Pinarello Nytro E7 Gravel Gravel Bike

Hitting the gravel trails can be a huge enjoyment, but getting stuck on steep climbs or endless false flats won’t be a problem anymore with the Pinarello Nytro E7 Gravel pedal assist e-bike.

Just because you have a motor on your bike doesn’t mean it has to feel clunky and unnatural. The genius behind the Nytro E7 Gravel e-bike is that not only does it look like a non-electric bike – thanks largely to the fact that all road and gravel bikes have huge bottom bracket surface area these days – but also because the TQ-HPR50 motor system feels completely natural and is almost completely silent.

It’s a mid-drive system with a small motor in the bottom bracket region with a design that provides an exceptionally natural feel, not only because it is so quiet, but also because it engages and disengages super rapidly. There’s not the usual lag followed by a kick of power. Simply begin to pedal and the system engages at the level you’ve set it, and as soon as you stop pedaling, the motor will also stop and allow you to coast naturally.

It can feel so natural since the TQ-HPR50 system includes sensors measuring the leg input on each side of the motor. This little innovation must have sounded like music to the Pinarello engineers who have long been committed to asymmetric designs. The TQ-HPR50 motor delivers up to 50 Nm of torque and 300 Watts of peak power. It uses a 360Wh battery and offers a fully integrated 2” display on the top tube. The TQ app allows you to customize what is shown on the display as well as the power output for each of the three levels of power.

The battery life of the TQ-HPR50 system generally depends on how much power you are using, how much climbing you are doing, and even the temperature you are riding in. But you can buy a range extender that can be placed in the seat tube bottle cage and be plugged into the frame using the same port where you’ll recharge the battery.

The tire capacity for the Nytro e-gravel bikes has been blown up to 50mm, which is about as much as you’ll find anywhere. It’s a size that will allow you to tackle even the gnarliest gravel trails. They have also given the Nytro E7 Gravel a round seat tube / seat post design so that you can use any standard dropper seat post. They have also anticipated your trekking wishes and included mounting points for rear racks and mudguards.

For the carbon, they have chosen the Toray T900, which is the same carbon they are using on the Pinarello F7 non-electric road bike. It works well for this application thanks to its high tensile strength, ensuring the frame can withstand both your normal pedal power plus the amplified power provided by the motor. This grade of carbon also offers a great deal of vertical compliance to reduce vibration and rider fatigue on longer outings.

Pinarello turns to their asymmetric way of building up the carbon, giving the drivetrain side a more robust layup to be able to balance out the pedaling forces compared to the non-drivetrain side. Starting with the seatstays and chainstays, the drivetrain and non-drivetrain sides have two different shapes to accommodate the different forces each will experience. Perhaps most complex is the down tube which not only incorporates asymmetry in the design, but also houses the battery, which is completely integrated inside the frame.

The Pinarello Nytro E7 Gravel pedal assist e-bike has been equipped with SRAM Force eTap AXS DB 1x12 and Fulcrum Rapid Red 500 700c wheels. It is an ideal setup for anyone interested in getting off the beaten track fast and far.
