If you search thru the thread TC did find a US source for custom ti bolts but it is pricey.

Not possible. The Bafang charge connector is only designed for 2amps, the wires are not big enough to handle the current to drive the motor.

I have a webcam in their office and I see everything they do.

I think you do fine but just realize you may need to adapt a little, more rise on the handlebars, stem changes, seat forward or back. You made have to select a different frame size than you previously used. You will have to "neutralize" some of the LLS geometry to make it more trail friendly.

More importantly what kind of riding have you done? MTB has shifted towards Enduro which is riding down. So the geometry has shifted such that the rider sits back to make it more comfortable going down. This makes the top tube longer, that is why they all use short stems. So if you are a trail...

Obviously if you buy from the manufacturer you can get what you want instead of buying from a reseller.

From BAFANG motor source.

Yes

If you do want to do this then Grin is close to you and they know what they are doing. But as noted, airlines are flakey in following their own rules and many gate agents don't know the rules.

What kinda travel can the Woom 3 have Here it comes "daddy can I have a ZEB 38 for my birthday?" :)

The cup should not need to be glued in. The ZS zero stack cup presses in like any other pressed in cup. Then the bearing just drops in. The only reason that the cup might be glued in is that the headtube is not properly round etc. I would inquire to szzs as to why it was glued in and what kind...

I don't build my own battery packs because it can be dangerous. That said yes you need the full voltage required by the specified motor voltage. But you can get there any combination the ends up with 48v. I can't answer any of your other questions. Another approach, although it might not be...

Friuli-Venezia Giulia or Alto Adige?

I will give you that if you are riding motor out of the design range then 48v is going to allow you to run more into the red zone. The M820 is a lightweight low power motor in anybody's book. Every other motor in the Bafang range has more power. The BBSHD is a 750w motor. It is all a matter of...

neither the Shimano e8000 nor the EP8 is a full size motor. The Bafang 620 is a full size motor. The effect of the heat and how it is removed does make a difference. It would make no difference how much heat was produced if it was all removed by cryo cooling etc. The heatsinking is there to...

The m820 is not a full size motor and I don't buy the 78% less heat at 48v. The heat affecting the motor is dependent on the heat sinking. You can't calculate the potential heat savings without taking into consideration the removal of heat. Just compare the weight of the M820 compared to one of...

from JimLee's conversation with Bafang. "About the DIY battery, lots of peoples want the bigger battery, 720wh, 840wh, 960wh, the more the better, but please note, 1. This is an electric assist bicycle, electric energy is only auxiliary and should not be the main force, Use your feet to move...

All the conditions really need to be known before one can speculate. Bafang said that these were not designed to operate in Boost for extended periods of time.
