How do you get chainring protection on the DJI Avinox motor? Searched and can't find anything.

Lol you dont have a clue if you think its about bunny hopping
It is, a little, but it's also a joke. Relax. But I am curious to see an example of a feature where a bash guard is a must have or getting off the bike is the only way past.
 
People seem to forget that a mid drive motor is completely different than any traditional bike. The chain ring is now attached directly in to the fragile motor drive....NOT in to the right crank and beefy, easy to service, bottom bracket. Impacting a chain ring previously would only damage the chain ring. Impacting one now sends shock directly in to the difficult to service motor drive!

yes, exactly the same as without a bash ring, your point is?
 
Ethirteen have just launched a bashguard that includes the chainring and spider for the Amflow called the Turbocharger.
Here are some pics of it on me and my mates Amflows

if anyone wants to take a look here is the link to the ethirteen website:

Its exactly the same as when people started wanting shorter cranks. There isnt many single objects you cant get past with 175 length cranks so why dont you mount those?
Because its bloody inconvenient some places and if you insist on not running shorter cranks or bash guard or dropper post or upgrade from 26 inch wheels be my guest! I could not care less and i wont tell you how to ride or not to ride. Now I just wish you had the same courtesy.

Fantastic! Problem solved.

It does add 220 grams which doesn't bother me in the least, accept it does erase a lot of the weight advantage that the DJI held over the Gen5. Just an FYI, as it's 100% required imo.

I actually do prefer this sort of bash guard rather than the entire motor hanging down like the Bosch because not only does this look better, but there is just a lot less area to contact.

Only issue: they need one for a 36T!

That looks counterproductive for what I believe is the major goal of protecting the motor. Beefing up the chain ring with anything mounted to the motor shaft will only increase the shock load in to the motor shaft. I would much rather bend a chain ring.

Point is that the chain ring damage is not the real issue. Preventing shock load from the motor is. So bash protection needs to be frame mounted or the chain ring needs to not hang down below the frame skid.

I preach this from the mountain top. I'd rather replace a chain or chainring than a motor. MANY cases of people slamming thier crank into the ground and damaging the motor.
 
Im still on the fence. If the impact is hard enough, no chain ring or bash guard will save the motor.
But im not sure if 100 eur is worth maybe trashing the motor, to save something that cost less than 100 eur
 
I think you guys are absurd with this notion.

Bearings can take 10000+ psi. You land from jumps all day long putting high loads through the motor. When you make contact with the pedal (happens all of the time to me) or the chainring bash guard, the shaft and bearings in that motor support your bike and body weight from coming down further. Seriously, big effing deal. My F60 came stock with a bash ring like this, and frankly for some of us the Avinox is all but useless without a bash ring.

How often should one be walking out from the trails? Sheesh.

I want a bash guard as much as anyone, if its safe :)
 
If you feel that strongly about not using a chainring/ crank mounted bash guard, but you are one of the ones that needs a bash guard, well it sounds like the Bosch is your only choice.

For me, the E13 option makes the Avinox more viable. Still, it has noise, efficiency & power delivery issues that I'm not certain I can get past.

I dont.
Im tempted to try the e13.

I like the motor, i think the only not so great thing is the rattle, but after tweaking settings, maybe its not a huge issue. Going for a long weekend of rding in 2 weeks. Ill find out if it is by then.
 
Hey - saw this product today and wonder if anyone has seen it irl. It sounds like it’s included in SRAM ebike transmission groups. It’s a 104bcd chainring and integrated bash. Other sites make it sound like it clips on, in which case… I’m skeptical.

I fitted this homemade wooden skid block about 3 months to protect the chainring and chain from rock impacts. It is working really well.

I just cut it out of a piece of timber with a jigsaw. A bit of filing and some paint. As you can see from the imprint I've marked in red on the timber. Impacts from bottoming out, dropping of rocks, have pushed the block quite forcefully into the motor fins. But there has been no damage to the original bashguard, motor or chainring.

It is not really visible when the bike is up the right way. (Which is most of the time ...... :ROFLMAO: ) So aesthetics were not as important as function. And it's doing it's job without any side effects.

It's just fitted with 3 tek screws into the timber from inside the guard. You can see this. This is also working well. A replacement bashguard is only AUD$17. So it's not an expensive mod if it fails and you want to return to original.

Short version is that I wouldn't run one, as it will direct too much force into the drive unit. You're better off trashing a chain or chainring than your motor.
I've bent the spider arm and the chainring without it. That ends your day and gets expensive. It also transfers an impact load to the motor axle.

I have not done any damage since adding the skid block. The skid block is a soft timber and gives a little. It absorbs some of the impact, and transfers the rest to the motor casing, which the timber block is resting on. Hence the fin marks in the timber. This transfers to the mounting bolts. This should be the strongest part of the motor.

Slowly the timber block will be eaten away, like a sacrificial anode. It has already started. Then I'll just cut another one.
 
In the case of an eMTB, it's a bit more complicated, as you risk very expensive (and non-warranty) drive unit damage if you install too strong of a bashguard. You want the chainring to fail before the drive unit does...
take a look into the velduro thread (last page atm) or check out the one from crestline, both use one thats also the motor cover

Looks like we'll all be running 26T chainrings soon. :cool:
 
Rode some pretty sketchy rocky technical sections today, and I felt the skid block take a decent impact. Checked the bike before loading into the car. No harm done. Just a scratch on the skid block. But most importantly. Chainring, Chain and Spider came through unscathed. This is working nicely.
