Hardline Products USA Wheels for Tots Training Wheels for Stacyc, KTM, Husqvarna, GAS GAS, and Harley-Davidson 12e/16e balance Electric Bikes - NOT compatible with 16e Elite model.

Nice and sturdy, easy to mount. Adjustable ground clearance. Hardest part is bending the cotter pins, would be nice if they came with hitch pins instead,

Absolutely perfect for a my 5 year old daughter. If you have any mechanical inclination this is simple to install and works great. Being universal, it should fit most gas or e-bikes. I installed it on a Jetson E-dirt bike and made it work as the foot peg holes are slightly smaller than the supplied hardware, so I just used some different bolts and she was riding in no time.

Awesome bike, no complaints from my 4 year old.

Great

Work just fine no issues

These training wheels are an excellent addition to the Stacyc 12E model! They fit perfectly and provide great stability, allowing my child to gain confidence while learning to ride. The wheels are sturdy and easy to install, and they help keep the bike balanced as they transition to riding on two wheels. I appreciate the smooth performance, and my child enjoys the extra support. Highly recommend for anyone with a Stacyc 12E bike!

This is a good set of 'training' wheels. They are strong enough to help keep the smaller kids upright until they get enough confidence to remove them.Certainly they are not heavy enough to be taking hills or whatnot, but for flat field training they are perfect.The instructions could use a bit more detail but they are clear enough.I see a lot of reviewers broke the saddle clamps. The instructions clearly state 12-13 foot pounds to keep them from breaking. I know not everyone has torque wrenches. I got everything in place but only snugged the bolts. Then I rotated the axel until the wheels were about 2 inches off the ground and tightened the bolts evenly. As soon as they were close to tight, I pulled up on the axel and only tightened them until I could no longer rotate it by hand and then gave each one a half of a turn tighter.I know the cotter pin 'stops' for the tires seem cheesy but we have seen no issues with them holding up.My Son and Grandson have been playing on it for days now and I have not had to retighten even once. Now, in my mind that means they are not making a lot of contact with the ground which is a great sign they already have good balance.Still, all in all I feel much better having added these for the Grandson. For my own kids I just through them in the field and watched them fall over and over until they mastered it. (might explain a few things) This is for my piece of mind as much as theirs.One more note. I see the pictures show the axel bend toward the front. Not a good idea. If they did bite into the ground that could cause the bike to hop into the air a bit. I angled mine to the rear for safety.

So they work perfect for kids on electric bikes that can't ride without training wheels yet. I attached them to a mx350 they install pretty easy with the instructions. We have to constantly adjust them back down they rise up after riding and it makes it very wobbly. My dad even checked to make sure everything was tightened down and they still do. My opinion they are durable but a hassle at the same time and overpriced. I bought them for my 3 year old son and he can ride the dirt bike with no assistance. He just makes wider turns and it gets stuck alot in the grass he just gets off pushes it then gets back on
