squeaker said:IMO the result of unbalanced leg movement creating yaw and roll moments What you need is a counter-rotating pair of legs - wonder if the MicWic suffers from pedal steer? (Looks like the yaw moments cancel, but the roll moment is doubled....)
IIRC MicWic used to be the UK importer for Linear for a while, and made a tubular frame Linear clone commuting LWB
