The best system back
This thing saved my life! It is supposed I can’t bike any longer because I had a surgery on my back and it’s dangerous but well, I take the risk, I practice MTB and unfortunately, I fell down on my back last week I was scared but I couldn’t believe it, I didn’t feel anything, the VPS system was activated and I didn’t get any injury. I just have a question, my VPD system is fine, does it still work?
