Re Birdie compromises.
Well all folders make concessions. Even 4k ones.
Wheel size 18
Steering stability due to front fork design. It does help it fold and yield nice anti drive characteristics.
Folding size limitations, its tiny to pack with wheel removed however.
Touring rear panniers must be small to aviod heel strike or mounted far back meaning the rolling wheels need to be removed.
Hard to set up vbrake noddles at front.
Chainwheel clearence is minimal on frame when folding and rings can get bent.
Clearence issues on wide tyres at back.
Old chain cather can wedge in transmission breaking draillers etc.
The last three issues seem to be addressed by mk3 improvements which i have fitted to my bikes. Ie small cage drailler and chain tensioner with no catcher.
Flawed but genius
And enjoyable.
