Sam, have you had a chance to ride it on a narrow road where one wheel is occasionally in the dirt/off the pavement?If so how did it feel/track?I still don't know if I should get the single wheel type.
yes I have rides great, I have even had it on 100% grass and rides is real smooth like it's not even haven it there.
On the road and Grass even speed bumps ,No jumping around smooth turning .
I don't thank you could build one as good of quality for the $110.00 it would cost you more then $110.00 in time and labor.
The covers made out that man made fabric like outdoor chair cushions are made from, no zippers to break it Velcro's on.
the trailer side covers are attached to the trailer no loosing them and helps with keeping thing in . Unlike the 16" trailer
The top Cover fits real tight .
the 20" tires are well wort the extra $10.00 I also thank the cover you get is far better.
If you get on go with the 20".
What I don't like
The top cover should have 4 tie straps so you can tie the top down it fits real tight but just encase the straps would keep it from blowing off.
The fabric is not water proof .
should of had reflector on the back not just the sides
these thing I can fix myself.
Over all yes I would buy it again. and could not be any happier
