The Orbea Gain D50 is a lightweight e-road bike with an aluminum frame, the Mahle/Ebikemotion X35+ rear hub motor (250 W), and an integrated 248 Wh battery. It rides very naturally because the motor provides subtle assistance and the bike remains relatively light at approx. 13.5 kg. It is equipped with a Shimano Claris 2x8 groupset, mechanical disc brakes, and 30 mm Hutchinson tires – ideal for relaxed, sporty tours between 70–100 km depending on the assistance level.
