    Exploring options on electric car build

    I got the bug to build a fast electric car. I have put out the word to my local used car dealers to keep an eye out for a wrecked Tesla. I’m open to other motor options. I know the Tesla motor has the power. The chassis will likely be a Factory Five 818C. This would be a cheap, light easily...

    BMS limiting my charge to 54V

    I replaced my old 22P cells with 35E cells. Lately it seems I can only get the battery to take 52V (48V battery + 48V charger). I tried different chargers including a 52V charger. Today I charged it again and like before, 51.9V. If I turn off the charger and start over it charges...

    GNG Gen2 build

    I found myself here at endless-sphere.com over 3 years ago when I started looking for information on Ebikes. Since then I have built several ebikes as well as helped friends with theirs. This summer I built a bike using a GNG Gen2 kit. I am very pleased with this kit. I have built about 7...

    Battery puts out 54V until I plug in the controller

    I will try to keep this short: I have over 2000 miles on my Ebike since 2013. Everything has been great electrically. Since my battery hit 2 1/2 years old I have had a small decrease in range but nothing that would not be expected. One day the bike died during a 6 mile ride. I got home and...

    Power draw when turned off but still connected?

    I built an Ebike using a GNG gen2 motor kit. I bought a throttle with a power switch and a volt meter display built into it. The controller has a power plug where there is a smaller red wire along side the big red wire. I assumed this small wire is the on/off switch option. I clipped this...

    Swapping old 18650 cells with new ones

    I have a 48V 10Ah eZee Flat Battery that I bought new in 8/2013. It has served me well but I have lost some range starting this winter. I am curious if I can simply buy new 18650 cells and replace the old ones. I have a spot welder and have practiced on some batteries already. The original...

    NuVinci 360 installed in fat bike rim

    So a customer gifted me a NuVinci hub for my bike. He originally bought it for himself but his new fat bike rim has 107mm spoke spacing which is much much wider than the NuVinci hub. After I installed it on my bike I got to thinking. All I would need to do is make the hub wider. So I...

    Building a gizzmo for controlling a fuel injector

    I have a simple device I want to build. It’s not Ebike related but you guys here seem pretty tech smart and can probably help me out. I want to build a device that can cycle an electric fuel injector with some type of user control on injector dwell time. This will be for adjusting the engine...

    My current Ebike build from scratch

    As I planned from the beginning, I will be building an Ebike from scratch. My GNG mid drive kit installed on my current bike so easily, I couldn't help but put a month or two of riding on it to feel things out. The frame, bottom bracket, motor plates, rear swing arm, and miscellaneous mounting...

    GNG mid drive kit on my bike

    http://www.dailymotion.com/video/x12yjgf_bike-ride_sport I made a quick video of me riding my MTB, now Ebike, in the trails near my home. This was made with my GoPro camera. The uploaded video seems to be lower quality compared to the original. I went with a mid drive for my built thinking...
