| Vehicle | 2009 Electric Motorsport GPR-S Street legal bike up to ~70 mph with 15-tooth sprocket. Fun bike that's easy to ride. The original configuration was with SLA cells. Range was too short so I upgraded to LFPs. It's much more useful now. One of the great features of the GPR-S is its modularity and flexibility. Few other bikes even have the option to upgrade to a completely different battery chemistry. | ||||||||
