Reeks of Juicero.

NFS lock and unlock. GPS locator. Capacitance touchscreen controls. Hydraulic disc brakes.

Companion helmet with wirelessly connected brake lights, and noise cancelling(?!) speakers.

Why do we need to learn the same lessons over and over again?

Having hydraulic disc brakes on a bicycle like this isn't something odd. Tons of regular bicycles have them these days.

The only kind of weird thing I see here is the idea the pedals aren't actually directly connected to the drive train, they just turn a generator.

That’s going to separate force-applied from force-required while riding - a much more comfortable pedal action.

That is what gears are for. The only time gears fail is when you want to pedal harder without going faster - charge the battery. Downhill with a tailwind the cautious can reach this situation, but most just go faster.

gears with a chain is more energy efficient.
