Is there any benefit to an inframe battery?

I can only see negatives:
1) charging can not be done separately from the bike.
2) you cannot get a second spare battery for extra range
3) when the battery eventually needs replacing, it will be even harder to find a compatible one.

The only plus: it looks a slight bit more streamlined.

Does it really seem that odd to differentiate between two biologically distinct classes of people who, on aggregate, differ greatly physically in terms of height, weight and proportions? The anatomical differences you mention (assuming you’re thinking of “bits”) are the least of it. The average British man is about 5’9” and 13 1/2 stone; the average British woman about 5’3 1/2” and a touch over 11st. (NHS 2019).

So yes, of course a man can ride this bike -a man average or above in height or weight might find it a tad small. If you’re an average woman looking for a bike, it wouldn’t be particularly helpful to be shown a load of bikes built for the average male body. You might well give up trawling through and go to another shop where their bikes are helpfully categorised based on what is overwhelmingly likely to be suitable for you based on your physical characteristics. So, while there may be some overlap - many men who could happily ride this bike, and vice versa - it makes commercial sense to break them down into “men’s” and “women’s” models. Hope this helps!

250W is a legal limit isn't it? It should be OK on hills too if you help. It is a bike after all.

Any thoughts yet, range etc..

Why do you prefer that one more please (new to these)
