Is there a weight limit?

They are for children so I'd imagine under 200lbs

I was told by jetson company to purchase these for jlr x 20 inch bike, has anyone used these on that bike?

The Spark Light-Up Training Wheels are made to fit bikes with wheel-sizes ranging between 12-20 inches. We hope this helps. Thanks for choosing Jetson!

Using for a jetson bolt. Will this accommodate 200lbs rider? Or do you have training wheels support for your riders 256lbs weight limit?

The Spark Light Up Training Wheels have a weight limit of 110 lbs and are not compatible with electric bikes. At this time, we do not offer any other training wheels.
