So it was my birthday this week. 24 years. It was quite a good a good birthday. The norm is probably to feel older, but if anything I feel stronger; that must be due frequent attendance to Pump class recently.
My bike also hit a milestone (a birthday of sorts if you will); 1000km. Here’s photographic evidence of the momentous occasion:
The photo was taken just after Joondalup Drive and Kendrew Crescent. Just after because 1000km was hit dead on the intersection; a very inconvenient and dangerous location to stop and take a photo 
The journey to work is around 11km. This translates to approximately 90 return trips. If these 90 trips were made using public transport, they would have cost $324. With an overall investment of $600 into the electric bike, this means the investment is almost half paid off!

Eagle is powered by several lead acid batteries connected together. Lead acid batteries are the most basic type of battery you can use to power an electric bike, as they are cheap. The are cheap because they are relatively simple, stable, bulky, and have a relatively low energy density (compared to Lithium ion). Given the experimental & sandbox nature of Eagle, I chose to use lead acid batteries to save on cost. They should also provide enough range for me to get to and from work; any more range would really be wasted and bloat the overall cost. Read on for some more details specs on the batteries…

About a month ago it occurred to me that, 1) I work for a start-up company, and 2) no one at work owns an electric vehicle. This seems to buck the stereotypical start-up company image of ultra-geeks and their battery powered transportation. After some quick googling, I found that electric bike conversion kits were quite reasonably priced…
