Few quick questions:
Regarding wheel size:
What would you recommend for a vehicle with about 4KW of power? It's not even close to finished yet so I have no idea how fast it will go (but I'm assuming pretty fast). 9 or 13 inch? I'm thinking 13 inch would be safer but I've seen some 9 in. wheels in a store around here I like.
Regarding battery pack:
Don't even suggest lithium because there's no way I can afford a suitable pack. Even NiMH is way out of my price range. So basically I'm going with SLA. Thing is, what would be a good brand? I've heard good things about B.B. (I think that's what it was) batteries but I have a new PowerSonic 12v 35AH battery sitting in my garage left over from...something or other...that I would like to use. Unless I find out it's a total POS I'll just go buy 3 more. Would this be a good idea?
Regarding power train:
This is my big problem. Not even the slightest on what to use. I'm gonna need some low end torque to get this thing out of a standstill. It's probably going to end up weighing over 250 lbs. Then add my 175+ onto that and using a single gear ratio is completely out of the question. I'd like a decent top speed, thank you. The only thing I could think of that might work is the rear sprocket cassette of a mountain bike. However, I don't know if that will hold up to the kind of torque and/or RPM I would need it to.
Other than that, the only thing I could think of would be to modify a torque converter (I think that's what I'm looking for) meant for a go-kart. Could I even do that?
If anyone could give me their thoughts...
