It’s fine if you check frequently for cracks. It will break with enough miles.

Suspension helps reduce frame damage. Coil shock up front with a seat shock of some kind.

The black bike in my avatar is aluminum, its my first bike I built in early 2011.
Greg over the years I've pounded aluminum mountain bike frames no suspension and with partial or full and they held up great just as good as steel.

I prefer to work with steel however, but still use aluminum frames on some of my motorized bikes; my Grubee is a 2011 frame as well and is coming up on 20,000 real world miles with not a crack & half of that with no suspension on seat or forks.

Done a few with Alum. Frames. No Probs. Mount the motor secure being careful not to crush or distort the alum. My Daily is an Alum. Genesis Onyx 29". Very solid.

Allen the Genesis is a good example, along with Felt, Fito... and a host of others that are excellent choices to motorize and ride hard daily on the street.

I prefer to work with steel only. I have the mindset of failure aversion: a steel frame will give warning before complete failure. An aluminum frame will simply fail.
