First Impression: Trek Slash + 9.7

So, I finally bit the bullet and bought an e-bike. The Trek Slash+ is a pedal-assist bike, so I won't be whooshing past other cyclists looking like the Wicked Witch of the West. Just the same, I've found it's a surprisingly effective boost to performance.

I own mostly Trek bikes, and I already own two analog Slash bikes (8 and 9), so in term of comparison, I'm able to isolate the difference the motor makes as opposed to dealing with a different bike make and geometry. I also have a standard route through Bert Flinn park in Coquitlam that I ride when I'm going for exercise, so again, easy to tell how much difference the motor makes.

Trek fiddled with the frame sizes a bit when they came out with the Slash+. The L (which is what I have) is a little smaller than the L in a Slash but larger than the M/L. Honestly the only difference I could feel was that the bike felt slightly taller than my 9. It's about 10 lbs heavier, but riding without assist on the flats or slight inclines, I didn't really notice anything. I'm sure I would have on some of the trails if I'd left the boost off, but I'm not a masochist.

The bike rode very much like my regular Slash 9. No surprises, really. It might be a little more stable because of the extra weight, but that's just an impression. I did have a little trouble on tight turns because pedal input would produce more acceleration than I'm used to, so I dabbed a few times. But that's something I'd get used to in a ride or two.

The bike has three levels of boost, selectable from the panel on the top tube. I kept it on level 1 except for one short stretch where I tried out level 3. My quick impression is that you'll rarely if ever need to take it out of 1. I finished my standard course in 1 hr 36 m instead of my usual 1 hr 55 min or so, and I was less tired than usual. So the motor absolutely makes a difference, even with the added weight. And I used 20% in that 1.5 hrs, so I think the battery will probably outlast me on any given day.

Having said that, the whole point of my standard course is to get exercise. I've ridden it so many times that it's become routine, so it's not about conquering the challenge, it's about getting the heart rate up. So I doubt I'll use the Slash+ regularly for this purpose. No, this bike is for venues where you need to pedal up to ride down, like Seymour, Burke Mtn, or Cumberland. In situations like that, you don't want to be using up all your energy grinding up the fire road to get to the trail head. In fact, I'm supposed to be going to the Island in September, and I'll be visiting Cumberland, so this bike will definitely be coming with me.

No one likes getting older, and no one likes finding their stamina slowly evaporating. But I think the Slash+ will extend my years on a bike, and that's a good thing. No regrets.

Yes you will and there's nothing wrong with it unless you're inconsiderate and don't follow trail etiquette. Just be aware you MAY come across emtb haters and all their passive-aggressive comments---in those cases, let them know "it sucks to be them."

Nice bike too. I read good things about it and it's nice to get another user's testimony.

Great bike. Thinking about buying the 9.9 as a few parts of the 9.7 wouldnt hold up. Too bad there is no 9.8 because I wouldnt need the blingbling on the 9.9…

After I quit racing enduro after this season there is really no real need to have one without a motor, as its just a pain to pedal these 18kg bikes to the top, absolutely no fun and I consider myself quiet fit. so its not necessarily a question of getting older or vanishing stamina. At least for me its a question of maximizing the funtimes. This would be my first eBike and it would suit my usecase and terrain in the swiss alps perfectly.

Any more feedback on this bike? Im new to MTB and have been riding my Ripley V4s a ton the last 3.5 months.. Ive gained a ton of fitness and Ive started riding with very experienced riders on some of the more challenging terrain around Marin County.. Problem is Im 65 and have had two back surgeries back in my 30's and 40's. I do great on most uphills and Im really doing well on the downhill gnralier stuff. rock gardens etc.. I like to go fast down hill.

The problems have arisen with my back on the gnarlier uphill sections that really require a lot of max effort along with roots and rocks or other obstacles.. I can do it but sometimes I pay the price the next ten days or so with back pain sciatica, etc which really sucks. So Im thinking maybe I do need an e-bike , but I want minimal assist and the most analog feeling I can get , in a package that will let me rip it downhill and just give that little bit i need on the gnarly uphill sections.

This bike while wildly expensive, seems it will fit the bill to a t. At 65 I dont know how much time ive got to enjoy MTB so I weant to make the most of it while I can.. Im riding 4-5 days a week and Ive been still gaining speed and fitness it seems almost every ride. I really wanted to stay analog but maybe I need a little help for the gnarlier rides. Maybe keep the Ripley too as I really love it !

I've lost almost twenty pounds so far and within a few lbs of high school weight of 165.. Im 6' and the rest of me is in great shape. Not a tone of reviews and feedback on the Slash+ 9.9 as its pretty new.

Anyone here have one and care to enlighten me?

I'm 67. I've also ridden it around Whistler since I posted the thread. I have a regular route through the valley trails as well. For the most part, the ride felt very much like my normal riding, either on the Fuel EX or the regular Slash. Where it made a difference was on a couple of gnarly sections that require more explosive power than I can muster nowadays. With the e-assist, I was able to make it over those sections.

Sure, if I stuck the bike in level 3, I could fly through things, but at level 1 it's just that little bit of boost to get me over the hump.

Small update: I'm riding Bert Flinn again, the biblical rains having finally let up, and definitely enjoying the bike. I find that if I have some more energy because of the assist, I just use it to attack trails more aggressively or do an extra lap. So I'm getting overall the same exercise, but getting more quality riding in.

I do have one annoyance... my Garmin keeps losing and reacquiring the shifter, and every time it does I get a beep. I don't at this point know if it's the Garmin, the way I've mounted it, or the shifter assembly. I'll have to dig out my 9.8 and do a session to figure it out.

Nice! I bought my Gen 6 Slash 1 1/2 years ago. Sadly I've only put maybe 50-60 miles on it. At the time, I felt way too heavy for that bike and couldn't set sag. Now that I'm lighter, I can set sag properly on my Slash. I also swapped my bontrager tires for Maxxis. I kept sliding out on the Bontrager tires.
