Re: Gearing, speed, and the like
Well you've actually posted 2 questions but they are related.
The first on tq vs accelleration, the second has to do with bike setup. Realistically it's important to understand what your goal is. You won't necessarily be running the same gearing and tires if you're looking for fast 300' times as you would for hill climbs or for xc racing and trails.
If your goal is to get as quickly as possible to 70mph in a straight line you'll have different gearing than if your goal is to get to get from one corner to another on a flattrack or xc course. So if you're trying to go faster then increased tq combined with the appropriate widening of the gear ratios will do the trick. But if you're shooting from corner to corner you just want to get to the highest speed possible in the straightaway instead of worrying about an extra 5mph you might not have the distance to reach with your engine output.
It's a lot of trial and error for different situations. Many of the top hill climbers are running 21 or 22" paddles w/ 6-8 paddles on 12/44 or similar gearing to keep wheelspeed high up the hill. If you're running on flat dirt you're going to go with shorter tires (18-20") and taller gearing to keep traction and speed.
