Hey guys, Im new to this forum and ebike building...

Im thinking about building an ebike to commute to my local train station before and after work. Its around 4 miles in total, each day.

For the bike, im thinking of buying this: argosDOTcoDOTuk/product/6007870

For the conversion kit, im thinking of getting this one: ebayDOTcoDOTuk/itm/323199246084
Im not sure what battery to get?

Maybe this one? amazonDOTcoDOTuk/Downtube-Battery-Lithium-SAMSUNG-charger/dp/B01JPM58PU

It uses Samsung cells, so no chinese batteries.

So i guess my questions are, is the battery ok? If not, can you suggest one please.

Also, is the voltage ok too?

Also, in terms of the wiring, will the battery connect to the hub motor with no issues?

Im not allowed to post URLs, so replace DOT with an actual dot.
Thanks
