NEW 2027 Orbea DIEM 20 28mph Electric Hybrid Bike - Shimano Nexus Inter-5 Di2

The 2027 Orbea Diem 20 is a premium urban e-bike that makes every A-to-B a pleasure. Built on Orbea's aluminum Diamond Glide frame with a full-carbon fork and powered by a Shimano EP600 motor with an integrated 630Wh battery, it pairs effortless long range with a clean, quiet, low-maintenance belt drive and fully integrated lighting.

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 630Wh 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 3 (28 mph) pedal-assist e-bike, the Diem 20 keeps pace with city traffic.

Clean, Quiet Belt Drive

The Diem 20 runs a Shimano Nexus Inter-5 Di2 electronic 5-speed hub paired with a Gates CDX carbon belt - shifts are at the touch of a button, even at a standstill, and the sealed hub and grease-free belt run clean and silent for years with minimal maintenance.

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.
