180 miles to the charge. That's a lot! WOW!
Wouldn't it be great if a manufacturer made a fuel-cell engine that attaches to ANY bike? Potentially, ANY bike could run on these rechargeable fuel-cells. That way, you could trade in an expired fuel-cell with cash at the local convenience store for a fully-charged fuel-cell. Same way we do with propane tanks today. Since all diamond-frame bikes are made with nearly-identical frames, and all are driven by metal chains, I think this idea could be made to work.
