  1. Any tips on how to read the specs sheet of a bike to understand which gears are available? I want to know the maximum ratio and minimum ratio before buying a new bike

    Thanks one of the best explaining gears videos.
    Silly question: you mentioned the high gear front with low at rear is easiest way to climb a hill or going from stand.
    When then we need the front low gear?
    I am going to get a hybrid bike that may have double gears in the chainset.

  3. Like

  4. they look like this, or this
    My bike that looks nothing like that: nervous sweating

  5. I pulled a stupid and thought the small gear was 1st gear, needless to say I was very tired

  6. 1:02 what is it?


  8. Thanks, Bro because I don’t know how to use gear in a bicycle than whenm I SAW THIS VIDEO IT WAS EASY TO UNDERSTAND IT THANKYOU

  9. The slower pace of this explanation compared to other videos helped my thick brain understand this 🤓 Thanks!

    Sexy dude 🤤

  11. How did you dub in Moss’s voice so perfectly??

  12. Ararat Qarachatani December 12, 2020 @ 9:31 pm

    Thank you

  13. The video was really good until it ended. I was hoping there was illustration of few combinations

  14. This music has no business being this groovy

  15. Give this fucker a cookie!! Thank you man, finally I get it! I love you Bro!!!!

  16. Very nice explanation

  17. tysm

  18. what is good cheap MTB use for everyday travel to work..ineed mTB but dont have much budget to buy branded MTb..
    because of this covid MTB is so important for means of travel

  19. Love from my heart

  20. I paid $3000 usd for carbon frame bike from Hung Fu Sports Equipment Co. Ltd. The bike came first day with damages. Paint came off and carbon fibres exposed. Jenny and Eric denied the responsibility and told me to accept the bike. I will not buy from China again. Very dishonest Chinese merchants in China.

  21. Very clear and informative video, thanks for uploading!

  22. Reeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

  23. Thanks for planning the ratio! Got it!!

    However, the way you showed it is confusing… 11 + 50 = 4.55 makes no sense.
    However, if you show it this way 11:50 > 1:4.55 that would lineup with what’s being said & make more sense.

    GooooooooooD Job

  25. Very informative!

  26. David Bettencourt December 12, 2020 @ 9:51 pm



  28. Very informative keep and good videos and explanations

  29. This was a fantastic video, thank you! Quite informative paired with the visuals, it was very helpful as I had no clue about what cassettes and how they work.

  30. #theboredgoddess14 December 12, 2020 @ 9:54 pm

    i needed this for an assignment due tmr and it had a question about gears and this helped soooooooooooooooooooooooooo much!!! thanks!!!!!!

  31. Is there any videos you recommend to watch for people who are just getting into mountain biking ?

  32. I like it

  33. it’s very very complicated, normal bikes should just have 3 gears so that less complex mathematical calculations are required.

  34. I got a really cool bike 2 days ago

  35. Wow, this is extremely helpful. Thank you.

  36. Love from my heart

  37. Thanks….I got it in the first time itself

  41. So cutee

  42. Ooo was hoping for the differences between a high gear and low one. What number to choose and when.

  43. ARPIT SINGH THAKUR December 12, 2020 @ 10:14 pm

    Great video. Thank you. 💕💕

  44. Annabelle Joinville December 12, 2020 @ 10:14 pm

    So cutee

  45. I have a 1987 Panasonic 10 speed road bike with Shimano drive train parts, that I want to preserve in its original condition except for the chain. I need to replace the chain and I’d appreciate advice/feedback on what’s the best Shimano chain for this bike…..thanks

  46. Awesome!!! I have been finding it difficult to explain how to change gears to my club members. This video killed it!!

  47. I bet that haircut makes you go faster

  48. Never understood them. Never will.

  49. Good video. Why are bikes called 21, 18 or 11 speed?
