Normal beginner's fatigue or dodgy bike?

Another tip for beginners is to make sure you have enough air in your tires. Flat tires make for really hard riding. Believe me, I learned the hard way.

I saw that you have front suspension & trouble steering - I'd try turning it off & seeing if that helps.

Your fatigue could be low carb and beginner's fatigue. Try having a bowl of oatmeal or other slow digesting carb before you go out & see how you do. I've ridden on empty and fueled & I much prefer fueled. Studies are saying that weight loss happens better when you are fueled because you can go harder & longer. I also believe that it makes riding more enjoyable = you'll do it more often.

+1 on the air. And is there another bike shop in your region? The one you went to is beyond bad.

Changing subjects when you ask questions refusing a test ride and then saying you can bring it back for a fit in 8 weeks??? 8 weeks??

If I bought a bike or had work done in any of my favorite shops and had issues I could bring it in or at least get an appointment for them to take a look that day.

You might end up loving the bike but find another shop.

Also if you feel twitchy on the bike relax, d@mn it!! especially your hands and arms. Having a death grip actually makes it harder to control your bike.

So a few things that I want to echo here. Pretty much all of them have already been said but I ould say they are really key.

1) Air up your tires before every ride.
2) Lock out your front suspension for now
3) You should be eating a good meal about 4 to 5 hours before you ride and take another hit of about 100 calories a half hour to 45 min before you ride. You want that last hit in an easily digestible form like energy chews or gels.
4) After you finish riding, take in about 180 to 200 calories within 20 min of being done. Ideally you're shooting for about 30 g of carbs and 10 grams of protein - reduced fat chocolate milk is great for this. What this does is store glycogen in your muscles where it will be readily available as fuel for your next ride, making you recover faster. Then you can go low carb the rest of the day and let your heightened metabolic activity burn off the fat.

About the low carb/blood sugar thing. Like someone else mentioned, you don't necessarily get hunger when your blood sugar drops. When I am mountain biking, I almost never want to eat. But I know when I have to because I start falling on technical things that I would normally be able to do no problem. My coordination gets very sketchy. So it could very well be part of your problem.
