how long are the connection starps for the large bag? I have an ebike so the lower tube is very large because it has to house a battery

The straps are about 4-5 inches

Can this bike frame bag accept (in its opening) the kryptonite new yorker lock (4.5 lbs., ~ w 6.5" x l 9", 16mm thick) and a bundled 6' long cable?

Yes, this bag can hold that and more. Just for example, we transported 4 20oz Soda bottles and 2 bags of souvenir t-shirts in it and had enough room to probably carry twice as much as that but it would be awkward pedaling that bulk.

Using a 3 liter bladder inside the pack, is the frame pack designed so that the bladder-in-pack does not interfere with the pedaling motion?

There are 2 or 3 straps per 3 sides of this pack, it is fixed in the frame. The sloshing of a portion of maybe 4 lbs of water shouldn't be noticed whatsoever.

I have a thick down tube on my mountain bike. How adjustable are the velcro straps for the down tube and will it fit?

Okey upon ur request I have taken the measuring tape and measured all the Velcro straps on this moosetrek bag and all the straps from one end of strap straight to the other end of opposite side strap is of 12 inch wide, including the bag width between the connecting strap, Hope it helps. Rest assured it’s quality made bag after returning few expensive bags.
