I’ve known about this guy for a while. In fact, I bought my e-bike parts from him. Last summer he rode his e-bike across Canada. He went from Victoria to St. John’s for $8.57 in “fuel.” At that rate, he could go around the world for the cost of filling up an SUV!

Now I have to lean on him to get a version of that bulletproof controller! The controller I’m using has a tendency to go “poof” under load and lock full-on.
