The 60-Mile Moped Beast: Our Real-World Happyrun G50 Electric Bike Review

621

Imagine tearing through rugged trails or zipping across town with a surge of electric power at your command. That’s the thrill of the Happyrun G50 Electric Bike—a beastly mountain ebike packing a 1500W peak motor and fat tires built for all terrains. Launched in late 2023, this bike from Happyrun combines raw strength with practical design, featuring a removable 48V 18Ah battery, hydraulic brakes, and a full suspension system that tackles bumps like a champ.

Happyrun, a rising name in the ebike scene, is known for crafting high-performance electric bikes that don’t skimp on durability or style. The G50, their flagship mountain model, arrived with a bang—offering a top speed of 31 mph and a range up to 68 miles with pedal assist. Since its debut, it’s remained largely unchanged, a testament to its solid initial engineering, though minor firmware tweaks have improved battery efficiency based on user feedback.

Having ridden the G50 for weeks, I’ve pushed it through muddy paths, steep climbs, and urban streets. It’s a machine that feels alive—responsive, tough, and ready for anything. From its aggressive stance to its smooth ride, this ebike promises adventure without compromise. Let’s explore what it brings to the table.

Is Happyrun G50 Electric Bike for You?

The Happyrun G50 addresses a key need: delivering power and versatility for riders who want to explore beyond paved roads. It’s perfect for adrenaline junkies hitting trails, commuters dodging traffic with speed, or outdoor lovers needing a bike that handles sand, snow, or gravel. With five pedal-assist levels, throttle mode, and a 7-speed Shimano drivetrain, it adapts to your pace and terrain effortlessly.

It’s not for everyone, though. If you’re a road cyclist prioritizing lightweight frames or a casual rider who rarely ventures off asphalt, the G50’s 77-pound bulk might feel excessive. Budget-wise, it’s a mid-to-high-tier option—not the cheapest ebike, but far from the luxury stratosphere. Beginners will find it approachable; the controls are straightforward, and assembly is manageable with the included tools and a bit of patience.

What We Like About Happyrun G50 Electric Bike

The G50’s 1500W peak motor (750W nominal) is a force of nature. On my rides, it conquered 20-degree hills with ease, hitting 31 mph on flats—plenty of grunt for thrills or towing light loads. The 48V 18Ah battery delivers as promised; I clocked 60 miles with moderate pedal assist on mixed terrain, and even throttle-only got me 30 miles. Charging in 4-6 hours is reasonable, and the removable design makes it simple to juice up indoors.

Ride quality shines too. The full suspension—adjustable front fork and rear shock—smooths out rough trails, while the 26×4-inch fat tires grip everything from mud to pavement. Hydraulic disc brakes stop hard and fast, even in rain, giving me confidence on steep descents. The Shimano 7-speed gears shift crisply, and the LCD display tracks speed, distance, and battery life clearly. At 77 pounds, it’s hefty, but the aluminum frame feels rock-solid, supporting up to 400 pounds of rider and cargo.

What We Don’t Like About Happyrun G50 Electric Bike

Perfection eludes even the G50. Its 77-pound weight is a workout to lift—hauling it onto a car rack or up stairs left me winded, even with the battery out. Throttle-only range tops out at 30-35 miles, fine for short trips but less impressive for pure electric use; pedal assist is essential for longer hauls. The rear suspension, while effective, creaks under my 200-pound frame on bumpy descents, a minor but persistent annoyance.

The headlight is decent but not dazzling—night rides on unlit trails demanded extra caution, and there’s no taillight for rear visibility. Assembly took longer than expected (about 90 minutes), as the instructions skipped some torque details, leaving me to double-check online. Finally, the fat tires, while unbeatable off-road, add drag on smooth roads, slightly dulling urban efficiency. These quirks don’t ruin the experience, but they’re worth noting.

Pros & Cons

Pros	Cons
Powerful 1500W peak motor	Heavy at 77 pounds
Long 60-68 mile PAS range	Limited throttle-only range
Full suspension for comfort	Rear suspension creaks
Strong hydraulic brakes	Dim headlight, no taillight
Durable 400-lb capacity frame	Assembly instructions unclear

What’s Included?

• Happyrun G50 Electric Bike (85% pre-assembled)
• 48V 18Ah removable battery with two keys
• Battery charger
• Front headlight
• Full fenders (front and rear)
• Rear cargo rack
• User manual and basic assembly tools

The package covers the bases well—I was rolling after some elbow grease, thanks to the tools and mostly clear manual. Fenders kept mud at bay during a wet ride, and the cargo rack handled a 20-pound load without complaint. The battery keys are a smart touch for security. I’d have appreciated a taillight or a phone holder for navigation, but what’s included sets you up nicely for varied rides.

It’s a well-tuned package, with room for polish in lighting and assembly ease.

Final Breakdown

9/10

The Happyrun G50 Electric Bike earns a strong 9 out of 10. It’s a powerhouse that blends thrilling performance with real-world utility—perfect for trail riders, commuters, or anyone craving versatility. The motor and battery combo excels on long hauls, while suspension and brakes keep you in control. Its 400-pound capacity and cargo rack add practicality, and the fat tires laugh at tough terrain. Weight, a dim headlight, and minor creaks keep it from perfection, but they’re small trade-offs for this level of capability.

If you’re after an ebike that tackles mountains or city streets with equal gusto, the G50 delivers. It’s not the lightest or cheapest, but its value shines through in power and durability. I recommend it wholeheartedly—charge it up, hit the path, and feel the rush.
