HOUGHTON -- From flat tires to rusty cables, the mechanics at Downwind Sports see it all.  With the first signs of spring, they get dozens of owners bringing their bikes in for a tune-up, which averages $30-$60. 

"I’ll call back with an estimate if some parts are needed, but mostly it's just some adjustments and cleaning,” says mechanic Dan Wissman.  “We can also give an idea of turnaround time, which is usually a day or two."

But if your bike is beyond repair or you're looking to try something new, there are a variety of mountain bikes and road bikes to choose from.  Prices range from several hundred to a couple thousand dollars.

"With a road bike, the body position is hunched over and the tires are a little skinnier, which makes it more aerodynamic,” says salesman Greg Maino.  “A mountain bike is going to have a fatter tire with more knobs.  It's also more upright positioning, which allows you to move around a little bit better."

In addition to a good helmet, you might consider other accessories like a lightweight jacket, biking gloves, or a hydration pack that allows easy access to up to 100 ounces of water.

"A water bottle can fall out or sometimes it's hard to get at, so you don't drink as often,” Maino says.  “With a hydration pack, the water's always available, so you can drink more often.  They're also nice for keeping spare change, a jacket, or extra food."

If you only ride on occasion and aren't ready to commit, it might be best to use a rental.  Most shops provide mountain bikes and helmets at an hourly or daily rate.
