@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...
I have a better idea for mounting your solar pannel, on the bicycle, make a u- shaped roof which covers, from the top of the back wheel to the top of the front wheel, and on the roof , spread your solar pannel. You can easily fit yourself inside the u0 shaped room.
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.
i like r bike anything but a gas hog car.i have a trike i put a phoenix hub motor on and i go about 25 miles with no peddling before i need a recharge.i have about 3000 miles on my bike now with no problems.i have tried several different motors and think the phoenix is the best ive tried so far and it goes further and has more power than some ive tried.i am wondering how your solar panel has held up?i tell everyone i put a motor on my bike because i heard it was illegal to pedal azz.have fun
this is cute, but a 50W peak output solar panel is too week to be considered practical for transportation. As any cyclist will tell you, a 50W pedaling power is nt much. A racing cyclist riding at ~25 mph produces ~200W for a few hrs continuously. The 50W panel is a peak output, so the average output will be even less 2...4 times less (e.g. cloudy day) One would need ~10 of these panels to get a bicycle to match the power output of a typical human bicycle racer.
Good job mounting the solar cell! That particular bike is inefficient but we all know that so no real criticisms. I would like to duplicate the same type of front mount only I hope I may afford to go on both sides as well. This way I may carry smaller (& smaller) battery as long as more cells can be mounted.
This setting is to test ultracaps/supercaps - the 12V 50W solar panel is not able to drive the vehicle at significant velocities, also because it has a 24V motor. First the efficiency of the solar cells has to be doubled at least to become a viable alternative for batteries. A second panel would be an option but it increases the weight by another 7kg and the mounting is not so easy as fort the first panel.
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

@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.

@floatinsun ok good idea - 2 problems arise:
1. the curved roof is not 100% compatible with crystalline PV, you have to use amorphous low yield stuff
2. extra artwork required to fix the roof without restricting the steering possibility
But I will do it anyhow if I come across a feasible solution, may be dye type...

@MrAfroSheen i have a solar bike but I only use the solar panel to charge my battery for my headlight and mp3 player.
ilikepie9519 8 months ago
@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.

Good luck, don't forget that a 50W panel adds 7kg, but may be you find lighter ones...

where did you get the solar panel - three panels would work to charge my e-bike!
RockinJoeDavis 4 years ago
ordinary 50W 12V solar panel - I bought it used and it peaks at 20V charging my supercaps.
Three panels and a buck boost converter would run the bicycle but add weight and I dunno know where to fix...
