"Another option in this space is this motor kit, available from Grin Technologies out of Canada. They are a big player in the DIY e-bike community and generally sell great stuff and offer good support. https://ebikes.ca/shop/electric-bicycle-kits/wheelbarrow/basic-electric-wheelbarrow-conversion-kit.html"
"Looks like this features a 32mm mirror. I run a 50mm mirror on the end of my flat bars, and I wouldn't want to go much smaller than that as the field of view gets really small and it is difficult to get the mirror positioned just right. Also, the ability of the mirror to open and close seems a bit gimmicky to me. It is a very precise job to get one of these mirrors adjusted to just the right spot so I would not want to be opening and closing this all the time. I prefer a mirror that has a ball mount, but then locks down with a locking bolt - that way it is always in the right spot. I use the R50 by Spurcycle and find it to be excellent for this reason. Once positioned it is very secure, even over rough terrain (which other mirrors struggle with). "
"The bicycle company Pole (Finland-based) utilized this approach first. Their approach is a bit more interesting, in my opinion. On their "Stamina" series, they glue the two halves together, instead of welding them. "
