Deruiz neu Quartz 2026
1. Product slogan:
Urban riding. Next level.
The Quartz is one of the most important bikes in Deruiz's history—and a new chapter begins in 2026. After countless kilometers, innumerable user reviews, and the highest ADAC rating among all tested entry-level models in 2024, the Quartz has now been completely redesigned.
The result: a significantly lighter frame, hydraulic disc brakes, a new torque sensor, an optimized design, and a fully app-compatible motor platform.
More control. More comfort. More safety. More Quartz.
Available in Matte Titan Grey, Moonbeam.
2. FEATURES & HIGHLIGHTS:
Simply get on and off.
The entirely newly developed aluminum frame for beginners is lighter, more stable, and has a more harmonious line design. Getting on, starting, and stopping—all feel instantly familiar, intuitive, and agile. The new design reduces the weight by about 3 kg and looks clearer and more modern.
Direct, dynamic, natural: the new torque sensor. The Quartz 2026 rides even smarter. The integrated torque sensor responds precisely to your pedaling strength and delivers a natural, finely tuned support—ideal for stop-and-go, hill starts, or smooth cruising through the city. More control, faster motor response, noticeably more harmonious driving dynamics. Powerful rear-wheel drive—now even more confident. The proven 48-Volt rear motor with 55-Nm torque remains a real powerhouse. Combined with the new sensor system, it accelerates faster, smoother, and more efficiently—whether uphill, with luggage, or over long distances.
Enduringly on the move.
The integrated 644-Wh battery ensures a long range in daily use.
It can be easily removed and charged externally. The new charging port makes the system even safer and compatible with the app configuration of all current Deruiz models.
Safe braking – in any weather.
A major upgrade: the new hydraulic disc brakes with 180-mm discs at both front and rear ensure strong, reliable braking power—whether dry, wet, or downhill.
More control, less effort, significantly more safety.
Fenders in new design.
The new double-layer aluminum fenders from Deruiz are stable, aesthetically pleasing, and free of rubber parts. Minimalist, high-quality, and perfectly matched to the new frame design.
Relyable tires.
Neu: Schwalbe Road Cruiser with K-Guard puncture protection, reflective strips, and a quiet, comfortable rolling behavior. Ideal for urban traffic, gravel roads, and everyday rides – stable, safe, and long-lasting.
Front Baskets & Accessories: More Options
The new exhaust pipe area features four additional mounting points—compatible with all current Deruiz front bays and front carriers. More transport options, seamlessly integrated, stable, and versatile.
More space for everything that matters.
The integrated luggage rack can carry up to 25 kg and is fully compatible with side bags, baskets, and the Quick-Mount system.
Whether it's shopping, a laptop, or weekend gear – everything has its place.
