Disabled cyclist; with one bad choice behind her, needs help with a new bike

"Lightweight bikes are available but these tend to be sportu road type bikes with minimal battery size and small hubs for the fitter rider who usually only wants light assisstance now and then"

this is a missed market, the disabled rider, the older rider, the smaller rider even the pregnant rider need light weight bike - it's about wasting energy for the rider with a chronic illness

My daughter riders everywhere, but when she was pregnant, when she is travelling home from a performance/dance show she just wants to whizz home (not speed just ease/lack of effort)

Your needs are more niche than hers. In addition: more even weight distribution and larger wheels than your Cruza, and it must be step through. I can't find a reasonably priced lightweight step through bike or bike frame (custom built titanium would be too expensive) which can have a middle-ish mounted large capacity battery easily fitted, for an overall lightweight rear/front hub cadence sensored conversion, which would be lighter tham mid-drive.

More powerful bikes have heavier motors. Longer range bikes have heavier batteries. Beyond a certain point (10-11 kg ) reducing the weight of the non e-bike specific components is chasing diminishing returns. The lightest conversion kit I've fitted had a 1.6kg AKM 75 motor and a 1.8 kg 36v 10Ah bag battery but isn't massively powerful and doesn't have a huge range if you use all the power.

That's the beauty of building a bespoke bike, you can choose what's important to you and fit a conversion kit to suit, but if you want lots of power and lots of range using that power it's not going to be light

A trike would be heavy as * so it won't increase my mobility & now I can't even open the sodding car door, so driving will only work if there is someone there to let me out ffs

This is worrying - are you sure you're still strong enough to control a bike? If you're no longer safe cycling, perhaps it's time to start a thread asking which mobility scooters are easiest to hotrod? Increasingly popular with able-bodied people. At times I'm tempted to hotrod one myself, usually when swiftly overtaken walking on the pavement by one whizzing past at who knows what speed, and annoyingly they never ring a bell or beep. Looks fun.

The two requirements of high power and lightweight are conflicting characteristics. It's not that somebody's missing a market, it's that physics prevents it.

A bit like building a house. You can have a good house, a cheap house and a quick house. But only two of those three.

This thread has been going for over a year now plus the previous thread of the bike her brother built for her with the specs to suit himself.
Cat is looking for the nirvana of ebikes wihich doesn't exsist for a rider with debilitaing health issues or a movement disability. Typically one has accept there will be constraints and not think of being in one's prime when these health issues may not have exsisted or been so prominent.
A trike or legal twist and go seem the probable route

It has all been said . One can't have power , long range in a light weight bike.
The focus does seem to be a tunnel vision view all etched on an unsuitable style of bike system of a torque sensing mid drive bike . Which all in all has all been drawn out and discussed now many times , to which the answer from most is that this is just the wrong bike system for said such use with the underlying health /mobility issues.
