Rocky Mountain Altitude- Unfiltered 

It's by far the strongest motor of the last 3 years. I'm coming on 2000km on it. I think I learned to use the motor after 1000km. Compared to Bosch putting up 600 watts Powerplay only needs something over 400 to keep up. Or Bosch 800 watts uphill is around 600 on powerplay. It doesn't just give you the power like Bosch you have to know how to use it. The motor isn't really high cadence as it's said to be. It gives you the full power burst when you drop down a gear into a bigger gear. When the motor detects a power spike it gives you more power, so when you drop a gear the pedals slam forward creating a hard power spike. It's pretty problematic way to deliver power as you have to time it right. Before a hill drop a gear, get the acceleration. Obviously you don't want to be dropping gears going into a climb but switching to a smaller gear. So if you don't plan right you might be stuck in the low power state and can't really do anything about it. Where as you touch the pedals on Bosch you have full power instantly. On Powerplay really only way to get the maximum acceleration is that gear drop producing a sharp power spike. Trying to just add power quickly on the feet doesn't produce the same acceleration from the motor. And it's low cadence when you get the most power. Sometimes you just get caught in a low power state in the motor and you are stuck there for the that steep climb. Then usually as you crescent the top and drop a gear then the motor gives you the burst of power. Bosch has had the winning formula of instant power and long overrun for 3 years that's really how it should be done. Powerplay has lazy power delivery and no overrun but the motor is by far the strongest. They basically ruined it with software. Just makes it tricky to use correctly. Where as on Bosch there is nothing to learn you just get the power as you expect it. When you can pedal the Powerplay is the fastest but in technical terrain it's the slowest. On Bosch you can ride between 80-800 watts. But on powerplay you are moreso riding between 200-600 watts. So you need significantly more power to get power from the motor but need less power for climbing. In that sense you can't really rest on the powerplay as you can on Bosch. Altitude is really made for enduro as in pedaling up fireroads and descending. And because the motor software you have to keep spinning the cranks so yeah it's just a horrible combination. This bike was designed by people who don't pedal technical trails and aren't ebike riders. You'd think the Instinct as a trail bike woulda had a higher BB but no it had lower... Cost 500€ to drill 150mm Atlas cranks, new BB, new spider lockring. This bike absolutely needs 150mm cranks. I still prefer the Powerplay as of now because it allows you to go the fastest the easiest. But I no longer really pedal technical trails where you have to crank like on Bosch.

8 NM blue loctite, that's what you were looking for, in the manual find the link to the parts list then you'll be directed to download it on PDF torque specs are written next to the corresponding fasteners, keep it preciously btw the one for my 2019 C70 was already unavailable last year...😅

After reading everyone's post here and seeing your responses I can say this... 1. You most likely needed to calibrate your RM PP. Mine does technical climbs like a beast. No issues with low cadence power delivery. When it's out of calibration it can run like a dog. 2. Many people don't understand that the Powerplay line uses a proprietary cranks because of the imbedded clutch. You can NOT uses normal clinch cranks on these bikes. This is why owners are so disappointed. Rocky Mountain sells these bikes with 170mm cranks on the L/XL and 165mm cranks for the S/M and Race Face does not make aftermarket cranks in smaller sizes. IMHO, I have no idea as to why Race Face isn't making their Ride/Atlas model cranks for these bikes in 160mm, 155mm and 150mm sizes. On that point, I have no idea why Rocky Mountain isn't specing their PP line up with 160mm cranks stock. 3. The Rocky Mountain tech manual is one of the better manuals I've seen and used. 4. The stack height on the RM Altitude PP is 650mm on the XL in Position 2 and 636mm on the L in the same position. The Levo is 642mm on the S5 and 633mm on the S4 size. So the RM PP has an actually taller stack as per their numbers. That said I run the SQLab's 30 X 12° bar with the 45mm rise and love them. Hope this helps.

How has Race Face, and Rocky Mountain for that matter, missed out on the opportunity to sell every RM PP owner an affordable 160/155/150mm crank option? On a side note my RM PP Altitude out climbs all my friend's ebbs, so I'm not sure what's up with yours 🤔

I was seriously looking at the rocky a couple of months ago, two things that turned me off it in the end. 1 was potential motor / electrical problems, 2 was the crank length. not having a local rocky dealer worried me and I was not that keen on buying new crank arms on day zero. I do wish I still got rocky as they do have a reputation to be an amazing descending bike. as you never know if the horror stories are that frequent or 1 in 500

Have you tried a calibration on your bike yet? It’s takes 30seconds trail side and usually gets mine responding quickly again. Mine will start giving assistance with just a little pedal pressure and no crank movement. As for the crank length. You can run any bottom bracket and crank combo like a normal non ebike so it’s not a Rocky Mountain part. You just need cranks that work with raceface cinch chainrings. You are right on 170mm cranks being too long though. I’m running 165mm atlas cranks and a 180mm fox 38. Flip chip in position 2 and it’s a good balance while still keeping it stable on the downhill.

