Hi all,
For some time now I have been planning out the build for my wife's eBike, using her Huffy Panama Jack beach cruiser. Yes, I know, I really wanted to use a different frame too but she insisted since "it is so cute". She said that if I really wanted to build a bike for her, that I needed to keep it clean and retro. My bike was built for balance and speed, none of these fashion concerns! LOL
So, let the planning begin...
The goal was for a 30 MPH ride that required little to no pedaling, since the neighborhood speed limit is 25 MPH. And a 10 mile range would get her to and from Walgreens, friend's houses, corner store, etc a couple times between charges.
Here is what I ended up going with:
- Huffy Panama Jack beach cruiser
- Front cantilever brake forks from my Schwinn build
- 9C 2807 rear hub motor
- Lyen 12fet 3077 controller
- 15s2p (10 AH) Turnigy lipo (because of the size/weight and I already have the charging setup for them)
- CycleAnalyst v2.3
- 2x Grintech torque arms
- Rear Tektro C326 caliper brake (on order)
- Hand made leather saddlebags
Being a step-through frame, I knew that I was going to have to put the batteries and controller in saddlebags. Thanks to Paul's leatherworking inspirational posts, I decided to give making my own bags a shot. So glad that I did, because I think they turned out pretty good for my first attempt!
In this picture, you can see the on/off switch in the side of the left saddlebag so the bike can be turned on/off without opening the bags.
At these power levels I could probably get away with just one torque arm, but I went with two to be safe. One oriented upwards, the other down, to account for both acceleration and regen braking forces.
