What people are saying about us...
I love my UltraCool Cooler. My wife and I rode about 10,000 miles last year and it really performed great. We go to Myrtle Beach Bike Week every spring and fall. The hot weather in May was flawless and my bike ran cooler!
Longer rides on vacations, this bike and I have been across this country several times. On my commute to work and back oil temperature averages right around 215°F. That’s after 30 minutes of city traffic! Amazing!
Even in the extreme heat of the Valley my cooler never lets it get over 230 degrees. Very happy with your product and the installation was very easy. Would strongly suggest this cooler for anybody in hot conditions!
