Diem 20 28mph - Anthracite Glitter (Gloss)

The city bike that doesn't look like one — belt-driven, fully integrated, and quick to 28 mph.

The Orbea Diem is a premium urban e-bike built for the commute you actually look forward to. Shimano EP600 power carries you to Class 3 speeds, and the whole bike is integrated top to bottom — lights, cabling, kickstand, rack mounts, cockpit — so nothing looks bolted on. It's fast, refined, and genuinely low-fuss: a daily driver that happens to look like a design object.

The drivetrain is the quiet star of the show. A Gates CDX carbon belt replaces the chain entirely — no grease, no mess, no rusty links — paired with a Shimano 5-speed internal hub and Di2 electronic shifting. That means clean trousers, near-silent running, gears you can change while stopped at a light, and a system that shrugs off weather and needs almost no maintenance. For a bike you ride every day, it's the setup that keeps on giving.

It rides on a low step-through frame — easy on, easy off, whatever you're wearing — and comes fully commuter-equipped: puncture-resistant reflective Schwalbe Marathon tyres, front and rear integrated lighting with a brake-alert rear, full mudguards, an integrated kickstand, and Orbea's RR-01 rack ready for Mik and Ortlieb QL3.1 panniers up to 20 kg. It's even trailer-compatible.

This particular bike is a genuine Orbea MyO custom build — individually specced in Anthracite Glitter (Gloss), not a standard catalog model. We have one on order, in Size M, arriving soon. Reserve it now and it's yours the moment it lands — no configuring, no long wait.
