Sure I will be happy to be in judging panel and will definitely post my opinion for deserving winning candidate

I would like to volunteer myself for judging in categories of circuits and workshop

Absolutely riding this bike is fun though not punchy acceleration but it's enough to beat most 100 cc two wheelers till 35 to 45 Kmph mark after that the person can overtake me but that's the most speed you can manage to have in congested Indian cities. Thanks for your time and interest ✌️👍😊🙏

Thanks

आपका बहुत-बहुत धन्यवाद और जो आपने बात कही मुस्कुराने की उसे हम जरूर ध्यान रखेंगे आगे से और भी वीडियो को इंटरेस्टिंग बनाने की कोशिश करेंगे

Now I have immediately sorted out your complain hope that now the links do take you to the right supplies

Sure it's a matter of concern just let me check

Welcome 🙏

Bhai bhai Gujarati kyay pan Mali jai ho..all the best

Thanks a million for appreciation. Yes if pulley on drive shaft is larger then you won't get much top speed and all what you get is tonne of torque it would be like tractor. No high speed but lot of traction and torque at wheel.

Ya I have made battery pack my self I have all the stuff for making professional battery pack. It costed me around 36000/- INR entire conversion costed me around 65k including fast charger and old bike cost not included. I actually had chain drive in my first version instructable available for that as well. But I upgraded it to belt drive because it's much smoother and very less noisy than chain drive. Chain drive lasts longer but using belt drive I found to be more safe and I am not stressing drive belt too much as secondary transmission takes the most load to turn the rear wheel. Do worries feel free to ask me any questions you may have

Thanks a million for appreciation

Hi thanks a million for appreciation. Links are shortened so it's not showing the hyperlink or may be some other reason but you can copy paste the part after word link and arrow to get that part ordered. Still I will check if I could provide clickable links ..

Thanks a million for warm appreciation.

There are lot of parameters for building a motor and it depends on whether you want to build BLDC motor or PMSM motor? Or if you are planning to build it for a car you may go for induction motor too. So it will not be possible for me to suggest you the wire guage for motor as it needs lot of engineering designing calculations depending on type of motor. I would though suggest you to apply for free courses available online on various disciplines so that you can get better idea of what you are looking for and move forward in that direction to get that done. Thanks for your time and interest.

Hi Thanks for your keen interest. Motor is BLDC motor 1.2 KW erikshaw. And I have sourced it locally but if you are from India you will get times of those at dirt cheap rates in Delhi. It will cost you around 7 to 8 k for genuine one. Do let me know if you have any questions.

first of all thanks for your time and interest. Yes, all the gears of old petrol bike work the same way as it used to. Now regarding your second question that does electric bikes need gearbox the answer is yes and no both and I need to elaborate it as belowelectric motors due to their high starting torque may not need the gearbox but if you are using an adequately large motor with a lot of watts of power and in that too the motor needs to have the final reduction drive which increases the final wheel drive torque to provide that EV a traction capability under varying loads. Now scenario two is that we are using a lower power motor that does not produce the large torque which implies it does not have that large starting torque either. So for that reason, I have used the old bike gearbox as…

Now scenario two is that we are using a lower power motor that does not produce the large torque which implies it does not have that large starting torque either. So for that reason, I have used the old bike gearbox as a four-speed torque converter which will provide traction to the vehicle under various load conditions and will manage to pull large loads owing to lower inherent torque curve of the motor. So I hope that I have answered your second question. Now the advantages of this system of using four gears are as below1) Can carry much higher loads than that the motor is alone capable of.2) This setup optimizes the usage of battery and strain on electronics plus large inrush of current can be avoided thus making the system lot strain-free and saving the valuable battery life.3) I am able to take advantage of using the smaller motor and than too able to achieve lot of load-carrying capacity even though the motor still remains in its efficient range.4) I can use the higher torque or higher speed depending on my need just like a conventional motorcycle which gives me very confident driving experience similar to what I am used to since years and than to I am not locked to using the clutch as there is no IC engine that will stall if the clutch is not pulled.5) Yes, I do feel a lot more like driving a conventional motorcycle rather than using a conventional EV with a fixed speed gear ratio in the final reduction drive. And it also helps in extending the battery life under varying loads.Once again thanks for your time and interest and I hope that I have answered all your queries.

Thanks a million

Thanks a million bro...

Thank you so much for warm appreciation

Motor is 1200watt e rikshaw BLDC motor 48v and rpm no load is 3300. Batteries is lifepo4 32650 cells with 15s 6p configuration with 60Amp BMS

thank you so much for warm appreciation

Ya it was very time consuming to make this project. Thanks for appreciation

Thank you for warm word of appreciation 👍

Thank you for warm word of appreciation

I forgot to mention you the top speed it is 55kmph and definitely lead acid batteries are heavy but cheap for prototype as well so I used those batteries. This scooter gives me ample of power and range of about 45kmpc so I think it's quiet respectable figure.Thanks for your time and interest 😊🙏✌️👍

First of all thanks for warm appreciation. My second bajaj boxer is almost ready and I am going to use lifepo4 battery pack home made in that. Now getting battery pack is not that expensive as before and things are going to ease off more in India for getting your hands on to some batteries for your DIY EV projects. My channel is techtube360 on YouTube stay tuned for more. Feel free for any help

Ya soon I am going to install LFP in this build and expected range is about to go up by almost 60% Will try putting that instructable here. Thanks for appreciation.

Keep this power bank charged and always keep the switch on while charging and switch off after charging so that it will keep holding the charge for much longer without getting discharged or self drained.

Thanks for appreciation bro 👍

Thanks for appreciation bro..

Mind = blown..I loved this project... Great 👍👍👍👍

You deserve to be a grand prize winner of epilog x contest hats off to your creativity and putting things together. Simply great.

HiDo you mean to say that the batteries will get damaged if I don't use this shielding plate? So far so good there are no problems with my power bank. More so what you have mentioned is not incorrect at all but the transmitter in the power bank is having the ferrite core and receiver does not have as it will soak all the energy transmitted from the TX board. More so the TX does not even trigger till the compatible receiver is not paced. Also, I have tested that the TX board is having the ferrite core does not allow the radiation of power to be in reverse direction towards batteries, so bro your suggestion is worth noting but my design does not have any flaw as of now specifically of what you pointed out. Thanks for your interest and time to evaluate my work. :)

Tell me how can I help you and what kind of project you are looking for ?

Thanks, Actually, I forgot to mention this part, if someone wants to use older devices to charge wirelessly with this wireless power bank.Regardsshalbk

Thanks for your interest. Have a great day.

Thank you :)

Thank you so much for your kind words of appreciation .....thanks once again..

Sir imaginary species of engineers is as like this jumping robot sparrow, and this is no different as its not made by God but man-made ha ha ha...

Thanks you :)

:)

Thanks for appreciation....

Thanks a lot .... For appreciation..

Thanks for your appreciation. Actually what you mentioned was my idea initially but I did not want that the hosepipe to be trailing in from top of the lamp or from sides but what you said will definitely simplify the design and also eliminate any leaks. Once again thanks for your interest and time ...

thank you so much ...

Thanks bro.
