"...I have an old BOB Yak and think it's great for some purposes but they're not good for really heavy loads.

Why ... a trailer on which all the heavy stuff has to be loaded so high up?" @hembrow

Thanks for mentioning the #BobYak - I was trying to track it down to mention it.

The main advantage of a one-wheeler to me is it's stability. On (rocky) rough terrain that would tend to "throw" one wheel of a 2-wheeler, at more than a snails pace.

The builders' wheelbarrow shape is one that has converged on an optimum, from across many designs, because its weight distribution etc works and it is compact. Garden barrows, well...;-/

Builder's barrow in reverse, for a bike trailer, out of lighter materials, gives compact short wheelbase / lower c-o-g / ground clearance balance. Battery could hang off the back for weight distribution.

The Yak is a bit stretched for city and tight-space use, I think, but the long wheelbase gives it stability. I would keep grounding it here.

@alemppu Huh, mutta näyttää se Helkamakin pärjäävän. Tietääkseni vanteet ja pinnat on heikoimpia kohtia polkupyörissä.

Tietty jos ei halua latoa lisää painoa pyörän päälle, peräkärrykin on vaihtoehto. Mulla on itselläni #bobyak matkailuun ja hyvin se kulkee, mutta toisaalta on aika vempula käsitellä pysäköidessä.

Harmi, ettei kypärää ole vielä löytynyt. Toivottavasti ketjuun ilmestyy joku, joka tietää niiden valikoimista enemmän.
