(see update on adjuster below)
I saw those expensive wheelie bars motorcycles and thought "Hey I can make one of those!". And I will show you how!
Note on the little axil plate I meant to say 3mm X 5cm X 10cm.
Also as you watch me wheelie, I probably need to adjust the bar down more closer to the balance point.
Another note, instead of using the temporary bungie chord the "stopper" can simply be fixed down to the swing arm with a hose clamp or something.
Have fun!
I added an adjuster to the "stop bar" that hits the swing arm. At the end of it I drilled a hole and threaded it and put in a rubber bumper on a bolt that can be adjusted up or down to move the wheelie bar up or down.
