KINGSTORE Running

It's good, it does its job. it was frustrating to install because it doesn't work if it's not grounded. it also makes the ride more difficult, because it is a little harder to pedal and it is noisy, so I do not recommend it on bikes that are going to be used by children, because the noise it makes prevents them from hearing if a car is coming and they do not listen to you if you yell at them to announce a danger.

I bought this to install on my mountain bike, there is no possible way this will fit on anything other than a 10 speed or slim competition racing street bike. Mountain bike frames are way to thick. Maybe the manufacturer can add an adapter to this kit for thicker frames. Otherwise , they work as described.

I bought these for some motorized bikes, and at first was disappointed, no real instructions to speak of the Gen was coming apart with wires breaking away from soder points. I had to make my own head light bracket as what they send fits nowhere on the front of a bike.With all that said I looked up vintage photos of how/where to install cut and drilled a cheap flat strap from Lowe's for a mount and a touch of soder (my 10 yr old did the sodering) on the broken wires.....these work so much better then expected and there is a catch/release lever on the Gen mount to keep it from running all the time. Peddling you can feel the drag a bit but it lights up, running the 80cc bike motor these are as bright as motorcycle or car head lights as long as your moving.

dislike . no wire for head light . does not explain well enough how to insert wires

No instructions in box but figured it out. The lights aren’t very bright but they look really good on my classic bike
