R Martin E-Bike Battery Cell Replacement Service

We can rebuild and upgrade the R Martin E-bike batteries with the integrated rear rack. If your battery is losing power and not giving you as much range as it once was, let us take care of it and get it running better than new!

We can replace all of the cells inside with brand new, state of the art lithium ion 18650's. This can upgrade your capacity, increasing your range and ride time over the original specification. We can take care of the rear rack mounted battery, upgrading it to at least 36V 14Ah.

All of our rebuilds are backed by our 1 year warranty. Don't let a dead battery keep you off your wheels, contact us today!R Martin E-Bike Battery
