Giant Road E+ 1 Pro

It uses an integrated drive unit built on Giant's long-running motor partnership with Yamaha, part of Giant's SyncDrive line. The spec sheet pairs it with a battery system that Giant credits for the bike's range claims.

Giant claims a range of up to 80 miles on a charge for mixed-terrain riding. Real-world distance will be shorter depending on assist level, rider weight, and how much climbing is involved.

The Road E+ line is marketed in the U.S. as a Class 3 pedal-assist bike, meaning the motor assists up to 28 mph. Riders should check their local rules, since Class 3 e-bikes face stricter regulations in some states and on some paths.

The catalog spec lists a Shimano Dura-Ace groupset, which is Shimano's top-tier road componentry. That makes it a notably high spec for an assisted road bike, oriented toward efficient pedaling on long mixed-terrain routes.
