Pinarello Nytro ebike boasts light weight and performance oriented design

Inspired by the Dogma using the Fazua Evation electric motor

The latest from Pinarello is the Nytro ebike. When the Treviso-based Italian bike manufacture set out to introduce an electric assist bike to their line-up, Pinarello wanted it to boast performance and aesthetics that stayed true to their race oriented offerings. At only 13 kg with a geometry and design that is similar to the range topping Dogma F-10, the Nytro uses a Fazua Evation to assist the rider.

Ebikes give riders more opportunities to go longer, faster and perhaps differently than they otherwise would be able to. While the weight penalty of most ebikes is a constraint in certain situations, at only 4.7 kg the Fazua Evation is light and compact motor so Pinarello could achieve the performance they were seeking with the Nytro.

The Fazua Evation is installed in the downtube to ensure the bike has a low centre of gravity and is positioned so the bikes handling is less effected by the extra weight. The bike can also be ridden without the battery like a normal bike with only one kg of extra weight remaining on the frame in the form of the BB gear box.

The Fazua Evation has four settings. The support is controlled with a remote with three buttons and battery charge bars that sits on the handle bar. The battery takes three to four hours to fully recharge. The motor has a maximum nominal power of 250 W

A white light indicates the motor is providing no assistance. A green light indicates the motor is in breeze mode—it’s most efficient setting—with a range of 50 km and giving the rider 75 per cent assistance up to 125 W. In this setting a rider generating 100 W would get a 75 W assistance for a total of 175 W. A blue light indicates River mode with the bike providing 150 per cent assistance up to 250 W. A riders 100 W would be increased to 250 W. Finally a pink light indicates Rocket mode which is the highest assistance setting giving 240 per cent assistance up to 400 W. A riders 100 W would become 340 W. The max speed with assistance is 25 kph.

The transmission is at the bottom bracket. The motor has torque measurement and cadence sensors so rider input and assistance coincide seamlessly for a natural feeling pedal stroke.

The bike has 12 mm thru axles with a flat mount disc set up with 160 mm rotors for maximum stopping power. The frame uses Toray T700 carbon fibre which is lower grade that what is found on top-end Pinarello’s but the company says it provides the balance of tensile strength and impact resistance to handle the forces created by the motors presence.

The bikes geometry isn’t drastically changed from the Dogma with the same vertical tube and fork angles to maintain a similar handling feel as other Pinarello bikes. To ensure stability the wheelbase of the Nytro is one per cent longer than that of the Gan. The head tube is 10 per cent higher for a less aggressive position. One notable change from other Pinarello frames is that the bike uses a threaded Italian bottom bracket.
