Double Drivetrain Fixed Gear - 2x Freewheels

  • เผยแพร่เมื่อ 21 ม.ค. 2023
  • So I had this random idea the other day, it was to fit two drivetrains on two freewheels to see if it turned fixed. I had no idea if it would work or not but was keen to try it out anyway. Turns out it works! It looks weird, weighs more and is noisier, so no real benefits but an interesting experiment for me nonetheless. Let me know if any of you have ever done this!

      How many freewheels have you broken?
      The most complicated thing about a single speed freewheel is all those tiny balls. It's not a very complex mechanism, nor problematic. Mine are reliable in all sorts of muddy abuse.
      Unless you ride off-road lots, (I do) an FG cog OR freewheel rarely fails or requires much attention.
      Cheap Chinese freewheels are worthless. They are certainly unreliable. Buy at least an inexpensive Shimano freewheel. White Industries makes probably the best freewheel on earth. It will last at least 10 years of hardcore abuse. My Dos Eno FW is a great investment.

Somebody was telling me in my thread I could do exactly like you did, or to some degree, and your build is pretty cool; a free wheel fixie. You actually helped me out on a number of things, for when I can get around to it, 1; I hadn't considered the fact I'd need two rh pedals(surprisingly), 2; that I could use a regular flip flop hub, I thought I'd need this specific BMX hub I found, when I discovered that in the 90s there was a twin drive BMX bike. You just made it easier for me when I can get around to building mine, won't be fixie, but will still be awesome.

    Funny idea! :D you can use different gear ratios on both sides. so pedaling backward would have easier gear or other way around.. maybe for climbing up hills backward.
    Or.. left side could have higher gear for braking on longer hills.

    • @waveywheelies
      @waveywheelies  ปีที่แล้ว +1

      I did briefly think of different ratios, but my thoughts were that it might not work. If the LH side was a lower ratio (easier gear) the LH side would want to drive the cranks faster foward that the right side potentially causing some issue or weird chain tensions. Not 100% sure but would have to try it out and see!

      Lots of track racers would disagree. A fixed gear may not be practical for your style of riding.
      I love mine. I've got a dozen custom built bikes. MTBs, 'cross/gravel bikes, SS 'cross and rigid SS MTB. A monster cross, loaded touring, bike packing and road race bikes. All built by me for a purpose. My 'Crossafix' is my favorite most used bike out of all of them.
      In fact, youre not allowed to ride on a velodrome without fixed gear or with brakes installed.So there is indeed a legit purpose for fixed gear.
      I'm skeptical about a double drivetrain set up compared to fixed. It's not mechanically logical, cool tinkering is pretty fun though. But I'll reserve my judgement until I've tried this out.
      To all those who've never ridden a fixed gear, (or SS) try it out first before you hate on it. Then you'll have some real world experience.
      Sure, fixing certainly is not suited for everyone. You're going to need to learn to suffer and find new personal limits. This is what improvement requires. Learning to push yourself, exceeding your limits, Suffering and recovery is what going faster on bicycles is ALL about.
      Same goes for SS. Lots of folks critisize SS but will never EVER try to ride one. 'It's gotta be just impossible!' So they never even try! They're just too lazy. And that's OK! To each his/her own. But Talk about the power of positive thinking.... To declare something's impossible but never even make an attempt?
      A fixed gear is more mechanically efficient. More efficient regarding input and output. There's less energy lost thru drivetrain loss. There's also energy stored in the inertia of the spinning wheels and drivetrain in motion. But you'd never realize it until you experienced it and actually tried.
      Fixed gear is as simple and most reliable mechanically as it gets. Far less moving parts to fail or maintain on a fixed gear. Its by far the most affordable drivetrain. It's tried, true and proven for well over a century.
      A fixed gear will very naturally and automatically FORCE you to learn to pedal CORRECTLY, in circles. The French have a word for this, 'souplesse'. THIS is what makes fixing an excellent training tool.
      A fixed gear will build leg muscles you never knew you had, also builds extra stamina and explosiveness in acceleration.
      A fixed gear is a more efficient workout (you work harder in a shorter amount of time) and will keep you warmer in winter due to pedaling always. Pedaling always has lots of interesting benefits. When you force yourself out of your comfort zone, you get a training effect and get stronger with improved skills.
      A fixed gear allows you to control speed and sense traction through your feet. The bicycle literally becomes an extension of your body if you're using pedal retention.
      I ride a fixed gear cyclocross bike off-road all winter, every winter and for everyday commuting, training and local trails. I can ride it in mountains and in technical rocky singletrack. I do fixed gear centuries every year and I'm 61 years young.
      Lots of pro roadies trained fixed in the winter back in the day. I trained for road racing with fixed gears for many years.
      Fixed gear off-road is more fun than should be legal. It makes me feel like a little kid again.
      The very most difficult thing about riding SS, is conquering your fear and the negativity of your mind. Stop the 'I can't' mindset. The question is 'DO or don't?' Not 'can or can't'. It's actually an incredibly simple problem to solve, it's just not 'easy'. Nothing truly good truly comes easy....

