@superfluous9726 even 20hp which is about the power on a highly tuned sur Ron, on a bike would be impossible to use without wheeling, riping the chain, destroying the wheel, etc
basically the whole bike/motorcycle has to be designed around the power/torque/speed and wouldn't be very different than current evikes or electric motorcycles.then once you account for the battery weight that is maybe at least 60/70% of the power rain weight, the gain is not that big.
then you also have to consider the gear reduction fora 10krpm motor going for instance 50mph top speed, you need around 1:20 gear reduction and the gearing starts to be heavier than the motor itself.
there is still potential for high power density motor in ebikes, because if you have "too much" power, you can limit it electronically and have a nice wide flat powerband so that your bike can handle super steep hills with high torque or go flat out 50mph with high rpm, all on a single gear, with a mid drive motor and a heavy duty chain and you are left with a few options for the pedal drive, either a classic wide ratio bicycle chain + derailleur or a more simple generator to do torque sensing and force feedback, and no mechanical link, or no pedal at all and just an electric motorcycle

@Factory400 ideally yes but have you ever seen an engine weight being measured with all it's accessories including ECU wire harness, fuel pump, fuel tank filled with gas, fuel lines, radiator,fan, cooling lines, air box, exhaust, cat etc....
electric wipes the floor of combustion with power density, but gas still wins hands down energy density so overall as long as you need long range/fast charging electric is heavier but electric power density makes it much easier to make muscle/performance versions of road EVs, while maintaining efficiency, weight and reliability constant, at a cheap cost. just slap more motors. this means we are actually going to get properly quick EVs (in the 3-4s) with 500+HP that are also good daily drivers and people can afford like model 3/Y Performance, EV6 GT Ioniq 5 N, Volvo EX30. these are not cheap but still ownership cost is way lower than any AMG/M Power/or even american hellcat/mustang GT
