That's 13 sets for legs. Once a week for that amount of volume is certainly doable.

If you can, though, I'd split the squats and DLs up into different days. You'd probably be fresher this way for the DLs and perform better on them.

Also, if you can, maybe move your bike workout to another day. It's not necessarily terrible doing them after your leg day, but it could slightly compromise gains. In order of preference:

• cardio on a completely separate day from weights
• cardio at least 4 hours after training
• cardio immediately after training
• cardio immediately before training (this is the worst option - but note that your 10 min of warmup cardio is just fine if it's not super strenuous)

Since you are starting with the cardio I'd increase that by 5 to 10 mins, then drop the biking at the end replacing it with some dumbbell lunges and calve raises. Also leg press and squats work very similar muscles, so you might want to change one of those for another leg exercise or core exercise.

I don't think it's too much. I don't really consider deadlifts that much of a leg and instead a back exercise. I also go 1 rep max on deadlifts, where my 2nd to last set is nearly max and last rep is max.

I'd recommend doing romanian deadlifts instead of leg curls or leg press. I added them in the past year and really feel them. I do them elevated so i can really get low with barbell.

I would consider reducing squat rep count, but it also depends on your goals. I recommend against doing a "if its available" mentality, as it made me often skip. But the other person had a good point, probably shouldn't press and squat
