Kev, not tested it - but I can't imagine a Nexus 7 with coaster brake would play very nicely. In addition to this, my freind's bike that i fitted Bafang mid to has destroyed two Nexus 7's due to torque.
OK thanks, that's useful to know. I have been advised that before, I think by Jamie at SBC, that the Nexus 7 is an older model and doesn't take nicely to the additional stresses. I want to get rid of the coaster regardless of whether I go electric or not, and put a disc brake on the back.
If you want to get electric without cost of replacing what's installed you could get a front hub motor. I'm in the middle of installing one myself with derailleur gears.
Thanks for the tip, but I'll likely just be going with whatever Besbike offer. I struggle to find the time to fix a puncture, never mind doing something like the above. I understand I'll end up paying a couple of hundred quid extra doing it via a shop rather than anything myself, but it's the time is the problem.

Nexus 7 isn't a great hub, lots of drag, tend to explode for no known reason even when only a few weeks old.
Nexus 5 is very solid so long as you do not smash through gears whilst putting power down/mid drive is driving.
Nexus 8/Alfine 8 of the last generation or so is still a good hub, unless you go for a Rohloff or Kindernay (both of these are the kings, but also £££).Bullitt stock rear wheel whether the more basic flat profile rim or alex supra is a very good rear wheel. 2020/21 they had some bum spokes get into some stock. The rear hub is a novatec, but its their biggest toughest freehub style 135mm hub, thick flanges, big bearings x 4, 6 pawl freehub. Mine has 5000 miles of abuse from customers, rentals and from myself, lives outside most of the time, had to re-grease it once, bearings are all still perfect. Have had some folk basically DEMAND a high end MTB hub instead, so have built second sets of wheels onto Hope, Industry Nine and DT hubs. None have lasted as long (hopes the flanges on the rear actually crack under the load/gauge of spokes being used).
Less can be said of a few hubs that some other brands are stocking on their bikes at this price point (saw a £20 rrp shimano QR hub on one the other day, no name + regular gauge spokes and a no name rim, on a £4k~ bike!!!).

I've read that you can disable the coaster brake on nexus 7 but it seems like a bit of a faff. So just install hub motor and hold out til a good alfine 8 or similar comes along 2nd hand?
