1. The most important thing about buying a new bike is to make sure it fits. The only way you'll know if the bike is right for you is to size up the bike and make sure that the bike's geometry matches your body's geometry. Ask questions and do some research.

2. If possible, try to find a shop that will let you demo the bike on real dirt. Five minutes in a parking lot won't cut it. You wouldn't buy a car without a real world test drive, and a bike should be no different.
3. Don't belive the hype. Just because your favorite rider or best friend rides a certain bike, that doesn't mean that's the best one for you. Have an open mind and be realistic about your needs and ability.

    Presta threaded end pump frustrations

    I'm fine with pumping my presta valve tires with a floor pump with the switch that connects and disconnects from the valve.

    I bought a Lezene portable pump that screws onto the presta valve.

    What happens is I loosen the presta valve, then thread the portable pump hose onto it and pump. When I unthread the hose the whole valve core comes out with the pump hose?

    Is the solution to not thread the portable hose snuggly to the presta valve?

    Thanks
    Bill

    I would tighten the valve core, and only thread the hose on as far as needed to fill with air. I have a Lezene floor pump with the same screw type fill valve, and had this happen once. I simply used two pairs of pliers, one to hold the valve base and one to tighten the core. I haven't had an issue since.

    Good luck!

    I also have a Lezyne floor pump. I addition to the suggestions already made (esp tightening the core), try putting a very light coat of grease or lube of some sort on the valve threads and/or the inside of the hose head to ease removal.
    Use it, use it, use it while you still have it.

    I have a Lezyne portable screw on pump. This hasn't happened to me. I agree with tightening the core.
