In case you spot a snazzy silver ebike at CES this week, you need to know that it is greater than only a fairly face. It is the 3D-printed Titanium Zero, and it sports activities what’s claimed to be the world’s smallest, lightest, highest-torque-density motor.
Constructed as a one-off electrical highway bike idea, the Titanium Zero was designed and constructed by Hong Kong ebike firm Urtopia. Its 3D-printed body is fabricated from a titanium alloy, with the entire bike reportedly tipping the scales at simply 10.8 kg (23.8 lb).
A part of that low weight comes because of a carbon fiber fork, wheel rims/spokes and crankset, together with a titanium seatpost.
That mentioned, the inclusion of Urtopia’s prototype light-weight Quark DM1.2 bottom-bracket motor additionally does not harm. The “1.2” in that title refers to the truth that the motor is claimed to weigh a mere 1.2 kg (2.6 lb).
Boasting options similar to a customized high-precision torque sensor and high-dynamic-response magnetic encoders, the li’l powerplant delivers as much as 65 Nm (48 lb ft) of torque, taking the bike to a high electric-assisted pace of 25 km/h (32 mph).
The motor is powered by a 300-Wh/kg downtube-integrated lithium battery. A Urtopia rep tells us that though the bike has but to be mileage-tested, its estimated battery vary – at high pace and within the lowest gear vary – is roughly 120 km (75 miles).
There are presently no agency plans to place the Titanium Zero into manufacturing, significantly since we’re instructed that the idea’s supplies, technological and labor prices got here out to a complete of about US$50,000. The Quark DM1.2 motor, nevertheless, may fairly seemingly be produced not just for use in Urtopia’s own ebikes, but in addition in these of different producers.
