We already knew Eurobike 2025 was going to be filled with the smallest, lightest electrical bike motors the world has ever seen. What we did not anticipate, although, was for producers to begin outdoing brand-new merchandise they previewed simply weeks in the past. TQ, for instance, debuted what it calls the smallest, lightest, quietest ebike drive in its class in early June. Now, the German e-drive innovator undercuts itself with a good smaller, lighter motor weighing lower than 2.6 lb. It is the all-new HPR40, and it is specifically designed to match the sunshine, lithe strains of highway and gravel bikes.
The massive information behind the HPR60 mid-drive TQ previewed just a few weeks in the past was that it managed an additional 10 Nm of torque with little or no additional mass. With the HPR40, then, TQ takes its newfound packaging effectivity enhancements and applies them to a barely much less highly effective drive so as to reduce weight and dimension to what it calls the “smallest, most effective mid-motor system ever to be present in a bicycle.”
TQ
Grinding nearer and nearer to a good kilogram, TQ brings whole mid-motor weight all the way down to 1,170 g (2.6 lb) whereas detuning output to 200 watts and 40 Nm (29.5 lb-ft). For comparability, the HPR60 weighs in at 1,924 g (4.2 lb) and places out 350 watts together with 60 Nm (44 lb-ft) of torque.
The HPR40 is basically an additional refinement of the HPR50, tuned to higher match the electric-assist wants of highway and gravel bikes. The HPR50 was initially developed in cooperation with Trek for mountain bikes and later tailored to road and gravel bicycles, whereas the HPR40 represents TQ’s first motor drive developed from the bottom up for the lighter, sleeker, extra delicate frames of the highway and gravel markets.

The benefit of shaving down motor dimension is noticeable instantly, because the HPR40 disappears much more dramatically than earlier TQ motors. From some angles, the underside bracket barely even seems to cover a motor in any respect.
TQ enhances the tiny mid-motor with a slim battery pack hid contained in the down tube, a distant management that hides underneath the handlebar tape and a easy energy show built-in neatly in the long run of the handlebar – it is nearly as if the corporate is daring riders to begin a recent spherical of mechanical doping scandals.

As for pedal help, the HPR40 depends on an clever sensor set and adaptive software program package deal to handle help ranges as much as one hundred pc of the rider’s enter, promising a extra pure biking expertise that “rides and appears like a basic highway bike – solely additional, longer, larger.”
One of many first bikes to function the brand new drive system additionally makes its world premiere this week at Eurobike. Among the many lightest electrical highway bikes to ever hit pavement, the Canyon Endurance:ONfly collection limbos slightly below the 10-kg (22-lb) mark to scale weights as little as 9.9 kg (21.8 lb).

Canyon explains that it labored carefully with TQ to develop a drive with probably the most seamless electrical help accessible on a highway bike, a giant departure from electrical drives merely introduced over from the mountain bike market. It then designed the Endurance:ONfly to appear and feel like an ordinary highway bicycle, albeit one which delivers additional pedaling energy when riders want it most. It guarantees near-silent motor efficiency and a clean, non-jarring energy cutoff when the e-drive hits its ruled prime velocity of 25 km/h (15.5 mph), making certain the bike does not develop into dramatically sluggish and sluggish.
The Endurance:ONfly comes with a 290-Wh battery pack built-in into the down tube, which may be augmented with TQ’s 160-Wh water bottle-style vary extender pack. Canyon says that battery duo will energy rides as much as 100 kilometers (62 miles) or extra, full with over 2,000 meters (6,560 ft) of climbing.

The flagship 9.9-kg “Sub 10” mannequin of the Endurance:ONfly collection costs in at €9,999 (approx. US$11,700), whereas lower-tier fashions worth between €4,499 and 6,999 ($5,275 and eight,200) and nonetheless are available in fairly light-weight with a variety between 11.8 and 12 kg (26 and 26.5 lb).
Sadly for US highway cyclists on the lookout for a purposefully honed electrical increase, Canyon says: “In the intervening time, Endurace:ONfly is not going to be accessible inside the USA.”
In the meantime, Ridley is displaying the primary TQHPR40-powered gravel bike with its €8,899 E-ASTR. That one does present as being accessible to order within the US as of July, 22.
