Sounds like the new Yeti.

Yep, Yeti and Propain will be using it on their new bikes. I was told the updated Trek Fuel Exe will also be using it and I’m sure the Slash+ will eventually get it too.

I looked at the Slash+ but wouldn’t buy one right now, especially knowing the new motor is coming.

I bought one back in March for 30% off. That discount is more than twice the value of a new TQ motor. Maybe I'll upgrade down the road, but the older motor just means I get more range.

I am pretty sold on buying new ebikes that are 1-2yr old motor tech, the discounts are great.

I've owned a Propain Tyee previously and really liked it. Their frame with the HPR60 and 580wh removable battery would be an awesome package.

Here it is :)
 
I think I heard somewhere when they launched the HPR50 that they can get more power out of the same package, and exactly 3 years later they got 15% more power out of the same package... thats hardly any innovation. It looks like exactly the same motor with some fins at the bottom! Quite disappointing especially considering what is happening in the market.
I have been Fuel Exe owner from the beginning, and I am on my 6th motor in 3 years, so hopefully they improved reliability of the HPR60. Can't fault Trek for honouring warranties though :)

that’s crazy! How many km per motor roughly? I was under the impression that the TQ was more reliable :o
 
It is worth swapping on the slash+ just for the improved cooling. I am not in the camp that more power is needed. Looks like it will swap to the Slash+. A bump in power is fine, but it is only 50 watts to 300 constant and 350 surge I presume. The HPR50 is 250 constant and 300 surge. The added torque is more important anyway. As for reliability, both of my bikes have been fine so far.

I can see myself doing it. I don’t use turbo. Could use extra cooling though as I climb a lot

Looks like they are around $1200 but not sure on tariffs. Could be 25% from Germany.

Did you find any available for purchase? Hope someone can clarify if they are actually backwards compatible, guess you will need a new smart box and display. I know there is a "skid plate" on my Fuel Exe that might interfere. But its possible the fins are more towards the back of the motor, also perhaps you can modify the plastic cover.

I called my local Trek dealer and they didn’t know what I was talking about. There was nothing in their system yet. The Slash+ has a bash cover back there as well. Not sure if it fits under it, but I would guess it does. Nothing a Dremel wouldn’t fix if it doesn’t.. I suspect Trek will have a new bash. I think the Slash+ was designed with this motor in mind. My Scott Lumen would fit it no problem, but it doesn’t need it. Guess I will have a spare for it. Maybe a Yeti dealer would know. I’m in no big rush, but it would to stay ahead of demand.
 
Really stoked to see this today. Backwards compatibility is a huge step forward!

As far as mounting to the Slash+, the taco and lower pulley mount directly to the motor- they are the "nuts" the motor bolts thread into. Really great design. So no issues there, and the taco means the cooling fins are protected and won't impede clearance.

The current Slash+ battery & motor covers probably won't work with the HPR60, but those are simple inexpensive parts. Should be easy to modify/DIY if Trek doesn't release updated versions.

I love that TQ has built up a modular battery system. Ability to run 160, 360, 580 or 740 (160+580) is huge. I just got the adapters for my 360 and it's kind of surprising how much lighter the Slash+ seems with that smaller battery.

On my EXe I had taken to hiding a TPU tube under the battery cover. I ran my new Slash+ that for a while and noticed the motor self-limiting. removed the tube and immediatly got 10-20 watts back. Interesting.

Side note, the new Propain Sresh SL looks awesome.
 
May I know which cheapest ebike uses this motor?
I am getting old havent ride my litespeed for years. Perhaps a cheap entry lever ebike with this motor can help me venture again.

Cheap and e-bike are two words that are rarely found together. Your best bet is to buy the last generation model for bigger discounts.

The forthcoming Propain Sresh SL looks intriguing with this drive unit and it will certainly be less money than the Yeti and upcoming Treks.
 
Silverfish in the UK are advertising the new tq hpr 60 drive unit for sale at £899,but they say they won't have stock until early July.

The hpr50 is £799

I've had a look at the images released by TQ on the HPR60 motor internals and noticed a significant change to the Pin Ring drive compared to the HPR50.

TQ HPR60 Internal Changes

It is likely that there are other changes too, but I only have very limited information to go by.

I've updated the CAD model I did for the HPR50 so you can see the changes that have been made to the pin ring drive (might not be 100% accurate but is my best guess based on the images I have seen)

Also if you haven't seen my HPR50 CAD model you can check it out on youtube at Tony W

Thanks for that.

A lot of the reviews of the hpr60 say that it will go much further than the old motor for the same amount of energy, ie it's more efficient.

How do you think they have achieved that improvement in efficiency? Could the physical changes to the motor that you have noticed have caused the increase in efficiency, or is it just due to changes in the software that controls the motor and battery?

I don't really have a good answer to that. I can see that the magnets on the rotor have been changed, probably there are a lot of little things adding up

good job regarding the youtube video. Care to share the cad files???lol.

I think the physical strength and housing of hpr60 is way superior. But somewhere along the way they upgraded all the transmission lines. I think they wanted to be safe than sorry.
Before such a big change, they should try to change the material of parts that 'wears and tears' first. But on the whole, I think its an overwhelming good job.
If you are really into cycloidals, some areas which shd have improvements were left out.

I think it is still 250W nominal/constant. Even the full power bikes have that since it is the law I think.

Thanks for sharing the tech, I am familiar with planetary gear sets, however it is fascinating to see how a cycloidal drive works and how thin the gearbox is.
