Yep, those are the best options trying to find one for the best price.

For what's it worth. My understanding is that Float X 2022 and 2023 are the same. Maybe a new '22 out there with a deep discount.🤞

But the new RS has a sweet bottom out adjust button (purple) for aggressive riding (a new feature that better mimics the big negative aircan of my megneg).

That sounds similar to mine, I don’t think it’s an issue. But once you hear it you can’t unhear it. Just know that it’s normal.

I observed the same with my M510 on the E10. I think it’s the sprague bearing (one way clutch) that has some play. Running downhill, the chain slap working against the sprague bearing is causing that rattling noise. I use this simple chain tensioner device, significantly improving the noise level.

How come they can not do one way clutch which is not making any rattle? And not even Bafang. :(

M510,M600 is fine. M620 is rattling a lot.
 
Got my frame rolling. Was my first E-Bike build and it was a bit of a challenge but it seems like quite a nice motor platform.

Still need to change out the headset and do proper cable management and water proofing.

The cane creek DB IL doesn't fit, unless your willing to take an orbital sander to it. I got it on sale for 200 so i figured why not. I also needed to sand down the inside of the seat tube some so a 200mm dropper could fit in.

It could vary quite a bit depending on your experience and luck. I wasted a lot of time polishing a small lump blocking the seat post with sandpaper on a stick. The carbon is quite hard! I finally grabbed a sanding drum and put it on my drill driver with a 12 inch extension and ground it down in a few seconds. I also reinstalled the battery and motor multiple times to get the cables in a somewhat clean configuration. I worked on mine for most of a day and after a fun but short ride on the greenway realized I still needed to tune the suspension, brakes and possibly the chain line.

Good improv skills and practical determination on the shock fitment. 🤟

Well done!🤛

I had the same issue. a very small 0.2mm epoxy/carbon ridge a few cm above the charge port. I carefully used a long rounded file. took a few seconds. very easy fix in the end. I have to say, the insert length on this frame is very impressive.
Not being able to slam the seatpost down would forever frustrate me.

I also spent half a day filing down a chainring lockring tool I got from AliEx. The teeth spacing and width was spot on, but the diameter was out of spec. too small. I had to file the inside of each tooth to allow it to fit over the lockring.
*LPT use a multitool with a grinding disc/stone.

I had exactly the same issue with Unior ISIS BB tool. Is it possible, that bafang lock ring has different nominal dimension than standard ISIS?

I decided to file down the lock ring, because it is made from aluminum, and my tool is from carbon steel. It is significantly harder. Even filing down the lock ring took longer than I anticipated. Hope I didn't weaken it too much.

Got the new display. Are there limits to what you can modify in the profile. I wanted to change the wattage ceiling in mode 3 (sport) but it’s not letting me. See image below.

Also what is the startup angle?

Start up angle is the angle of the cranks for motor starting to give u power assist. The less the quicker give u power.
 
I don't have BESST tool or GO+ display. So I'm just guessing.
From what I can see, the GO+ app is a cut down version of the BESST tool, an end user version.
If you read the BESST tool user manual, you can see the corresponding settings and descriptions to the GO+ app.
I think it should help.

For what it's worth...updates for those who still don't want the top tube cap....ain't gonna happen!😝

It's the same on all mode ? does you have on display 1=E, 2=T, 3=S, 4=S+ and 5=B ? or 1=E, 2= E+, 3= T, 4=B, 5=R ?

My guess...
the settings of a lower mode cannot be higher than the settings in higher mode.
i.e if Mode 4 has 65% then Mode 3 cannot exceed 65%

This is the case as well with the BESST tool. I tried to set lower speed limit in TURBO, but make it higher in ECO, but it did not work.
