Hmm can a trike slide backwards on gravel slopes?

Depends on the slope, I guess. Something I found out on my first
tadpole (S&B) with a motor- on gravel I could break traction, hit the
Currie motor full throttle, turn hard right or hard left, pedal like
crazy and do little donuts!

Not answering your question, but trikes can slide!!!

(I am so glad that I am over 50; so I can blame my foolish riding on
my 2nd childhood)
