At CES this week, Urtopia, a Hong Kong-based ebike company, unveiled the Titanium Zero, a 3D-printed titanium electric road bike concept featuring what is claimed to be the world’s smallest, lightest, and highest-torque-density motor. The Titanium Zero is not only a showcase of innovative engineering but also an impressive display of lightweight construction and high-performance components.
The bike’s frame is crafted from a titanium alloy using 3D printing technology, contributing to its remarkably low weight of just 10.8 kg (23.8 lb). Additional weight savings come from its carbon fiber fork, rims, spokes, and crankset, along with a titanium seatpost.
At the core of the Titanium Zero is Urtopia’s prototype Quark DM1.2 motor, which weighs only 1.2 kg (2.6 lb). Despite its compact size, this motor delivers up to 65 Nm (48 lb ft) of torque, enabling an electric-assisted top speed of 25 km/h (15.5 mph). Urtopia has integrated features like a custom high-precision torque sensor and high-dynamic-response magnetic encoders to ensure responsive and efficient performance.
Powering the motor is a 300-Wh/kg lithium battery, neatly integrated into the bike’s downtube. Although the bike has not yet undergone mileage testing, Urtopia estimates a range of approximately 120 km (75 miles) under optimal conditions, even at top speed and in the lowest gear.
While the Titanium Zero is a concept bike, it comes with a hefty cost—approximately $50,000 due to its materials, technology, and labor requirements. There are no immediate plans for mass production, but Urtopia is exploring the potential of manufacturing the Quark DM1.2 motor for use in its own ebikes and those of other brands.
