What It's Actually Like to Ride
Specs tell you what a bike can do. Riding it tells you what it feels like. Here's our experience across three real-world scenarios.
0-30 MPH in ~4.2s
First Ride Impression
Twist the throttle in Class 5 and the G300 Pro launches forward with immediate, violent torque. The 120Nm motor pulls from zero — no turbo lag, no hesitation. At 50 MPH on a fire road, the bike feels planted and confident, the full suspension soaking up whoops and bumps that would rattle the teeth on a rigid bike.
70+ miles per charge
Urban Commuting
Switch to Class 3 (25 MPH) and the G300 Pro becomes a capable urban commuter. The hydraulic brakes modulate beautifully in stop-and-go traffic, the 2000-lumen LED headlight cuts through darkness, and the 70+ mile range means you only charge once or twice a week. The 31-inch seat height requires confidence at stoplights, but the wide handlebars make low-speed maneuvering easy.
120Nm torque
Trail & Off-Road
On technical single-track, the G300 Pro's weight (136.8 lbs) is noticeable but manageable. The inverted front fork with 80-120mm travel and rear monoshock absorb rock gardens, roots, and whoops without bottoming out. The knobby 70/100 tires grip loam and hardpack with confidence. In sand or deep mud, the 6500W motor and 120Nm torque pull through where smaller bikes would stall.
Pros & Cons
No product is perfect. Here's our balanced take on what the G300 Pro does well — and where it falls short.
What We Love
- Best price-to-performance ratio in the 50MPH class
- Removable 72V 30Ah battery with fast charging
- Full suspension with adjustable front fork
- Hydraulic brakes with oversized rotors
- 5 speed modes for beginners to experts
- IPX5 waterproof for all-weather riding
- 2000-lumen LED lighting for night riding
- 14-day trial + 2-year warranty
What Could Be Better
- 136.8 lbs is heavy for a single-person lift
- 31" seat height may be tall for shorter riders
- No street-legal lighting package (turn signals only)
- Charging cable not included in some regions
- Color options limited compared to entry-level models

Everything you need to know about the HappyRun G300 Pro. Can't find your answer? Reach out to us at support@happyrung300.shop.
The G300 Pro reaches up to 50 MPH in Offroad Class 5 mode. In City mode (Class 3/4), the top speed is limited to 28 MPH for street-legal riding. The bike has 5 adjustable speed levels, letting you dial in the perfect pace for your skill level and riding conditions.
HappyRun rates the G300 Pro at 70+ miles per charge, tested at PAS level 1 with a 165lb rider on flat terrain. Real-world range varies based on rider weight, terrain, speed mode, and throttle usage. Expect 40-55 miles in mixed riding with occasional full-throttle bursts.
A full charge takes approximately 5-6 hours using the included 84V 5A charger. Fast-charging capability gets you to 80% in about 2.5 hours. The 72V 30Ah removable battery can be taken off the bike for convenient indoor charging.
Yes, the G300 Pro is an excellent choice for beginners. Its 5 adjustable speed levels let new riders start slow and build confidence. The electric powertrain is quieter and easier to maintain than gas bikes — no mixing oil, no kick-starting, and no warm-up needed. The full suspension and hydraulic brakes inspire confidence on uneven terrain.
The G300 Pro arrives 80% assembled. The package includes the bike, battery, charger, battery keys, basic tools, and an owner's manual with a QR code linking to an assembly guidance video. The battery, charger, and pedals may ship separately via FedEx with their own tracking numbers.
The G300 Pro is designed primarily for off-road use. In City mode (28 MPH), it has a headlight and taillight, but it lacks turn signals, mirrors, and a DOT stamp in most configurations. Check your local DMV regulations before riding on public roads. Some states require registration and insurance for electric motorcycles.
HappyRun offers a 2-year limited warranty covering the frame and key motor/electrical components. Additionally, there's a 14-day trial period — if you're not 100% satisfied, you can return the bike (restocking fee applies). Free shipping is included for all continental US orders.
The G300 Pro weighs 136.8 lbs (62 kg). The battery pack alone weighs approximately 30 lbs. While manageable with two people, lifting it onto a truck rack or loading it into a car trunk may require assistance for one person.
Yes, the G300 Pro features a removable 72V 30Ah lithium battery. The removable design lets you charge indoors or carry a spare for extended trips. The battery key is included in the package.
The G300 Pro has a 31-inch seat height and is recommended for riders between 5'1" and 6'5" (154-196cm). Riders around 6'0" can place both feet flat on the ground when seated. Riders closer to 5'1" may need to slide forward on the seat for full ground contact at stops.
