E-bikes in a row have become a familiar sight in many cities in Australia and around the world. The bikes are usually powered by a lithium ion battery and these have been known to explode (see video below).
Explosions are caused when a thermal runaway operating on the battery is triggered. Anyone interested in turning an e-bike into a stationary or moving improvised explosive device has only to construct an appropriate triggering mechanism.
E-bikes are often arranged in arrays such as that above, somewhat like a shopfront, and that proximity could possibly be utilised to multiply the impact of an explosion, by using a single or multiple triggering devices.
The threat to the public at large from e-bikes and bike sharing schemes in general has been ignored if not derided .
