Hello!

[Woosh]

How much would a 26" wheel with the motor hub built in, the 17AH battery, and any cables and controls weigh? (£599, wasn't it, for all of that?) I haven't weighed the bike, but I'd guess that it is about 13 kg. If so, it should be possible to convert it to an ebike weighing about 19 kg?

the motor weighs 1.9kgs on its own, battery + controller 3.1kgs, cables + LCD about 300g.
the total bike with all the electrics would weigh about 19kgs.
