TranzX Battery Cell Replacement Service

TranzX is a company that makes parts for a number of e-bike manufacturers, including batteries. When the battery dies though, replacements can be tough to come by. That's why we offer our rebuild service! Send in your battery, we replace all of the cells while re-using your case (so it's guaranteed to fit back in your bike), and send it back to you! Often, we can upgrade the capacity to give you longer ride time as well!

TranzX BL17

Here's the popular TranzX BL17 model battery that's used on iZip E3 Dash, E3 Peak, and E3 Sumo model bikes, along with the Raleigh Tekoa, Route, and Misceo, among others. It fits on the downtube. We can upgrade these from 417 Wh to 504 Wh with our 10.5 Ah rebuild.

Raleigh Sprite Battery

This is the TranzX BL07, a rear rack model, that Raleigh used on some of their electric bikes like the Retroglide, Superbe, and Sprint. We can also upgrade these up to 14 Ah using our rebuild service.

    I have a 2015 Reliegh Takoa iE with the tranzX BL 17 battery. The battery is recently not lasting as long as it once did. How much would it cost to have it rebuilt? Upgrade cost?
