Bipolar - a double-pivot folding python

Here goes a bicycle version of the Skatecycle, • Video , same folding requirement as the μPython, • μPython - a micro fold... , to fit in the back of small car boot with seat up. For 20" wheels, double-pivot folding mechanism is used for max compactness. The seat is split into 2 pieces, with the backrest mounted to the rear pivot to control the rear wheel, which makes this bike all wheel steering (AWS), with rear wheel turning only when the body leans into a turn. Turning feels tighter and smoother than regular python; going straight is not too bad, but instability seems more sudden / unpredictable...

This video could have been so much less weird. Thanks for making it weird.

brilliant

Angle test was done last year, 44-70 deg with other bikes. 60 seems to be good compromise. Seat was improved. A lock was added to hold the wheels together when folded, but not very quick to release or fold...

not very well, because the COG is toward the rear (for compactness). Other bikes with COG toward the front climb really well.

Any more done on this?
Did you try messing around with different steering angles and such?
