I am in a similar position to ammonite - looking for an e-bike that can cope with the numerous hills of Swansea plus able to help ride into the often frequent headwinds on the Swansea foreshore cycle path.
I also want a rack of some sort so that I am able to carry my pannier bags / shopping. I would prefer some form of trapeze or step-through frame as, despite being a 33.5 inside leg anf 6 foot tall, I find it easier to step through the bike when mounting and dismounting. I currently use a Specialized ladies non e-bike as a shopping bike and, ahem, not having to get my leg over the rear rack and pannier bags is a joy.
The hills around Swansea are numerous and varied - long and steep, short and steep, long gradual climbs, etc. I noticed that Tredz uploaded a video on youtube a few weeks ago of one of their staff riding a Raleigh Motus up Constitution Hill in Swansea - I have seen pro racers collapse on that hill. Talking with the staff they loved the Motus but it seems expensive compared to some of the Cube e-bikes which appear - to my inexperienced eyes - to have better kit for the same money.
I see more and more e-mtbs in Swansea and wonder whether people are opting for them because of the power they give for the local hills. But none have racks and panniers on them so they are not suitable for me. I am not a fan of seatpost mounted racks.
Rant over.
