Trek announced the Domane+ HP, a new addition to their e-road bike range. It uses a Bosch motor and battery, with up to 150 miles of assist when used with the add-on Range Boost battery. There are two levels of spec – plus immediate availability in the Project One custom program.

Trek Domane+ HP long-range e-road bike

It wasn’t long ago that Trek launched the 2020 Domane+ LT. That bike uses the lightweight and compact Fazua e-bike system, and is targeted as a low(ish) weight, stealth e-bike (plus you can entirely remove the system to turn it into a ‘normal’ bike). The new HP version opts for a powerful Bosch motor, a single chainring drivetrain, and a much longer range.

The Bosch Performance Speed model provides assistance up to 28mph, making this a Class 3 e-bike in the US. A full 75NM of torque mean that you’ll feel a substantial boost, similar to the Shimano E-8000 system.

A 500Wh PowerTube battery is integrated into the down tube. It can be charged via a port on the left side of the bike, or removed entirely. An additional 500Wh Range Boost battery is available, though Trek has not released any images or details as of yet. Does it go in a bottle cage like the Specialized Creo Turbo SL? We did stumble upon this page, which suggests that the battery bolts to the back of the downtube, similar to their Allant+ hybrid bikes.

Integrated daytime running lights add a measure of practicality, along with fender and rack mounts.

The Bosch Kiox unit controls power and light systems, along with anti-theft protection.

A Praxis crank with 46t chainring puts your power into motion. Interestingly, the bike opts for a Shimano GRX gravel groupset. Trek did not provide any specific reasoning on this spec, but we have to imagine it’s for chainline reasons, and for a wider potential gearing range than the Ultegra RX derailleurs.

Trek also opts for GRX spec on the brakes, with 160mm rotors front and rear.

Five sizes are available, all using 700c wheels.

Spec & Pricing

Two spec levels are currently offered, with no frameset option at this time.

The Domane+ HP ($7,000, 37.7 lbs) features Shimano GRX mechanical components with an 11-42 cassette. Bontrager Paradigm Comp wheels are paired with Schwalbe G-One Speed 700x35mm tubeless tires.

The Domane+ HP 7 ($9,700, 35.8 lbs) features Shimano GRX Di2 components with an 11-42 cassette. Bontrager Aeolus Pro 3V carbon wheels are paired with Schwalbe G-One Speed 700x35mm tubeless tires.

The Domane+ HP is available immediately from Trek’s website and retail network. It also joins the Domane+ LT with availability in the Project One custom program.

So, it costs more than the Creo, weighs 50% more, and has a smaller battery? Why would I take the 37 lb bike over the 25 lb bike?

I don’t understand what you mean about the battery. It’s got a 500Wh battery by default, but maybe you mean counting the Creo’s range extender batteries? Plus you can add another 500Wh battery to this bike.

Trek did a good job making this look like a regular bike. I’m curious how much weight is shed and how easy it is to “entirely remove the system” and ride in “normal bike” mode. If it’s like 15lbs and takes a minute or something of that order, that seems reasonable. Still, maybe it doesn’t matter that much. Seems like if you’re buying an e-bike like this you’re probably not that interested in its “normal bike” mode, and it’s not like you can remove the system and just leave it on the roadside if you run out of juice.

Removing any of these motor systems is not a quick process and while Bosch makes an excellent system it is not a quick on and off and is not ideal for the cables going in and out all the time. You will likely have to remove the motor and install something that fits the motor mounts.

The battery that Bosch uses is a 500wh powerpack it is not going to be something like Specialized but a standard Bosch battery that is common place on a lot of bikes. Not a bad thing but not something workable for a lightweight travel bike!

The cool thing about the Specialized Creo is you can have your local shop remove the main battery and have a travel battery that can go on a plane! That would be what I want in a bike like this light for travel and some help up hills and mountains.

Bluntly as an owner of Creo SL Xpert:
As a long-distance adventure rider carrying bags, my 26lb Creo is fabulous but harder to climb due to its limited torque power, 35nm. Now, I aim to replace it with a 34lb with a a whopping 75nm!
Bottom line:
It depends on your present personal riding style.
