Nawa's stylish e-motorbike uses an "ultracapacitor" to drastically boost range

[bob armani]

The 9 kWh battery is a 0.1kWh ultracapacitor that can harvest 80 to 90 percent of the braking energy, much more than lithium-ion batteries alone can store. As such, it can go 300 km (186 miles), compared to 180 km (110 miles) for a bike with the same battery pack alone. Is this something we could see in E-bikes of the future?

This is the first confirmation I have seen on this use. I have been ranting about how someone should incorporate Supercaps into eBike use since I heard of them. Now we just need a savvy DIY like Laserhacker/Lasersaber to whip up a kit. See this:

That would require a regeneration and a direct drive motor. Great for cars, which have a lot of kinetic energy and more headroom for weight. These guys accelerate from stop lights and slow down for the next one. They could use regen in bumper-to-bumper traffic, and if a supercap helps store better, go for it..

I rarely touch the brakes on my bike rides. I enjoy coasting down the few hills we have in Illinois. No need for regen or supercaps here.

That's nothing compared to the flux capacitor.

The only reason it's not widely used yet is because we haven't built a bike that can reach 87 mph.

Yeah was thinking a kit and tire friction device with a lever actuation, possibly tied into the existing brake lever. A universal bolt-on kit might raise some interest and help flatten more hills.
