Orbea Diem 30 20mph

Shimano Full-Power Assist

The Shimano EP600 drive unit delivers up to 85Nm of torque with smooth, quiet, natural-feeling assistance, flattening hills and keeping you fresh on every commute. The 540Wh battery is built into the downtube for a clean, balanced, theft-resistant package, with an optional 252Wh range extender for even bigger days. As a Class 1 (20 mph) pedal-assist e-bike, the Diem 30 is street-legal on the widest range of paths and bike lanes.

Proven Shimano Gearing

The Diem 30 runs a reliable Shimano CUES U4000 9-speed drivetrain with a wide-range cassette and a tough KMC eGlide chain - simple, durable, and easy to service, with the gear range to handle hills and headwinds.

Designed-In Safety & Comfort

The patented Diamond Glide frame flexes vertically to absorb bumps, while wide Schwalbe Marathon tires smooth out rough streets. Integrated StVZO wraparound lighting keeps you seen day or night, and an integrated kickstand, Spinblock steering limiter, USB-C charging and AirTag-ready mount round out a city bike that's as practical as it is polished.

Available in three colorways

Spaceship Green, Ivory White, and Anthracite Glitter - in sizes S-XL.
