Thank you all for all the information.
I finally got my Girlfriend & her 13 year old daughter to ride in my Becak but going over a humpback bridge needed a super-human effort to reach the top without them getting out.
We visited a local Carnival where I parked with the Steam Traction Engine, there are also pics giving a friend's kids a ride around the village.
I'm amazed that I haven't lost pounds peddling this thing, and on a very hot & sticky GoBike ride up a lot of hills breathing in zillions of insects, YUK!
Safe & sweaty riding!
