the best electric bicycle of the world image
Schiff G
Assuming the solar panels are not connected to the power grid, and assuming an average number of miles traveled per year (say 12,000), and without discussing battery, motor, range or other issues - but assuming it's 100% electric (not a hybrid), and assuming plenty of sun location, how many watts of installed solar capacity is needed to power the car (visualize a pratical car like the EV1 - not like the "cars" they have in the World Solar Challenge race) w/o any other power source? Err on the side of a few too many watts rather than not enough.
Answer
Electric cars get 2-4 miles / kWh. A golfcart type will get more. An electric bicycle can get 100 mpkWh.
Okay, so lets say it gets 2 mpkWh. that's 6000 kWh requirement per year. That can be supplied by a 3 kW array if you live where I do in California. Probably a somewhat smaller array in Phoenix, Arizona. What you can do is look up the average number of peak sun hours for your area on

Let's say the number you get is 5 hours per day. Multiply that by 360 days per year, and get 1800 hours per year. Then you would divide that into 6000 to get the size of your array, in kW.
Remember, this only powers the car, you would need more if you want to power your house, too.
Good luck!

Legal to ride motorized bike on sidewalk in Florida?
tiger1441
I am wondering if it is legal to ride a motorized bicycle (60cc) on a sidewalk in Florida. At top speed this thing only goes about 25-30 MPH. Do I need a permit or license first? Thanks in advance.
Answer
No. Nowhere in the US (and probably the rest of the world) is it legal to ride a motorized bicycle on the sidewalk. In fact, it also not legal to ride a bicycle on the sidewalk.
http://en.wikipedia.org/wiki/Motorized_bicycle says: "...In the United States low-speed electric bicycles (top speed under 20 mph and under 50 cc's or in the case of electric models 750 watts) are not considered motor vehicles by the federal government and are subject to the same consumer safety laws as unassisted bicycles...
Which means that if it's more than 50cc or can go faster than 20mph, it is a motor vehicle.
It needs to be licensed and so does the driver.
