It took some time to make the most of the donor bike, chain stay, pivot, seat mounts... The compactness requirement is met with the seat removed and placed on top of the folded frame. The chain stay flexes a little bit, but there is still a lot of frame clearance in folded position to add more tubings. It's ridable now and meandering a lot (delicate), even more than the Mini Python (wheelsize? 70deg pivot?), but a lot of fun. May become a big hit with kids... http://www.youtube.com/watch?v=7-d1LxGXCCI Vi ________________________________ From: Vi Vuong <vi_vuong@xxxxxxxxx> To: Python <python@xxxxxxxxxxxxx> Sent: Sun, March 27, 2011 9:16:42 PM Subject: [python] μPython Build A micro size folding python. The goal is fit inside a small boot with seat up, 36" width x 14" depth (92x36cm) minus some protective cushion. The removable seat should fit in that space, over the python pile. Pivot angle is toward the high end ~70 deg for max compactness when folded, not sure how it will feel with the small fat wheel, and heavy chain ring, almost a big ~8.5" dia (215mm). Donor bike is a Razor Rocket Pocket (electric mini motorcycle), 10x3" wheels, drum brake, 20-25lbs without battery and motor. Here is what I have so far, and should be done by next weekend... Cheers, Vi
