Now that the ebike is running smoothly. I'm thinking about upgrades! :-)
The first thing that sounds interesting is to increase the voltage of the bike to 48V from the current 36V. 36V is fine, however, I'm always looking for a bit more oomph. That being said, the other problem with my 36V battery is the weight. The 36V battery weighs 21 lbs. That doesn't sound like a huge amount, however, I'm finding that I'm only using about 3.5Amps on my ride in! That's a lot less than I expected. I can reduce the size of the battery and increase the speed if I were to switch to a 48V 10 or 15AH battery.
The other important thing to think about now is lighting. The hours of daylight here in Washington, DC is shrinking and lights will be necessary soon. Both front and rear lights. I found this very interesting light online.
It's supposedly a 900 lumen light in a relatively tiny package for only $80. That sounds like an amazing bargin and I may need to try it out to see how well it works!
