There is only one frame style for the Biria EZ boarding
bicycles. It is a lot like a Vespa scooter look but without the bulk.
The frame slopes down near the ground between the handlebars and the saddle.
The ground clearance is more than enough for street or smooth path riding.
And getting on the bicycle only requires that you step over a frame tube
that is not much more than six inches off the ground at its top.
