I bought this bike for our son and he absolutely loves it. The quality is excellent and it runs really smoothly. It feels sturdy and well built, and we haven’t had any issues with it so far.

Great bike! My son loves it. Solid construction, great torque & fast! Customer service has been incredible! Easy to reach and fast response back. Very happy!! This bike has the peddle control making it legal for street riding in our city. Police department confirmed. His friends Sur-ron not so much.

    • Slow customer service, but reliable.
Color: black
******ATTENTION ATTENTION ATTENTION PLEASE READ****** This "e bike" is no longer street legal and should be labeled as an electric motorcycle, due to new state and federal laws, the motor is over 750 watts requiring it to be registered at the DMV as such meaning you need to register it, get a license plate and have insurance. There is a way to get it done. It is very difficult and expensive though. Since Happy Run doesn't issue a Manufacturer Certificate of Origin or Statement of Origin. This vehicle does not have a VIN. DO NOT PURCHASE UNLESS YOU PLAN TO ONLY USE ON PRIVATE PROPERTY. Check your states laws and requirements for requirements for trail riding or registering it as an off highway vehicle. Happy Run company has completely negligent and unhelpful with my multiple requests for proper documentation and Amazon has not been helpful either because Happy Run is a 3rd party seller. PLEASE CHECK YOUR STATES LAWS REGARDING NEW CLASSIFICATION OF E BIKES THAT WENT INTO EFFECT ON JAN. 1st 2026 ... show more

    • Smooth ride!!!!!
Color: black
I purchased this bike and I've had it about a week and I'm surprised by how comfortable riding it is smooth and suspension is. The acceleration caught me off guard definitely an upgrade from my prior bike. Assembly wasn't too difficult it took me about an hour and a half. I forgot to put in my free phone holder however when I reached out to customer service they responded promptly and were friendly. I would definitely recommend this bike to a friend. ... show more

    • Great bike so far
Color: black
Very fun bike and half the price of a surron. It accelerates very fast and holds its speed decently although once it hits 40mpg it seems to take longer to get to 50mph (I haven’t hit it yet you need a very long stretch of road). It doesn’t have a full handgrip throttle, but the half is decent. My main issue: the battery seems to be a little cheaper (for its output) and tends to flicker the head lights from time to time. Sometimes the power glitches out a bit on startup but it may just be my bike. The connectors aren’t the best quality and can bend inside. ... show more

Order this happyrun G pro300 for my son‘s 13th birthday. He was very excited delivery got fast within 4 working days. He drove this bike like crazy every day everywhere he put like 300 miles within a month and a half on this bike just riding around and then we had an issue with it because they were doing some wheelies and I don’t know how but they burn the hub motor ,email the Customersservice it was very easy to get the service so quickly send the email a couple of days later. They said they already shipped the part for you and the part was here. It’s the whole new hub-motor. We are very satisfied with the service and the product , and whatever they say is 50 mph it gets 50 miles on a ride battery deplet fast on the high speed but still he gets like 59 -60 miles on a single charge , the price is good , built is good too compared to to other big brand over all my sons love the bike he goes to school on it and it has the paddle too ... show more
