Today I rode for the first time after reprogramming the controller in my scooter. I had lowered the maximum power from 80% to 70% and reduced the maximum speed as well. Making the change was relatively easy once I properly configured my windows xp installation running on Parallels on my Macbook Pro. The application itself was a free download.
Most important, was testing the range, the issue which has been most difficult for me. I’ve previously attempted a 16 mile round trip only to complete the last couple of miles in “limp mode” when the maximum speed is only a few miles an hour. This time I fared much better, riding 22 miles before I limped the last few feet home. Twenty miles is enough for pretty much any ride I would undertake without having the opportunity to charge in the middle. i can now easily visit friends in Alameda without a problem, though the furthest points of Richmond might be pushing my luck, especially if steep hills are involved. For those who may be reading this and who are located in a less hilly region than Northern California, note that I had some serious hill climbing in these 22 miles. The most noteworthy was the steep climb up Pleasant Valley Road from Broadway up to Piedmont Avenue. In a less hilly region, it might be possible to squeeze a few extra miles. When time allows, I may try a flatter ride to see what difference it makes. In the meantime I’m grateful to have the extra range.
But how much did I give up in terms of power? My maximum speed at 80% power was 50mph which I only hit a couple of times. 45mph was a more realistic max. Now that has been reduced by 10mph to just 35. Fast enough to maintain the legal urban speed limit, but occasionally a bit slow to keep up with traffic. It’s a compromise for sure and I can always tweak the power setting a bit to 73 or 75% if I decide its necessary.
