Iseebiz 1 Pair Training Wheels for Ninebot One C C+ E Electric Scooter Training Wheels Assist Wheels Balancing Unicycle Training Wheels

They are ok, but for $60 one would expect better quality and more futures.For example to put them on you need to have a screwdriver, they should be have some sort of clamp, so it would be easier putt it on and take it off.Also, as you drive around they get loose to easily from vibration, not well build.

I attached it to my electric scooter and it helps me balance my 250lb body on the scooter.

Works great.

Works perfect

These do not fit a Ninebot S1. I had hoped to speed up the learning curve with these on my S1. The aluminium parts fit fine but the plastic clamps are for a different Ninebot ( maybe the S2 ??? ) I could make a bracket that would work but at $75.00 they should fit. It would be nice if in the description they would tell you which model that these do fit more clearly. Great Idea! Poor product description.
