I tend to distrust things that connect to your smartphone. Seems like a new way of tracking another parameter of our life. However, the machine seems interesting. If I road a bike regularly I would probably be all for it. I wish they had said how fast it would help you go.
dunno if it mentioned top speed or not.
ditto on the smartphone app...I'd disable it.
I just like the way it sits down on the tire and pushes.
doesn't seem all that hard..bet I could make one.
Ya it's super clever! Good find
