Just home from two weeks in PNW islands that included Victoria, Sydney, San Juan, Salt Spring, Whidbey, Lopez, Port Angeles, Port Townsend and Squim. Rode with no main battery but with one or two range extenders in my bottle cages. Assembly was different to some degree than a coupled S&S travel bike due to Future Shock concerns when removing fork and dealing with hydro brakes, but a little practice before made it no more challenging than my S&S. I did remove the Future Shock and replaced it with a rigid dummy available on ebay.
A top cap with an M6 bolt is needed for the top (included) and if a lower stem position is used, the part can be cut to length and a normal star nut and top cap can be used. Part weight with the top cap and bolt is 110g, 239g less than a Future Shock 2.0.

A little wobbly when full and dealing with a crammed SeaTac Airport zoo but the case has a bunch of handles for pulling/carrying and well-done protection within the case and extra tube protection pads included.
TSA did not bat an eye at the two extenders in my carry on day pack and on Alaska Air the Post Transfer went at the normal bag price of $35.
Rode with the motor on a lot and averaged about 30-35 miles and 2000 feet before an extender pooped out. Takes 2 minutes to change from one battery to another. A wonderful way to do a tour at my age...or any.
