He wants relaible ebike
Cheap Anderson connectors
Motors allowing water in
wires too thin on motors
motors that destroy themselves on overload
Typical "battery meters" which shows empty or full and not much between
crappy duct tape batteries
That is not reliable
to me
Maybe you have different tech standards
One kit comes to mind
FALCO motors
designed to Western standards,manufactured in India.
Sold by Team Hybrid in England
Again,
You cannot go wrong with made in Canada ,software-driven BIONX .
Of course there a way to replace cells yourself in BIONX battery.
