Thanks, Gary. The Frey Fat Bike has pretty much all of the features I'm looking for: high top speed, fat tires for comfort, mid drive for any off road riding, multiple frame sizes, full suspension and.... a rear rack! Even the crank arm length of 170 works for me. Apparently Frey is shipping individual orders in wooden crates which is pretty cool.
My lone concern is probably the Q factor. I'd also like a frame integrated battery as well as I am reading reports of some Frey riders velcroing the battery to the frame.
I certainly don't need 4.8" tires. I'd be just fine with plus sized tires. If that's what it takes to get the Q factor in line so be it. But I still want dual suspension with a rear rack! Compromises will have to be made somewhere along the line, obviously. But the Frey Fat Bike is a darn good starting point and very near an exemplar of the type of electric bike I'm looking for: fast, comfortable, and useful for everyday errands.
I haven't really given much thought to how practical a 100 lbs bike might be. 70 lbs bike, a few pounds of accessories: lights, fenders, reflectors, panniers, and add to that 20-30 lbs of groceries or anything else from a store run.
The 'gold standard' for me would be the Frey fat bike with 2.8" tires, 170 Q factor, frame integrated battery, weighing in significantly under 60 lbs bone stock. Ivy, are you listening?!?
