Tikits can be rolled on one wheel when folded - for that matter so can many Dahon models - but I wouldn't want to do so over distances more than a few feet because balancing it on one wheel can stress your wrist. The Strida was designed with the idea of rolling it around on both of its 16 inch wheels instead of relying on one wheel or on supplementary skateboard-size wheels. The Strida is easy to fold but makes for a long package so it may not be the most friendly to take into a store. Then again I've read where some have pushed it along like a shopping cart instead of having to carry it in a shopping cart.
