The problem with e-bikes is that they have been hampered down so hard by regulations.
No throttle, only pedal assist, 250w motors maximum and no assist over 25km/h turns it from the perfect future-proof vehicle for inner-city use and suburban commuting into a weird hybrid that isn't fast enough to replace a light road bike,
But also not strong enough to haul multiple saddlebags full of groceries up hills without breaking a sweat.
I wish someone would make an extension that makes this a simple hover+keypress instead of multiple clicks. As it stands right now it is too much of a hassle to manually click 2 times per video. But if you do not then youtube will continue to plaster that video on your homescreen for weeks.

Hopefully someone writes a better protocol with no third party cookies and heavily restricted javascript.
