First Look: Pinarello DYODO e-Road Bike

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.

2019 Pinarello Dyodo - Electric Road Bike

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.

The Dyodo will be available for shipment in the United States starting now. Have any questions about the 2019 Pinarello Dyodo electric road bike? Feel free to give us a call during business hours, or shoot us an email any time at

Ok...which bike (Orbea vs Pinarello) is the better bike??? Which has the better value....I realize the Orbea is a less expensive bike ..but is it a better value??? How about the geometry difference??? Same power system/ same weight is it just a name thing???also does the Pinarello come with different drivetrains??? SRAM/Shimano.....thanks for taking my question!

That's not a bad idea for some sort of comparison writeup or video between the two! Thanks for the idea!
As for which is the better bike, it really comes down to what you look for out of a bike like this. The Dyodo feels, fits, handles, and performs as close to a Pinarello as you're going to get. The Gain in comparison feels a little more relaxed in comparison (both geometry and handling), but the lower price and clearance for a wider tire make for a compelling and likely higher-selling option.

I’m confused by the 20 mph limiter. What happens when you push 20 miles plus? Does the electric motor shut down? Does it still help you maintain 20 and then you push past 20 with human power? Hope you understand my confusion and can clear things up. Thank you very much

Thanks for the question. The Pinarello Dyodo, as well as a majority of ebikes of this genre, feature a Class 1 drive unit limitation, which limits pedal assist to 20 mph. (More info HERE) After 20 mph, the motor stops offering assist and you have to push past 20 with human power. If you drop below, the assist picks back up to give you a helping hand.

The beauty of a hub motor like that from Ebikemotion is that after the 20 mph assist cutoff, there is no drag, allowing you to keep up the speed if you want to with nothing outside of the additional weight holding you back.

How does it handle on the uphills?

Thanks for reaching out. The Dyodo has similar geometry to the Pinarello Prince, which is as traditionally Italian as road bike geometry gets. Low speed handling (like climbing) is straightforward and predictable. Holler with any other questions, I am happy to assist John!

I just purchased the Dyodo. I’ve been riding (and still do) a Cervelo S3 for a number of years. We live in the foothills of Northern California, and most of my rides entail moderate to significant climbing. I’m a big guy, 6’4” 250 lbs., but have always taken good care of myself swimming running and cycling most of my life. I also have asthma and an aortic heart valve problem. About a year and half ago, I went into heart failure and now “run” off a pacemaker. While I hadn’t been out riding as much since the pacemaker surgery, the recent “lockdowns” related to Coronavirus have got me back out on the road several days per week (nice being retired). I started having occasional issues on longer-steeper climbs with my pacemaker “pacing” in half once I reached a certain HR. In my case, once the HR hits 180, it instantly reduces to 90. It’s a bit of an odd feeling for sure, but probably even more psychologically of an impact. Long story shortened, I thought about an ebike purchase to potentially help me in certain scenarios as described above.

It was a tough decision given the money, and not knowing for sure if the bike it would even have the desired impact with somebody of my size. After my first ride (about 35 miles and about 1,500’ of climbing), I wanted to almost cry from happiness! This bike was everything and more than I could have expected, and I feel like my cycling life has been completely renewed all over again. I typically only use assistance for the longer, steeper grades, and mostly mid-level assistance only. Needing full assistance on grades is rare, but welcome when used! I find the low-level has minimal benefit for somebody my size, especially when coasting at a low speed (it actually slows you more). However, on long level or mild climbs going into the wind, the low level can be a nice relief from time-to-time. Overall, I only use the assistance about 25% of the time or so, but it’s that 25% or so that makes all of the difference in the world between an enjoyable, but hardy workout… and the same ride triggering my pacemaker and leaving me out of breath and exhausted at the end.

Your videos convinced me to purchase this bike, and I can’t thank you enough. I also cannot say enough positive about the level of service I have received from Contender, I only wish my local shop extended a fraction of your level of customer service. While I still ride my Cervelo on longer flatter routes, this bike has been a miracle for me.

Cheers, Jeff

I'm seriously considering the Dyodo e road or gravel .I'm a long time roadie. My second full knee replacement is now 12 weeks old. I ride a Moots and a Cervelo....but after my 1st replacement, I found my muscle endurance had lessened; making long rides out of what used to be,medium rides.My joy of riding also lessened. It's alot of $ to what amts to my 3rd road bike...but, after everything I've read, it might be just what the doctor ordered to get me up and out once I fully heled up.

Thanks for reaching out. These Ebikemotion-equipped bikes are excellent ebikes, particularly for those who love cycling and want a bit of assist. The Dyodo is among the sharpest-feeling eroad bikes I've used and is uniquely a Pinarello.

Is there a reason this Dyodo isn't offered in 61cm? There are riders 6'3" and taller that would like to have an ebike to assist on hills.

Hi Kenneth and thanks for the comment. While we can't speak to why Pinarello doesn't make a size bigger than 58, the 58 is still a fairly large size in comparison to most other brands in that size. The top tube in this size is an effective 59 for the Dyodo. Thanks!
