Mid Drive Ebike Motor IZIP Yuba

Electric bicycle (eBike) motor technology has steadily improved since its inception back in 1895 (US Patent 552271 A). The crude 10-volt battery-powered eBike patented by Ogden Bolton, Jr. set the stage for what is now an ever-growing class of bicycles. Multiple companies have emerged as of late and are mass-producing mid-drive electric bike motors that offer varying power, total energy and torque specs. Below are the highlights and differences between the top mid-drive electric bike motors available today.

Commuting or Road

No matter which eBike you choose, keep in mind that no mid-drive motor is the same. Electric bike manufacturers will agree that different mid-drive motors are suitable for different styles of riding. Where a Bosch Performance Line Speed motor offers top speed with a heavier motor for commuting, the Yamaha PWseries motor provides a lighter unit that can be fitted with double chainrings to offer more gear options for trail riding. Knowing the differences between the most popular mid-drive motors on the market will help you make a more intelligent decision when choosing your new eBike.
