How's it handle on loose stuff? I've talked about building a 2wd for years with 2 benefits in mind:
1. First of course, is having the extra power with double the cooling.
2. Handling, I've always thought that having a powered front wheel would be a benefit if traction is lost on the front wheel, because even in the slickest of situations the front while under power would provide at least some force trying to keep you upright. I remember 8 years ago my front wheel drive first hubbie had a positive effect when I encountered loose gravel or sand on the street instead of just sliding out from under me with unpowered fronts since. Anything that reduces the chance of eating any more asphalt is a plus in my book, and before anyone goes there, each and every occasion was while going slow and at low power.
Hey John, I haven't really tested 2WD on the dirt, I built this bike to be a capable street machine and eventually track weapon.
1. Cooling / Power is one of the reasons I am developing 2WD. A MXUS 3K Turbo mounted in the rear is getting very warm / hot when ridden spiritedly. It is a light motor, 20lbs. I am trying to see pairing it to a front hub will make the motor run cooler and more effectively. Having a 20lbs hub compared to a 30lbs hub like the QS motor makes the hub handle much better. I am still tuning the setup closer to 50/50 power split. Right now its 1/5, so its rear bias.
2. The front hub acts as a stablizer so that straight line acceleration is very smooth because you now have forward propulsion, also moving some of that weight from rear to the front by using a lighter rear hub results in a better balanced, better handling machine. I barely got to ride the bike today, it is still undergoing tuning or other developments. Using 2 Cycle Analyst to monitor both systems independently.
