The creation of the diode was instrumental in world’s electrification. Diodes allow an electric current to pass in one direction, while blocking it in the opposite direction. They’re in everything electronic that we use, but perhaps the most prominent use of the diode is in LED lighting. Pinarello took that inspiration and ran with it. The all-new Pinarello DYODO e-road bike represents a transfer of energy from the electric drive unit to the rider, allowing riders to go further than they normally would.
We’re no stranger to the Dyodo’s drive unit: the Ebikemotion X35 drive unit, found on the Orbea Gain (review HERE). At the risk of repeating ourselves, we think this is one of the best drive motors on the market today. It’s seriously light, offers assist to 20 mph, 250 W power and 40 Nm torque, and is drag-free when the motor isn’t in use. A 250 Wh battery keeps the power flowing for about 60 miles, depending on how much assist you use. All in, Pinarello claims the entire system weighs in at just 7.7 pounds. An range-extending 250 Wh battery pack will be available at a later date. The complete Dyodo bike weighs only 26.5lbs and offers pedal assistance up to 20mph.
Controlling the motor is the iWoc ONE controller, which controls motor assist levels and displays battery life. The Ebikemotion app here works the same as ever; sync it via bluetooth to your phone or smartwatch, and the app offers real-time battery information, turn-by-turn navigation, auto-uploading to Strava, and more.
IWoc ONE controls the heart of the bike, the Ebikemotion X35 drive motor. This hub-based drive motor is light, offers reliable support up to 20 mph with 250 W power and 40 Nm torque, and is drag-free when the motor isn’t in use. All of this is powered by an internal 250 WH Panasonic battery hidden in the downtube, which combined with the controller and motor, weighs in at under 8 pounds. The whole application is streamlined and intuitive, and rids riders of potential distractions that can take away from an otherwise excellent ride. The Dyodo is over 2 lb lighter than the outgoing Pinarello Nytro, with improved aerodynamics and stiffness, and geometry that more closely aligns with the rest of the Pinarello road bike line.
We’ve found that pedal-assist road bike riders look for the same things that they’d look for out of a standard road bike: smart design, low weight, and a feeling of specialness while riding the bike. Pinarello made sure that the new Dyodo felt like a true Pinarello. Like their Prince Disk road bike, the Dyodo uses Toray T700 carbon, as Pinarello found they can achieve the strength and stiffness they needed without altering size, thickness, or material layup. The main difference in design comes in Pinarello’s asymmetry philosophy; power transmitted through bike can be twice as much as what the standard rider might put through the bike. As such, the drive side chainstay designed with tube cross section 8% wider and tube asymmetry 7% more. (SEE MANUAL FOR A PHOTO)
Perhaps the most appealing part of the Dyodo is, outside of the bigger rear hub and button on the toptube, is that there’s little to distinguish it from a typical Pinarello. Seat tube angle, top tube measurements, and fork measurements, and wheelbase is the same as the Prince Disk. The difference comes in a 10% taller headtube, which ensures the Dyodo maintains the snappy handling of a Pinarello with bit of comfort mixed in. And because much of the weight is found down low (battery and drive unit), the bike feels a bit more stable than your average bike. Think of riding a Pinarello Prince with a six-pack of your favorite beverage around the bottom bracket area, and you’re close to how this feels carving canyons. The drive unit is as seamless as on the Gain, with the pedal assist feeling more like a helping hand than a balance-altering shove.
You’re likely wondering what sets this apart from the Orbea Gain if it has the same drive unit, and ultimately it comes down to the Pinarello brand. Numbers mean little if a bike is missing the incommensurable “ride quality”. If it doesn’t handle well, seasoned riders will still take the lesser option every time over the aero, stiff, and lightweight bike. That’s perhaps where Pinarello makes their mark in the e-road bike world. It takes the power of the Ebikemotion drive unit and melds it with a combination of responsiveness, aerodynamics, and composed handling at the limit. With it comes a promise that you are riding the Pinarello of the e-bike world, because little else truly compares.
Is the Dyodo as revolutionary as it’s namesake, the diode? Not a chance. Is the Dyodo a fun bike? Absolutely. There’s little here to take away from the fun, and as the world becomes less and less analog, the Dyodo promises to combine the best pedal assist technology has to offer with the deeply-rooted emotional pleasure that only a bicycle can offer. Not too shabby.
