Lightweight e-road bikes used to feel like a niche experiment; the Canyon Endurace:ONfly CF 8 makes them look like the future. It takes Canyon’s proven Endurace endurance road platform, slips in TQ’s ultra-compact HPR40 mid-motor and a 290Wh battery, then layers on integrated lights and GPS tracking while still keeping the complete bike right around the 11kg mark. At a glance it could easily pass for a conventional carbon endurance bike – and that is very much the point.
The Endurace:ONfly CF 8 is the high-spec ‘sweet spot’ in the range, sitting below the ultra-light halo model but sharing the same carbon frame, motor and battery system. Full Shimano Ultegra Di2, DT Swiss carbon wheels and Canyon’s flexy VCLS seatpost make it clear this is pitched as a serious performance road bike first and an e-bike second. The assistance is there to smooth out climbs and headwinds, not to turn every ride into a turbo session.

Canyon Endurace:ONfly CF 8 review
The headline with the Endurace:ONfly CF 8 is how little it reminds you of a typical e-road bike. There is no oversized down tube, no swollen bottom bracket area and no hub motor to give the game away. The TQ HPR40 unit sits neatly in the bottom bracket shell, the battery disappears into a slender down tube, and the overall silhouette is very close to a standard Endurace endurance frame. Pick it up and the impression continues; at just over 10kg in a mid-size, it is in the same ballpark as many unassisted carbon endurance bikes with alloy wheels and mechanical shifting.
On the road, that low weight and clean chassis translate into a riding experience that feels reassuringly familiar if you are used to conventional road bikes. The Endurace geometry gives a slightly taller front end and a touch more wheelbase than an outright race bike, which works very well for long days and rougher tarmac. You are not sat bolt upright – this is still a fast road position – but there is enough stack to keep your back and neck happy on multi-hour rides. The VCLS seatpost adds a noticeable bit of controlled flex at the rear, taking the sting out of broken surfaces and coarse chipseal without turning the bike into a pogo stick.
How does the Canyon Endurace:ONfly CF 8 ride?
At typical road speeds, especially once you are above the 25kmh assistance cut-off, the CF 8 feels almost indistinguishable from a non-assisted endurance bike. The DT Swiss carbon wheels spin up quickly and hold speed well, and the 32mm tubeless tyres offer a good balance of rolling speed and comfort. Point it down a fast descent and the longer wheelbase and slightly slacker front end give a calm, planted feel, while the light overall weight makes quick line changes and direction shifts instinctive.
It is when gradients bite or headwinds build that the TQ system quietly earns its keep. Rather than the big shove you get from a full-power 85-90Nm motor, the HPR40 adds more of a strong tailwind sensation. In the lower modes it feels like you on a very good day; in the higher setting, it gently but very noticeably shortens climbs and flattens smaller rises. Because the assistance ramps in and out smoothly and the system is quiet, you do not get that ‘on/off’ sensation or intrusive whine that can break the spell on some e-bikes.
The relatively modest 290Wh battery is well matched to that assistance style. Ridden in efficient modes, it is aimed at big endurance rides rather than short blasts – the kind of day where you might stack multiple climbs and still want power left for the run back home. For riders who want to go further, the 160Wh range extender bottle adds significant extra capacity without compromising weight and handling to the same extent as a bigger internal pack would.
The TQ HPR40 motor and battery system
The TQ HPR40 is a deliberately subtle e-road system, and the Endurace:ONfly CF 8 plays to its strengths. The harmonic pin-ring design keeps the motor small and light, which is a big part of why the complete bike weight is so low, but it also helps keep noise and drag down. Above the legal assist limit, the bike pedals very much like a normal road bike – there is no obvious extra resistance once the motor stops contributing.
Control is handled by a minimal display and a neatly integrated bar-end button, which cycles through three main assistance modes plus off. It is a tidy solution that keeps the cockpit clean, and once you are familiar with the button presses it is easy enough to operate mid-ride. The same system also toggles the integrated lighting, which is powered directly from the main battery. Up front there is a compact light tucked neatly under the bar, while at the back Canyon’s ‘SightStays’ integrate slimline rear lights into the ends of the seatstays. Both are always ready to go, with the system holding back emergency reserves so that the lights will keep running even after the motor has used up its share of the battery.
