Poor quality
The kit works well , but several quality problem happened to me just after a few km: First , my controller crashed , causing by bike to make a loud noise , got it replaced by warranty , but 20$ of shipping Second , the battery crashed , got one under warranty , again shipping cost , this time 40$ All that only after less than 500km and less than 1 year Definetly a good working kit , but not reliable , and you have to pay the shipping for every single warranty part I don’t recommend
