Add the essentials we recommend with your HappyRun G300 Pro 72V/30Ah 6500W Off-Road Electric Dirt Bike.
So far it has been good. Assembly went smooth. The tools were decent that came with. Shipping was normal speed. Quality of the bike is great so far. I’m 6’3” and weigh 250 and I hit 49mph on the bike so far.
I recently bought a HappyRun G300 that had an issue and needed to be exchanged for a replacement. Throughout the process, I was extremely impressed with Watt Wheelz customer service. Many other merchants would have just directed me to the manufacturer and wished me 'Good luck,' but Watt Wheelz actually stepped up. The new bike is great, and I am completely satisfied. They responded to emails within hours and kept me informed during the whole process. They really advocated for my case with HappyRun. They earned my confidence, and I recommend Watt Wheelz without hesitation to anyone wanting to buy an e-moto!
The Happyrun G300 Pro has been great so far — powerful motor, smooth ride, and a really solid build. It handles rough roads easily thanks to the fat tires and suspension, and the battery life has been reliable. Shipping didn’t take too long and the bike arrived on time. Overall, it’s been a fun and stable ride.
Great priced for what's on the market today. Packaged perfectly. Very simple assembly. Functions as should. Happy with my purchase. ThanX MuchO
This is one of my favorite e-bikes that I own Good quality, whisper quiet and great customer service
I put 150 miles of Smiles with my new G300 pro last week. Such controllable POWER. The suspension is awesome you could ride across a cow field at 40mph super smooth. Thank you happyrun, you filled my life with purpose again. 😎
Great power and styling look! You have a hard time telling it’s not a motocross bike. Smooth power and comfortable ride.
I usually don't write reviews, but I'm a real buyer and I had to share. Great service from WattWheelz. There are too many fake e-bike stores out there, but WattWheelz is 100% legit. They actually answer messages! I love the G300—solid quality and great for both urban and off-road riding. It definitely hits 50mph, which is fast for this price point. The pedals make it much less attention-grabbing in front of officers, and it's super quiet compared to the Talaria XXX. Thanks WattWheelz for a great buying experience!
The bike is exactly what they promise. This thing is fast and fun. I use it not just for fun, but also as a daily commuter to work. I cannot believe how nice this thing is for the price. You can certainly make upgrades if you want to as well. The customer service has been fantastic. They’ve gotten back to me quick and easy with solutions. I would recommend you buy this bike.
Amazing unit. No downside. I feel 20 years younger riding this
I really hope that the g300 pro last a long time, because this thing is great! I got the extended 3rd party warranty. So if anything happens to it, it should be covered. But so far so great 🤘
Coolest thing I’ve ever bought need at least 2 more for the family
Fantastic! The bike and customer service the entire experience has been nothing but Fantastic! Love it! Thank You Watt Wheelz...!

It is the pinnacle of my adulthood! Bike is fast good for charge and super fun. Got pulled over and it passed as a bicycle so that's an even plus! Get one. this is it don't look further!!
Grabbed the 2025 HappyRun G300 Pro a few weeks ago wanted Sur-Ron/Talaria vibes without the crazy price.
Hits hard: 6500W peak, instant torque, rips to 50 mph fast. 72V 30Ah battery delivers 60–70 miles mixed riding, 40+ when I’m full send. Upgraded inverted forks + rear shock eat up rough trails like nothing. Strong hydraulic brakes, no fade.
Feels solid,beefy frame, clean digital dash. Took 45 min to assemble.
For the money, it’s a no-brainer. Fast, capable, ****** fun off-road. Already hooked—big trail days incoming.
Shred on 🚀
Wagwon bossy Im a big guy 6’3, 305 pounds i was worried before the bike got here of how it would get me around. I put 120 miles on it in the first week with a top speed of 43 mph. Thats perfect for me mon. BOMBOCLAT I have ridden it 23 miles on one charge so far and still had 3 bars of battery left as long as you stay in modes 2 and 3. Buy ittttt bloody dread head
I have been very happy with the bike. It performs well its fast and has all the features I need to commute with it. Looks cool. Handles well. I would definitely recommend it to others.
My son LOVES this bike. Hes 14, about 5’6, and he’s on the lower end of fitting on it. Lots of room to grow. Its fast but also easy to ride. Awesome purchase!
The bike is so fast and the seat is very comfortable for long rides. I would recommend it to anybody who not trying to spend an arm and leg on an E bike.
Best price,good customer service, shippings free and comes fast
Since being diagnosed with cancer getting this bike has given me such a feeling of freedom and pure joy. I get to ride myself to scenic places to just sit and be thankful for life. I wish i could afford one for my wife to ride but we are seniors so income is limited. It was a struggle purchasing this bike but we did it and i love it. Thank you Happy Run for making such a great ebike and for giving me the ability to see tge beauty on my trail rides.
Everything about this bike is worth the very good deal it was in the first place.
Awesome Bike and quick shipping!!
