excellent choice — just be ready for more weight, setup, and cost.

Final Verdict
Boost Fin = Compact Power.
Bixpy Jet = Endurance Power.
In 2026, both are leaders in their space — but for most surfers and paddleboarders, Boost Fin’s simplicity and universal fit make it the smarter everyday companion.
It’s the electric fin built for real riders, not just test benches.
