I like the look of the pendix kit expensive tho – well over £1000 iirc. Mid mount and torque sensing

£1699rrp (£50 more for the Brompton one which I’ve ridden briefly and seemed to work nicely)

CYC-X1… Wow. 3000w. I thought that the legal limit on power was waaaaay less than that.

Talking about build quality though, my mechanic and I were discussing that the other week and he is horrified at the poor choice of materials on the cheaper end of the pre-built systems. His opinion is that they are just taking normal bikes and components and then bolting heavy torquey things to them and selling them for a grand. The state they get to because of the unusual wear and tear is phenomenal apparently.

That Bafang mid-drive thing looks really well put together though, nicely integrated.

For the UK it is if you want to be raod legal – its 250w. Its 1000w in the us IIRC so that motor I doubt is legal for road use anywhere unless you register as a motorbike
