Orbea Diem 20 E-Bike - Custom Order
Futuristic ground-breaking new urban design. The Orbea Diem 20 EBike is an innovative commuter electric bike which is futuristic in design and light and smooth to ride. Enjoy simplicity and low maintenance with carbon belt drive and Shimano Nexus 5-speed and a range of practical built-in accessories.
Winner 2024 IF Design Award. Patented Diamond Glide Frame. The Diem is a futuristic-looking ebike showcasing Orbea's patented Diamond Glide frame design, winner of an IF Design Award. As well as being striking, the design maintains the stiffness required for an athletic ride performance with vertical flex to absorb vibrations and soften the ride.
Powered by Shimano EP600 with 630Wh high density battery. The Diem 20 has the compact Shimano EP600 motor which is strong (85Nm), lightweight and offers little resistance when pedalling without power. The clean lines are achieved by routing all cabling through the frame and the frame also houses the large 630Wh high-density battery which is claimed to provide up to 9 hours of riding.
Shimano 5-Speed gears with carbon belt drive. Equipped for durability and simplicity and performance with Shimano's Nexus 5-Speed internal hub and Gates belt drive.
Intelligent integration of accessories. The Diem has a range of integrated accessories such as lights built into the head tube and seatpost which automatically switch on as light fades, and a custom kickstand incorporated into the chainstay. The top of the stem has a USB-C port, drawing charge from the battery to power accessories on the go.
Contact us to order or order online. See the Diem 30 for a lighter and more economical option with 9-speed gearing. See the Diem 10 if you prefer Enviolo Automatiq gears.
