Finding the right cranks to cut the spiders out of to allow me to fit it all between the pedal cranks whilst keeping it looking central and getting the chain where i wanted it. on this build everything just fits. To build a frame would involve designing a whole bike and making many more components than just a frame. I started this one by cutting some cardboard templates of the motor, batteries and controller, then i taped them to the bike frame, i spent a couple of evenings moving them around thinking of all the possible implications associated with that layout until i found the layout that i have now, then i stuck them in place and sat with a note pad and a couple of rulers, i try to think of every single small detail and how i will do it, when every single problem has been solved and i know exactly how i am going to do it down to the last tiny detail i will set about it with the hack saw and get stuck in.
Now what was the question,,oh yes,,how much for a frame ,,, priceless!!

You hit the Nail on the head. I am designing a new frame with the intention of making it suitable for a multitude of different motors from hubbies in the wheel to a variety of mid mount options. I am going to build several complete bikes all with different motors to work out the finer design issues and then when i am happy i will produce a batch of frames.
It will of course have to look like which ever motor is used that it was made just for that motor, i wont be happy with the design untill i achieve this. It also has to be able to accomodate a multitude of battery options and controler sizes.
I allready have the basic design planned out, i just need to buy several motors now to work out the finer details.
