I've once again been looking around at electric transportation, and the XM-5000Li struck me as close to something I'd like, but just a bit lacking in some ways. Is it possible/feasible to mod the bike to do 70-75 with a 275 pound rider and about 60 pounds of cargo on California bridges/freeways (Golden Gate bridge, I-880, etc.)? I see in the demo video on the x-treme site that it only managed 64.7 MPH with a 150 pound rider.
Also, I see talk of how a BMS (battery management system) is good and yet not good in all cases. What are the upsides and downsides of having BMS on the batteries on an electric motorcycle?
Also, can the controller on the XM-5000Li be programmed? On my power wheelchair, a handheld programmer can be used to change the forward acceleration and about 10 other settings. I'd like it to accelerate faster than was shown in the demo video on x-treme's site, as 15 seconds to get up to 60 could be dangerous on some roads. Perhaps 10 seconds to get to 60 would be safer.
Also, do bikes of this level generally come with regenerative braking, or is that generally an aftermarket addon?
Also - What are some available/popular mods for this bike? I could see it and the rider benefiting from a much larger windscreen, and even at stock settings, it managed to more than peg its speedometer. I'd like a better speedo (digital?) on it.
Lastly, if this is just too much to ask out of this bike, what are some of my other options?
