Pinarello published the lightest mid-drive E-bike

March 21, 2023

Pinarello has launched a new Nytro line of electric road bikes designed around TQ's HPR50 motor system. Nytro offers both e-road and e-gravel options, as well as an All-Road model with flat bars.

Nytro and Nytro Gravel have different frame designs, and Nytro All-Road uses the same frame as Gravel.

TQ's HPR50 motor and battery is said to be one of the quietest and most compact electric power assist systems on the market, and a growing number of bike brands have developed adaptations for the system, including Trek, Scott, BMC and Simplon. The HPR50 can provide up to 50Nm of torque and up to 300W of auxiliary power.

The lightest mid-range electric road bike on the market

According to Pinarello, the Nytro E9 is the lightest mid-range electric road bike on the market, weighing only 11.4kg with a size of 53cm. In comparison, the Scott Solace eRide 10 weighs closer to 11.8kg, but no specific dimensions. Trek's Domane+ SLR 9 eTap is heavier, with a claimed weight of 12.15kg in size 56.

Both the Nytro and Nytro Gravel E9 and E7 frames are built with Toray T900 carbon fiber, which Pinarello describes as "extreme in terms of stiffness and shock absorption." The E5 series is made of Toray T700 carbon fiber material, which is slightly heavier, but it is said to be equally comfortable.

Xiamen Tour de Cycling Industry&Trade Co.,Ltd. has 150 million square meters plant to supply E BIKE carbon frames OEM service in China.and have 16 years experience to produce all range of carbon frames types.

According to Pinarello, the Nytro's frame weighs just 1130g, but no specific dimensions were mentioned, while the Nytro Gravel is slightly heavier at 1250g. The Nytro fork weighs 440g in the unpainted state, but again without mentioning the size and reserved steerer length, the Nytro Gravel fork weighs 460g.

The headline act is the Nytro E-Road, which comes in three flavours (E9, E7, and E5). All feature electronic Shimano groupsets, cascading from Dura-Ace, through Ultegra, to 105. Only the E7 comes in two colours, with the E5 and E9 in one option only. All can fit 32mm tyres, and wheelsets range from Princeton Grit at the top end, to Fulcrum Racing 800 at the 105 level.

The gravel models, which feature a different geometry and space for 50mm tyres, all feature 1x Sram groupsets. Red for the E9, Force for the E7, and Rival for the E5, with a similar wheel lineup from Princeton through to Fulcrum Rapid Reds. There is also the Nytro Allroad model, which shares the same geometry as the Nytro Gravel but comes with flat bars, mudguards, a pannier rack, and an 11sp Deore drivetrain.

Aerodynamic improvements

Pinarello also made aerodynamic improvements to the Nytro, and says that the headtube, downtube and chainstays have been specifically optimized.

Pinarello even uses a different seatstay design on the Nytro and Gravel models. They said: Nytro's seatstay design is inspired by the F series, while Nytro Gravel's design is inspired by the X series of endurance models.

Of course, the Nytro has an integrated routing design, inheriting the Total Internal Routing (TiCr) system from the Dogma, F-Series and X-Series. It can be seen that the shift wire and brake hose are threaded from the integrated bar, along the steerer tube and passed through the upper headset bearing to achieve full internal routing.

Newly designed seatpost clamp

The Nytro inherits the new saddle clamp design from Pinarello's new F-Series and X-Series. The clamping section is hidden inside the seat tube, and the screw holes are located above the top tube.

Pinarello claims that this reduces the weight by 36g compared to the previous generation, while reducing the profile of this area and improving aerodynamics. The seat post of the Nytro model is the same as that of the F series, and the Nytro Gravel uses a 31.6mm round seat post to facilitate your upgrade to a dropper seat post.

The fork flap design remains

Pinarello continues to use the Onda design philosophy on all the bikes, this wavy fork absorbs vibration and improves handling. The road fork has a 47mm offset and the gravel has a 50mm offset.

In addition, the design of the front fork flap still exists, which hides the front disc brake calipers like a mask, and can also reduce air resistance.
