Those things are pretty strong, they don't just break when falling over. Chances are the cyclist would still lose. Better replace it with a landmine, or something else that really explodes when getting hit.

Ok but I don't think propane tanks are as fragile & explosive as they suppose.

Pressure relief valve needs to be sealed so it can really go boom.

I always loved in Snowcrash the key antagonist drove around on a motorbike with a side car with a ex-soviet nuke wired to a heart beat monitor. Security companies spent their time not trying to stop him but trying to stop his numerous enemies from trying to kill him

Sure its going to be a bit of a fizzle when the tritium decays but still gonna make one hell of a hole in the road if someone dares to hit him.

M.A.D.D. isn't just for insane world leaders anymore!

Like that dude in Snow Crash who has a niclear bomb for a motocycle sidecar.

The alahu akhbicycle.

I see your car. Do you sea-mine?

I Die You Die

When I see this thumbnail, I think about the Korn album Follow The Leader.

It's a nice thought but people still drive like assholes around full blown tanker trucks.

In my experince this sort of thing will work better if the propane tank is clearly visible.
