Centinel Wheel makes bikes into e-bikes
Like the Copenhagen Wheel and the FlyKly, the Centinel is swapped with a regular bike’s back wheel .
The first model will be a 26-inch wheel size, with other sizes to follow. This entry into the all in the wheel conversion has the novel difference of being powered by two 180w motors, instead of a traditional single motor. The Centinel Wheel is currently the subject of a Kickstarter campaign. Pledges start at US$899, with shipping scheduled for next April if all goes according to plans.by
