powell

I agree with all above posts.
It is obvious.
For low quality department store ebikes you need knowledge , be mechanical fix person and have a tools. Not only common tools but also bicycle tools otherwise yu would have to use bike shops. Those Wallmart bicycle will not last long with no maintenance often right out of the doors.
cheap components require constant adjusting, tweaking and it never ends.
I own 3 ebikes , two of them $2000-4000 and one around $1000.
[HR][/HR]riding experience, it is all about it.
Example cheap $10 derouller no matter how you adjust will not switch with precision like normal $40-$50 one.
$10 means plastic body derouller which is not stiff.
And it is just one example, chaep wheels will get loose spokes all the time - on other end normal min$150 wheel will last thousands of miles without any maintenance.
and list of cheepe components goes on and on.
this way or another you will pay with $$$ or with your time spent and dirty hands.
don't believe that on 500dollar ebike you can ride and ride with no issues for 1000 miles , no way.
