## Questions & Answers

**Q: Does this come with training wheels**
A: This product does come with training wheels.  The only issue I had with this product was the assembly instructions were very minimal and not very helpful and the front wheel bracket/mount onto the tire was extremely tight and difficult to insert.

**Q: are the trainning wheel removable?**
A: Training wheels are removable on almost any bike.

**Q: how do you tighten the seat on this bike? we have it as tight as the screw will go and it is still coming out and spinning around.**
A: Sorry to hear that the seat is not staying.  Best thing to do is buy at a local hardware store what is know as a lock tight washer that has grooves and put one or two inside the bolt.  They cost about .25c.  That is easier and cheaper than anything else. Indecorate

**Q: Is this thing heavy? As in, walmart tank heavy bike?**
A: Don't shop at Walmart, don't know what tank heavy bike is. This is durable, sturdy bike that doesn't weigh a ton. Hope this answered your question
