Thanks for the feedback on bike carriers - I have just bought a BuzzRack & am impressed.
The main frame arm is adjustable in height, so offers a lot more flexibility in terms of clamping positions.

Has anybody fitted an HPR60 to an EXE and kept the cooling fins on. Most interested in what the hack is to get the motor cover to fit. Asking cos my constantly overheating HPR50 is making some unhappy noises and will inevitably expire at some stage
Yes I did this.
You just need to cut a hole in the plastic motor cover large enough for the fins to fit through. You also need to modify the separate battery cover to shorten the two tabs that locate it into the motor cover.
It's easy to do with a hot Stanley knife blade or hacksaw blade

How does the bike behave with this upgrade?
Do you feel any differences?
And.. do you fear for the exposed fins?
Not sure about how it differs from the updated «eFuel» either regarding BB height and covers?
The exposed fins are removable, so I guess if they get substantially damaged you could just buy a new set and fit them.
Difference wise, the extra 10nm torque is noticable, but the max power is the same as the hpr50 at 300w.
The hpr60 motor is noticeably quieter than the hpr50, and it seems about 15% more efficient.

Thanks for the feedback.
I thought you could choose to run 350 W if you got the cooling fins on, but it seems to be limited to the software we got in our hardware.
This is from the TQ site:
«The new TQ HPR60 is the direct successor to the HPR50 – maintaining the same form factor, but technically upgraded.
- Mechanically compatible, but with additional cooling fins. These can be removed by authorized service partners to fit the motor into HPR50 frames.
- Software is not directly compatible: When operated with HPR50 software, the HPR60 is limited to 300 W, but runs quieter, more efficiently, and with improved torque.
- Many bike brands offer covers and frame adjustments to integrate the HPR60 into existing HPR50-based bikes.»
Maybe you need to flash it as a specific model to be able to?
With the fins mounted it might be just fine with more watts?
Maybe not in extremely hot environments, as the fins look a bit covered?
It believe it would be fun to test those things.

Nice job. Thanks!
You don't get the choice to use 350w max power when the motor is fitted to a bike that originally came with an hpr50 motor. The tq dealer software forces you to have a max of 300wThanks for the feedback.

This might suggest that if you change to the new display and run it as a HPR60 at max capasity?

This depends largely on your riding style and the modes you use.
The built-in battery has a capacity of 360Wh, and the range extender has 160Wh.
In percentage terms, the range extender increases the total capacity by 44.44%.
If you can ride 50km with 360Wh, you could theoretically ride 72.22km with 520Wh.
I ride a lot in the mountains. I'm less concerned about the range there, and more about the elevation gain. But it's precisely here that it becomes very difficult to calculate how much further the range extender will get you. The gradients vary greatly depending on the chosen route and terrain. Whether I ride the gentle incline without assistance or in Eco mode, and then later tackle the steep ramp in boost mode, all of these factors influence how quickly you drain the battery.
Basically, it will get you further.

Are you saying that max power is controlled in the TQ dealer software? So if you know a guy.. it is possible to change it there?
The motor requires that you 'activate' it using the dealer software, if you don't activate it then it doesn't work and just throws an error.
When you activate it you need to enter the serial number of the bike it's going into, the software then does a lookup on a database that tq hold to find out if that bike serial number originally had an hpr50 motor, if it did then it sets the power limit to 300w.
You could in theory input a serial number of a bike that was sold with the hpr60 and get the full 350w, but then there would be two bikes allocated to the same frame serial number, so not sure if that would cause warranty issues further down the line, or software update issues.

Thank you for your insights.
The gains you get with the updated motor seems pretty good even without the 350W though.
What I do wonder about is the difference between fins and no fins.. maybe bigger in warmer climates?

Fuel EXe not recognizing rider input
A friend's low hours EXE will intermittently drop assist level drastically. When this happens we notice that the screen reads 0 for rider input and maybe 20-40 watts for electric assist. So it seems the bike does not recognize the rider is pedaling and so does not add much assist at all. Other times it will perform normally and show similar rider input and motor assist readings as my EXe ridden alongside at the same speed. Turning the system off and on again does not fix the problem, but the bike works normally about half the time, then randomly fails. We need to take it to a dealer for warranty repair but in the meantime I'm wondering if others have had this problem or whether it is a known issue. Thanks for any clues.

Hi
Definitely a known issue especially on earlier bikes, make a video of the the problem while pedalling on the bike, then the dealer can instantly see the problem and address with TQ, I did this with two motors in the early days of my bike and was sorted out no problem.

Read that a lot of people overstroking the rear shock on the Fuel EXe, I recently bought a Fuel EXe 8 XT. Does anybody know if the reservoir of the stock Float X will hit the downtube on a size L alloy frame with the full 65mm stroke?
I will run a 160mm air shaft in the fork and will probably set the mino link to high to avoid contact with the bridge on the seat stays and seat tube during full compression if I overstroke the rear shock

A lot of people have over-stroked their shocks to 65 mm on the EXe. Everything works great. It will increase rear travel to 152 mm. I ran my EXe at 62.5 mm stroke and it gave me 146 mm travel.

Yes, that what I heard just trying to figure out if the reservoir of the Float X will hit the frame before I start to take everything apart. Shocks with transverse reservoir seems to be recommended when going for the full 65mm stroke, like Öhlins, 2026 Float X2 etc
Float X and X2 work. I had run it with both. Also ran it with Marzocchi Bomber air and Rockshox coil

Do you need shorter screws when removing the 2,5mm spacers from the shock?

Hello my dear Fuel rider's
I just got a Trek Fuel EXe 9.8 Gen 1
Can anybody tell me what this third party Integration is within the App? It shows me SRAM Transmission and asks for an Ant+ ID. I am bit puzzled what it for....
Thank you for help

I never used it but Ant+ is the protocol that allows for 3rd party integration. It allows you to see the bikes information on a Garmin for example. Enjoy the bike! I have the same model and have never experienced a more organic feeling eBike motor.

What App are you using? Trek Central?

TQ App didn't know there was a dedicated Trek app

With Trek Central, you can not just do the assistant modes adjustments, read the technical battery status indicators (same as in TQ App), but you get suspension settings and tire air pressure suggestions, along with GPS map navigation showing you how far you can go with the remaining battery. Although it has a strange behaviour for an app supposed to be used in places where Cell coverage is not always available, basically it takes forever to start, and you have to log in to Trek (hopefully), and then you can connect to your bike....TQ App didn't know there was a dedicated Trek app
