I had seen this before but today got into the detail a bit and several ideas came to mind.
1. this is safer than my trailer on the open road because it is the width of the bike with panniers
2. easier to navigate some of the cycle paths I use than my trailer
3. as one of my panniers is already filled by my BFBattery one of these would allow me to bring three panniers of shopping home instead of one
4. a good idea for people with an e-MTB and no rack
5. your idea goes here...
