So..I set off this am for a bike ride with the Propella. It looked like rain, so at the last minute, I changed my shoes to an older pair of lace-ups.
I must have had the lace bows too large because my right foot lace got caught in the crank/chain and threw it off.
I had it almost back on with one hand holding the chain near the teeth and the other hand to turn the crank. (the shoulder was grassy...so the tire could slip)
As the teeth grabbed the first couple links, I started to turn the crank and the chain took off like a gas chain saw!
Dang it...I forgot to power down the assist.
Luckily, (and I don't know how) I managed to jerk my hand back before my fingers went between the sprocket and the chain.
Prob wouldn't have broken any fingers, but I'm sure there would be some torn skin.
Stupid mistake....live and learn.
