aloha all , only just started this project and already each question opens another can of worms lol
 im looking at a duel motor set up on a larger sport bike and therefore am on the hunt for a controller anyone got an idea ?

[Bogan]

What motors have you got in mind? and will they be wired in series or parallel?

[helco]

see like i said one questions opens up way more , i guess my first question should have been .....
If i run duel motors on a larger sport bike how does series or parallel effect things and does anyone have experience of this and the controller !
 there we go a much better question to start the ball rolling................lol

[Bogan]

Series is more torque but less top speed, parallel is less torque but higher top speed.

Unless you're building a race bike, the extra weight/cost would imo be better spent going on batteries, and go with a single motor, moderate performance but decent range.

[frodus]

lets back up a bit and start somewhere else.....


what bike do you have in mind for the conversion?

What kind of performance and range do you want?

this has been a very brain heavy couple weeks , what started as a simple "build an electric bike" has turned into a quest to build something i can be proud of.....the more i research the more i want to build something that will perform and at the same time teach me about a tecnology that will do nothing but move forward , from what i have read in the last couple of weeks the fun stuff is in the experimenting , but first i should build something that will teach me some stuff , so the plan so far it for twin agni 95rs and a zilla control , this coming week is " battery " week , more readin and head scratchin , i know these choices will not be to all taste's but the "2" speed idea intrigues me ,and i can start with the single motor and add the second as the build progresses .
 To answer the question as to what bike , i have a VTR 1000 , i wanted to build something on the bigger side not a 250 mini thing , the frame of the VTR lends it self  to " hanging " motor and battery pack as once the V twin is removed the wishbone frame will lend it self to low battery placement and a good center of G.
 I have my own CNC machine shop which i have run TOTALLY off the grid for the last 4 years ,so in the last four years i have done a lot to learn about power generation and storage and conservation , its time to burn that power on two wheel and have fun !!!!!
