I have never ridden a beam bike, but noted sitting behind a singleton with a beam that the rider yo-yoed up and down with road
undulations on smooth asphalt. This may be fine or not, probably good for rough roads or off road, but an acquired taste on smooth roads.
A lot would have to do with beam spring constant and rider weight. Dunnoh if this is adjustable or not. I suspect at certain
cadences the up-down would magnify. Front compartment looks a little tight.
