Birch Grolar Review: The All-Wheel Drive Tank Built for the Backcountry

Birch Grolar Review: The All-Wheel Drive Tank Built for the Backcountry

In the competitive world of hunting e-bikes, many brands simply slap a camouflage wrap on a standard mountain bike and call it “off-road ready.” Birch took a different route. With the Birch Grolar AWD, they have engineered a purpose-built hunting machine that prioritizes raw torque, hauling capacity, and “get-home-no-matter-what” reliability.

After putting the Grolar through its paces, here is our deep dive into why this bike is quickly becoming a favorite for hunters and backcountry explorers in 2026.

1. The Powerhouse: Dual-Motor AWD System

The standout feature of the Grolar is its dual 750W hub motors. While many bikes struggle when the trail turns vertical, the Grolar thrives.

• 160Nm of Torque: To put that in perspective, that is nearly double the torque of a high-end mid-drive mountain bike. It doesn’t just “assist” you; it claws you up 45% inclines. 
• Selective Drive Modes: The bike features a dedicated switch allowing you to toggle between Front-Wheel Drive, Rear-Wheel Drive, and Full AWD. 
  • Pro Tip: Use Rear-Wheel for flat logging roads to save battery, and engage AWD the moment you hit loose sand, deep mud, or a steep ascent. 

2. Hauling & Payload: The 400-lb Workhorse

A hunting bike is useless if it can’t bring the harvest back to the truck. The Grolar is built like a tank to handle extreme loads.

• 400-lb Payload Capacity: The reinforced 6061 aluminum frame is rated to carry a rider plus over 100 lbs of gear on the rear rack alone. 
• Integrated Racks: The heavy-duty rear rack is bolted directly to the frame, providing a stable platform for game bags or a custom DIY rack (like the ones we’ve seen hunters use for frame packs). 

3. Suspension & Ride Quality

Fat tire bikes can often feel “bouncy” or disconnected from the trail. Birch addressed this with a sophisticated suspension suite:

• 180mm Inverted Air Fork: This is a massive amount of travel. The inverted design reduces “stiction” and provides a much plusher feel over rocks and roots than standard forks. 
• Suspension Seatpost: Paired with a wide, cushioned saddle, the seatpost takes the sting out of “washboard” dirt roads, allowing you to stay in the saddle for 30+ mile scouting trips without fatigue. 

4. Range and Battery Management

The Grolar is equipped with a massive 48V 25Ah (1200Wh) battery.

• Real-World Range: In Eco mode with light pedaling, Birch claims up to 85 miles. In a real-world hunting scenario (AWD engaged, heavy gear, steep hills), you can realistically expect 35–45 miles—which is still enough for a full day in the deep woods. 
• IPX5 Water Resistance: The battery and electronics are well-sealed, meaning you can power through 18-inch puddles or heavy downpours without worrying about a short circuit. 

5. The Verdict: Pros and Cons

Pros	Cons
Unstoppable Torque: AWD mode is a game-changer for mud and steep hills.	Weight: At 109 lbs, it is heavy. You’ll need a motorcycle-grade hitch rack to transport it.
Braking Power: 180mm dual-piston hydraulic brakes are essential for heavy loads.	Menu Navigation: Switching between motor modes can be slightly cumbersome on the fly.
Rugged Build: Built-in fenders, metal racks, and puncture-resistant tires.	Size: This is a large bike; shorter riders may find the stand-over height challenging.

 

The Birch Grolar isn’t a “casual” e-bike. It is a heavy-duty utility vehicle designed for the person who needs to go 20 miles into the backcountry, stay there for three days, and come back with a 150-lb load. If you prioritize power and durability over “lightweight” aesthetics, the Grolar is one of the most capable partners you can take into the wild.
