Your rim diameter limits your tire width options. If you ride over sand often and your bike frame supports it, consider switching to a wider tire. Using wide tires impairs performance on hard surfaces. If you’re riding a trail with mixed conditions, you’ll have to compromise.
If you have a fat bike, you can go as low as 4-6 psi. For a mountain bike, lower the psi to 18-20. [3] X Research source
You may shift when traveling down a sandy slope, since you’ll have enough speed to carry you. Make sure you’re in a gear for easy pedaling once you hit flat ground.
Steep slopes are especially difficult. Stay away from them until you’re more comfortable. If cycling at the beach, stay near the water but out of water range. You’ll have more room to maneuver at low tide.
While riding on dunes, you can even pull up a little on the handlebars.
Ride slower than you normally would, especially as a beginner. It’s easy to lose control over sand, and you don’t want to go flying over the handlebars. If you’re on hard ground and see a small patch of sand coming up, gathering speed may help you pass through it. Don’t forget to take your weight off the front wheel as you approach.
If you quickly turn your tire, it will dig into the sand. [8] X Research source
