Rear fixed axle? only one discs makes both rear wheel brake? so only god for off road?
Extremely high steering, hit a dead stop and goodbye teeth.
Otherwise interesting.

Hard to say ? could it have free wheel hubs ?

Extremely high steering, hit a dead stop and goodbye teeth.

Yes it could be a little lower and not keen on the handlebar portion , however it would seem to get lots of steering lock you need a steering column like this ?

Otherwise interesting.
Yes a lot of good engineering , quite light and seems very stable for such a high seat ?

If it had freewheel hubs the brake wouldn't work. The handlebar position looks adjustable. Looks like there's a couple of bolts in the central mount to nip the inner tubing as it slides up and down.
 
Good call on the brakes !

Its the vertical bars that don't appeal , I would prefer them slightly angled down ? /-\
