I tested this product at a Radio Flyer test event. The vehicle rides very well and has a cool and interesting design. The two different speeds allow for different ages to have fun riding the product. Very simple controls allow for great handling. I would test the durability of the accelerator tab, as it seems like it may break over continued use. I would also encourage further testing going up a steeper hill as I didn't get the opportunity to test going up a large hill.
