BionX E-Bike Battery Replacement

Posted on July 24 2017

BionX rear rack battery replacement

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.

    @Les – We are not currently rebuilding BionX batteries at this time. We’ll be in touch with more info.

    I have a 7 year old Trek bike and the Bionx battery (rear rack style) is faulty.
    I believe that you require the bike when repairing batteries – is this correct? A couple of further questions.
    How much would you charge and is the work guaranteed? I live in Edinburgh.

    Look forward to hearing from you.

    @Tom – It sounds like your battery is dead. We’ll be in touch with our recommendations.

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

  • EBike Marketplace: July 20, 2020

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

  • Peter Thomas: July 20, 2020

    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.

    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.

  • Thomas : July 07, 2020

    would I be able to use my existing charger!?

  • Lisa Rusciolelli: July 07, 2020

    I’m searching for someone to either rebuild my rear rack Bion-x system or convert to a Bosch system. Please contact me with further information about where you are located.
    I understand why you need the bike, but shipping it may make this endeavor cost-prohibitive.
    Thank you!

    I have a Bronx battery that is dead. Can you give me a email to get more info regarding the repair?
