Saved my life

I was skimming the bleeding edge of the Grand Canyon at 35mph in pitch black on my fat tire ebike that has a ROCKIN 🤟🏻 battery in it. The battery was so ROCKIN🤟🏻 that it overheated and exploded sending me to certain doom had it not been for my Topeak MTXFD4567 whatever it’s called. After being high sided and effing launched 🚀 ten feet through the crisp midnight air I simply twisted my body (leading with my head every gymnast knows that) and while in a straight bodied somersault reached out and grabbed the water bottle bit thing on my topeakMdS13th which held true, while my lucky front tire got caught on a helpful tree trunk as I hung over the edge pretty much 32,000 feet above sea level. The dead zone. With rock climbing experience under my belt I used my right forefinger, the only thing holding onto the water bottle bit thing, and launched myself and my fat tire super rockin ebike back to safety.

Thankyou TopeakMDXGJKKEUU186636 for saving my life.

The pic is exactly how I held on with only my forefinger.

A super grateful Dan.
