Well, the beauty above isn't quite mine yet, but I hope it soon will be. I'm working with an electric scooter vendor in San Diego to configure the above emoped to my needs, and I could use some advice from the forum. Currently this bike has a big heavy 60V 12AH silicon battery that goes about 28 miles between charges and a 450W rear hub motor that gets it up to 20 mph. That's not quite good enough for me to be able to ride with my local moped gang, whose gas mopeds average 25-35 mph on rides up to 40 miles in length.
Sooooo, my simple goal is to configure the emoped so it can go at least 30 mph, preferably 35 mph, for a range of up to 40 miles between charges, preferably 60 miles (so I can drive it to work and back 12 miles every day for a week without recharging it).
My vendor and I are sorting through ideas to make this happen, and so far are thinking of:
-- switching out the heavy silicon battery pack for lighter, dual lithium long-range battery packs. I already own one such battery (52V BYI Super Lithium Polymer, 10 amp hour with 35 amp gateway & 25 amp hi-power BMS, Soft Pack technology) so I may just need to get one more.
-- adding solar panels for incremental charging along the route and while stopping for breaks
-- more powerful rear hub motor
-- more robust controller to handle the bigger motor
If anyone has more specific tactics to help the emoped reach 30-35mph for 40-60 miles between charges, let me know, along with how much extra you think it'd cost. I appreciate it!
