I simply love it. The Half Bike 2 came very well packed from Europe to the US. Was delivered on time. It took me 1 hour to assemble following the instructions with the video on my phone.
I grew up in Paris but now live in the Chicago suburb so I take it for a ride in my neighborhood. My kids are 15 and 12 and use it as well. It took the three of us a few tries on my driveway but we were able to ride the bike within 15-20 minutes. I feel that knowing how to ride skateboard helped us a lot to start gliding with it. It is such a different experience than riding a bike.
Now we take the half bike for longer rides (it is more a workout for me than it is for my kids) and we enjoy it a lot. Every ride gets easier. Great invention. I am so happy I bought one.
