160F at how many volts each and how many caps in what config? Or you can just give us the result of 1/2CV^2

:-)

@paytontech in fact the 160F materialize down to a few F because they are in series, all of them... Using no buck-boost converter the capacitors are designed to work up to the open loop voltage of the solar panel. If you take the sum out of the inverse of eight 160F capacitors and take 21V you will get 2.45 Wh but the motor will not be able to use all of it - at the lowest voltages. Even if this looks as a mall amount it is sufficient to move the bicycle a few seconds- as shown in the video.

yeah... i see a huge problem... you have to ride into the sun or it wont run... i didnt see any batteries so it appears that it would run straight from the sunlight...

@1986IrocCamaro: It has some supercaps, those are used for the driving you can see in the video.

This is cool! A lot of the commenters don't realize you can use the panel when the bike is parked and store the energy for later.

[gerfriedc]

@alexkram: exactly!

lol, get a small 5volt solar cell and strap it 2 a helmet 4 extra power/speed

Just another of the many scams from people claiming to have a "solar powered bike". Even with a very expensive set of solar panels, it can take 3 to 5 days to recharge a battery. Beware of anyone who uses the word "solar" and "bike" in the same sentence. It's all a scam and just read the comments and you'll see how many suckers are out there.

@MrAfroSheen It's quite possible to have a direct solar powered electric bike.Have you ever seen those Solar Powered racing cars they have been around for decades.

@MrAfroSheen Hmmm. You've been misled. A typical electric

bike can be recharged in under six hours using four square

meters of solar cells. The cost of said panels is only a few

hundred dollars and the LiFePO4 battery is about $150.

@MrAfroSheen i have a solar bike but I only use the solar panel to charge my battery for my headlight and mp3 player.