While at reverse crank chain ring make 1 rotation, freewheel make 1 rotations, wheel itself make 1 rotation AND reversed forward freewheel makes 2 rotations(it wont engage because wheel is slower than it). And when we try to pedal forward. Chain ring try to make 1 rotation, freewheel tries to make 2 rotations and wheel itself is trying to do 2 rotations AND THEY CANT because they are stopped by slow freewheel that is doing only 1 rotation just like the chain ring itself. Its going to get stuck on itself because wheel cant go faster than reversing low gear ratio. Oh what a BRAIN EXERCISE!

    You can do this entire thing in a single pedal axis- without the additional chain. Each pedal would be directly engaged with a freewheel which then would engage with the chained sprocket to a fixed sprocket on the wheel

    With three freewheels you'll get forward reverse and neutral (neutral is when two of three line up in the reverse direction of the other, so it works in both directions - technically you get *two* "neutrals" but since they're both neutral it seems like one).
    You could also use a *unicycle* geared hub, which has freewheel/lock options as well as heel operated gear shift options.

  • @floppycheese96
    @floppycheese96 ปีที่แล้ว +9

    you should try to make the reverse freewheel a lower gear ratio than the forward one, you'd be able to reach higher top speeds while being able to skid more easily (or am I wrong? this is all mental anyway haha)

    • @DaBinChe
      @DaBinChe ปีที่แล้ว +1

      That is correct...main thing to figure out would be chain tension. You'll have to fine gear ratios that have the same chain tension or very close cause different gear ratios will have different axle to bb distance.

    • @Eduardo_Espinoza
      @Eduardo_Espinoza ปีที่แล้ว

      I wonder if a math formula could be made to find the distance between the center of the 2 cog/chainring. 🤔
      Maybe we can generalize that similar ones are slack & vise versa

    • @waveywheelies
      @waveywheelies  ปีที่แล้ว +3

      I did briefly think of this but wasn’t sure it would work, my thoughts were that if the LH ratio was lower the LH free wheel would want to rotate faster foward than the RH side, causing some kind of issue, so I’m not sure the chain tensions would work. Maybe I should try it out and see

  • @robertrjm8115
    @robertrjm8115 ปีที่แล้ว +1

    one problem you might face in the longer run is that the left pedal might be come unscrewed since it now has the wrong thread direction for the non drive side. This is a common problem on unicycles when riders don't watch out and always use the same side to go forward. (the saddle can be rotated by 180 deg and hence it is not always immediately obvious which is the correct direction) .

    Double chain bike could be a good idea for making the bike walking front or backwards, depending the way the pedals are moved. Interesting idea for mounting a bike for rail track configuration.

  • @stuarthibberd6549
    @stuarthibberd6549 ปีที่แล้ว

    Have people never considered why we have left and right threads on pedals. The reason they are like that is so that if the pedal bearing locks up then the pedal will unwind on its thread while you are pedaling forwards. So to say that the left hand pedal will gradually come loose is incorrect as any binding in the axle will cause it to tighten not loosen. If anything the right hand pedal should loosen!
    So on a normal bike both pedals should gradually come undone but this will only happen if an axle binds up so consider this as a safety feature built into your bike.
    Next time you take off a pedal hold your peddle spanner horizontal and rotate the crank in the forward direction using the spanner and surprise surprise your pedal will come off.

    As an engineer, i like the symmetrical loading of the drivetrain... That this is sadly missing out on because of the freewheels 😂 jokes aside, different gearing for backwards and forwards would actually be interesting. Maybe you can find a cog large enough that it compensates the 2 added links exactly so the rear wheel is in straight?

    • @rollinrat4850
      @rollinrat4850 ปีที่แล้ว +1

      This set up is actually significantly less efficient for very little logical reason. IMO. Unless you just ride backwards 1/2 the day, maybe.
      I can ride backwards on a fixed gear a little bit, (that's actually MORE efficient) but looking where I'm going is much more efficient when I'm just trying to get where I'm going.
      Bicycles were intended to be efficient affordable transportation. That's the role they fit the best.
