Crestline x DJI - RS 181 SPECTRE Edition

Where can I find the freehub pre-engagement setting in the Avinox app?
In Advanced Settings. In the main menu about 2/3 of the way down. It certainly does as advertsied. As soon as you put a little pressure on the pedals it spins the chainring enough to engage the rear then stops. Took all of the deadband out of my sidekick.

My e13 makes occasional clunk/engagement sounds. So turn this pre engagement feature on or off?
 
Rob is going crazy with the rattle, the cover for the motors are breaking, internally some are trying to find fixes for cable chatter, others are making exterior cable management changes, and others feel the 600 batter will be better for weight distribution .... This is quite common with first production items in just about everything. Just like with her cars, they say, never buy the first year as the fixes needed to get fixed. That's why I said, awesome bike, fixes needed.
Yep. First adopters perform the r&d whether they like it or not.

Im amused that they whine and complain. When you sign up for something brand new first revision you should be prepared for some niggles.

The bash guard is on though. My s-180 bash is solid. No problems here. Maybe the cooling fin slots of the dji weaken the design.

The feature will engage the paw-pusher just like you would if you were pedaling. So a clunk would remain either way.

As for the feature I'd recommend giving it a try in the parking lot first. If you don't like the deadband it'll certainly get rid of it. I never really noticed the 9 degrees on my ochian, I do notice the 18 on the sidekick so I'm going to try it next ride. SOOO much cool tech, I'm trying one thing at a time to really gauge its effectiveness.
 
This is an awesome bike with some fixes that will take place in gen #2. Like a new car model, they say never buy the first year as fixes will take place. Not saying the bike cover won't get fixed and the annoying rattle won't be fixed, but expect some dust with gen #1.

The Spectre is a dope bike and so good looking but has a few hiccups as all bikes do. And the Avinox might be the largest one actually. I mean it looks WAY better than the Gen5 but efficiency, chain ring protection, weight distribution, power delivery, & noise...these are all real issues.

Frankly I think a Bosch with a non-existent slender 700-800 watt battery would be a better system. Actually, just keep the standard 600w and make a modern Powermore/ RE that uses updated technology.
 
it's not in the app on your phone, it's on the bike screen itself, in advanced settings :)
I don’t like this setting at all. I was riding a trail I’m not that familiar with that had a few small smaller drops (3 or 4 foot drops) so I was hitting them at a slower speed so I can see some of the landing before committing.

When I lift the front wheel a little for the drop (so front wheel is in the air), it compresses the rear suspension a little and I felt the motor kick in and surge me forward. I felt this on 2 out of about 8-9 drops on the trail. It’s not a good sensation.
 
Pre-engagement responds to crank input, not the rear wheel compressing. I never found it supplied any torque, just enough rotation to engage the hub then it stops, likely once it detects feedback from the hub. If anything I wish it spun up a little quicker. I thought it lagged a little creating inconsistent deadband and unpredictable engagement. Could be another setting?

This bike has pedal kickback. When the rear wheel compresses, the pedals rotate say 15 degrees backwards however I like my feet leveled which engages the motor in this setting. Not fun having the motor kick in and propelling you forward during a drop. Mabe I need to try this again to confirm again. It could also be one of the sensitivity settings

You caught me mid edit... sounds like could be too fast pedal engagement? Or it's doing what it's supposed to and engaging the hub faster but like I pointed out a little inconsistently. I'll give it a closer look today myself and confirm what I'm thinking.
 
I’m currently testing out the Onyx hub with instant engagement and i turned down the pedal start assist to try to reduce the motor rattle. So far i think its helped but not completely eliminate it.

I dont think the hub pre-engagement setting ON would do any difference for me sine onyx hubs are already instant engagement. I had the sidekick hub on the bike at first and dont have the loud clunk anymore with the onyx hub

Your implication is that the clunk was coming from the motor taking up the slack in the Sidekick hub? As in the noise, was in the hub, not the motor?

Dumonde Tech Pro helped quiet down the Sidekick engagement for me, but it's still there. The one advantage of the ochain is a very soft elastomer engagement but I'm sold on any kickback device, even with the clunk.
 
Went for a quick ride on a flow trail with some chunk and the pre engagement set to On didn’t affect compressions like I mentioned earlier. It must have been a sensitivity setting that caused the motor to jerk me forward on a drop.

Preengagement reduced the occasional E13 clunk. Didn’t eliminate it but greatly reduced it

Based on the speed pre-engagement rotates the chainring I think your pedal stroke can outpace it and cancel out its effects. I'm going to pay closer attention to it today. Otherwise it's a very smart feature, might need refinement but that's why it's a test feature.

What's everyones thoughts on "Chain Protection"? I like what it's supposed to accomplish. I only notice it under high torque but it's an odd feeling having power drop when you need it most, but it comes right back. I've only broken chains when I stupidly pedal from a stop in a high assist mode/low gear, never during "normal" operation but with the much higher torque of the Avinox it might save a few chains/cassettes.
 
I notice chain protection most in Turbo mode. Felt like it just switch to eco for a half second.

It’s interesting you’ve snapped chain while in a hard gear. Usually that doesn’t happen unless you’ve compromised you chain by smacking your chainring into something (thus the importance of a bash guard that protects the chainring)

The dip in power is most noticeable based on the amount of torque being applied, it doesn't seem to matter what assists mode you're in.
 
Some of the damage was from loose rocks/shale flicking upwards and removing chunks of material off the BB. The loose shale I ride over sounds like I’m riding over broken glass at times.

I’ve never smashed into anything hard. Just climbing up and over steep rocks at very slow crawling speeds and occasionally grazing something.

My 3 other Ebikes (1 I’ve replaced with the Spectre) I’ve ridden hundreds of times in this same terrain with even lower BB’s (338mm on an 170mm Timp Peak mullet setup) only have scratches and gouges. I haven’t had to replace a single BB cover yet. Their BB’s don’t chip away, they bend and deform instead of cracking and chipping.
Since your damage is more caused from debris being flung at it, I wonder if you could coat your new replacement bash guard with something like PlastiDip? To give the exterior a more rubbery surface for debris to bounce off. The obvious downside to this is a rubbery surface would get hung up when it made contact with an item that won’t move like a big rock or tree crossing…..which is what I encounter a lot.
I’d really like a bash guard stamped out of thin stainless sheet metal. When it gets dented, take it off, hammer the dent out and reinstall. The stainless would also slide well over pretty much any surface.
 
The bash guard material couldn't be worse for the application. Seems like an easy fix, just mold it out of another material.

On my YT Decoy I ran one of these, probably the best way for the most protection.

Aluminum is no good for me. It would gouge into the jagged lava rock that I encountered constantly and get hung up. But for most people encountering smoother rocks, and down trees it would work well.

This bash guard situation, is it on DJI or on Crestline?

The more I read about the DJI, the less appealing it seems. Noise, no bash guard, lower efficiency, weight bias issues, cadence instead of torque-based engine programming...

Those are small things overall. I tested it with a different (newer) motor and it’s a fair bit quieter than the last. The DJI has some big advantages over the rest of the market.

BTW, it’s not cadence based. It’s torque based. Just need to play with settings: Avinox Motor Tuning - Tips Thread

Truely. These are nothing burger problems if anything at all. They're starting to get out way off base factually. Gotta love the internets.

All downsides of any EMTB motor and bike are often ignorantly and massively overplayed by people who don’t like them for whatever reason to be fair.

People just need to get off the transmit button sometimes and go ride the freakin things…
