I find myself getting out more often with Sam and we both get great exercise. I love the fact that I can pack his and my stuff on my rack!

Our group rides have definitely changed since I got my QuietKat Warrior. It's become much easier as an "older dude" to keep up with the youngsters out in the woods! Loving my e-mtb!

Jay F.

I love doing a 12 mile bike loop around our lake every weekend, but it was starting to be a bit much for my knees & back to handle. The electric assist on my e-bike has been a god send! Thank you so much for making my favorite weekly activity possible & enjoyable again!!
