We love it when an independent ebike reviewer covers one of the bikes we carry. Check out the review of the Extreme by our friend Brent McCluskey from Electrified Reviews. Brent says:
"This is a folder with some attitude, and honestly, it’s just a great ride all around. We’ve reviewed quite a few electric bikes from Green Bike and this company does an excellent job at picking and choosing the right components. And the Big Dog Extreme is no exception. This folding electric bike is powerful, fast, compact and perhaps most importantly, it’s comfy." Not bad!
Here's a video of the ebike being unpacked and assembled. Super easy.

Hi I just bought a Big Dog extreme from your store, I am 6'4" and need a longer seat post. My knees are really close to the handle bars as well... I have the handle bars as high as they will go... Do you have any suggestions? Ted.
Thank you for your recent purchase. There are a number of long seat posts that can fit the Extreme, just make sure to select the 30.4mm diameter post. Here is an example of a product that would fit: https://www.amazon.com/GANOPPER-Seatpost-Aluminium-Adjustable-30-4%C3%97450mm/dp/B07PZ1GRQW/ref=sr_1_1?dchild=1&keywords=long+seatpost+30.4mm&qid=1591224785&sr=8-1
What is the step over height

WOW, I did all my research and limited my search to TWO different brands of folding ebikes for my Geocaching adventures. At least I thought I had it down to two models, till I fortunately stumbled upon the GreenBike Big Dog Extreme information. Now, I see this is the lightest model between all three, more power than the other two, more free accessories and still within my price points. I will try something really silly and email this company on July 5th, surely they wont respond. Ooops, bad call, not only did Steve respond, he answered my question, conquered my objections and I bought a new Ebike. This company is amazing so far, hopefully, they will continue going above and beyond with sales and constumer service.
I was in need of a nice folder that I could keep in my trunk and I stumbled upon this Big Dog Extreme from Really Good Ebikes and it turned out to be perfect for my outdoor needs. This ebike ticks off everything on my list and the long-range battery is a big plus.
I just received my new Big Dog Extreme from Greenbike and I have to say, so far it does seem live up to its name. The first thing I noticed was the power on this bike, and I can't wait to get on some trails with this Dog.
