Canyon Strive: ON CFR Underdog Review | Bet on the Underdog?
One of the most value-packed enduro’s out there with a killer motor, and high quality frame.
Rarely do I get too caught up in the naming conventions of the e-bikes I test. Most aim to sound EPIC or come with a backstory that’s either cool or sentimental. But calling something an “Underdog” immediately caught my attention. After all, don’t we all like rooting for the underdog? After several weeks of reviewing the Canyon Strive: ON CFR Underdog, I can confidently say it’s a name well-earned. This bike is scrappy and plucky enough to hang with the big boys.
This bike packs plenty of desirable features, like the carbon frame and the renowned Bosch CX motor, but its spec sheet is geared toward a budget-conscious rider. It’s a bike that punches above its weight, holding its own against top-tier enduro rigs without demanding a sky-high price tag. Canyon also offers the LTD version of this bike, loaded with everything you might want, but the Strive: ON Underdog provides everything you need for a fun and aggressive enduro experience.
The Strive: ON CFR Underdog is both stable and responsive. It has a slacked-out headtube, a steep seat tube, and a long wheelbase for getting rowdy even on speedier downhills. Using a 160/170 Fox suspension and Horst linkage, the bike was very controlled on even technical descents.
Of course, the Bosch motor lives up to its stellar reputation. It delivers punchy, responsive engagement, giving just the right amount of assistance when you need it most. The overrun feature adds a helpful boost even after you stop pedaling, making sure finish strong over steep climbs.
The bottom line: this bike can keep up with any enduro eMTB in your friend group. It’s built on a solid foundation that appeals to everyone, from newcomers to seasoned vets, offering a beefy, capable ride without breaking the bank.
- Tremendous value for the money. A carbon frame with excellent geometry, a Bosch motor, Fox suspension, and more. It’s a highly capable enduro eMTB, but as a DTC brand offering, it comes at a lower price than many competitors.
- Powerful Bosch CX motor. It delivers outstanding power, making climbs a breeze so you can hit the downhills feeling fresh and ready.
- Aggressive enduro geometry. It features a slack 63.5° head tube and a steep 78° seat tube, perfect for technical riding and speedy descents.
- Smooth and supportive suspension. 160mm/170mm Fox suspension handles chatter and impacts with ease.
- Mullet wheel setup (29/27.5). Combines the rollover and traction of the 29-inch front wheel with the maneuverability of the 27.5-inch rear wheel, offering a light and agile ride.
- SRAM brakes work well. They provide excellent stopping power and control for confident descents.
- Reliable shifting. Solid and precise gear changes for a smooth ride.
- The battery latch is a bit flimsy and could be improved.
- Not a con, more of a PSA: Sizing runs large. Be sure to check the sizing/geometry chart carefully before purchasing!

Canyon Strive: ON CFR Underdog Review: Motor and Battery
Our test bike came equipped with the renowned Gen 4 Bosch Performance Line CX motor. It’s known for several strengths and only one fairly minor drawback.
First, the positives: it provides 250W of nominal power with a 600W peak. These figures allow it to gather speed quickly, and the 85Nm of torque helps propel you up hills. The system is designed to amplify the rider’s effort by up to 340%, making tough climbs and acceleration feel near effortless when running it at max power.
The motor features a slight “overrun,” providing a brief push after you stop pedaling. This is particularly useful for finishing technical climbs, as it keeps you moving just long enough to clear any final obstacles or keep moving as you lift your front end over the crest of a hill.
The motor has four assist levels: Eco, Tour+, eMTB, and Turbo. eMTB mode is adaptive, syncing with your effort level to deliver a mild boost when you’re cruising and a stronger push when you’re really pressing down on the cranks.
The other three modes serve as low, medium, and high settings. Personally, I used low and medium for most of my riding and switched to high on steep sections or when I wanted extra speed for jumps. The adaptive mode works well enough, I’m just a stickler for control.
The only downside to the motor is the noise. The CX motor has a well-known rattle, especially noticeable on rough downhill sections. I found it faded into the background once I got used to it, but it’s a recognized tradeoff with the Gen 4 motor. Bosch recently released a Gen 5 model, and we’re hopeful this issue has been addressed.
The battery is also by Bosch, making it compatible with the Bosch ecosystem. It’s fairly efficient, as we’ll cover in the range test, and can be expanded. If the 625Wh battery doesn’t provide enough range, you can purchase Bosch’s Powermore range extender for a few hundred dollars, adding an extra 250Wh (40%) of capacity.
As a final bonus, all Bosch systems are fully UL certified, so it’s nice to know it passes all the safety checks too.
