    Just roll up your pants before you ride it

    what size engine is on it?

  5. Thrashaero on July 24, 2022 at 10:54 pm

    Forgive my noobish ignorance but why not skip the entire jackshaft kit bs and just use the bottom bracket/ crank as the jackshaft by putting large drive sprocket on left side, to just go straight down from motor sprocket and leaving the stock right crank in tact?’

    In other words, just like stock engine drive setup except output sprocket moved forward from left side of rear wheel to left pedal. Would seem a lot lighter and less complicated other than having to replace left crank arm, (which you’re already doing to the right side otherwise). What restrictions are there??

    the hole in the gear is threaded for a set screw. it would stay on and you could get rid of that hose clamp

    Your shift kit is also chinese

  8. William Jenks on July 24, 2022 at 10:56 pm

    My masterlink keeps falling off

  9. Busted Tech on July 24, 2022 at 10:58 pm

    Dude your piston head is on wrong. The fins are soposed to be parallel with the wind. The wind flows through the fins and cools your engine

  10. Rashad Abdullah on July 24, 2022 at 10:59 pm

    Pretty cool

  11. Joel Sanford on July 24, 2022 at 11:01 pm

    I see BMW has had a major influence on your ability to overcomplicate things for worse reliability 😂

  12. dirtyvarmint on July 24, 2022 at 11:01 pm

    I’m not an engineer but it seems like the shift-kits are way over-engineered and redundant. Just install a sprocket on the left side of your crank. Problem solved. You only need 1 part.

    The PTO would turn a gear with a chain going down to your left-sprocket. This would turn your crank and allow you to switch gears. No need for all those extra chains and sprockets and mounting hardware. Why go around the back of your seat post when you can go directly to your crank?

    I think i would die if i put a shift kit on mine🤣 without disk breaks i just stick my foot in the back tire LOL

  14. Stone free on July 24, 2022 at 11:04 pm

    Why have a shift kit if your only gonna go 15 mph ????????
    Get rid of that crap pull starter .
    Buy two leg kick stand.
    Use pedal to kick start bike.
    Class dismissed.

  15. Bowlsnapper on July 24, 2022 at 11:07 pm

    You didn’t shift. Damn you.

  16. Edward Vela on July 24, 2022 at 11:07 pm

    I always buy 2 of everything. Sometimes you just have to experiment.

  17. Moppy Yt on July 24, 2022 at 11:08 pm

    Bro no what are ya doin, you got the head on the wrong way

  18. David Phillips on July 24, 2022 at 11:09 pm

    keep up the good work bud. building is the best part of this hobby. Just a tip from my build, I re positioned the drive chain behind the bike chain and the chains didn’t collide anymore for me. Be safe, bike life!

  19. Sherloc Bum on July 24, 2022 at 11:10 pm

    That back wheel ain’t gonna last I went thru eight of them

    Ganhou mais um escrito se pode retribuir Tmj 👍👍👍

    I haven’t used any of the motorized bikes I have in years but I have many different types of styles of bicycle all the same engine I chose from China’s wondfrom china there’s one that’s I feel 1 of the better ones but anyway the speed is what hurts the stock chain I was eating up chain left and right have a friend that builds bicycles and got bills bicycles and got me a bag of master links but they break because of the tension on 1 of my bikes ago over 55 . But then you’re burning up the barrens and the wheels of the tires cause they’re not made for that kind of speed

  22. Galindez DIY / PROJECTS on July 24, 2022 at 11:16 pm

    how fast is that

  23. Build-Break-Fix on July 24, 2022 at 11:18 pm

    First and last name please? I want to buy an insurance policy before it’s to late LOL! Looks like fun build!

  24. Gibran Ramadhan s. on July 24, 2022 at 11:18 pm

    The video I’m looking for about a bicycle engine that uses gears is just you are very good

  25. Steven Ferretti on July 24, 2022 at 11:20 pm

    This may seem like a dumb question but why do people put on shift kits? Does it go faster?

