Inviting comments on my latest creation; almost 2 years into it so far.
This started its life as a tadpole scooter. The previous hacker put a 20 inch rear wheel off a kids bike on the back. I removed the 10 inch diameter go cart wheels from the front and put 20 inch hollow hub wheels, changed the rear end to take 26" 3 speed wheel and a banana seat. The recumbent style stem/handlebar combo replaced the apehangers. It can be riden sitting or standing and my little can stand just behind the steerer tube.
