canyon grail on review 3

“The Canyon Gravel:ON is not for the faint of coronary heart, however its top-tier elements and insane vary are price your consideration.”

  • Construct High quality & Design
  • High quality elements
  • Highly effective Motor
  • Pleasurable on-road or off

Over the previous few years, the gravel neighborhood has solidified a biking tradition that refuses to be burdened with the unwritten guidelines of street biking. This implies bushy legs, fats tires, and an emphasis on having fun with the journey and never how rapidly you’ll be able to end it. E-bikes, whereas rising with a barely much less distinct neighborhood of their very own, are extra extensively accepted than they was once, just because they get extra folks on bikes. Whereas I do know there’s a contingent of Lycra-clad elitists which will take situation with each of these statements, e-bikes and gravel bikes are right here to remain. I welcome the corporate. 

So, it is smart that Canyon launched the Grail:ON, its first entry into the U.S. e-bike market. For those who’re not accustomed to Canyon, you need to be. It makes superb bikes which can be typically the most effective high-end bang on your buck as a result of the corporate operates by way of a direct-to-consumer mannequin. This implies you received’t see new Canyons at your native bike store, however don’t fear. An unbelievable six-year guarantee, 30-day return coverage, and a easy setup with all of the instruments included make for a easy shopping for expertise.

The Grail:ON: What’s it, and what’s totally different?

Born from Canyon’s long-standing gravel favourite, the Grail, the Grail:ON makes extra adjustments than simply slapping a motor and battery on and calling it good. And whereas a motorcycle’s geometry actually isn’t the sexiest subject to get into, with the Grail:ON, it’s price mentioning. Canyon took into consideration what throwing a bunch of additional weight and energy onto a motorcycle would do, they usually modified it accordingly.

This implies they thickened the sidewalls of this all-carbon body to take care of the additional abuse whereas additionally lengthening the wheelbase and shortening the stem. These adjustments translate into an e-bike that’s way more nimble than others I’ve ridden. Actually, the sleek and responsive journey had me forgetting at instances that I used to be using an e-bike in any respect. 


Outdoors of the body and motor, essentially the most vital visible distinction from different bikes is the Grail:ONs double-decker handlebar. This multilevel drop bar appears half hammerhead shark and half medieval weaponry. Whereas it would look insane, the end result is a rise in consolation that you’ll quickly study to like.

For the Grail:ON, the built-in stem has been shortened, which brings that floating high bar nearer to the rider. Which means a extra relaxed and comfy using place. Pulling double obligation, the highest bar additionally helps dampen street vibration when issues get bumpy. I can attest that I used to be fairly skeptical of those claims, however discovered myself spending an increasing number of time on high as a result of it took the sting off tough again roads. 

Fats tires? No downside

Additionally serving to take the sting off bumpy roads are the Grail:ONs tires. Up from 40mm on the Grail to 50mm for the Grail:ON, the Schwalbe G-One Bites are ginormous. After I pulled the Grail:ON from its field, my first thought was that this stuff had been method too massive. With a tread sample simply shy of what I’d contemplate for a mountain bike, the G-One Bites are massive, aggressive, and in a position to journey at solely 30 psi. This implies a great deal of traction and further suspension to absorb bumps, in addition to extra rolling resistance.

If all you’ll be using is unfastened gravel, this isn’t a difficulty, however if you happen to’re like me and journey 80% paved roads with little bits of gravel combined in, rolling resistance turns into extra of a priority. A lot to my shock, for my first outing, I pumped the entrance and rear as much as 55 psi and was shocked when I discovered myself cruising at 21 mph. Seeing as the ability for the Grail:ON stops at 20 mph, the tires and further weight had been balancing themselves fairly properly.


The place I did discover the Grail:ON’s weight, which is claimed at simply over 35 kilos for a medium, was on gravel descents. Whereas I may nonetheless throw the Grail:ON round, I used to be undoubtedly using the 160mm hydraulic disc brakes a bit more durable than regular, and that is the place the additional dimension on the tires actually got here into play. The identical tires that I scoffed at in my lounge had been coming into their very own out in the actual world — I used to be thrilled to have the additional rubber to work with. 

Battery and motor

The perpetrator behind the Grail:ONs weight is, after all, the Bosch Efficiency Line CX motor and detachable 500 watt-hour battery. Canyon selected the Bosch unit as a result of it will possibly throw down as much as 85Nm of torque, which is just below 63 pound-feet or about what an 800cc bike has.

In contrast to motorcycles, the Grail:ON has no throttle — it’s a pedelec, or pedal-assist. Which means that once you begin pedaling, the motor kicks in and provides you help primarily based in your cadence, drive exerted, and total velocity. The ability from the motor is available in 4 varieties. Eco Mode is the least highly effective, adopted by Tour, Sport, and the undisputed king of hill-smashing, Turbo.


