Cruiser - The name says it all. If you are looking to cruise around town then this is the right complete skateboard for you. These decks vary in length from between 20 inches all the way up to about 40 inches. The wheel diameters usually start at about 55 millimeters and use a much softer urethane than the previous Popsicle decks. These also come with all of the above but the decks do not always need grip tape. Some of the decks are plastic or composite material with grooves or gripping built directly into the deck mold. 

There are actually several types of skateboards but the most common ones are the longboard, cruiser, and carve skateboards. A longboard is usually at least 33 inches. It is a great mode of transportation and works well for cruising around. The cruiser also works well as a mode of transportation but many consider it more beneficial as it has a shorter skateboard, which promotes ease in transporting around.

Do your Ollie, then, instantly after you pop your board, lift your back foot up to meet your front foot. That helped me solo much I improved twice in a few tries with using that trick. And, if that doesn’t help, it’s just a matter of practicing. If you practice a ly every day, you experiment, you will find u r solution. But, try lifting u r back foot high right after u pop 😉
This can be tricky to figure out, so just take your time and relax. The first few times you try and ollie, it helps to not worry about this part. You will end up doing a sort of half-ollie, popping just a little in the air. Or, you might fall! But, don't worry, this is all part of learning. If you want though, you can certainly start with rolling your ankle when you try and ollie - whatever works for you! Eventually, you will need to roll and drag, and you'll figure it out. Just take your time!
To get higher ollies, I would suggesting resting your back foot on the very end of the tail and the front foot in the middle of the deck to allow for more slide. Popping as hard as you can and catching your board in the groove of the nose with you ankle practically resting in the groove will level the board out in the air. after this initial movement slide you feet back to the bolts on the tail and nose to ensure a clean landing.
