Yeah there's no question, the FX is the more practical and economical choice.
My point is that the cake fits a niche for someone who specifically wants something significantly more lightweight. And yeah, I was looking at the offroad, because personally I don't feel like most people in this niche are buying the CAKE as a commuter.
The whole appeal of the cake is being way more lightweight for trail riding, and on the street I don't think that offers any benefit except you have to worry more about someone throwing it into a pickup truck and stealing it while you pop into a shop for a few minutes.
Again, I think the cake specifically appeals to someone who is looking for the in-between space of a full electric motorcycle and a mountain bike. Plenty of people spend 5-9k on their mountain bikes that are merely pedal powered! It's very niche and only people in that niche are going to find value in the cakes pricing. The average person looking for a well-rounded emoto isn't really the target audience. For that, in that price range, Zero is pretty much the only option, at least until KTM has a street legal version of the Freeride E-XC. (238lb, btw)
Now the OSA+ and OSA lite I truly don't understand. Purely a fashion piece that doesn't seem to bring any particular value to its price point or market segment.
