Other JUST DROPPED: All-new Slash+ e-MTB

Thanks for the answer. But looking at the weight numbers, adding the Radial tyres which for me are game changers would land at 500 grams from my full EMTB with 600wh battery (Mondraker Crafty) which would not make to much sense.

So thinking this, the LX with a burly coil build is at least 2.2 lbs lighter, already with the new motor without limitations so I'll just wait for it to drop a bit from MSRP .

@Bogdan_CH for what is worth, all the weight measured of the slash plus are totally irrelevant to me.

Yes you can reach 20.5 with very light parts & casing and tons of investment in everything carbon. I understand people try to make it much lighter but then the bike is not really bombproof anymore as it should be ridden.

On my build, from a 9.7, with grip2, vivid air ultimate, DD/DH casing, alloy handlebar (preference), heavy duty DT Swiss Hybrid ones - no insert, I am nearly 22 kg.

Fully agree, this is not a bike you buy to be only "light(er)". For me personally, the bike is as well around the 22kg's mark, and what I love about it is that when I do shuttle days, or bike-park days, I take the battery out and it is almost like a regular bike.

It only helps on the way up. I never need to be the fastest up, I focus on the down. Hope this makes sense ;)
 
From 22 kg if you take the battery out you end up at 19.6 or as close to 20 kg. That's not what a regular enduro bike weights. There are plenty of values relased by Trek, the Slash is around 1.2-1.5 kg heavier than the Fuel LX. Blame it on the high pivot, not sure. But that's a considerable weight.

From a dead 20 kg, if you take the 580 wh battery out the bike would be at around 17.5 kg for a coiled 170/170 enduro bike which is really respectable with a proper enduro build ( the eagle 90 LX spec is full enduro without the Carbon parts) that can still deliver.

The quarter HP have done an awesome comparison of the Slash vs Fuel and while the Slash is a really nice descending bike the LX is not that far behind.
 
On bike park without the battery, as I bomb the trail I do not feel the weight. Still I do agree it would be nice if it has been lighter.
High pivot is a dream to me so I accept a little more weight, I just again hoped it wasn't so noise heavy.

Do Trek sell the 360 Wh battery and the spacer, for those wanting a smaller/lighter battery in their Slash+?

And does said spacer sit closer to the headtube or the motor?

It's not entirely surprising that the extra frame bracing, chain ring and chain guides add some weight, as well as some drag.

I like the idea of a HP on an e-bike, and I have an Antidote on order that I'm starting to wonder if I'll even get, which is why I'm looking at other options.

But I'm left wondering if on an SL e-bike, maybe it would make more sense to buy the Fuel and a Sidekick hub and maybe get the same performance and save a lot of weight, and some drag too?

Thoughts?

Yes, see here. You'll also need the screws (just standard metric hardware). Smaller battery sits lower/closer to the motor.

Weight is such a red herring on eBikes.....

The mid/high pivot has so many advantages beyond just pedal kickback. Straight up, my slash+ climbs better than my beefed-up Fuel EXe did, pretty much everywhere except service roads (where it still has better range). There are several techy climbs I'd clear 50% on my EXe and nearly everytime on my Slash+, due to the suspension. It is like the HPR is squat/bob free without the negatives of "anti-squat". It has more traction, retains the steep seat angle on punchy steep climbs, and the suspension just feels more efficient. Longer chainstays/wheelbase under load means you don't have to move around so much to keep the bike moving forward.

Far as the weight, I mixed mine up quite a bit last season (no battery/360/580/580+RE).
For me a 1-2kg weight difference is just barely noticeable, and heavier does have advantages.
So even for bike park days I'd choose the 360wh.
I don't think the HP alone adds more than 1kg to the bike and I don't think that will be noticable, other than the drag/noise from the upper pulley.

High pivot eBikes have a secret trick: on a high-pivot meat bike, you have the additional drag when back-pedaling or ratcheting your cranks through tech sections. But HP eBikes have the additional freewheel in the motor, so no additional drag when back-pedaling in those scenarios.

As much as I like the ideea of the Slash HPP, for sure it's an amazing bike, but at 22+ kg , it makes it redundant since it overlaps with my current enduro full power bike which is just crazy fun when put in high power modes. For me it was a replacement for a meat powered enduro which doesn't seem that much appealing

They are draggy, the drive train requires an irritating amount of maintenance.

I do love it but it is a pain, do wonder if I should have got a fuel sometimes.

I would 100% disagree with you on an e-bike. The slash+ has no drag unless you ride it without assistance, which is not the point.

That said, make no mistake, the same motor, same geo without HP there would be way less effort from the motor, still you do not feel it much.

