I bought 2 there--loved the bike but never found a pump that would work so i had a wheel built with steel spokes--cost $15,00--still got flats each time I rode the darn thing so I had solid tires --used on motorized wheel chairs put one--no flats but it added weight--more i look at the Strida i think some of it's parts can be used on the microbike--biggest problem I had was that there just where no decent tires--seemed it used regular scooter tires which where like peanut butter--
but, what a fantastic bike compared to the folding bikes i see here in New York City--also the clip that held it together was a disaster--always snapped--the bike need just a tid more engineering but I have no complaints
kind of neat to see it mentioned on the net