The first area looked like Gateway Greens, what was the other zone(when talking about climbing)? Looked cool. Cheers!

For your stack height, get some 50mm rise bars, way better than under stem spacers. For your peddle strikes get some Chester ( or Fookner) plastic peddles. The plastic peddles take the edge off the rock strikes and they are thin so farther away from the ground.....your platforms look thick, thick is closer to the ground. You can also run some small clipless peddles( eggbeaters) as there is less to hit the ground. good review

No idea what your issue is with the climb. I ride my Powerplay in Pos 3 (2nd lowest) with 165mm cranks and thin OneUp Flat Pedals and 90% of my riding is on blacks or double blacks on natural steep tech. I don't even have it in the 2+ mode. Just ride it like a normal bike. Yes it operates most powerfully in the 80RPM-100RPM mode, but just ride it like a normal bike and don't expect to be able to just soft pedal it like other eBikes who have their excessive overrun as a feature. Stack height is easily adjustable with an external lower headset cup (Wolf Tooth make one). Also why would you complain about stack height (it's in line with say a Stumpy Evo or most all-mountain/Enduro bikes) and run the bike with 10mm of spacers?! There are a bunch of old guys from NZ doing speed tests with this vs. Yahama and Shimano and it smokes them (And none of them are complaining about slow pedalling issues or pedal strikes).

I have no problems with low cadence on mine. sure it gives full power at 80 rpm but mine still produces all the power I need at 60. I haven't tried lower as 60 is about as slow as I can peddal. I have zero vibrations on mine so id get yours checked. I don't get your stack height complaint. I came from a specialized with a lower stack height. It isn't like the altitude is super short in stack. compare it to other bikes and some are shorter in stack and some taller in stack.

Bro, you didn't calibrate the motor and it is obvious" not give assistance at low cadence" is completely telling. Also most of your prdal strikes are not the cranks, it's the super linier coil DHX2, get an air shock 230 62.5 on it. ~yours truely , from a specialized and rocky dealer

You could use hope kids cranks. Remy Morton does, if they are good enough and hold up for him, they will work for you too

Have you tried taking the shock eyelet bearings out of your DHX2 yet? That rocky tool doesn't work my local rocky dealer had to use channel locks and elbow grease. Pretty big oversight if you ask me.

The Dyname 4 motor is working most optimally ABOVE 80 rpm... something is off with yours.

And shouldn't the stroke be 62.5 for the altitude conversion? I have Al altitude and shock stroke is 62.5.

Raceface make a 165mm crank for this bike. My medium came with them. Race Face Ride Cinch 34T | 24mm Spindle | Crank Length: SM - MD = 165mm | LG - XL = 170mm. Best motor on the market, not sure why you aren't getting along with it. I ride Sandy also and don't have the pedal strike issues you do, but do have the 165mm. You might want to check you coil sag, that can also create pedal strikes if you don't have the correct coil.

I'll shoot a theory that you're dead-sailoring due to the rebound of the increased progressiveness you aren't used to coming from the big S bike. I could be wrong, just a thought.

If you're feeling adventerous and want to try some Aliexpress shocks; I have an Altitude (not powerplay) and can confirm the following: - The standard shock mount can take a 240mm shock with a 27.5" rear wheel - The MX shock mount will take a 220mm shock with a 29" rear wheel - The Instinct shock mount will take a 220mm shock with a 27.5" rear wheel Clearance to the seat tube will be slim in some of these configurations, but so far I have not observed any rubbing or other problems. With the DNM RCP-2S 220x66mm I get around 180-185mm travel, and with the 240x76mm I get around 185-205mm travel, probably (I haven't measured the exact travel). The rear wheel does not contact the seat or seat tube on full compression in any of these configurations. I do not know if this carries over to the Powerplay. But you will void your warranty for sure:P To fit DNM shocks on Rocky Mountain bikes, you will need 2 x 0.5mm washers along with 24mm bushings on the top eyelet, and 40mm bushings on the rear eyelet.

I have an analog Instinct and Rocky has always responded quickly w any service questions. Put some 160mm cranks on it. You are big dude on a bike w the weight at the motor/bb. The bb is going to sink dramatically, hence, the pedal strikes. I weigh 175 lbs, so I rarely hit cranks or bottom out on my analog w the 170mm cranks. This ebike demands you be fit to unleash its capabilities. Also, the geo on Rockys is a biased front center, and you are more on top the bars. They counter that w a longish chain stay to keep the bike planted. That is why Rockys corner so well.

reach for xl often 505

Yeah those cranks do not need to be that long
