Want to ride an e-bike? No batteries needed! • FRANCE 24 English

1. Why should any fit person get an assisted bike? If you're going up a hill that's what the gears are for.

2. Wow an electric bike without battery it's like that invention already existed 😭😭😭 🙏🙏🙏

3. seriously?? this is revolutionary??😂😮😅

4. I buy lankeleisi e-bike for $600, equiped with 0,72KWH battery that can reach 110km using 50:50 pedal assist LOL, that $2800 E-bike is ridiculous

5. That reminds me of Toyotas ev-disparaging commercial for the self charging car.

   The question remains? Is it just a mild hybrid or can you charge the capacitors from an outlet? And also how much energy is stored in them?

6. Isnt that the original Bike!

7. This is a joke right? Because this is pathetic

8. for 2000 euros ($2100), i can buy two ebikes with good battery capacity and one year membership at a gym.

9. This is actually regression.

10. I've had this idea for ages, FML

11. 2000 Euros for a bicycle?. Meh.

12. 10 gears should fix that problem, old tech, but still good, better lately with higher capacity capacitors😊

13. they got us in the first half

14. I am an engineer, this idea is retarded. On the flat it wont make it easier to pedal, you dont get something for free.

15. In Bulgaria with that amount of money I can commute to work with a TAXI for 2 years.

16. A nice idea but still limited by the laws of energy. lift 500 g 1 meter and you can recover that energy minus some losses , but not gain twice the amount. I think a lightest bike rather than all the extra weight would be my preference. You will recover perhaps half of braking energy, that lost will be replaced by the rider. I like Super capacitors they have no internal resistance just lose potential on the discharge graph very sharply. Sound like a development of illegal Tour de France cheats?

17. why not just use a small battery then instead of super cap?

18. Normally the rare earth metal Tantal is used in every transistor. And gold in the PC parts. So how can you build a PC. Which is the microcontroller of the e bike without it? I think it uses very little rare earth minerals, not none

19. I buyed a normal bike for 400 🎉 And it has no battery 😂

20. Ebikes in our country costing around the same price as a super motorcycle rather invest in a super bike or classic motorcycle Ebikes also expensive to service if the Emotor stops working because it was raining and it has got water in the motor ( common problem anything electrical do not like water )1200$ to replace for a mid range motor

21. Capacitors Faraday

22. is it gender neutral?

23. weaarriy gut baikee

24. For a hybrid car, you have the combustion engine that can propel the car and with that momentum you can generate current to charge.

    But for a bicycle I'm not sure a person can generate significant power to charge the capacitors. Unless we have an extremely efficient generator, athletic rider, and suitable terrain. And even then, the power held by the capacitors will be minimal.

    Not trying to be negative, but in terms of technology we are still not there yet.

25. Supercapacitor batterie is still a battery ….

26. Is that a joke?

27. Le principe de conservation de l'énergie !!! Si on pari sur l énergie musculaire seulement, alors je miserai plus sur un velo carbone et un multiplicateur de couple et voilà. Pas de batterie tt cours. La batterie c ton corps et ton alimentation ton électricité

28. My bike runs on flatulence

29. Are these bikes free to ride ?

30. The very term the bike recharges itself implies that the bike has a battery meatball

31. so basically it's just a concept, they never showed it work. The idea it's interesting as you charge it on the go and don't pollute the environment at the end cycle of the batteries.. however, without an actual demo I would assume it can only push the bike for a short period. It just looks like the main use is for the display on the handle.

32. Big love and huge support of great innovation of our reputed France electric and mechanical engineers .
    God give you more energy to support humanity.
    Again big love from Pakistan .

33. A bike….?

34. I don't get it, you still have a storage just a worse one than batteries and doesn't keep the charge for long, as capacitors tend to lose their charge with time a lot. It would be an idea to have some supercaps working like a KERS-like system supporting the battery pack, but it would be very little energy recuperation. Having them as the main power supply is a dumb idea IMO.

35. So supercapacitors, ie effectively batteries that don’t hold much. I couldn’t say until I tried, but I imagine the only benefit would be leveling out the energy needed to start moving, which seems to give beginner cyclists the most trouble. Otherwise it sounds like extra weight and complexity to hold a miniscule amount of energy.

36. 😂 useless junk how many hours of riding is needed to charge 1 km ride😂. So it's completely useless

37. She says its more environmentally friendly because it doesn't have a lithium battery. But im guessing she has a smartphone, tablet, and other stuff with lithium batteries, but that's ok. SMDH

38. Another green bs.

39. Pioneering 😂
    🤦🏻 It's nothing new. Its called dynamo 😅

    Put a transformer while you're at it 😁… a flywheel at the pedal level… something rly innovative !! 😅
    Put a jar too 😅 and magnetically seal it 😅

    The price… is retarded 🤦🏻
