Hello everybody,
As I recently somehow attained quite some money, I decided to approach my first E-Bike build.
I attached my basket screenshots at EM3ev and Luna Cycle and hope for a little bit of help before pressing order.
Furthermore I'll probably going to buy this bike:

and these items:
https://eu.nkon.nl/rechargeable/18650-size/samsung-inr18650-35e.html
(I plan on building the Battery myself, probably 14s6p , 84 Cells)
http://vruzend.com/product/vruzend_basic_kit/
(because I don't own a spot welder and lack serious soldering skills)

(I thought about a bluetooth BMS)
I'm still not sure about some things:
1. First of all, do the Components work well together (especially the Cells and the BMS) ?
2. Will the Cells and the controller fit into the frame bag ?
3. Do I need the Wattmeter (if the bluetooth BMS sends me informations about the status of my Battery to my
phone) ?
4. If you go to Luna Cycle, there are two customer reviews on the Charger (international Version). One user
complains about the build quality and notes that there are potential dangers.
Does somebody have experiences with the international model ?
5. As You can see I'll use a bike with 700C wheels, on EM3ev is says that the MAC 12T will make about 32 Kph on
48V and 26 inch wheels. I imagine the bigger wheels and the higher Voltage will make it a bit faster.
Can somebody estimate how fast it will go, also how far (I'm about 174 lbs) ?
6. Do I need more Cables ?
7. Is it really true that shipping on EM3ev time takes 4 days to Europe on express delivery (while the normal
shipping is 3 weeks and cost just 16$ less) ?
8. Finally, do I lack something (I'm aware that I'll need better brakes)?
Many thanks in advance
