BionX E-Bike Battery Replacement

AS OF AUGUST 2020, WE ARE NO LONGER REBUILDING BIONX BATTERIES DUE TO A HIGH NUMBER OF FAILURES OF THEIR BATTERY MANAGEMENT SYSTEM BOARDS WHICH WE CANNOT REPLACE. WE RECOMMEND CONTACTING OHM CYCLES OR BIONX LEGACY SHOP.

Do you have a BionX e-bike that needs a new battery? Let us rebuild, refurbish, and upgrade your old one! We can swap in fresh, grade A lithium ion cells to get you back on your wheels. We've squeezed in as much as 40V 13Ah in a rear rack case more than doubling the range of the original battery. We can take care of all form factors of BionX e-bike batteries whether it's the rear rack or down tube style.

Some of these larger downtube, triangular, fin-shaped batteries can hold up to 60 cells, giving them plenty of room to be upgraded to 36V 21Ah.

All of our batteries are warrantied for a full 12 months. All you need to do is fill out our Battery Intake Form and send us the battery, charger, and bike. We'll even recycle your old batteries for you! Don't let a drained battery keep your bike just collecting dust. Give us a call and it'll be going better than new!

BionX E-bike Battery Repair and Upgrade

Due to the nature of the BionX systems, we require the bike in order to validate the rebuild.

    When I plug my charger to the bronx battery, it will flash for a nanosecond & goes blank. The battery will not charge. Any suggestions?

    @Peter – Unfortunately, we are no longer doing BionX rebuilds. We’ll be in touch with our recommendations though.

    Are you able to re-cell my Bion X battery? it’s Li-Mi 26v and looks like the third illustration. It’s not accepting charge but the control console does light briefly.

    @Lance – We’ll be in touch with our recommendations!

    I have a 2009 Trek T500 E bike with a BionX battery, barcode: 2145-S08347742. It is a rear rack battery. Please advise estimate for replacing battery and separately the cost of a new charger. Thank you.
