Best Tech of 2017 So Far

Superpedestrian’s robotic bike wheel augments cyclists’ oomph by powering their ride up to 20 miles per hour for over 30 miles. Though it looks like a simple bike wheel, the Copenhagen packs impressive technology inside. An integrated motor powered by a battery provides the giddyup, a wireless sensor connects to smartphones for data crunching, smart-locking hardware makes sure no one makes off with this $1,499 wheel, and regenerative brakes add to the efficiency. Cycling purists might shun the device, but it’s really geared for the increasing number of bike commuters out there. Turns out reinventing the wheel was worth it.
