My answer as I'm currently. Battling. A ever + present rear flat tire is I have a bike mount hitch on my van and I'm leaving it there. My key for my van stays in it as the door key is a different key altogether. I'm only 6 miles from. My PT job but 13 miles one way from my. Full time job. Kinda out in the woods ish. So my back door is unlocked and if people make it past my dogs they can get a door key. Get my van and help me, usually because I've called them asked them to locate the key and bring the van, I load the bike to the bicycle rack and drive home but it's typically my fiance who rescues me so I don't have any experience on the roadside I find myself slowly walking in the direction of home pushing the bike and looking defeated.
I got the bike motorized so I can save up cash to replace the motor in my car. I let me fiences drive the van or keep it parked to save on gas and keep its miles low... and walking home. Knowing I'm running the van just makes me sad.
I have looked into spare tubes and. Quick fill CO2 cartridges but I don't think it's safe to load a already heavy motorized bike with wrenches, spares patches and ect. I am a bit concerned about over weighting my bikes
