"Instead of building a bicycle around electric power, GeoOrbital is a universal wheel you can swap into your existing bike to power your ride."

"The device replaces the front wheel in bikes with 26 inch or 700c (28 inch-29 inch) size tires; either way, its proprietary foam wheel won't get a flat when punctured. Its lithium-ion battery boost your bike up to 20 miles per hour for up to 50 miles, has a USB port to charge your devices while you ride, and recharges as you pedal, brake, or coast downhill."

This battery powered swap-in 'E-tire' may be more attractive to those interested in an E-bike rather than buying an entirely new bike. GeoOrbital says the retail price will be around $950.

The laws of physics cannot be denied:

Momentum can be defined as inertia in motion. Moving objects have momentum. Momentum is how hard it is to get something to stop or change directions. Momentum is mass times velocity, or momentum=mv. The heavier something is and or the faster it's moving the more momentum it has. The more momentum something has, the more force it takes to get it to change velocity and the more force it can apply if it hits something.

At the moment of impact, the full force of the the inertia in motion is released upon the point of impact regardless of where the density of weight is located.

I haven't had a conflict with an e-bike, but I reserve the right to complain about them, even if they have a legal right to use them in bike lanes.

I mean, Segway riders have a legal right to congregate on lakefront sidewalks, but I can still complain about them.  I can even suggest that they perhaps shouldn't have that right, having essentially purchased it from politicians unconcerned with whether it is good policy...but I digress.

This is Greg Valent's homemade electric assist cargo bike. Photo was just posted. Nice Greg!

Can you give us some info on how you put this together?

If you think things would be worse with E-bikes in our bike lanes, check out this article from today's Tribune about the hectic motorbike scene in today's Saigon, Vietnam.
