Electric Bikes
#41
A quick search at the University of Google shows this:

"Regenerative braking is marketed as the holy grail of electric bikes these days as people dream of infinite battery life. But while it is true regenerative braking does extend your range by up to 10 percent, you have to ride 200 miles downhill just to charge the battery enough for a 20 mile ride."

Not very practical, alas. Still, a 10% increase in range would be nice to have.

The idea of Regenerative has been around with bicycles since the end of WW2.   When the UK was converting back to civilian production an Industrial Designer named Ben Bowden created this futuristic bicycle which would have an electric motor with battery where the peddling on level ground would recharge the battery.  Then if a hill was approached the helper motor would kick in.

This piece was for a Trade show called "Britain Can Make It".  (meaning that they could make
about anything the world would want)   This bike was made of pressed aluminum, the motor was in the
front wheel and the battery under the seat.  It was called "The Spacelander".   The shortcoming was the battery technology of the day was
inadequate for the application.   So the bike was later made of fiberglass and sold on the merits of it's styling.

Fast forward to 2017 and this news story:

Lithium-Ion Battery Inventor Introduces New Technology for Fast-Charging, Noncombustible Batteries

This may be a real game changer for the battery powered world.  I can only imagine what this may do for Solar Panels.  I'm thinking where the panel has the batteries built right into them without a lot of gain in weight.

So these battery powered bikes may begin to come into their own for Van Travelers.  Imagine a bike that is covered in photo voltaic that will recharge when locked into a bike rack in a very short time.  Too good to be true ?  It may not be that far off.
