DOLOMIT
×
The colors of the Dolomit capture the moment when light glides across the lake – clear, calm, and powerful. A tribute to the mountains reflected in its waters – and to the freedom to climb them.
A lightweight in the heavyweight class.
720 Wh of power. 110 Nm of torque. Yet only 21,6 kilograms (without battery). The Dolomit plays in the top league – light, precise, and strong. Its 6061 aluminum frame has undergone 87 topology optimizations to achieve maximum stiffness at minimum weight. The nearly perfect 49,2-to-50,8 front/rear balance delivers a ride that feels precise, calm, and instinctive – almost like an extension of your body. Whether S/M or L/XL, the Dolomit feels tailor-made for your mountain line.
Power that anticipates.
The 720 Wh battery with 39 Samsung 50-GB cells delivers energy for up to 180 kilometers – even on long and demanding tours. An intelligent Battery Management System protects against overheating and deep discharge, while the Sleep Mode conserves energy when idle.
Fully charged in about five hours, it’s ready for your next climb. Robust, splash-resistant (IPX6), and built for endurance – so you can keep going when others turn back.

Drive & Control
Reads the mountain before you feel it.
The Dolomit reacts before you do. An integrated 50 Hz inclination sensor continuously analyzes terrain changes, while Auto Mode adjusts motor output in just 0,1 seconds. Gyro and torque sensors work together like a digital mountain guide – detecting slopes, gradients, and pedaling intensity to deliver power precisely when you need it. The result: powerful propulsion, natural control, and the feeling of moving in harmony with the mountain.

Safety & Endurance
The Dolomit He remains composed even when things get serious.
Security that grants more freedom.
Components that inspire confidence.
When seconds count, precision is key. The TEKTRO M535 four-piston brakes deliver just that. Dolomit From 25 km/h to a standstill in just 3,8 meters – even in the rain. The SR Suntour XCM fork with 120 mm of travel keeps the front wheel stable, while the Shimano hub ensures precise power transfer. And the Schwalbe Smart Sam 29 x 2.6 tires with a 4,8 mm tread provide reliable grip on any surface. Safety begins at the point of contact – and is evident in every meter you ride.
Everything in sight. Always.
The 1,9-inch display connects via Bluetooth to the Deruiz app and shows the real-time motor output. You’ll have full control of power, range, and assist level – on every trail, in any weather.
Terrain competence & spirit of adventure
Traction you can trust.
Even when the ground gives way, the Dolomit stays composed.<br> The combination of Schwalbe Smart Sam tires, balanced weight distribution, and fine-tuned geometry ensures you hold your line – no matter how demanding the terrain.<br> More grip, less energy loss, maximum control.
Built for height and distance.
Real tours don't end after a battery cycle. That's why the Dolomit Based on a mechanical foundation that delivers consistent performance: the Shimano hub, the TEKTRO four-piston brake, and the 34mm Suntour suspension fork – tested in real-world conditions: on Kitzbühel ice, in the Harz mud, and on Black Forest rocks. After 60 kilometers off-road, you don't want to hope it will hold up. You want to know it will.
