Can we just use the wheels of Strida 3 to replace the wheels on Strida 2?
There is a Strida 2.5 here in Hong Kong which has a magnet on its front wheel. I think the former owner has replaced the original wheels with a pair of plactic wheels from Strida 3.2.

There is also a Strida 2.5 in Taiwan with magnetic clip on its wheels.