The only time I can feel it is: by winter, in mud, with gravity tyres with big nobs if I try to pedal without assistance, bike is dead in the water. Still ... I ride with assistance so cannot feel it.

I also failed to see the required amount of maintenance, it is just untrue. After each ride I clean my bike drive-train and if it is the slash+ or any other HP, it is just one idler to clean too which is basically taking very few time compare to the pulley of a derailleur.

So no to me, the slash+ does not take at all any more time than all my other bikes.

I have an idler equipped bike and have zero issues with maintenance, noise or drag. What level of maintenance do you class as irritating given every bike, idler or not, should really be getting it’s chain at least wiped down and lubed prior to every ride imo.

Id normally drop the chain every 2 or 3 rides during winter and clean thoroughly. With the Slash+ its every ride or two in the winter. I also have to drop the idler and clean it, the bearing needs replacing already since 4 months ownership too.

To be fair to it, during summer months it was far less frequent, and I do use muc off ceramic which is a nuisance. But ive been using it 5 years.

Recently bought an ultrasonic cleaner and going to try out squirt wax.

Again, I love it its an amazing bike
 
Im surprised none of these have popped up second hand yet. Though when you search trek slash + or plus it just brings up normal slashs. Would love ago on one but even with the 60nm update is it outdated now with the current light avinox builds. A druid core e is similar weight with a 800wh battery

Probably being quite a niche bike the owners will have chosen with great care before buying to be sure they got what they really wanted, I know I did. I expect they will be a hard sell on the 2nd hand market exactly for the reason you mention.

I really, really wanted a Druid but didn't want 150mm rear travel as it wasn't sufficient for my personal preference (before any one starts, Ive had 7 years of riding various 150mm-200mm rear bikes and prefer more travel).

Once they released the Druid Core I pulled the trigger on the Slash+. If I could have over-stroked to 160mm I'd of probably bought the Forbidden Lite, although honestly I was really drawn to the TQ system, Ive no requirement for a full power ebike and still have my Levo 3 which I have had since 2021, just cant be arsed to sell it. Its always an effort to ride and I think it genuinely improved my fitness on road, downhill bike and my horrible leg powered enduro these last 5 months of ownership. Theres enough power in the TQ50 to punt you up really some steep climbs but youll work hard for it.

Outdated is the wrong word, simply if you want a full power motor then the TQ isn't going to be for you. I ride it in 100% power some evenings when Im not in the mood and its still hard work at times where the 95nm Levo would just drive you up hills no effort.

Had to clean out and grease my upper idler bearing today - very gritty and a little rusty.

5 months of use. Suprised theres no gasket on them.

Thanks for the insight! i had the fuel exe and never got on with it but i love the idea of the slash at more gnarly places where its a bit much for my many short travel bikes.

Pinkbike reviews have the Core-E at 50.9lbs and the Slash+ at 46lbs. Granted the tires are 1/2lb of that, but still a 4+Lb weight difference and the slash+ has 20mm more travel. I think they are just different bikes and like Mike172, I specifically wanted the lower assist.

A secret trick for the Slash+ is the 360wh battery. Then you're down under 45lbs with DD tires F&R. I found this great for bike park days with an out-of-bounds add-on, or lapping trail networks where I could swap batteries at the bottom. Or weeknight hotlaps. Having both the 360 & 580 is pretty much infinite range. Also being able to hot-swap pre-charged batteries is a huge bonus on camping trips.

Granted the Avinox is loads faster uphill but that's not my priority.

Interesting! Didn’t actually know the smaller battery fitted the slash, that would be great for park days.

You see them crop up every so often, but I would think the second-hand market is somewhat stunted due to what @mike172 said about it being a relatively niche offering and people who bought them really wanting to own one.

You can get a HPR50-equipped 9.7 or 9.9 for excellent money in the sales if you really want one... £4k gets you a 9.7 and £6k a 9.9.

Thanks for the input. I get that some have had other experiences but I don't do much drivetrain maintenance at this time and would prefer to keep it that way.
Also, I tend to think that with an SL motor, every bit of drag matters.
Thx again.
 
If you want to minimize the drag you can remove the lower pulley. I was riding without it for some time and didn’t experience any negative issues with this setup with AXS Transmission. You have to shorten the chain, ofc
Lots of other HP ebikes without a lower pulley as well.
Drivetrain maintenance is not an issue In my experience.

I remember seeing your comments on the Trek Fuel EXe Megathread. I am now considering getting a Slash+. I think my biggest issue with the EXe is not having a preferred mullet setup and the bike feeling too forward leaning. Is there anything you miss riding the EXe compared to the Slash+? Also are you happy with the 50mn motor vs the new 60mn?
