How Quiet Is the Birch Grolar Hunting eBike?

When it comes to hunting, stealth is everything. Movement, scent, and sound can all betray your position and ruin hours of careful tracking. That’s why serious hunters are buying into the eBike advantage—not just for speed and range, but for silent mobility. But just how quiet is the Birch Grolar, really? We put it to the test in a controlled environment, and the results speak volumes—literally.

The Sound Test: Grolar vs. Competitor

To quantify just how silent the Grolar is, we set up a controlled sound level test. The test was conducted in a sound-treated room with minimal ambient noise—an environment designed to ensure the readings came from the bikes and not external factors.

We compared the Birch Grolar to another well-known hunting eBike with similar motor power, dual-drive setup, and fat tire configuration. Both bikes were tested under identical conditions using their throttle control only (no pedaling) at a stationary position, where motor noise is most audible.

Each bike was tested five times, and the decibel readings were measured using a calibrated digital sound meter placed one meter from the motor hub. Here’s what we found:

• Birch Grolar average sound output: 25.0 dB
• Competitor’s average sound output: 29.8 dB

That 4.8-decibel difference might sound small on paper, but in the world of stealth and hunting, it’s massive. Decibels don’t scale linearly; a 4-5 dB drop represents a significant reduction in audible sound, making the Grolar noticeably quieter.

What Does 25 dB Sound Like?

To put it in perspective, 25 decibels is roughly the sound of a soft whisper or rustling leaves. In contrast, the competitor’s 29.8 dB sits closer to the sound of a quiet conversation at home. In the wild, where silence is sacred, that difference can be the reason you get within range—or scare off your game before you even see it.

Why Quiet Matters in Hunting

When you're chasing whitetail or stalking elk, you know how quickly animals react to unnatural sounds. One loud whirr from a poorly tuned motor can send your target sprinting. That’s why noise suppression is just as important as camouflage.

Here’s how a low-noise eBike like the Grolar helps you in the field:

• Get closer to your prey: With near-silent operation, you can approach your hunting grounds without alerting wildlife.
• Maintain stealth over long distances: Even when covering miles of trail, a quieter bike means less chance of disturbing natural movement patterns.
• Minimize your presence for multiple days: On extended hunting trips, keeping quiet helps preserve the area and reduce pressure on animal behavior.

Traditional ATVs or gas-powered alternatives can’t compete here. Even other eBikes often fall short if they don’t prioritize motor acoustics or frame dampening. The Birch Grolar is engineered for silence, without compromising on power or terrain-handling.

What Makes the Grolar So Quiet?

The Grolar’s precision dual 750W motor system utilizes a torque sensor for even and silent power shifting, keeping noise to a minimum even at peak torque. The 26" × 4" fat tires also help dampen vibration and noise when moving across frozen leaves, mud, or gravel. Combined, these features make the Grolar one of the quietest hunting eBikes on the market.

Beyond Quiet: All-Terrain, All-Season

Of course, silence isn’t everything—but with the Grolar, you don’t have to compromise. It’s built for serious off-road action with:

• 750W dual motors
• Up to 85 miles range 
• Front suspension and hydraulic disc brakes
• Rack and fender included
• Rugged aluminum alloy frame rated for a 400 lb load

Whether you're navigating snow, mud, rocky paths, or steep climbs, the Grolar gives you unmatched control and stealth—all in one.

Who Is the Grolar For?

If you’re a hunter who needs to access remote areas without scaring off the wildlife, the Birch Grolar is built for you. But even if you’re not a hunter, its silent operation makes it ideal for nature photographers, campers, and anyone who wants to experience the outdoors without disrupting it.

Quiet Power, Proven Performance

The Birch Grolar doesn’t just look the part—it proves its worth in testing. Our decibel comparison makes it clear: when it comes to stealth mobility in the wild, the Grolar leads the pack. From its quiet motor to its reliable handling, it’s a professional-grade hunting tool disguised as an electric fat bike.
