Crestline x DJI - RS 181 SPECTRE Edition

I have both and maybe can shed some light. I live near Bellingham where these bikes were conceived and met both owners.

My Regulator CX is now 160/170 with vivid coil. I upgraded the dropper to 210 from 180. With all these upgrades, this bike is super dialed and on the same level as the crestline suspension feeling.

The Crestline s180 came as stock. The only change was the Axs dropper to 170 and 65mm rise handlebars. Super capable bike and the added battery is nice.

Now that I have a few months with them, I am now leaning towards the Regulator for these reasons:


1. The regulator allows the longer dropper which helps in steep terrain.
2. The lighter weight of the Regulator is nice to have and I get more playful with it.

3. The Regulator gives me the feeling that I am more connected to the bike and feels like more of “cycling”. It just feels more rewarding after the ride than the Crestline for some reason.

4. The Regulator requires me to be more intentional about my route and limit my ride to 2 hours.

I would be happy to own any of them and I am super blessed to get to ride both depending on my mood. If I were to keep one, I’d pick the Regulator.

If you’re near Bellingham, hit me up.

Sincerely, thanks so much for that info.
I'm leaning towards the regulator but am waiting on the CX-R version and my divorce to be finalized. Getting close.
Thanks again though, really.

Sounds like the regulator suits you better. Buy it and ride it like you stole it and report back.

PS Yeah, Crestline vpp is sensational.

Side note. Buying a Crestline and setting it up 160/170 just seems a waste to me.. Its so much fun and so capable in 180mm mode and yet still playful and not boring on the easier trails.

Yet Troyden, who I'm certain has tried all the different configurations, chooses 160/ 170.
There might be a reason for that.
 
The stated bbh for the spectre is 351. Does anyone know if that’s the 181 in the LT position with a 180 fork or is that also for the 161 with a 160 fork? Wondering what the numbers are with st 160 fork.

I have the same question. The thing I'm not certain about with the Spectre is does the short travel setting lower the BB or just shorten then end of suspension travel? I'd prefer 160mm front and back if the HTA stayed the same and dropped the BB.

EDIT: I sent Troydon an email asking geometry 161/160 vs 181/180. Honestly it's pretty common info to have out there. To my mildy educated eye the below makes it look like the end of the rear wheel travel is limited in 161. The axle path wouldn't be the same if 161 lowered the BB bc the axle wouldn't start in the same place. RIght, right?!?!

For those who have setup and ridden your Spectre, anyone not seeing the “Speed Limit“ option under Settings?
 
Yup, 800. Cresty is 54lb and Regulator is 49lb. I can feel the riding weight difference.
So its mainly weight difference and battery choice setting the two apart.

With 600wh my s180 weighs 49.5lb. When slap the 400wh in it drops yo 47.3lb

Im guessing your experience would be different if the s180 spec was differently.

The only reason I can think of is that he doesn't use that bike on big terrain and jumps onto his dh bike at a bike park when going beast mode.

But hey, im a big travel guy hitting big terrain regularly. So that's my bias.

Are you sure there's one coming with the CX-R motor? I work at a shop and just did our booking for 2026 bikes with Transition. No where was there any mention of a version coming out next year with the CX-R motor.

They’re probably working on a DJI bike🤫

I'm not. Really I just presumed they would release one. I figured that they would throw all of the tricks at some obscenely priced version that would include: the CXR, the electric TRP drivetrain that links and autoshifts with the CX-R, the Bosch ABS & the Fox Podium fork. Ugh, it would probably be a $13K e-bike!

So you've already submitted orders, that's interesting.

He rides the PNW and uses his Crestline e-bike, it's about the steepest rideable terrain we've got in the USA I'd say. Apparently, he rides pretty well.

I feel any terrain is rideable with a 160/170. It just might lower your speed at times compared to a proper dual-crown DH bike.

How did you get your 600w version RH2 under 50#s? That's light. What fork and tires? Still have those stupid bars?

We rode in Bellingham and Whistler last year with Troydon and he was definitely on 180/180 there

He actually prefers 170/163 but I think he is going full squish on his DJI if I recall correctly. Mine is also 170/163 and it’s quite capable everywhere. With my new hip and shoulder the DJI will be 180/180 all the way. Can’t wait!

Yep still have the one piece Bontrager bars. Hey they work and dont break when i huck them off 14 foot drops
Enve Fountation wheelset
dhr2 dd wall rear
conti cryptotal enduro wall front
oneup 180 dropper
xt linkglide
xt 4 pot brakes 220/200 rotors
wtb seat - (that standard, i can loose more weight by changing that out
Zeb ultimate 180mm
Suspension tech coil

Since taking this photo
E thirteen one piece 36T chainring
Reverse Blackline pedals
Full set of TI bolts including my own 3d printed motor bolts. Thats an interesting 120 grams saved on bolts...Turns out theres a lot of bolts. I actually have another 4 to change out.

The only light parts you even have are the bar, the dropper I guess & the front tire. I would have guessed 53#s with pedals and the 600w. I love the Linkglide parts but it's a 600+ gram cassette.

+ pedals, ti bolts, alloy chainring, enve's are also about 300 gram lighter than the stock s180 wheelset.
Xt brakes are lighter than stock mavens. No inserts,,,,

Yeah link glide cassette is heavy. I'm keen on trying a Garbaruk cassette next. That's half the weight of link glide.

