Whilst i’m yet to strap the uni to my bike (pedal power not motor power) i have
towed my uni behind my bike. I used to strap it to an old golf buggy, and then
strap the golf buggy to my bike rak. The golf buggy had bearingless wheels which
were well under 10 inchees, so at over 30km/hour on the bike, it started getting
very unstable. Still, it was a good way to make an entrance at the local
juggling meet. Surely motorcycle trailers would be pretty simple to attach and
would let you carry lots more gear - but I guess then you lose out on the
freedom and style of the basic motor cycle loaded to the hilt with circus gear.
