Selling my genuine Bosch PowerTube 800 (800Wh) battery that came on my 2025 Trek Rail+ (Montrager RR). I purchased a second battery for my White Rim Trail trip, so I no longer need this one.

The battery has approximately 700 miles on it and has been flawless. It has always been well cared for, stored indoors, and never crashed or damaged.

Bosch Flow App Verified:

Approximately 700 miles of use

Only 20 completed charging cycles

Fully functional and holds a charge perfectly.

This battery retails for around $1,300+ before tax, so this is a great way to save several hundred dollars while getting a lightly used OEM battery.

If you’re not sure whether it’ll fit your bike, send me your bike’s make/model/year and I’ll help verify compatibility.

Local pickup preferred, but I’m willing to ship at the buyer’s expense.
