Question: is the handle bar height adjustable on this item?
Document: The shipment arrived quickly and without damage. It did not take too long to assemble. The assembly time in the instructions was fairly accurate due to the tools limitation (no power tools so it takes a wee bit of time to twist and turn). It was very nice and my grandson loves using it. DEFINITELY needs a helmet since you can pick up some speed going downhill. I liked that the handle bar could be adjusted up and down depending on the height requirement.
originally bought a pink powerwing flower design. nice product, but my daughter is a little taller for her age. she loves this and the adjustable handlebars really help in the height. recommend for other buyers.
Having the adjustable handle is a plus.
My 8 year old loved this when she got it for Christmas but the bar from the front wheel to the handle bar fell apart within a few weeks.
You have to bend back a part of it at the bottom of the handle bar part (I am not a technical person as you can see!). It will expose the part that needs to be threaded down into that front wheel.
DD asked for the powerwing for Christmas. I ordered the Deluxe model since she is 12 and needed the larger size and adjustable height. She loves it and is very happy. She has been using it outside even though the weather is only 30 degrees. I imagine it will get a lot of use as the days grow longer and warmer.Overall, happy.
If you loosen the bolt near the bottom of the handle bar, the scooter basically folds in half, making it easy to fit in a trunk for transport. For a while it was the coolest thing on our street, but that title now belongs to the motorized scooter a few houses down!
My daughter recieved this for Christmas. She figured it out right away. It folds up nicely for travel. The one thing I would note is that the handle bars are just one height, there is no way to raise or lower them.
I purchased two, one for my 5 year old knowing he can grow into it and one for me. I wasn't sure if it would be to big for him but this is the only model that has an adjustable bar so it worked great. He needs to put extra effort in the break due to his size but he has a blast. I wish the wheels were not plastic many times riding the wheels will catch on a small rock or ledge and I'd go flying forward.
My 10 year old son loves this scooter. He got the rip stick last year and just couldn't quite get the hang of it. The Powerwing is much easier to use and WAY safer. He also has a razor regular scooter but rides the Powerwing now all the time. I would highly recommend it. It was easy to put together too. The only drawback that I see is that the height of the handles is not adjustable like the razor scooter.
