Ok, all that came as a bit of a shock!
I've spent ALOT of time researching allready, pretty much all my spare time for the last couple months. But apparently still went wrong? By the way, KiM, loved reading through your build! Why did you say "tipping over"?
Definately a little discouraged by the news but, I still really want to get this project going. So i've been thinking it over for my motor options. I don't want to bother any of you, but after making the wrong decision once already I don't want to make a repeat. Could you give some input on these thoughts?
My Original motor
http://www.hobbyking.com/hobbyking/stor ... oduct=5139
48v x 150A is 7200 watts or 9.6 HP x2 would give me max 19.2HP
This was the motor i was planning on using before I got on the RC motor kick, which as I understand it is same as ETEK? But 48v x 90A is only 4320 watts or 5.8 HP continuous, another page says 15 hp max.
I don't understand, if two turnigy's give more HP than an ETEK where did I go wrong? Or would I need two ETEK's??
I heard on another forum the idea of comparing the available HP to the weight of the vehicle (give you my example)
Geo Metro 1.3L 70 HP around 1765 LBS = 25.2 lbs/HP (driver weight included)
My Bike 19.2HP around 664lbs = 34.58 lbs/HP (driver weight included)
So i figured it would perform a little less than my metro. I'm only looking at being able to do 90-100 kph MAX. Most of the time traffic won't let me get past 90.
I have included a spreadsheet i found online that helped quite a bit. Made a few minor changes myself but nothing that effects any formulas.
Another thought (Might be retarded) But what about connecting two of the motors together end on end with the shafts joined in the same phase, could I then run it off of a single controller? Set up this way would be two connected motors per side with one controller each. By the way, controllers are undecided.
Also, I would consider modifying the bike to ride lower but will have to wait till i have a look at it b4 i can discuss more.
One more thing, i am planning to use AGM's only at the start as proof of concept for my wife who is quite skeptical about the whole thing and doesn't want me to blow 2-4K on LIPO's if it won't work. My plan was to go through one set of AGM's and then upgrade to LIPO and reap the rewards!
