lidl tank bag question.

i got one of those 14.99 thingys, it sits on the tank nice but slides around without the strap fitted, the tank bag comes with various straps x 3 and can be worn as a rucsak, my question is can it be used as a tail pack aswell? it seems to fit the tail better than it does the tank because i can get one of the straps round the tail to hold it down. it seems a good piece of kit for the money.

You could use it as a tailpack, just put the tank strap under the seat instead and adjust as needed. That's not enough though, you should have bungees or a cargo net over the top of it.

yea think i'll put a bungee net over the top just incase.
