More students = Less battery?

Well a new semester at UF has started. This is always bitter sweet for people who live in Gainesville. It means that the roads are once again crowded with students. And the buses. It’s a good thing, if you like being stuffed into public transport with young college girls. And it’s great from the point of view of skateboarding past a long line of traffic. But it’s bad in almost every other aspect. Oftentimes now, the bus is so crowded that I can’t get a seat. People bump into my board when they walk past me. And worse, there’s more foot traffic on the sidewalks I’m forced to skate on. Which means more slowing down. More yelling “Excuse me,” (I’m still waiting for my electric horn, kickstarter), and statistically, I’d expect to have more collisions with pedestrians.
When I ride the bus, I always try to stay at the front of the bus. This is for practical reasons only. I get off at a stop on the top of a small hill. If students get out in front of me, I’m just going to have to pass them, half a moment later. Since I’m consistently the only skater getting off at that stop, if I get off first, I can blow down the hill without the inconvenience of passing someone who may or may not suddenly decide to step in my way.
I’ve been boarding home long enough to have learned to take a shortcut through a parking lot. To simply take the bike line down one, off campus street, where the UPD has no jurisdiction. But by the time I get home, about four miles ride in total, I’ve been getting the low battery light.
This troubles me slightly. Remember, I keep meticulous logs on how often I skate, and the distance I skate when I do. The purpose is to show what kind of mileage my board can get. This is dependant on many factors. Florida is known for being flat, but my route takes over several hills. And with the students in town, I’m doing a lot more braking and accelerating. So that factors in.
According to my log, I’ve traveled 669 miles on my board so far. That’s no small chunk of change. I’ve changed the grip tape once. The wheels show no signs of wear. But if the board blew up tomorrow, it would have cost me about $2 a mile. Of course, I’d expect it to last longer. Much longer. At the one year mark, I’d expect the cost per mile to go down to less than $1 per mile. How cheap a form of transportation it is depends entirely on how long the battery works for me. But if my four mile commute becomes too much for the battery before then, it will be a bad omen. I’m hoping to ride the board long enough to get the cost down to at least .50 cents a mile. But only time will tell.
In other news, @evoskate44 followed me on twitter. They’re the European branch of Evolve, not to be confused with @Evolvesk8boards. Either way, yay! I’m almost mildly relevant in an emerging technology most people don’t know about.

Best on Block / Boosted Response / Carbon Series

Driving home with my girlfriend, we saw the neighborhood kids, out on their scooters.
“I feel really bad about showing off my skateboard to them,” I told her. “We live in the ghetto, they can’t afford one. It just doesn’t feel right. It’s not the same as when I do it in the rich neighborhoods by the beach.”
When we got out of the car a minute later, I heard something new. The sound of a small electric motor. The poor kids had new scooters. Electric scooters.
“Oh hell no,” I said. “It is *on* now. If they can afford electric, then they can afford to know that I have the best one in the neighborhood.” I said. I went inside, got my Evolve longboard, and skated around them.
I went at their pace for the first block. I asked them what kind of scooter they had, but either they didn’t know or were apprehensive about speaking to a ‘stranger’ or both. “Wanna race?” I asked. They nodded and sped off. I gave them a headstart, and they blew past them. I lapped them. I peeled off around a corner, and disappeared into my house. Hopefully, the illusion fooled them, and they thought I was gone, already the next neighborhood over.


In other news, Boosted has responded to me about how they come to say they’ve got a six mile battery on their board. I’ll let him tell you:


Range estimates are tricky, because they're so dependent on things like rider weight, riding surface, wheel bearing condition, ground slope, average speed, etc.  The same goes for any performance metric (like how steep a hill can it climb) but range is the one compared most often.  


For our board, we both computed it mathematically and also rode the board a lot and measured the range on each ride.  Our 20 beta testers also recorded their rides using speed tracking apps like strava or cyclemeter and told us the range they got.  6 miles was a good average, with some riders getting 8 or 9 miles using techniques like pushing to accelerate or gently coasting up to lights and stop signs.  


They’ve still got that sexy picture of their board back when it was so skinny. Still no word on their final production specifications. To my friends at Boosted, keep up the hard work! We’re all waiting for your boards!


Finally, I’ve ordered a Carbon series board from Evolve. It will be my primary board, and my Snubnose model will go to my girlfriend. Finally, we’ll be able to ride together. Evolve says they’ll have it to me some time next month. I can’t wait.


I’ll leave you with a video my friend made of us longboarding down campus.
