I know I do some stuff that could be considered un-safe if done by an untrained individual, so even looking at what I am talking about here should be considered dangerous – but I am fascinated by the unicycle world right now and found a “two speed unicycle hub”. Unicycles – by definition – are fixed wheel. You pedal, it goes! Well… with this hub, you can go FASTER! I cant use it yet – cuz well – I can’t go. The hub has a warning:=
Warning: Geared hubs can be dangerous due to the high potential speed and the risk of unplanned dismounts during shifting. Ride within your limits!
Thankfully, the product warning has saved me from a bad situation! I feel safer already!
