I modified a züm bike I purchased from EBay. I bought a third rim to match and converted the bike into a trike. There will be many videos to follow, of that I am sure. This is now a 3 in 1 push/strider bike. This will convert from a trike to short bike (flip the sloped bar) to tall bike.....skip the training wheels and straight to a bigger pedal bike. I am so excited for this summer.
