Seems like a regular kart, but excessively heavy. Alright, 128HP is a bit more than what you'd expect from something like this.  ____________________ '87 Honda XBR 500, '96 Kawasaki ZX7R P1, '90 Honda CB-1, '88 Kawasaki GPz550, MZ 150 ETZ

It's also bullshit. Uh-huh-huh-huh aside, the motor might be rated to 400A x 250V but they're not using that. Or if they are, it's all going on squealing and raping the rubber.
Electric delivers torque. Power is a different consideration. I don't consider it proven on the basis of that video. ____________________ Biking is 1/20th as dangerous as horse riding.

Yes, they will be the future, but they won't be the present until we have energy storage that's:
High density or very fast charge and with a DC grid and big local energy storage points at 'filling stations'.
and
Light, i.e. not lead based.
and
Cheap, i.e. made of common, easily worked materials.
We can currently manage at most two out of three. That doesn't mean that we're 2/3rds of the way there.
Yamaha's PES-1/PED-1 project seems to have gone a bit quiet, pun intended. ____________________ Biking is 1/20th as dangerous as horse riding.

We are talking a small powerstation working flat out to charge just one bike in the same period. |
Oh, we've done this.

An 85kWh Volt would need 1.7MW and even at 90% efficiency (the current limit for low voltage, low power supercapacitors) would create enough excess heat to raise 100kg of aluminium by 300 degrees.
Bikes batteries are a bit less implausible, but it's going to be a long while (trending to infinity) before we have either a fast charge grid or battery swap stations, so overnight home charging will remain the norm. |
The current generation of electric bikes would be entirely suitable for my ~25 mile commute, but the cost isn't attractive. ____________________ Biking is 1/20th as dangerous as horse riding.

I hear that any sufficiently advanced technology is indistinguishable from magic.
We need a carbon, iron, silicon or aluminium based high-capacity, quick charge battery technology. Cometh the hour, cometh the... wizard.
