Diem 20 2027

The Orbea Diem is a premium, award-winning city e-bike built to make the daily commute a pleasure rather than a chore. Its patented Diamond Glide alloy frame flexes vertically to smooth out rough streets and, combined with a carbon fork and wider tyres, delivers a genuinely comfortable, composed ride, with the weight kept low and central for confident handling through traffic.

A Shimano EP drive unit gives 85Nm of instant, intuitive power, drawn from a large internal battery (540Wh or 630Wh, plus an optional 252Wh Range Extender) that most riders will charge less than once a week. Choose from three drivetrains – automatic Enviolo with belt drive, Shimano's low-maintenance Inter-5 belt-drive hub, or a 9-speed Shimano CUES chain – alongside fully integrated StVZO lighting, a reactive brake light, dropper post, integrated kickstand, mudguards and rack options up to 30kg.

The Diem 20 offers a refined city build at a more accessible price, with smooth Shimano hub gearing and full commuting kit. It uses Shimano Nexus Inter-5 Di2 e-Bike design gearing and Shimano MT200 Hydraulic Disc brakes, powered by a Shimano EP600 drive unit with an Orbea Internal 630Wh battery.
