John in CR said:I only wear the helmet when I go on the highway, ride on roads with which I'm not intimately familiar, or the roads are wet. That means 90% of the time my helmet is a baseball cap turned backward. The 166kph was a one time shot for you guys. The advanced timing wiring was creating too much controller heat, so I fixed the wiring and now it only goes 150kph+. Imagine if I didn't weigh 120kg and addressed aero, so the voltage didn't sag over 15 volts down to 101V.
Keep in mind that run was after 5 miles of riding including a 142kph run, so the motor was heated up pretty good, and the voltage was already down to 119V from 124V. On top of that the darn EB2xx Infineon controllers running the motor weren't playing well together and I couldn't get to WOT throttle.
All that said, my next speed run will surpass the Brammo Empulse's top speed of 169kph. I found a new rim I'll be able to mod to run a 16" moto wheel instead of the 13" scooter tire I've been running. That will take me to about a 21.5" diameter wheel instead of the 19.2" I've been running, so a run on a fresh charge should do it. For insurance I'll boost voltage a bit, and use a lower more aerodynamic cargo bike that will double as a highway rocket.
Just to bring things back to topic, when I take my bike out on the highway I've yet to get a single comment from a stranger, even those who chase me down after I slow down. I guess it leaves them speechless and reaching for their cell phone cameras. 8)

PS- Why is everyone so worried about my footwear? It's not a Flintstones bike, and I'm careful enough that my feet only touch the ground when I stop. Sure if I was riding on a racetrack or offroad where going down is just part of the sport, then I'd have to get riding boots and fully armor up, but in regular street riding the more exposed you are, the more careful you ride. At least that's the way it is for normal people. I love the free feeling of riding feeling the wind, and I don't see a whole lot of difference between riding around in a cage or wearing one.
I'm pretty sure you don't hear about 90% of the comments about your bike since you are about a mile away before they figured out what happened.
