Super Segway Mod
This is probably not a very safe thing to try for yourself, but some guy modified a Segway by replacing its original wheels with a set of larger wheels and turned it into a super Segway!
This single modfication was enough to make the Segway capable of reaching a top speed of 25 mph which is a little too speedy for a personal transportation vehicle like this. While the original one can be considered rather safe when used within its limits, this one certainly rings alarms everywhere.

Just thinking about the chance of the wheels locking while travelling at full speed simply scares me. That’ll surely turn into a painful encounter.
