My second order to Linda with common cable routing through frame. Will be using 48v system for this, Linda said battery is lighter than 36v cause it's using different case. Let's see.

Just got back from a week' s long riding trip. The trail-system (Phil's World, Cortez, CO, USA) has some fairly flowy tech with scary, rock slab drops on some lines that I survived...barely!🤙

Before I left, I painted the rocker arm/linkage area with a thick coat of black paint pen. No marring, pitting, or chaffing after a week of hard riding. 👍

Seems like the 55 mm stroke works with my 210x55 RS MegNeg.💪

I just painted my warranty front triangle before my trip. I'm now ready to disassemble my rear linkage and paint it. I'll inspect it further for any cracks, weakness etc. and report on it if something is questionable.🤞

That color scheme looks great. Nice work!

Another question, I noticed the other night that I was able to keep full power below 30%. The system allowed me to keep full power down to 25%. I was done with my ride at that point and it was dark so I I couldn't take it to the drop off point. Has anyone else noticed this and is there a built in "burn in" period on these batteries such that after X amount of recharge cycles it considers the battery broken and allows it to go lower than 30%?

Power decreases after 20%

I just got a quote with 36V and DPC245 V3
not only of course. But when i have ordered m820, they have change DPC245 to rev 3.0 when they have change 36V to 48V. It's the raison why i suppose that only rev3 can manage 48V. but i can't certified

Just spoke with Linda. They're preparing a new rear triangle that uses the UDH instead of the custom hanger. this is AMAZING news!!!

Also commented on modifying the lower shock mount to move it 1cm further from the seat tube to allow a coil shock to fit.
I'm really happy on how good the post-sales service is. Impressive!

Park BBT-18 to tighten the Bafang Motor lockring.

How did everyone tighten the motor bolts with the nylock nuts. THe openings are too tight for a thin-wall socket. I used a big flat blade screwdriver to jam the nut from moving but it pained me to do it.

Ask her to send you a set of allen key motor bolts. I asked her to send me 2x sets of motor bolts and she sent me the original with nylock nuts, and another set with allen key bolts.

Looks like these guys are slowly building my dream bike.

UDH compatible (not running SRAM Transmission. but I do like a standardised hanger)
Coil shock compatible (not going to run a coil, but I like the option)
Carbon battery case (instead of the currently 1kg monster)

I'm really impressed with how they listen. I think I'm going to buy another frame.
Pretty soon we can have a bike built like Homer Simpson's car. Oversized cup holder anyone? :LOL:

It makes no sense.
I always thought the displays were auto-voltage-sensing (is that a thing?) or am I wrong?

It usually has a voltage regulator, so if it supports 48v, it’ll support anything lower than it.
Data goes through can and pretty sure every ic in the display is 5v or 3.3v driven
