This dude hasn't legs, but much "balls"! Repect!

This is great design. How many speed does this tricycle have?

Thanks

effectively disengage that wheel from the diff, so you could have drive power tightening your turn and keeping your momentum forward in, say, an uphill corner, while the brake prevented the kind of "plowing" normally associated with a limited-slip diff in a front drive vehicle.)

[azraphale]

(Of course, dual front brakes with front drive would require a center differential, and if that were limited-slip as you would basically need it to be, it would have to be unique so as to allow forward torque to drive both front wheels, but reverse torque to allow the other wheel to free-wheel). A side benefit of a setup like that is that it would allow tighter turning than a limited slip diff normally allows on a front-drive vehicle because application of one front brake while moving would

are not activated separately as-is, you could move to a single inboard brake for both front wheels (although I can certainly see where having separate front left and front right brakes would be an advantage if the control interface was easily usable).

suspension. Wouldn't even be that hard to make a very small, light clutch pack-based limited slip center differential, or one that was manually adjustable even, so that the rider could control the front/rear torque split as desired. A side benefit of having front drive (even without rear drive at all) would be having inboard front brakes, thus reducing unsprung weight and allowing more efficient brakes with less overall weight penalty. In fact, if the brakes for the two front wheels

[azraphale]

I would think that wider rims and bigger balloon tires might be valuable here, although the extra weight might cancel the potential benefit. It also seems possible that with the minimal torque produced by a rider, you could probably power the two front wheels with very narrow driveshafts (titanium would be ideal, but billet aluminum would probably do at the cost of a bit more weight for the desired strength) with small universal joints on them to allow for the fully independent front
