Such a beautiful day - I just had to see if I could make it up into the mountains to Golden Gate Canyon State Park from W. Arvada, CO (5600' up to 8600' elev.). (Astar, this report is for you; I'll be waiting to hear about your trips up into the mountains on your 7100; a 3000' elev climb probably will be lost on the flat-landers).
Last week, I had taken a partial trip and armed with a topo map/GPS/CA, I determined that I consumed 120WH/mile while actually climbing the mountain. It is amazing how much juice inclines take out of your battery pack; normally, the 6100 maxi-scooter takes 65-70WH/mile in city riding. So, I did my calculations and figured I could make a go for it without having to recharge. Keep in mind, the bike only has 40AH (unlike the ZEV Trail bikes with 60AH).
I was tempted to top-off the battery before heading out, but I was in a hurry to get going and it had been charged within last 2 days (LiFeMPo4 cells hold their charge very well). So, I just threw the charger under the seat in case I was wrong with my calculations and thought the park would have an outlet if needed.
6.5 miles of city/hwy riding to get to the mountain hwy 46 turn-off, 12.3 miles of mountain climbing to the park. Beautiful ride; nice sharp twisty turns; highly recommended. Cheap rangers at the park; when I asked about opportunity charging at the park, their answer was - they would be happy to arrest me if I tried! They did mention there were RV camp sites with electricity for the bargain price of $22/day. I chose to take the risk and not recharge.
Trip details: 70.2 WH/mile, 37.5 miles, 3000' elev change, 36.9AH, 58.3mph max, 31.8mph avg, beautiful ride and a hole lot of fun on a twisty mountain road. This was cutting it close on the pack level, and next time I will top-up the pack before heading out to increase pack margin / voltage level.
