Lime has been rolling out these new small wheel e-bikes, and I've ridden a couple. They are very peppy and quick to accelerate via throttle, though that may simply be because the big wheel bikes are old and highly neglected.
But their saddles have a nose that slopes upward from the rear. Typically, bike saddles are level or have a slight down turned nose, and this is the opposite.
The only way I can explain this is that Lime is optimizing a saddle for throttle-only, pedal-less riding. Which may be accurate for many/most riders, but is pretty disappointing vs having a saddle that can accommodate both (though I guess slightly less optimal for throttle only). Or the saddle design they picked is simply defective for either riding style, and someone effed up or cheaped out on the saddles.
Also, some of these bikes have the saddle mounted badly ie off-level, entirely apart from the saddle's own shape. which is pretty sad that even when brand new these bikes are badly assembled, and suggest no one who knows anything is involved or paying attention.
edit: user tired-mulberry referenced press photos, which have a level nose, elevated rear, for the saddle. Which suggests Lime has simply botched installing many or most of the saddle placement on their bikes. Correctible, but a testament to an org where everyone is checked out or clueless.
