The Diem promises class-leading smoothness thanks to its patented Diamond Glide frame <\/p>

Orbea\u2019s new radical-looking urban ebike, the Diem, showcases an all-new frame design incorporating the brand’s patented Diamond Glide frame design.<\/p>

The diamond-shaped rear triangle looks similar to Rondo\u2019s new gravel bike, the Ruut V2<\/a> and Specialized\u2019s Sirrus Carbon<\/a> urban bike. However, this is the first time we\u2019ve seen it on an electric bike<\/a>. <\/p>

Orbea claims its frame design will maintain the stiffness and solidity required for housing a mid-motor <\/a>(Shimano\u2019s EP8 or EP6<\/a>, in this case), while providing “class-leading” bump compliance without the need for a suspension fork or seatpost. <\/p>

Instead, the Diem is all about keeping things as simple and fuss-free as possible, according to Orbea.<\/p>

Where most bikes of this ilk opt for an alloy (or, more rarely, steel) fork, Orbea specs a carbon example to absorb vibrations and reduce weight. The frame is made from hydroformed aluminium<\/a>.<\/p>

The deeply sloped hydroformed top tube is almost flat, and mirrored neatly by the forward-facing top section of the diamond-shaped rear triangle.<\/p>

The Diem\u2019s steering features a \u2018Spin Block\u2019, which prevents the bar from rotating fully. Orbea says this makes the bike more stable when propped on its kickstand.<\/p>

The Diem\u2019s frame shape was designed to keep much of the weight as low as possible, aiding stability, while the front end is relaxed to a 70-degree head angle to keep the steering smooth.<\/p>
