So is there anything you are not happy about with your build. Surely it can't be that perfect.
The mounting and dismounting of the battery is a bit tricky, I knew it from the beginning but I just accepted it. Best is not to dismount it and charge it while the side panel is slightly open. I live in ZÃƒÂ¼rich in a rental flat. We have a bicycle room where of course there is no electric plug (otherwise the 24 parties would have to pay part of my electricity bill). That's the main reason I wanted to make the battery removable for charging at home. It turned out that its better to charge it while I am in my office because here I have more space and I just take the bike upstairs (elevator) to charge it without removing and remounting again... (distance home - office < 1km, I could walk easily...
If you don't have such problems to get the plug to your bike directly I would suggest to make a case that's screwed together and has to be opened just occasionally providing a charging port on its outside.
Another thing is the placement of the Cycle Analyst and its display (by the way its two 3 mm acylic glass plates glued together and then fully glued in, there's no way for water to ingress). As I decided to place it also in the case this was the only reasonable position. Means I did not plan that in the beginning. Best place for me would have been at the top front where the controller sits but there was no space left. I do not need the CA while riding so I don't care. Just sometimes it would be nice to read the velocity but that are exactly the moments it is to dangerous to look between your legs and not on the road...
Then finally one important decision is how you fabricate the fibre glass thing. you have two option: positive or negative. I read in those forums as a beginner it's a good choice to do it the positive way. pros: easy cons: you lose your form, there's need of grinding a lot but that's negligible if you just fabricate one piece THEY SAY.
I say: negligible? It's f***ing arduous! Really I spent days in just making the surface planar...
Consider doing it in two peaces if you can, with the visible surface lying on the form. That would be professional.
It's German but take a look at the images.
