Collection: Rooder EU warehouse

My husband and I bought this bike in a spur of the moment decision. He bought a different bike a few weeks prior and I really enjoyed riding his and also wanted to be able to ride right along with him. We decided on the HAPPYRUN G50 for me because the price is very hard to beat for everything you get with this bike! The 7 speed Shimano gear system allows me to pedal if I feel like it and the motor kicks in right away to give me a boost (my husband's bike is alot faster with more torque, but this G50 does a great job keeping up.) The rear turn signals are a great feature although they are not super bright so they are difficult to see during the day. I was worried the seat would sit to high for me as im 5'3", but it fits me great! We get so many compliments on this bike when we are out riding and have had no problems with riding on the side of the road or on bike trails. It is a great beginner bike and I would recommend it to anybody just starting out in the E Bike community or someone who wants a nice cruising bike without breaking the bank!

I’ve never ridden a dirt bike before. The GT600 has a beginner mode that limits speed to 20 mph. I learned on flat grass fields in Ohio for an afternoon, then slowly worked up to trails. The full suspension made mistakes less painful. A month later, I’m climbing hills I never thought I’d attempt. The free phone mount held my navigation app securely.

I ride trails in the Florida panhandle that are often wet and muddy. The GT600 handled puddles and light rain without any electrical issues. The 72V 30Ah removable battery let me take a spare on longer rides. The hydraulic brakes didn’t fade even after miles of mud. The electric air pump is perfect for adjusting tire pressure between sand and hardpack.

I took the GT600 to Moab, Utah. I pointed it up a rocky incline that I wouldn’t have walked up. The dual suspension and 7500W peak motor clawed to the top without slipping. The full-color LCD display showed my speed and battery clearly even in bright desert sun. The included phone mount held my GPS securely over bumpy terrain.

I’m a big guy in California. Most e-bikes feel small or underpowered under me. The GT600’s high-carbon steel frame is solid, and the 7500W peak motor pulls me up steep fire roads effortlessly. The hydraulic disc brakes stop hard even on loose gravel. The free lock gave me peace of mind when I stopped for lunch on the trail.

I used the GT600 for deer hunting in the Upper Peninsula. It’s silent, so I didn’t spook any game. The torque pulled me up muddy logging roads without struggle. The 60-mile range got me deep into the woods and back with battery to spare. The NFC unlock is convenient when my hands are full with gear.

I ride in Arkansas. The GT600 climbs steep, rocky trails that my old gas bike complained about. The 50 MPH top speed is real, and the full suspension handles rocks and roots like a dream. The battery lasted a full day of exploring. The free phone mount and air pump were ready to use right out of the box.

This is definitely one of the best purchases I've ever made. Seriously! What a beautiful scooter, I love it so much. There were just a few minor adjustments I had to make to get it the way I wanted it, and I'm very proud to present my Ronzlla RZ2 Version 2.0 Hahaha 😀

Quick and fast shipping, product worked perfectly

I had a question about the charger LED lights on my GD83. I emailed support and got a human reply in 3 hours. They even sent a short video showing normal behavior. American support matters. The scooter itself is a beast.

I got stuck in moderate rain for 20 minutes on my GD83. The display stayed dry, brakes worked fine, and there were no electrical issues. Still perfect a month later. I don’t worry about sudden showers anymore.

I’m 6’5”. Most scooter decks are too short. The GD83 has a long foot platform and tall handlebars. My knees clear everything. The 440 lb limit lets me haul groceries for my family of four. The ride is stable.

I ordered the GD83 to Chicago. Shipped from Nevada to my door in 72 hours. Came 90% charged. Hit 48 mph on my first straightaway. Build is tank-like – no rattles or wobbles. The turn signals are bright.

I bent a rim hitting a curb in Orlando on my GD83. I emailed support Monday night. A new quick-release wheel assembly arrived Thursday. I swapped it in 8 minutes with no tools. Insane.

I’ve owned three premium scooters. The GD83 climbs better and doesn’t lose power when the battery drops under 40%. Real-world 45 miles at mixed speeds in Denver. The hydraulic brakes stop on a dime.
