Nice! You're my hero! The Bulls is the 28mph w/ 500whr, but probably will mean less distance than yours... Getting some exercise during commute and dropping weight back down is the goal!
Excellent! I was on the fence about investing in a high-quality ebike; but soon after I got it I was regretting not diving in years earlier. I was drawn to the fatty since their frames tend to be beefier, and I wanted something that'd carry by weight without trouble. I also wanted a pedal-assist, no throttle: the goal was to get moderate exercise in my comfort-zone and not arrive @ work sweaty. The FatSix has fit the bill perfectly. You can have a look at my past posts...I'd had a few issues with it early on, but they turned out to be minor things that I could have avoided with some standard maintenance and a little better bike-knowledge. The FatSix is rock-solid...still is after 1000-miles...really high-quality hardware, and superb engineering. The only thing I can really complain about is that one of the Miranda crank-arms had a defective ISIS interface which evolved into another issue with a retaining-clip on the Bosch motor; this was all handled under HaiBike's incredible warranty . I really beat on it out of the box, and I should add that I regularly carry about 50 extra lbs of stuff in my backpack, so the frame handles about 330-lbs. just fine (or did...since it'd be 290-lbs now!).
I should add that although this model cuts off assistance @ 20MPH, I installed a chip to circumvent it, and it's worked flawlessly. This bike NEEDS to cruise @ 22MPH. Also, in my experience I've had very little need for the upper two assistance-levels (about 200% & 300% matching effort) VERY rarely would I use them on trail-riding where I'd hit an exceptionally steep section. In fact, after having ridden it regularly on its 2nd-level (100%) with a little more than 20-mile range...I've begun to be able to ride in its lowest assistance level (50%) very comfortably. This, of course, since I've become stronger. On a full-charge, I can get about 32-miles out of it in that mode.
Now, since we're comparable in size: this bike comes in 3 sizes, and the LARGE version is JUST large enough for us. I found that I needed to keep the seat-post at its absolute maximum-limit for a really comfortable ride. I ended up installing a 400mm dropper seat-post to save my balls on the trails, and it added a few mm to the max-height, so I'm in a real comfort-zone there. I also installed a handlebar extender which raises and pushes the bar about 10mm forward. Also installed some bull-horns on the bar-ends to allow me to recline a little when cruising.
One last note: this IS a fatty, so its fatter tires contribute a lot more rolling resistance, hence the lower-than-average range. This is directly related to the tires' pressure as well. That all said, it handles exceptionally well on sand and rocky beaches as well as snow. For regular, long-distance commuting, I would recommend investing in commuter-tires and high-pressured inflation...I'm getting over 20-miles per charge on the knobbies, who knows how many more you could get on slicks and asphalt.
