Hi Friend,
I am going to tell you about my Yo Spark. I bought it in 2012. From then it gave pleasure of riding of ebyke. It seems to me a really money saving two wheeler. But after 4months it start showing its disadvantages. First of all rear suspension is uncomfortable. Secondly, rear wheel is it's engine i.e. motor, if it is punchered then you will find most shocking experience to repair it.
Third, capacity of batteries start to decrease after 1 year.Fourth, if you drive in a rough road then you may have change it' converter frequently etc.
