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.

    Where can I get a Bionx 36v replacement battery and charger?

    I have a Bionix Bike, battery is dead. At this point, I am not sure if I should bother to have the battery rebuilt, or get a new bike. I had the battery rebuilt once, Now I suspect that charger MAY have a problem.
    I really don’t want to buy another bike, I spent lots for this one.
    Any suggestions?

    @Linda – We do not stock new/replacement OHM/BionX batteries, but we can rebuild yours if the circuit board is still operational.

    I own a BionX XU700LX bike. The OHM battery fell off our counter and now I am having difficulties charging and mounting it on the bike. The battery is an old model-long rectangular in shape and is rear mounted. It is about 3 1/2 inches tall. 15 1/2 inches long and 5 3/4 inches wide. It has a flashing light at the rear of the battery. I haven’t seen one in your pictures on your site.

    Is it possible to get a replacement?

    Thank you for any help you can provide!