Canyon Strive: ON CFR Underdog Review: Display & App
The battery has 5 bars that change colors to signify when an increment is half-spent. This means you can see the battery dwindle 10% at a time, which is good enough for at-a-glance estimates of your remaining battery life. The color that outlines the display ties into which PAS you’re riding in. Green means Eco, blue means Tour+, purple means eMTB, and red means Turbo.
While I’m not personally one for large displays on eMTBs, you do have the option of turning your phone into a display that will give you more of the nitty-gritty details like your speedometer, odometer, percentage remaining on battery life, and more. This is made possible with the Bosch Flow app.
The app also has some nice customization options. I think the majority of people will appreciate the motor’s out-of-the-box settings, but you can tailor the power level, how much torque you get, pedal sensitivity, and more in the app’s tuning features. I played around with it some but found myself setting everything back to standard as that rode really well.
A great benefit of the app is that it can receive OTA updates so Bosch can make improvements to the ride over time. I love connected systems as they help prolong the usefulness of your bike and stave off feeling like your ride is out of date.
Canyon Strive: ON CFR Underdog Review: Range Test
An essential question for any e-bike: How far will it go? We conducted a range test to find out! Now, let me get a large caveat out of the way: we can’t control all the variables that affect range. That list goes a long way, but the chart above was created by controlling as many factors as possible. Our range test is done on the same course, with riders of similar weights and skill levels, and we do the whole thing on the highest PAS level possible to answer the least amount of miles you can expect out of a ride based on a full charge.
The Canyon Strive: ON had one of the best showings we’ve seen all year. It went 25.32 miles until the battery gave out. That’s one of the longer results we’ve seen, which is great from a high-power motor.
Remember, that’s 25 miles when pushing full throttle the whole time. That’s excessive for singletrack, and most riding is done with low to medium power usage or, at the very least, a healthy mix. Your mileage may vary, but it will likely be more miles.
A huge part of the impressive result: the battery size. We’ve tested similar motors with larger batteries that didn’t go that far. Bosch threads the needle of feeling powerful, but not wasting power either.
As I mentioned before, you do have the option to add on Bosch’s range extender, which should add another 40% to the 625Wh option or roughly ten additional miles of riding based on our results.
Canyon Strive: ON CFR Underdog Review: Hill Test
The graph above shows how the Stive: ON CFR Underdog stacks up against fellow eMTBs on hill climbs. As you can see, it more than holds its own against other bike models and different motors.
On our first test on the paved trail it made it up in a minute and 24 seconds. That’s a little better than the average eMTB comparatively. It beat the average by five seconds. At our second hill test location it once again showcased it’s speed, beating the average by eight seconds.
It really doesn’t matter if you have a sharp climb in front of you, or a long drawn out one. The motor does a great job giving you the boost you need, and the 85 Nm of torque helps you climb whatever obstacle is in your way.
Experienced riders will appreciate some of Bosch’s nuance. The slight overrun of the motor where it powers you for less than a second after you stop pedaling really makes it nice for ensuring you get over any hill.
Canyon Strive: ON CFR Underdog Review: Ride Quality
The suspension is stiff and supportive, which makes it great for climbing and stable on descents, though it’s not as plush as some other setups. Our test bike came with an air spacer in the front fork, and we preferred the ride after removing it.
More than anything, we were pleasantly surprised by the bike’s agility. The 38mm stanchions and longer wheelbase make it appear larger than it feels to ride, offering better-than-expected maneuverability.
This serves as a reminder: the bike’s sizing runs large, and for the first time, I think I would have been better off on a medium rather than the large we tested. Be sure to consult the geometry chart to find the best fit for your preferences.
The brakes worked reliably. SRAM’s DB8 4-piston hydraulics have all the stopping power you need to stop in a hurry, and they have operated just fine over all of our testing. Not having a lot to talk about where the brakes are concerned is a plus when I’m reviewing a bike.
The mixed-wheel setup felt like a good choice on this bike. Since it did feel a little large to us, it was nice to have the more agil feel of a 27.5-inch tire in the rear. Overall though, the bike just felt very stable with the larger-than-most wheelbase and nice tire setup.
On a final note, I have a cool story to share. Some people hesitate to buy a direct-to-consumer (DTC) bike because they’re unsure about service options. Canyon, however, handles this well.
Their website provides a network of mechanics with decent service coverage, and many shops familiar with other Bosch motors should be able to work on this one, too—though I’d recommend calling ahead of purchase just to verify that. If you need assistance with other parts, Canyon’s team is very responsive.
Because this is a pass-along media bike, sometimes we encounter surprises that surface during testing. Fun for us, right?
With this bike, we needed a replacement main pivot nut and screw. We reached out to a helpful representative at Canyon named Jake, who went through a “miscellaneous bin” to find the part and sent it to us via FedEx Express—all at no charge and without us mentioning we were e-bike reviewers. That’s great service and a reassuring sign that Canyon cares about its customers.
