Got Questions?

Frequently Asked Questions

Do you offer mobile repairs?

Absolutely. We come to your location with all the tools and parts needed to diagnose and fix your ride on-site — whether you’re at home, work, or out on a property.

What types of vehicles do you work on?

We specialize in:

• ATVs

• Dirt bikes

• Motorcycles (street & dual-sport)

• Side-by-sides

• Generators

• Small engine equipment (mowers, snow blowers, etc.)

If it has a small engine, chances are we can fix it — just ask.

How quickly can you service me?

In most cases, we can book you for same-day or next-day service depending on your location and availability. If it’s urgent, reach out directly — we’ll do our best to make it happen fast.

What payment methods do you accept?

We accept:

• Cash

• Debit/Credit

• Venmo

• Zelle

• Visa
• Master Card

Payment is due after service is completed unless otherwise discussed.

Is there any kind of warranty?

Yes — we stand behind our work with a 30-day workmanship guarantee. If something we fixed isn’t right, we’ll make it right — no hassle, no fine print.

What if I’m not home when you arrive?

No problem. If you can leave the vehicle accessible (e.g. driveway, garage), we can complete the service and send you updates and a secure payment link. We make it easy for busy riders.

Built for Off-Road Power

We’re dedicated to keeping your machines trail-ready with high-quality repairs and fast turnaround. Whether it’s a weekend ride, a workhorse ATV, or a custom build — we treat every vehicle like our own. Based in Flagstaff, proudly serving surrounding areas.
