May not work as you tires are not the same size. Also you are running gears and mags are not designed for them. This is what you need to figure out if the swap will work. The tires you have, have a second set of numbers like 28-559 and the 559 number is the bead seat diameter, and you need to see if it is the same bead seat diameter as bmx 20". If it is then you need to see if the tires will clear the frame since there 2 sizes wider and the 20x1.75 is the smallest tire needed to fit the mag wheels. If that works then a longer axle and spacing for the gears. But I am not sure if they do the freewheel rear hub but probably so.
