The extender gets you closer. But climbing in level 1 is the biggest range extender of all?
TQ HPR60 60Nm - the new TQ gets stronger
- Thread starter knut7
- Start date
Are there even rumours of a TQ50 software update to better manage battery consumption to match the TQ60s?
Hovering over the buy button of a Trek Slash+, I just can't justify £8k with a TQ50 that has poor power consumption when this TQ60 is coming to market. It is my biggest concern with the TQ50. You see the same comments time and time again about power efficiency.

I don’t know about in the UK but in Europe the Slash+ 9.7 can be found on sale for about €6,000-€6,500. Personally I wouldn’t pay full price on a Slash+ now. There’s likely a model with the new motor waiting to drop soon.
It's seems the hpr60 is now available to buy as a standalone motor from the silverfish website in the uk

Anyone going to get one and try retrofitting it into their hpr50 bike?

I get what you are saying - battery consumption isn't the issue with the 580wh battery. Range is great.
The issue is with battery management - thermal self-limiting - restricting power on sustained climbs.
I've been removing my battery cover for service road climbs and it does make a very noticeable difference.
I don't recall the HPR50 on the EXe doing this self-limiting thing nearly as much.

No not the biggest. That is after the battery is gone and your range is unlimited. This happened last night actually. My son used level 1 until it was gone. Good workout.

I may try one to compare. We have three fuel exes. I think the batteries are not compatible, so that would increase the cost. I do not think the cooling fin thing is an issue; the frame cutout size is determined by the motor size. But in reality the 60 does not seem to be available from silverfish or anyone else just yet.It's seems the hpr60 is now available to buy as a standalone motor from the silverfish website in the uk

Dear all
I have Trek fuel Ex-E 9.8 model 2023 and ran about 4500 km, As I read on TQ home page ,it is possible to replace the HPR50 motor with HPR60 by removing the cooling fins and some E-bike makers made adaptors to use the HPR60 motor with cooling fins.Any one has idea that about it?

Not sure any derailleur based system can shift while stationary. Do you mean while coasting?
No, while stationary. It will spin up the motor/chain (but not the pedals) and shift. Pretty sure the Avinox can do it and I thought there were others as well.
That's coast shifting. The bike needs to be moving for that to happen. If a wheel isn't rotating a derailleur won't work. Only gearboxes can change while the bike is stationary.
Yeah I guess I didn't word it correctly, you have to pick the wheel up off the ground but it can be done without peddling. Avinox calls it smoothshift.
Basically what I wa looking for is if I was stopped getting ready to drop in on a line, could I shift the gears without have to ride around in circles before I dropped in. I was more curious then anything, I obviously can do it either way. Just trying to understand the different capabilities of the different motor systems
"
- SmoothShift feature: This feature is specifically designed to allow for shifting while stationary or coasting, making it easier to prepare for a change in terrain."
No body has any idea about replacing HPR50 motor with HPR60 on Trek fuel Ex-E ? I have done for display unit and it is working ok now

The HPR 60 is very impressive from a range POV. Would be interesting to see if they could squeeze some more nm/watts from it, the range figures could still be decent at 70nm/450w I think.

Interesting ...
Using 'turbo' mode should mean that maximum power was used more often, but the HPR 60 was 'only' 2.5 minutes faster (4%) ... so the real world power gain from HPR 50 to 60 is not effective (at least on this loop) and the major benefit is the gain in efficiency.
Strong arguments for putting a 60 into a HPR 50 bike, perhaps leaving only 'cost' as the single barrier ...

The major gain of the Hpr60 over the 50 is efficiency, but you can also notice the torque increase.
When I swapped the hpr50 motor in my fuel exe for the hpr60 motor , my typical range increased by about 15 - 20%.
Nothing else on the bike was changed, same bike, same components, same battery etc.
Could be Mondraker, think they had a HPR50 bike already.
Where were you able to get the motor from and do you mind me asking price?
It was just a simple direct swap / no software issues?
I bought it from silverfish, the UK importer. I think it was £899 (or £800 can't remember), it just bolts straight in, but you need the dealer software to activate it.
It's been fine for 400 miles now.
Only if you cut a hole in the plastic motor cover. But if you remove the fins, the cover fits without modification

Four motors killed with the same error message and by the same person has to point towards something other than the motors themselves being the issue? Nobody is that unlucky.
