Hello everyone! Really grateful to have found this thread towards the end of a long time researching into / dithering about an e-bike. Everyone's comments have been really helpful to me; I've appreciated the photos too, both the ones in the wild and the ones going into those parts of a bike that you just don't see on manufacturers' / retailers' websites or in commercial reviews.
It's usually invidious to pick anyone out for special thanks in these situations ... but I'll give it a go. So thank you especially to
@goo_mason @richtea and
@gzoom for so many words and photos of wisdom; and to
@Mandauk40 and
@Notxal for their photos. You were very helpful.
I've ordered on the
Halfords website an ADV 8.9e, a spare Fazua battery, and an empty battery compartment cover. I collect the bike "built" from my local Halfords in eleven days time. Yippee!
I've also spent a long time looking in my shed at torx sockets that will fit on the end of a small torque wrench. I was also pleased to discover that I had a small screwdriver set, purchased years ago in Lidl, that has a choice of torx heads! The first job will be to check that the bike has been "built". And then check that the firmware is up-to-date, I guess.
Other stuff - saddle, pedals - I know I've got. I'll want to fit mudguards (thanks for the advice and photos) and a pannier rack. I'll give the bike a few miles before deciding on better bar tape.
So many, many thanks!
P.S. I read somewhere, possibly on the CTC site / forum, that I can reduce the gearing further by swapping to a Sunrise 11 - 46 cassette (with a longer chain). Does any have any thoughts about this?
