New G300 Pro defective out of the box, “order # 31307”more than a week of troubleshooting I was excited about this bike. It arrived 10/15/26, I assembled it exactly per the manual, and it's been a frustrating experience since day one. Right away I hit three problems: the charger blinks red/green continuously and won't charge the battery to full (the manual only lists solid red for charging and solid green for full), the battery key wouldn't turn to ON with the battery installed, and the left pedal wouldn't thread into the crank. Three defects on a brand new bike before my first real ride. I contacted support the next day by email, text, and phone. The phone went unanswered and texts got scripted replies. Email support did respond and shipped replacement pedals and a battery lock, which I appreciate. The charging problem is still not fixed. I rode the bike about 12 miles to check the battery, and it powered the bike fine, so from what I can see the problem is the charger. Support says the battery could still be at fault, and told me other customers have reported the same red/green blinking where a replacement charger didn't solve it. So instead of sending a working charger or battery, they've asked me to test both with a multimeter. They offered to mail one, but waiting on shipping would have left the bike sitting even longer, so I ordered my own and I'm waiting for it to arrive. I'm not an e-bike technician, and I didn't spend this much on a new bike to become one in the first week. I've sent photos and videos and will send the test results as soon as I can run them. HappyRun offers a 30-day New Bike Guarantee, and I'm asking them to stand behind it with a fast resolution, including a replacement bike if that's what it takes to get me a working one. I'll update this review based on how HappyRun resolves it.

Hey there Happyrun, so you mentioned in your reply that your going to expedite the shipment. And also very strange is all the emails we have been sending back and forth are all of a sudden gone. You guys said you were going to get back to me on the 21st after some holiday or festival that was going on. And since all the emails are gone. What do I do now, I need to send motor back so I get my refund and then so I can purchase the correct motor Thank You !

The delivery date was wrong by 2 days. The frame is not aluminum it is magnetic which means it is some kind of steel. The phone number is for their warehouse in California and it is staffed with warehouse workers not sales or technical staff and their phone system is bad. The PAS might as well not exist it appears to do nothing when in modes 2 through 5 and a little resistance in mode 1. The bike is hard to mount and unmount. I do not believe it will travel 75 miles on a charge but I will attempt to find out.

The bike outta the box is not working. Error code 30 and I bought this bike for my daughter for Christmas and the fact that she still has not been able to ride it. It’s very disappointing. I contacted customer service put my order number in and I’ve waited. This is my third day and I’ve heard nothing back from the company. I tried to call them. Did not get any answer. I actually wanna put the bike right back in the box and ship it back. However, my my wife says I need to wait and get the company a chance. All the reviews were so wonderful and here I get the bike and it doesn’t work.Very disappointing for my daughter.

Not off to a good start. I have not yet received my g300 because I recently ordered it. However I have been trying to get ahold of customer support for 4 days now with zero response. Multiple phone calls and multiple emails with no responce! I was so excited to finally pull the trigger and purchase this model but the lack of customer service has really soured this for me and I haven’t even gotten the bike yet.
