This week, I watched a documentary about some adventure motorbike riders. They were confronted by trees blown down across their path…but had no chainsaws with which to fix the obstructions.
Today’s invention is a set of sharp teeth which can be fitted through a motorcycle chain. Each tooth is retained using a circular spring clip, that stays out of the way of sprockets.
If you get stopped by a large branch, first place the bike on its centre stand.
Fit say thirty teeth to the chain. Push the chain into contact with the wood, engage first gear and open the throttle.
