well,
price tells everthing.
my battery 36V10Ah alone cost me more.
my TF made-in USA cost 4000 dollars, but it is trouble -free for 13,500 km.
the best ebike kit E+ /Google it/ is over 2500dollars.
I don`t know why would people expect reliable mean of transport for less than 10 tanks of gasoline.
Pay at very minimum one year worth of gasoline - 12 times $70 is....
Do you want reliable or have your hands dirty every day with crap from China.
