I think they are too tall for the wheelbase. The design is narrower than traditional auto-rickshaws. I think one of the issues is I think that the battery is not heavy enough to stabilize the center of gravity once you start tipping over - instead of stabilizing, it probably makes it tip over faster.

I am not talking about crash testing or anything that sophisticated. Something as basic as the tendency to overturn is much higher. I have seen one happen right beside me, when one of the wheels went into a pothole, and the rickshaw tilted and overturned. A traditional auto (the standard Bajaj model ICE, for example) would have "jumped", but not overturned.

On this same note, the Bajaj ICE is slightly narrower at the top than the base, in a tapered design - this will increase stability.

Piaggio Ape is tapered towards the top and has backwheels turned inwards -

e-rickshaws show none of these features.
