"He knocked his block off!" (from the TV ad).I like the rams horns just the way you have them. Just spin the grips around 180° and grip them from underneath.
Rock 'et like a Robot!
I made a bike like this from a 26" frame in 2007, but never could ride it, the front was too heavy to control. I was going to make a go of it again for this build off but saw nothing but problems so I didn't go for it, but I researched a lot about a front wheel drive bike.
The Cruzbike has been around for awhile and people ride those just fine, just takes some practice they say. It's the pushing left or right that tries to turn the bike making it hard to maintain balance.
They say you push outward with your foot at the same time as pushing forward to maintain balance. I never tried that but it makes sense.
One suggestion had both crank arms positioned together so no sideways push would happen. I was going to try that as a last resort before I gave up on the whole thing.
