Amflow PL Carbon "weight loss"
- Thread starter Newchurch
- Start date
Looks to me OP convert the bike into an XC or nearly gravel.
I can see the idea then to me the next logic step would be not to remove the fork for something way less burly. I bet a Fox34 would be far sufficient for OP with 300-450 grams lighter.
There is no really any use of either shock and fox with 150mm to be honest with that type of riding. You could reduce rear and front travel too and towards fox 32 but that could be complicated (geo might be kept?) and surely expensive - unless you succeed to sell stock parts. Then you would definitely reduce by a lot the weight!
As other mentioned I would go totally the opposite way
170-180/170 but definitely not on amflow frame.

This is a fun project, thanks for sharing OP.
My concern is that this motor is so powerful, and that the bike is set up for some pretty tame trails, and the bike with those tires is going to roll so easily, that you are going to spend a LOT of time against the speed limiter and that's not really going to be very fun. 25 kph is possible to maintain on easy trails, on any XC bike, a good portion of the time. I think you are going to be bored. I also suspect that you will barely use any battery juice.
Recently I rode with an older gentleman riding some pretty flat, but still chunky XC trails near my home and he was on the Pivot SL with the Fazua 60. I was hauling *ss that day and after I passed the bike I was surprised he was able to keep up. When we stopped, I found that he was a very experienced rider on an e-bike (I was riding my Smuggler trail bike, not my e-bike). He was running Ground Control tires, the bike was full weight weenie, and he had a CF seat post (no dropper) as well and he told me the bike weighed under 38#s ready to ride. (17.27 kgs).

I do agree that an XC bike of 10-11 kg is gonna rip anything, if you are healthy, the major reason I could see the benefit of adding a big mass of motor/battery would be that, health limitation. Ok the only other reason would be OP doing tons of climb without any fun, then it could be a good option.

I have a 10 kg XC bike and a Bulls Wild Flow Evo with Fazua drive train. Weight of the Bulls was 16,7 kg with nearly identical parts like the Amflow now. My health is ok, it is the "more fun" with an eBike and especially the Amflow with Avinox drive train is a great bike for someone, who is interested in the new motor.
Bonjour bravo pour votre montage pouvez vous me donné le poids des roues carbons je pense aussi me prendre un amflow et le rendre plus léger merci
Je trouve sont montage assez cohérent pour 18,460kg sauf les pneus bien sur , il va bien sur économiser de la batterie avec ce montage
You could potentially climb on an 18kg bike, even without a dropper, with amflow power and have vast amounts of fun !
Plus, if you were fit, you can still just lower the post as required manually.
I run switchgrades, which aren't cable operated, but you still adjust as required - though obviously not as intensively as you'd use a dropper when you're trying to ride optimally.
@Zimmerframe I don't think I can ride any mtb bike without a dropper. That said I take absolutely no pleasure climbing, total waste of time for me, from analog to full power it is just a mean to an end and a time I am wasting doing something I don't like
I ran switchgrades since 2 week, late Christmas gift, and am not totally impressed yet. I find it a bit clunky to operate, one position is also harder than the other (one pointing down - but no screw touch anything I think).
It is not as easy to put it in neutral position to me, I do agree the climbing position is that said really nice on my butt, for dh, jury stills out. I need to see if I would be better off on the 2 positions.
Could be new muscle memory to build, I have it so I might use it but it is a bit heavy too.
I still could not personally ride one without a dropper.

I think you could physically ride one, it's just you wouldn't want to ride one doing the riding that you do. I think was your point.@Zimmerframe I don't think I can ride any mtb bike without a dropper.

Without a dropper post you would really want to stick to easy trails. If it got steep and or technical, not being able to drop the post would be pretty sketchy. Same goes for those lightweight tyres. On smooth easy trails they wouldn't be a problem but if you rode them on something rocky or muddy, it would be a problem.
As I said before, it's his bike and he can do what he wants to it, but it does seem a bit of a waste of a reasonably capable bike to then make it less capable.
Anyway, best of luck to him and I hope he enjoys it.

Exactly - thanks
They come standard with Avinox as that is the name of the DJI drive train ;-)

Next mods should be drop bars, a carbon strut to replace the rear shock, then a set of gravel suspension forks and wheels! Think of the weight savings man!

Thanks for the pics. Fantastic looking bike. Couple of questions.
Are they 2 pot XTRs ?
Are you not worried about going over the handlebars when descending, with that seat so high ? Also. Do you feel confident being that high when descending on rough terrain or laying the bike over in berms ?
Also for us.
Really interesting topic, I considered doing something similar if I purchased an Amflow (but with a dropper 
). I ride XC trails and fast single track, don't do jumps or hardcore downhill so light weight makes a bike more useful for me. My Rise weighs 17kg and is the perfect balance of power and weight (although never use turbo and mainly eco, so really more power than I ever need). The reason I didn't bother with the Amflow is I don't need more power, as someone else said more power will just get to the speed cut off sooner, it feels like this amount of power would be a good fit on a 24kg downhill setup. That's not to say you have to use all the power, the OP would likely ride most of the time in lower modes, but then you are carry a much bigger battery than you likely need and only using levels of power which other motors could offer.
Anyway, I like the idea, I always pull weight out of every bike I own due to the type riding I do, but the power this motor offers would be wasted on a light build for me.

As mentioned before I don't use the bike for hard trails or downhills.
Maybe most of you think the motor power is not necessary for such a light bike, but if you want a light eMBT with the Avinox drive train you have actually no other way to buy a Amflow PL Carbon and modify it in that way.
Go by foot without a bike - saves more weight

😠 Donald Duck 😠
why do you "need" so much travel then?

then change the fork to a pike/34, and use a lightweight air shock without reservoir with the shortes stroke available to make it make more sense
--> keeps the ride height the same, but reduces travel in the rear by a lot and removes even more weight

Ok. That explains the brakes if you only use it on flat terrain.
My only advice is to make sure you keep the original parts. If in the future you decide to sell, I suspect with only 2 pot brakes and no dropper. It would be hard to sell.
But for your usage it would work very well.
Peut-être qu'il a perdu 7 kg avec un régime et avec les trois kilos qu'il a gagné sur son vélo ca fait 10 kg de moins donc il fera 5 km de plus avec une batterie de 800 whInteresting and expensive project...but it would probably be easier and cheaper to lose 3kg of your own weightunless you're already a skinny ass dude
Hello, how much do your new wheels weigh?
cool thanks and congratulations for your editing
