Who is this motor for?

This motor is for those who want maximum power on a bike. It opens new territory for high-powered riding in a new space between an ebike and a motorcycle. It provides power approaching dirt bikes in an ebike weighing less than 50 pounds - so cool. This is a new sport.

Although it has dirt bike power available, most riders will still want to ride it in a power range where they are still getting good exercise with the nuanced torque-sensing feeling of a high-end eMTB. However, the power is there to deliver the speed when they want to climb steep terrain fast or ride it like a dirt bike. It has one over on popular electric dirt bikes because the Gen 4 Pro uses the bike's gears for high torque on the steepest climbs and when going fast.

It has two modes available. One mode is for being a street-legal ebike. This mode can be any of the three legal classes of ebikes with power and speed restrictions. The second mode can be set up to deliver all the power and speed this motor can deliver - which is considerable. You can switch between these modes on the fly.

Ebike drivetrain. For a great 1x drivetrain, the ebike-rated Box Two, Box Three, and Box Four drivetrains are durable and affordable. With all this motor's power, you will still wear out the higher (smaller) gears on the rear sprocket. Fortunately, Electrify Bike Co. has arranged with Box to sell these as a set of 4 sprockets for just $15, so you can change them out when they slip.
