I think the front hub idea could work, but I’d want to keep the towed bike as low as possible to help with balance. It’s got a much higher center of gravity with this setup.

Alignment should help though.

I towed my son around on one of these when he was younger and it could be wobbly even though it was perfectly aligned. At least when he wasn’t paying attention to his balance too!

    They scattered infrared light in a weird way.

    I was actually installing a system with passive IR motion sensors that worked great at night, but as soon a as the sun was shining in, went all haywire. We brought them down the hall to the older tinted window wing, and they behaved normally again. They even worked well outside, which we thought was the worst case scenario during testing.

    When we came back with an ir camera, it was full of scattered noise, but the resolution wasn’t good enough to understand exactly what was happening and we had already switched to different hardware that worked around the problem.

    That makes sense. I wonder if it measures the torque input requirements vs output, or is it just measuring the maximum speed the motor will spin.

    We used to regularly break the speed limit (35mph) going down hills in my neighborhood on our 1980s 10-speeds.
