Motor Burnout So i got everything together on the outside of the bike to give it a first test ride around the factory, it was working on the stand, all good. Then as the guys were playing with it, spinning up the back wheel with it off the ground they did a kind of burn out on the floor (motor...

I have seen integrated motors and controllers, but I enjoy the modification and making my own things so I want to learn more about how it all works. I've been looking at some of the other threads for stealth builds and I don't think I'm doing enough, I wondered if I could be rid of the frame...

Controller Simplification I managed to find another supplier of this controller, the YK85S (different to the YK85), to request an electrical diagram and got the following back. This let me cut back and insulate all the wires I don't need, everything but the key switch, battery, motor, motor...

Controller Confusion I've been trying to get my head around the controller. The wire colours appear to be completely different to what stated on amazon where I bought it. Some of the connections seem crazy to me! There's a two wire connector that is is 36v with no protection connecting to a...

Thanks for the kind words George. My background is in Industrial design so I do have a drive to get the little details right. Frame Bag Mock Up I picked up the leather jacket I'm going to use to make the frame bag yesterday and even though it's small, there's ample material. I managed to make...

@J.R. Thanks I had a look at their leather. It is more money than I'd like to spend, i got a second hand jacket on ebay. @GeorgeS Those connectors look great! I need single wire connectors though like on the phase wire i think. my battery positive and negative will be in different frame tubes...

Frame Modifications - Second Head Tube Hole I got some carbide die cutter bits this week to make the second head tube hole a bit easier than the first. It made such a difference with them actually cutting the metal instead of grinding it off with the stone bits. Both holes finished! The next...

I drew up in CAD a 2d model of the packaging of the components, it may help you understand the project a little better. I have also done as I said and found some conduit pipe with the OD just smaller than the ID of the frame tubes. I added some a few more wires down the pack as redundancy...

Great Info! Thanks. I'll update once I've done my tests with the complete pack. I am planning to take this apart to get the tightest packaging I can. I keep minimal wiring on the outside of the frame and a more discrete look I want to use a leather frame bag like the one below. Adding a...

Thanks! Ah. The Battery is one of the aspects that I think will need ongoing development. I was planning on checking the voltages on each of the balancing wires in the pack before charging to see if it was drastically unbalanced. From what I have read there shouldn't be any issues with any of...

Hi All. I'm a little way into my build now and I thought I would share my experiences. My main goal for the project is to build an eBike that doesn't look like one. I recently got a single gear bike to try because i like the aesthetic and simplicity. A bike like this has a compromise with the...
