TREK DOMANE+ SLR – PRODUCT LAUNCH

 

Yes, it’s bike launch time again! And you’d be excused for thinking this was simply another new top of the range carbon road bike from market leaders TREK. But look a little closer, notice the + symbol in the product name and you’ll quickly realise that this in fact a brand new e-road bike! The TREK Domane+ SLR is a somewhat revolutionary e-bike that only weighs around 11.8kg and features a drive system that’s so cleverly integrated into the bike it’s almost invisible. The technology that TREK have used to power the bike is compact, superlight and almost completely silent; so what tech have TREK used to produce such a natural looking and feeling e-road bike? Let’s learn a little more about the cutting-edge Domane+ SLR …

The TREK Domane+ SLR is a somewhat revolutionary e-bike that only weighs around 11.8kg

 

It’s easy to miss the fact that the Domane+ SLR is in fact an e-bike because it’s superlight and almost completely silent.

 

Let’s get one thing straight, the all-new TREK Domane+ SLR is crazy light for an e-bike, weighing in at an incredible 11.8kg. That’s thanks in no small part to Trek’s all-new 800-series OCLV frame that is over 700g lighter than the outgoing Domane+ combined with the cutting-edge TQ Harmonic Pin Ring motor which is currently re-writing the rule book when it comes to e-bike motors, thanks to its compact size, light weight and natural feel. Those of you who have been following TREK closely over the past few months will have seen the same motor featuring on their ‘e-mtb-lite’ option – the Fuel EXe launched in July which is Trek’s offering for a rapidly growing market of e-bikes designed to give a much more natural ride feel without unnecessary levels of power and unwanted extra weight.

TREK have utilised the sublime qualities of the TQ motor already seen on their Fuel EXe e-mountain bike.

 

The beautifully integrated TQ drive system is not much larger in diameter than a typical fizzy drink can and takes up very little room in the Domane+ SLR frame; likewise the compact internal battery, located in the downtube, is slim and light so the proportions of the carbon frame look right and there’s sensible weight distribution for a low centre of gravity that doesn’t negatively affect how the bike handles. So how have TQ managed to shrink their motor so significantly? Well most other e-bike motors use gears and belts to transmit power, taking up more space and creating more noise; the TQ Harmonic Pin Ring motor uses a harmonic drive transmission instead which is significantly smaller AND quieter.

The TQ motor is so compact it’s easy to miss it entirely.

 

Here’s some more quick facts on the TQ System…

• Motor: TQ-HPR50 with 50 Nm of torque, up to 300 watts of peak power
• Downtube Internal Battery: TQ360 360Wh
• Battery Range: Approx 80 miles (130 miles with optional Range Extender), 2hr charge time
• Range Extender (sold separately): 160Wh (40% additional range) 900grams, 1hr charge time
• Assist Modes: 3
• Mode-Change Buttons: Mounted to shifters
• Trek Central App: Motor tuning customisation – adjust max power, assist power and pedal response according to assist level. Range estimations, general e-system information

TQ are leading the way when it comes to the move towards lighter, more natural feeling e-bike drive systems.

 

The svelte display is set neatly into the Domane+ SLR’s top tube.

 

Trek’s Central App lets you fine-tune how your Domane+ SLR’s TQ motor assists your pedalling.

 

The TQ motor has been tuned specifically to give a natural-feeling level of pedal assistance which really suits how road bikes are typically ridden; you don’t feel an obvious kick like you do from some other e-bike motors, it’s more of a subtle but equally powerful level of assistance. The TQ motor’s compact size means the Domane+ SLR features a close to standard Q factor (the width of the bottom bracket and chainset combined) while the motor’s control buttons are located on the hoods which all contributes to an authentic real road feel. The Domane+ SLR features all of the same endurance-focused features as the traditional Domane including Trek’s unique IsoSpeed decoupler to smooth out rough roads as well as rider-friendly geometry for all-day comfort. Tyre clearance has been increased too with 40mm now being the maximum compatible tyre width, meaning you’re all set to venture from smooth tarmac to gravel. In summary you benefit from all of the features of the much-loved original Domane with an added natural-feeling boost on the hills or during long rides into rather testing headwinds.

Enjoy a natural-feeling road bike with the added boost required to sail up the hills.
