I recently purchased two HappyRun G300 Pro e-bikes, and I couldn't be happier with them. They are excellent bikes and have been an absolute blast to ride with my kids. We've already put a lot of miles on them, and they've performed great. I had only 1 issue, but HappyRun's customer service was outstanding. They responded quickly, sent me a replacement part without any hassle, and had me back out riding in no time. It's refreshing to see a company that stands behind its products and truly takes care of its customers. Between the quality of the bikes and the exceptional customer service, I would highly recommend the HappyRun G300 to anyone looking for a fun, reliable e-bike. I'll definitely be purchasing from HappyRun again when the time comes. ... show more

I really like this bike. It's an attention grabber. Really don't need to use your pedal assistant. I took it up to 42 mph. A friend of mines took it to 50 mph. This bike is a great value for this price.