All modes are restricted to twenty mph within the U.S. and are chosen by way of the straightforward but efficient Bosch display screen that provides you information in your present velocity, vary, energy mode, and battery life. You’ll be able to, after all, pedal over that 20 mph restrict by yourself energy, in addition to flip off help if you wish to give your self a bit of further exercise.

I haven’t been a giant fan of Bosch motors prior to now, as I discovered them jerky and noisier than I’d count on. The unit within the Grail:ON has modified my thoughts. Its easy supply by no means caught me off guard, whereas on the identical time impressing me with the sheer energy obtainable. My solely gripe with the Bosch system is the show. It exhibits all the things it must regarding the motor, however I’m undoubtedly trying ahead to the day once I don’t should even have my devoted bike pc on board for GPS and monitoring my exercises. 


With regards to vary for the Grail:ON, Canyon estimates {that a} 210-pound rider will get just below 70 miles of vary. E-bike vary is troublesome to quantify resulting from all of the variables in play, however I used to be stunned to see that I blew their estimate out of the water, getting nearer to 110 miles in Eco Mode. Granted, I’m 170 kilos, using totally on paved nation roads with a mixture of hilly and flat terrain. However having a battery that lasts so long as this one makes the eight-hour recharge time a bit of extra bearable.

A phenomenal journey

Additionally serving to with the recharge downtime is how good the Grail:ON appears simply sitting there. It screams, “I’m totally different!” far more than it does “I’m an e-bike!” and that is actually appreciated. Whether or not it’s the super-clean inner cable routing or that Starship Enterprise entrance finish, the Grail:ON is a looker and garners greater than its justifiable share of second glances and inquiries. But it surely’s actually the mixture of standout components and items that carry the entire bundle collectively. 

I’ve talked concerning the tires a lot, however the DT Swiss wheels are additionally price mentioning. With hubs which can be bolstered to take the additional torque from the motor, the HGRC 1400 wheelset provides aerodynamics and power to your journey. The truth that any aerodynamic positive factors are most likely negated by these monster truck tires is irrelevant. They give the impression of being superior! 


The seat publish is one other Canyon specialty that’s price mentioning. Its leaf spring design helps easy the journey out much more than the body already does. Add within the Fizik Argo Tempo saddle, and you’ve got a veritable two-wheel throne utilizing among the smartest design expertise obtainable to the biking neighborhood right this moment.

Talking of expertise, I used the high quality Sram eTap model of the Grail:ON. This implies wi-fi shifting for the 12-speed 10-36 cassette being pushed by a 44 tooth FSA chainring up entrance. Whereas the eTap drivetrain labored flawlessly, there’s one odd factor about it — it makes use of batteries. The wi-fi derailleur makes use of its personal battery, so it isn’t linked to the bike as a complete.

Which means that theoretically, I may run out of batteries on the derailleur and never have the ability to shift, whereas nonetheless having a full cost on the motor. The Sram batteries final two to a few weeks, so so long as you’re charging them together with bike lights and head items, you need to be nice. However I ponder if this technique would have been higher served with a Shimano Di2 setup that also has a hardwire connection and will have been built-in with the bike battery.

Guarantee data

The bike has a six-year guarantee on all Canyon components and elements, with a two-year guarantee on all e-bike components, together with the Bosch motor and battery.

Our take

The Grail:ON is a high of the road gravel bike that occurs to have an e-bike motor. Giving riders a number of energy modes whereas utilizing class-leading elements married to a body that has been expertly tweaked to fulfill the best calls for, the Grail:ON is all the things I’d count on from a world-class builder like Canyon. And with the Grail:ON successful a 2020 Purple Dot award for bicycle design, I’m clearly not the one one who thinks so.  

Is there a greater various?

The closest competitor is the Specialized Turbo Creo SL Comp Carbon at $6,750. However with the Specialised, you miss out on the digital shifting, upgraded wheels and tires, and purchase a a lot much less dramatic aesthetic. If these issues don’t tickle your fancy, perhaps contemplate the Giant Revolt for $4,200 as a extra reasonably priced possibility.

How lengthy will it final?

The sturdiness of the Grail:ON undoubtedly depends upon your use. Whereas carbon fiber isn’t identified for being essentially the most sturdy materials on the planet, the built-up thickness that the Grail:ON employs ought to maintain points at bay. In the meantime, Bosch is understood for making robust as nails electrical motors with batteries formally rated to deal with 500 recharge cycles providing you with years of use earlier than you’ll have to exchange it. Firmware updates will likely be supplied yearly from Bosch sellers to maintain riders updated with the newest gravel software program enhancements. 

Do you have to purchase it?

Sure. If the $6,999 price ticket on the eTap mannequin is a bit an excessive amount of, it’s best to undoubtedly take a look at the usual Grail:ON CF8 mannequin. The CF8 has mechanical shifting and barely cheaper DT Swiss wheels, however in any other case has the identical advantages of massive tires and body design for $5,799.
