Love this bike. Great quality!

Worked perfectly after assembly. No problems. Lots of fun

High Quality Bike

I just got ebike last week,and this is bigger than I expected.but so comfortable.

I suggest for any fat butt like myself!

I love it! Once I got that seat pitch set right it was great.. I suggest for any fat butt like myself!

The bike is great

I had the chance to get this bike and wanted to see what the hype was all about with fat tire ebikes. After a quick assembly and charge of the battery, I was ready to ride. The monstrous 26" fat tires can go over anything and aided with the front hydraulic shocks makes for a smooth ride. Top speed is 22mph and range seems to be excellent. My only complaints is the bike is so big that it's hard to transport and the grips are on the harder side. Otherwise this is such a fun bike to ride and to challenge yourself on new trails.
