She wants a bike that works like her present one, but is lighter and better balanced. I think she has an old Woosh Crusa. Read post #1 to see what her problem is.
Yeah I did that originally, and thought I was giving info that would be helpful at least, or even that the suggestions were moved away from the general East Asian gas pipe special imports which are particularly heavy, and with the Crusa being 24kg, which is the weight of my full susser.
So something alloy, and again as i said, weight reasonably low down, or at least balanced more than having everything at the back- the Brompton is weight on front wheel, battery weight at the back, or the Ribble, which is rear wheel weight, with the battery int he down tube
As opposed to the majority of the suggestions which were not far off the Crusa format-battery rack, rear wheel motor, which i've found seems to over balance the bike that is only made worse when you add a pannier or two of shopping to it.
Then the conversation turned to sensor type, which to my mind appeared to be more about academics or sensor type rather than what Katy actually asked for- that being the parameters of her needs
You must admit you lot can go off in technical directions and possibly lose sight of what was actually asked for.
On that note I fully admit to not really understanding the types. My two bikes are Bosch, with whatever that uses, but is an instant pick up, and the Bafang with its BB mounted sensor, both of which are ok on my now older and far less power/springiness legs.
So from my scant experience of two types of sensor, I would think you either would need to have zero muscles in the legs, and i mean zero, or that Katy isnt quite understanding as to how much or little as the case is of what power is required to turn a set of pedals- keeping in mind of course that previously she rode the 50lb Crusa
I know a rider with one leg who can ride fine, so to say they are having difficulty turning the pedals seem off to me and if you were in that bad a state a disability scooter would probably suit better
I mean the mate is old and has one friggin leg, and still rides with a Bosch gen 4, so I cannot compute anyone with two legs being less able than that.
I've also got acute tendonitis in both legs and vascular issues in the right, meaning less oxygenated blood circulating those muscles, which as you can imagine means i wont be doing the tour de France any time soon. I should also add i have asthma and copd
Yet despite those disabilities can still ride ok
