Imagine cruising through the city on a bike at 20 mph without exerting much effort? That's what a hybrid bike can do. Any ordinary bike can be turned into a hybrid through the Copenhagen Wheel—a motorized disk unit that attaches to the rear wheel.
The disk module senses the energy of the rider when pedaling and helps provide a boost when biking long distances or going uphill.
There's even a regenerative component to the disk module: Energy is captured when a rider brakes and this energy is stored for later use in the motor.
The Copenhagen Wheel's lithium ion battery has a 30-mile range and can be removed for recharging.
The wheel can be used with the Superpedestrian mobile app to track personal stats like distances traveled, types of topography and calories burned.
Priced at $699, the Copenhagen Wheel doesn't come cheap and it is also not expected to ship to buyers until spring.
Consumers can also choose the electric scooter as an alternative method of transportation provided by the start-up Scoot Networks.
