Happyrun G300 Pro – An Affordable Sur-Ron Alternative With Pedals

If you’ve ever wanted a Sur-Ron or Talaria, but couldn’t justify spending thousands of dollars, the Happyrun G300 Pro might be the next best thing. This e-moto blends the aggressive look of a dirt bike with the legal advantages of having pedals. After spending over 20 miles riding this bike on roads, bike paths, and rugged off-road trails, I can confidently say that this is one of the most fun rides I’ve tested — even with a few quirks.

First Impressions

The first thing you notice about the G300 Pro is its sheer size and weight. At over 130 pounds fully assembled, it feels more like a small motorcycle than a typical e-bike. This heft gives it a planted, stable ride, but it also means you need to be ready to handle it — much like balancing a heavy cruiser at a stoplight.

From the moment I unboxed it, the bike gave off serious Sur-Ron vibes. The 72V battery, 6500W hub motor, and inverted front forks scream power and durability. Happyrun ships the battery separately to save on freight costs, so expect to assemble the bike and wait a couple of days for your battery to arrive. Setup was straightforward but more involved than your average e-bike, taking me about an hour.

The styling is what really draws people in. During my rides, I got tons of thumbs-ups and curious stares. With its dirt bike frame, knobby tires, and bold color options like blue, orange, camo, and black, it truly looks like a legit off-road motorcycle.

Riding Experience

Once you hit the trails, this bike’s suspension setup really shines. The inverted front forks and rear air shock soak up bumps like a sponge, making rough terrain feel smooth and controlled. It feels purpose-built for off-road fun, unlike many e-bikes that simply can handle dirt trails but don’t feel at home there.

The hub motor delivers steady, predictable acceleration. While it doesn’t have the instant torque of a mid-drive motor, it’s still capable of reaching 45–47 mph on flat ground, with the potential for 50 mph under ideal conditions. The power builds smoothly rather than hitting you all at once. This makes it beginner-friendly, since you won’t accidentally wheelie or lose control with a twitchy throttle.

On the street, the G300 Pro keeps up with traffic far better than a typical e-bike. However, the stock brakes leave a lot to be desired. They’re functional but not confidence-inspiring, especially at higher speeds. Upgrading to higher-quality brakes is a must if you plan to ride aggressively or on busy roads.

Off-road is where this bike really shines. The knobby tires bite into dirt and gravel, and the suspension inspires confidence. It’s like taking a wild horse out on open land — it just feels natural. Even on rugged, uneven terrain that would challenge most e-bikes, the G300 Pro powered through without hesitation.

Range & Battery Life

The 72V 30Ah battery provides excellent range, especially when cruising at moderate speeds. After a 20+ mile ride, I still had three out of five battery bars remaining. If you ride mostly under 35 mph, you can expect impressive efficiency, but frequent full-throttle riding will naturally drain the battery faster.

Charging is straightforward with the included 5A charger, taking roughly six hours for a full charge. The battery itself weighs around 30 lbs, so removing it for charging is doable but not ideal for everyday lifting.

Who Is This Bike For?

The Happyrun G300 Pro is perfect for riders who want the look and feel of an E-Moto without paying Sur-Ron prices. At roughly half the cost, it offers similar styling and a comparable top speed, making it ideal for:

• Budget-minded riders
• Beginners who want smooth power delivery
• Off-road enthusiasts who need a rugged, stable ride
• Riders who want to blend in on streets without drawing too much attention

If you’re looking for a first e-moto or simply want something fun for weekend trail rides, this is a fantastic option.

Final Thoughts

The Happyrun G300 Pro exceeded my expectations. At first, I wasn’t sure how I’d feel about a hub-motor dirt bike, but after spending serious time with it, I get the appeal. It may not have the raw torque of a mid-drive like the Sur-Ron, but it delivers tons of fun, speed, and style at half the price.

If you can budget for a brake upgrade and understand that it’s a heavy machine best suited for throttle-only riding, this could easily become your new favorite e-moto. Whether you’re hitting the trails or cruising the streets, the G300 Pro is proof that you don’t need to spend $4,000+ to have a blast on two wheels.