A particularly neat touch is the built-in GPS tracker. Hidden inside the frame and powered by the main battery (with its own backup cell), it pairs with Canyon’s app to provide live location, motion alerts and theft tracking. For an expensive, highly desirable road bike, that extra layer of digital security feels very welcome, and it is all wrapped into the design rather than being an afterthought zip-tied under the saddle.
What is the Canyon Endurace:ONfly CF 8 like to ride day to day?
Shimano Ultegra Di2 is completely in keeping with the rest of the build. The 2×12 setup gives an exceptionally broad gear range, with smooth steps between ratios, and shifting is as crisp and immediate as you would expect from one of Shimano’s top-tier groupsets. Having electronic shifting and the e-bike system sharing the same battery simplifies charging and keeps cables to a minimum. On rolling terrain in particular, being able to click cleanly between gears while the TQ motor quietly adds or subtracts its contribution makes for a very fluid, enjoyable ride.
Braking is equally confidence-inspiring. Ultegra-level hydraulic discs with 180mm rotors at both ends give strong, controllable power with plenty of heat capacity for long mountain descents. Combined with the stability of the Endurace geometry and the extra reassurance of always-on lights, the CF 8 feels very secure on big days in the hills and on faster, busier roads alike.
Comfort is a definite strong suit. The combination of 32mm tyres (with room to go to 35mm), the flex built into the VCLS seatpost and the slightly more relaxed endurance fit make rougher back roads and patched tarmac much less fatiguing. If your riding leans towards long, steady efforts rather than short, sharp blasts, that blend of comfort and efficiency is likely to be a major draw.
Any negatives?
The trade-offs with the Endurace:ONfly CF 8 are mostly the result of its clear design brief. If you are looking for the outright shove of a full-power e-road or e-gravel bike, the 40Nm HPR40 will not give you the same ‘turbo-boost’ feeling on very steep climbs. It is designed to complement your effort, not replace it. Strong riders will appreciate that nuance; those wanting a more moped-like experience will be better served elsewhere.
Similarly, the 290Wh internal battery – even with the option of a range extender – is not the largest on the market. For most endurance road rides, its efficiency should more than cover typical distances and elevation, but heavier riders regularly tackling very long, mountainous routes in the highest modes may need to think carefully about how they manage support levels.
Tyre clearance is another area where Canyon has stuck to a fairly purist road remit. With room for up to 35mm rubber and proper mudguard mounts, the CF 8 is perfectly capable of four-season road duties and light all-road use, but it is not a gravel bike in disguise. If your idea of ‘endurance’ involves a lot of rough tracks and unmade roads, something with more clearance and slacker geometry will be a better bet.
Finally, the fully internal battery and sleek integration mean that, in practice, most owners will charge the bike as a whole rather than regularly removing the pack. If you already have a stored road bike and can plug in at ground level, that is no hardship; if you live upstairs and are used to carrying just a battery inside, the routine will feel different.
Final thoughts
The Canyon Endurace:ONfly CF 8 is one of the clearest expressions yet of what a modern lightweight e-road bike can be. It looks and rides like a high-end endurance road bike, with the same kind of sharp-yet-composed handling and low weight you would expect at this price, but adds a layer of subtle electric assistance that meaningfully broadens what is possible – longer rides, bigger climbs, more headwinds – without overwhelming the core riding experience.
For riders who love road cycling but want a discreet tailwind in their back pocket, rather than a constantly obvious motor under them, the Endurace:ONfly CF 8 makes a very strong case. It is not trying to muscle into gravel territory or replace a full-power e-MTB; instead, it doubles down on the idea of a fast, comfortable road bike that just happens to help out when you need it most, with the bonus of integrated lights and theft-tracking tech built in from day one.
