FLX Flux Battery | Rebuild Service
Is your FLX e-bike battery losing range or no longer charging like it used to? Instead of replacing your entire bike, restore your battery’s performance with our FLX Flux Battery Rebuild Service. We replace the old, worn-out cells inside your existing battery case with brand-new, high-quality lithium-ion cells, bringing it back to life and often improving its capacity.
This service saves you money, reduces waste, and keeps your bike on the road.