  26. Ernesto Arizpe on July 24, 2022 at 11:20 pm

    Shifter kit puts too much strain on the thin pedal chain

  27. linkgroundwalker on July 24, 2022 at 11:21 pm

    Any reason everyone installs their head sideways? The cooling fins should be with the direction of the wind so you get more air passing through them. Sideways I can’t see you get any, it would hit the fin and turbulence would make it go haywire and you wouldn’t have as efficient cooling.

  28. Daniel Walsh on July 24, 2022 at 11:23 pm

    That’s a perfect example of how to complicate the hell out of something that’s very straightforward and what’s with the parts of washers the hose clamp and everything else when that stuff let’s go and all those bits and pieces are binding up against each other and like your whole Driveline just seizes up in one instant you’re going to be one hurting unit take all that stuff off and save your life

  29. Wylde-man Zakk on July 24, 2022 at 11:24 pm

    Why did you even put that pull starter kit on it? Cause when you put that kit on it, it becomes a kick started motor on a bicycle. I’d like to like to say is a MMB motorized mountain bike.

  30. dirtyvarmint on July 24, 2022 at 11:24 pm

    does the shift kit still work right if you have a kick brake?

  31. White Trash Bandit270 on July 24, 2022 at 11:27 pm

    I’m about to put an engine on mine.. but it doesn’t have multiple gears on the outside and a derailer .. the gears are all in the hub.

  32. Lloyd Franks on July 24, 2022 at 11:27 pm

    why don’t you make a chain guard

  33. Bene 03 on July 24, 2022 at 11:29 pm

    Da hora

  34. Bilinti on July 24, 2022 at 11:32 pm

    how about BMW? 🙂

  35. Iam Ulfr on July 24, 2022 at 11:34 pm

    I had bought one of sick bike parts kit and ended up throwing it away cause it didn’t work right on the motor and bike I had at the time.

  36. DjoDjo Dubois on July 24, 2022 at 11:35 pm

    Ouais mais..ton pédalié doi tourné quand ton moteur tourne..??quoi tu te lève les pied dans air.?

  37. Note Guy on July 24, 2022 at 11:35 pm

    Great explanation though as I didn’t know anything about it either and went through a have always been good at tinkering on 2 strokes got that thing mean in the engine to really run when you change the car braiders the 1st thing and intake just like on anything for 2 stroke you put a different pipe on it that makes one heck of a difference after you get a good carb for it and it has a good intake The engine kit suck my horse I can’t remember the full name Crazy Horse I don’t remember but anyway that is I feel the best set up for the generic setup engine compared to that other stuff they’re making now

  38. David Stout on July 24, 2022 at 11:36 pm

    Do the pedals rotate the hole time

  39. Crispified98 on July 24, 2022 at 11:37 pm

    please get a new exauhst

  40. gta5grindz xb1 on July 24, 2022 at 11:37 pm

    Quick tip if you’re not using it already, rubber fuel grade hose and clamps. Doesn’t fail as easy as plastic. Check with NAPA auto parts they sell it by the foot and its fairly cheap. Same place for clamps.

  41. Pelican on July 24, 2022 at 11:39 pm

    how long does the chain last if you are hard or soft on the throttle?

  42. John Kempf on July 24, 2022 at 11:39 pm

    Your head is on wrong. WTF?

  43. viewRBware on July 24, 2022 at 11:40 pm

    What an abortion you got there…. TOTAL DISASTER.

  44. William Jenks on July 24, 2022 at 11:40 pm

    Just use a impact power drill to start it

  45. William Jenks on July 24, 2022 at 11:41 pm

    People think a fair price constitutes false advertising

  46. Jean Lawson on July 24, 2022 at 11:43 pm

    The set stew can be purchased most large hardware store

  47. DjoDjo Dubois on July 24, 2022 at 11:45 pm

    Je veux voir ton pédalié quand ton moteur tourne..pcq si ton pédalié tourne tout le temp sa donne complètement rien..apport ce blessé ses que ton pédalié faudrais qu il face du sur place quand le moteur tourne..

  48. Marcellolaranga Larangeira on July 24, 2022 at 11:46 pm

    Congratulations on the Bike

  49. E.R.T. on July 24, 2022 at 11:47 pm

    Love that bmw 🦾
