I'm a petrol-head at heart. Not by inclination, just by 40+ years.
So when I came to ebikes, I admit that I expected the battery to behave a bit like a fuel tank - fill it, use it, refill it, and so on.
I wasn't expecting a 1/4 full battery to behave any differently from a FULL battery, just to have fewer miles left in it.
Ok, I have learnt (a little) since last year.
But what I would like guidance on is this: eventually, I know, my battery will stop functioning altogether. But what are the symptoms of battery decline? Will it always be as zippy when first full? Will it just do less miles between charges? Does the '2 year' rule of thumb for battery life hold water, or can you shorten the life by frequent charging, or by (say) heavy throttle use, and by a heavy rider?
I ask as after 900 miles/9 months my Wisper SEEMS to be a little less willing than it was. I have a series of bench-mark hills which I use to assess the general fitness of me/battery, and even though the weather is no longer a factor (reasonable temperatures), they feel harder... or maybe it's just my perceptions changing. Not 100% sure.
(Like all Wisper owners I do have a standing invitation to take my bike back to my dealer; it's just that I can't really face stripping it down so that I can cram it into my smallish car, ploughing through 50 miles of London traffic (each way, and possibly on two successive days), so I'm taking the lazy route first and asking my fellow ebikers!)