Also I refuse to compromise performance for weight savings. I could go lighter but then it wouldnt handle the stupid. Right now this bike can handle what ever i throw at it. OK if i went full rocky south island i might change the front tire out to a dd.
 
Finally received my frame 00/99 have it setup 170/161 with a fox podium size rh2 , troyon told me with the works reach adjust headset im using the lower cup keeps geo inline , tomor is first ride.

Does the reach have to be + or - 5 when using that lower cup? I’m looking for a little added stack aswell
 
I’m really looking forward to some nasty hill climbs, one particularly that after many attempts I could not get to the top of with the Bosch Race. I would stall or break traction at the very top. I’m headed right to this climb once my RS181 is built!
Finally got my first ride in this morning before it reached 104 deg!
As I stated earlier 👆🏻, there’s a technical hill climb (down hill for mtb) that I was not able to quite conquer with my previous Bosch Race Crestline. (Around ten previous attempts in 1st and 2nd gear)
My FIRST attempt this morning with the RS181 I nailed it in 3rd gear!!! All the way up without taking a foot off the pedals, in Turbo mode.
Unfortunately my technical hill climb conquer excitement didn’t last long, as most of my ride was listening to a rattling motor box! (With noise canceling Beats with music in my ears) The DJI is no quieter than the Gen4 Bosch. And if you think you’re going to get rid of the rattling with the SideKick hub(on my RS181) or an Ochain, forget get it. Pick up your DJI powered bike and shake it bumping the tires on the ground, you’ll hear the gear lash/rattle. The people that are claiming the DJI is quiet are pavement pounders or riding man made flow tracks. Rocks and rough terrain make this thing rattle just like the Bosch Gen4! So unfortunately I gained no noise improvement with this purchase. Luckily I didn’t trade up from a quiet Bosch Gen5 for this RS181, or I’d be pissed!
The advantage to this purchase is definitely the auto shift! What a game changer for bikes still utilizing the old school derailleur.
The other advantage is this frame looks so much better than the previous Crestlines.
The DJI power delivery is kinda stupid though, you rest your feet on the pedals and away you go! You look like a Mt biker but you’re not really using much leg muscles,…..at least in Turbo mode with the factory settings. This is not what I’m after. I kept it in Trail mode and really enjoyed it, felt similar to Bosch emtb mode and you actually get some leg fitness burn. Downhill jump lines I utilized Turbo mode to gain speed quickly between jumps. I also find the DJI has less resistance when pushing past the 28mph speed limit than the Bosch Gen4, which of course I like.
I was also surprised I finished my ride with only 13% battery and I ran it in Trail 90% of the time. I was expecting 25-30%, and was hopeful to try out a 600wh battery when they become available…..maybe not! I’m going to try Eco and Auto mode more next time.
Overall I guess my Anakin V2 mtb has ruined riding other bikes for me. Wish I could purchase a second one equipped with an integrated QUIET light weight motor and battery. Someone please create a high pivot/high output shaft gearbox no tensioner belt drive emtb that doesn’t rattle and has elec shift. 🙏🏻
If you think the VPP platform is smooth (it is good), try out a high pivot/output shaft with no belt growth or cassette/derailleur weight on the hub…..it’s fantastic!
The RS181 is good, but not good enough to keep me from riding my mtb😍.

Appreciate your critical assessment and welcome more with additional time in the saddle. Folks with the Gen 5 may rest a bit easier now. As an owner of multiple essential bikes, your comments lend weight to this and other topics on this forum.

I feel you about the Anakin. I've been jonesing that bike for some time now. Imagining an ebike version of it, I just don't see Effigear's MGU seeing the light of day, and based on what I've seen it looks like another ungainly MGU entry (I don't even think they were at Eurobike this year, but I could be wrong). And with pedal crank and chainring at the same location (unlike the gearbox version you have), there's no way to get that elevated concentric pivot tensioner-less belt drive suspension of the Anakin. Although this sounds a bit crazy, you could outfit your Anakin with a hub motor, like something from Bafang or Mahle. Actually, I was looking at the Mahle X20 for something like this - 1.39kilos won't weight the rear wheel that much it and doesn't require an internal battery. The bike won't be a shuttle rig, but some SL-like assistance could be welcome.

Is this not the e-bike version of the Anakin?

It is a Cavalerie emtb. But unfortunately does not utilize the Anakin high output shaft, or non tensioner belt 😭 and the motor gearbox is MASIVE! Looks like a dirt bike. I’ll stick with my rattling RS181 for now.

Awesome. Thanks for the mini-review.

Everything else being equal, do you think you'd prefer the Avinox or the updated Gen5, or is it a wash?

Right now (based on reviews as I've never ridden either!) the Avinox has an advantage in terms of absolute power, compactness, battery/ frame aesthetics, auto-shift and ease of increasing max speed.

Where-as the Bosch holds the advantage in terms of bash ring protection, efficiency, traction and natural feeling, noise & local serviceability. The Bosch is getting autoshift and even ABS if that's your jam but maybe on only the CX-R version. The Bosch may also be functionally lighter in terms of how many battery watts one needs to carry to climb a certain amount.

Bosch CX already does autoshift if you outfit your bike with TRP (or 3X3 NINE IGH for that matter, if you are willing to stick with chain instead of belt because of Crestlines VPP/URT rear). The new TRP CMD Switch shifter is sweet.
