First test


OK, so I designed this machine to get me to work, 17 miles from my home. After the first ride, I drained the pack to the point of damaging a few of the cells. It was a very expensive ride indeed. This happened especially because the front brakes somehow managed to lock down on their own, drawing many wasted amps from the pack. One of the cells managed to bubble past the cage I made for it, so I will have to do a bit of work to get this thing back to its awesome state where it belongs. Needless to say, it does not do what I need it to do so I have decided to sell the machine. Someone will be very happy to own this vehicle, maybe this will finance my next one?

To do list:

1) install metal sheets in the end of the cages to resist battery bulge
2) re-test the BMS, I think I may have damaged one or two of the cell shunts
3) Back off the front brake caliper adjustment.
4) Apply "EFZR16kW" decals that should arrive this week.
5) Bring it to Thunderstruck Motors to get the controller programed
6) Sell it, preferably for a profit considering my time and cash investment

How it started

I have always thought, what would happen if we couldn't get any gasoline? With oil being something that we have finite supplies of, I realized this will be a reality one day, yet, no one seems to be preparing for this eventual fate. This seemed really dumb to me so I decided I would build a vehicle that could "weather the storm" so to speak. I did research for a few years around diesel engines. I learned they can burn lots of different things, and this seemed like a suitable choice for a post-apocolyptic vehicle. I have always loved motorcycles, cars seem like a boring waste of space to me, that is why I own four motorcycles and no cars! One thing I love about motorcycles is that they go FAST. After going through a lot of specs on a lot of diesel engines, I realized it would be beyond my skills to make a fast diesel bike. It would either be huge, heavy, highly engineered and somewhat quick; or small, reliable and slow as slugs. It was at this point that I started looking into Electric motors as a new choice for the ride of the afterworld. Electricity can also be made (and stolen) from many sources. So I started in on my research in electric vehicle technology. I realized that the new constraint here would be cash money. The motor and batteries I wound up using cost me almost $6000! I could have fit another $4000 worth of batteries into the frame I used, but, I am happy with the performance and weight of the machine I built. Lets move on...



Better Late than Never


OK, so now that my electric bike is Complete, running, insured, and ON THE ROAD, I will share with you how I did it and what inspired me. Let's start in the begining....
