Hi - I'm looking at the Greenbike USA GB5 500 on amazon. I don't even see this brand in the brand section of this forum and also didn't find any review on it here. It has great reviews on amazon (none for the 500 but for the regular GB5) and seems perfect for me. I just started looking at ebikes and honestly don't have a lot of time to travel 75 or 150 miles to visit a bunch of bike stores if I can avoid doing so. So I'm wondering if anyone has any experience with this brand and this bike in particular. Thanks!
