Hi!, there are 3 main things when replacing a rear hub tire tube.
1- hub cabling: as the motor cable comes out from inside the hub, some handling will be involved on the repair
2- You need a specific way to secure this wheel to the frame. Specially because of the excess forces that are at play. So you need to go through a couple more steps than a normal bike
3-tools: there might be a bit more tools that you need to carry in order to do a full replacement. Sometimes this is why lots of riders prefer "Get Home kits"
We are working on tutorial videos so anyone can see how we do it. With the practice we have ( and the proper tools) you can do it in a couple of minutes
What is a "get home kit"? Probably you mean these extra tools you need but exactly what are they?
2 minute exchange, with much practice, is very encouraging. I imagine that is in a shop with stands, lifts, whatever, but still very good. Not that we're counting minutes here but since you bring it up, about how long, with all your practice, would it take you to do solely with transported tools on the side of road?
Hope you get the YT vid up soon. Thinking I'd better see it before purchase
