TQ HPR 120S

Until not too long ago the TQ HPR 120S was completely unknown to most e-MTBers, despite the fact that it’s been on the market since 2012. With the launch of Haibike’s FLYON series, this has radically changed. Every FLYON model features a TQ motor with only minor modifications.

If we’re talking power the TQ HPR 120S is in a different league. With its 120 Nm torque, it stands well above all other models in our test. As soon as the trail steepens up and the other motors start to struggle, the TQ HPR 120S literally smokes its competition. Shifting down a gear before a steep ramp? That’s soooo 2018! In the two highest support levels, the motor churns out brutal amounts of power, even at low cadences – uphill-flow on a different scale!. The challenge? Stay in control while blasting up the trail at over 20 km/h. The result is a superb ride. Setting off, you’ll want to make sure your front-wheel doesn’t lift off the ground. Inexperienced riders should learn to deal with this much power first. As expected, the extreme power comes at the expense of the range.

Der TQ HPR 120S ist enorm kräftig und zieht problemlos an allen anderen Motoren vorbei.

Even in the medium support-level, the TQ still keeps up with other motors in the highest mode — the motor feels in control setting off and losing traction is rather rare. However, the power delivery doesn’t feel all too natural. When you reach the 25 km/h limit, the motor reduces the support very sensitively – so smoothly in fact that the only thing you’ll notice is the lack of background noise. You won’t feel any pedalling resistance either. At high cadences, TQ’s in-house Pin-Ring gearbox starts humming and the whole unit emits a lot of noise depending on the frame design.

When it comes to integration and tuning options, the people behind TQ give bike manufacturers great freedom and are always open to new individual solutions, the Haibike FLYON being a case in point. Displays, remotes, batteries and speed sensors vary depending on manufacturer, as does the software configuration of the motor.

Conclusion

In terms of power, the TQ’s HPR 120S sets the benchmark and no other motor can match it. But this much power needs somewhere to go – the TQ is sometimes difficult to control and requires a skilled rider.

My technical background has made me the informal workshop manager of E-MOUNTAINBIKE Magazine. Here I prepare the equipment and check the bikes before they’re handed over to our test crew. My nerdy articles and countless explanations are usually the result of me completely dismantling and reassembling a product…
When I ride my eMTB I love shredding on the toughest downhill trails where I push myself and the material to the limit - and beyond. And when I have to get back up to the top of the hill I usually go full "turbo" to stay fresh for the next descend.
