Eliminate the speed limiter on any EBike – Full tutorial

Eliminate the speed limiter on any EBike – Full tutorial

In this video I show how a simple pulse generator can be used to fool an EBike speed sensor so that it no longer has a speed limitation. Feel free to EMail or comment with questions.

The parts are as follows:

    Buddha! That is too much for me. Better just get a naturally faster bike.

  2. If you own an ebike like me then you spent loads so why not just buy the real chip that goes on to the motor wires that you can turn of and on , 100 pound ish

  3. "I said hold up wait a minute,something aint right "


  5. Cant one just install the magnetic sensor closer to the rim, thus making the computer think you are traveling at lower speed?……I don’t do computer’

  7. total waste of time

  8. Why not just re-route power from life support, thereby increasing output from the dilithium crystals?

  9. Can you recommend a bolt on set up that is comparable to or better than Paradox kinetics full back pack 2,650 system. Plz and ty.

  10. If only I never had constantly played with my dozens and dozens of lead toy soldiers which used to have most of the paint worn off as a kid , I might have been able do this for my Bike :))

    F%@# this

  12. or you can just remove the speed limiter wire on the controller

  13. You’re… You’re using a knife to cut the electrical tape… electrical tape can just be snapped right off really quick.

  14. Has to be an easier way. Maybe just buy a new controller.

  15. This guy is a moron, there are easier hacks than this , this idiot needs to stick to making antennas

  16. Alex grieves is a fucking moron.

  17. Nice, but this works not on any ebike …

  18. 300 Swords of light February 1, 2021 @ 8:30 pm

    Does this also apply for Specialized Turbo X hub motor?

  19. Could you use heat shrink instead of tape on the coil?

  20. This doe snot work on newer bike with the speed sensor in the hub like my iGo Discovery Atwater

  21. Yeah i consider myself pretty intelligent but I didn’t understand a thing he said haha.

  22. WTF has time for ALL that crap

  23. lol..I thought I recognized my dude IBcrazy from my fpv days 馃檪

  24. Positive Warrior February 1, 2021 @ 8:35 pm

    This might be good for an intermediate hobbyist to build however it takes and advanced hobbyists to understand this tutorial.

  25. Orlando Gonzalez February 1, 2021 @ 8:37 pm

    Wow I am completely lost.

  26. Likes go hear his own voice utter bollocks this stuff.

  27. Wtf is this imma Get my master Degree

  28. Tf is this mate?

  29. Vhaleryan Adamant February 1, 2021 @ 8:44 pm

    K bye

  30. No need for that… Just move the sensor on the frame outsite and attach it with a cable tie, put a magnet on the pedal innerside where the sensor is attached to the frame and your good to go. The Sensor now messures the turning of the crank. No soldering, no battery an Maximum speed馃か

  31. S茅bastien Fraggl February 1, 2021 @ 8:47 pm

    why not just changing the controller ?

  32. Mango Paving & Landscaping Ltd February 1, 2021 @ 8:48 pm

    Is this guy serious ?

  33. It doesn’t work on a giant quick-e, I even ordered the PCB from china(the board cost $3.00 but the shipping, duty and taxes are $50.00) and it doesn’t work. Lol

  34. Can you start up a business selling these kits please

  35. is that dog poo on the tire ?

  36. Yeah, you will burn-out your components and wear your tires, brakes and battery. You gotta’ sacrifice more than you your equipment can handle, in this case…

  37. How can I use the throttle, it is not coupled for Belgium. And use my Dohiker as a moped. Please advice. Thanks, Erik.

  38. Couple, few questions. Is this solution limitted to mid dr ive, how do we modify cadence sensor? Just put this in place of magnets?
    How is action of controlling bike, with continuing pulses telling motor to keep accelerating faster and faster, how does this effect normal riding? Should we power the pulse generator from signal of cadence and/or brake cut off switches? Is it possible to burn up motor windings and/or controller?

  39. 馃憤馃憣

  40. Hmmmm ok you make it look so simple could you just make me one for a juiced ripcurrent s. Thank you

  41. I accidentally disabled the throttle on My himiwaybike when I increased the petal assistance from 0/5 to 09 . Now it only has
    petal assistance from #3 & up .
    When the bike is in garage throttle
    moves bike from #1 thru #9 .
    How do I turn throttle back on ?

  42. Are you kidding me? I wouldn’t be able to change the tire & you expect me to be able to be a electrical engineer?

  43. Shainexxxse Scrimshaw February 1, 2021 @ 9:00 pm

    In what universe can an intermediate school be cyclist hobbiest do this

  44. Never tough of the wheel balance because of the reflectors… Removing them in 3,2,1…

  45. No Money Production February 1, 2021 @ 9:02 pm

    I can’t even spell Elektrick, what chance have I got of de-restrickting my bike

  46. I just bought an EM! daymak used and I only noticed later that the box was missing under the seat ,now it wont work properly ,it dies after 1 klm.I am lost. I got screwed by the seller and I was too in a hurry to buy it ,shame on me too.

  47. there was a grandma with dogs and flowers speeding past me. I am sure she hacked her ebike to go faster.

  48. Can someone just make this a kit and I’ll buy it? Hahaha. If not I guess I can if I pull it off

  49. I’m definitely not against faster ebikes bikes, but my biggest concern with a mod like this is brakes. The disc brakes, at least on the bikes I’ve had, just do not have the same stopping power as vechicles that are actually designed to go this speed. Worse still, unlike motorcyclists a lot of people own these bikes without any training, and don’t understand how to best use their brakes. Locking up your wheels at 40mph is a recipe for a bad, bad time.
