Curious about M820 motor noise too!
410Wh, bafang BT F014
60% (3/5 leds) remaining? Excellent30km, 960m elevation and had 3 leds remaining
Is that in general? or specific to this frame. please tell me more.42mm, I don't like the handling of 51
Noise is perceivable but nothing really disturbing for me, but not a TQ motor for sure. In turbo mode its a lil loud.Rocky boost mode?
Noise during climbs and turbo modes?
Thanks in advance.
Wow...Too loud??To me the noise levels are very worrisome.
What can be done to mitigate it?
After market nylon gear?
Worth re-greasing like the larger older motors?
Could sound proofing squeezed in the frame possibly do any difference?
just checked and I still have 2 leds left, so probably a 50km route with 1300m can be easily done, enough for me30k on a 410wh seems like good range!
wow, impressive for a small battery like this! Very excited to get the bike (LCE930 for me)just checked and I still have 2 leds left, so probably a 50km route with 1300m can be easily done, enough for me
I don´t have mine yet but I'm worried.Wow...Too loud??

Forestal told me by e-mail that their motor is unique to them and is not just an M820. I would have preferred it to just be an M820 so that rebuilds, and replacements were available for many years. Truth is that Forestal is much more likely to shut the doors rather than Bafang.
Is the Forestal motor the same architecture, but with different mounts? Is the exact same motor but with Ti shafts, etc. I don't know?
As far as the noise goes, well the new Levo SL uses a honeycomb structure on the new casing. Some insulation might be the best path forward.
I will admit that reports of high noise were the primary reason I blew off purchasing a Forestal frame set, which they are selling now at reasonable prices.
I think somebody weighed 'em already that had a M820 motor....cast alloy 170 mm at 460-480g ish. It's posted over at the M820 thread.Maybe someone could, hint hint Tom, weight the standard Bafang cranks to help determine how much can be saved buying carbon cranks. The weight and the price of the Miranda is very tempting.
ALso the offsets like in the drawing above to determine which set of cranks to get.
Well maybe it was more 400+ g. It's on that thread about 2 months ago. You should be able to find it.Even 460-288=172 nearly 6 ounces savings.
That's big grams savings!The weight Karokonig reported was 498g!
Your weight on the Hope is 465g.
498-288=210 or 13 ounces savings with the MIranda. But not sure what the Q factor would be 8 or 16? Not sure how that specification is measured
I bought these levers. They will arrive in 1 month.I got a fast reply from Miranda via email.
That is LIGHT!Carbon Fiber Cranks 165 Q:8 FB Isis Standard (Black) for E-BIKE & MTB & ROAD & TRACK
What's included: Right and left crank arms, installation boltsmirandabikestore.com
"Hi Mike,
The weight should be around 288g the pair.
The FB has a head a bit taller.

The only problem is that MIranda makes a lot of cranks so it depends which one he was measuring. I think the Q8 and Q16 are different and the previous diagram is the Q8. What was the crank Karokonig comparing?He also measured the Miranda Carbon 165mm standard (not FB) at 312.4g
Also measured 12mm wider inside crank - inside crank, at the pedals.
This means more chainstay clearance than the standard Bafang. No need for FB version I would think.
If you went with FB, it will be 15mm wider than oem.

He went on to say the cranks work no problem
OEM is not on sale. I had to buy FB.He also measured the Miranda Carbon 165mm standard (not FB) at 312.4g
Also measured 12mm wider inside crank - inside crank, at the pedals.
