Ride report on a beach cruiser ? Is that even done ?

My daily 'when possible' workout rides are about 10 miles at an average speed
of 11 mph and I spin out at 17.7 all per Strava.
The gearing Is fine (18T-44T) but I must remember not to mash hard without first standing
when I need to get moving fast. The ride position is not kind to my knee's when I need big watts
while sitting but ok as I get a good spin going.
The handling Is nice at any and all speeds and the bike likes to stay around 9,10 mph.

I know better to compare this bike with my Trek Cross Rip 3 but I must say, Is nice to
put on tennis shoes and go without having to prep myself with Lycra, gloves, Jersey and clipping in.

I'm glad I got this bike and cant wait to get back to the Single track rides on my moutain bike.
This Hurricane business closed all my trails for the time being.

I need somebody to talk me OUT of putting knobbie tires on this bike and a 22T on the back wheel
and then taking It to the trails..
