Before worrying about helicoil, just re-thread with left-hand tap and see what you get. Chances are better than not that you'll have enough threads for secure pedal torque. A framebuilder friend did this multiple times to make left-hand tandem cranks with no issues whatsoever.

[@ItsDaJax]

So that means you probably ran across some post I made about doing a dual chain bike, a few years ago on either BikeForums or RatRodBikes. I still want to build one. 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.

[@ThisTimeTheWorld]

If you put a crank arm on the wrong side, be sure to threadlock or tack weld the pedal spindle, or it may unscrew while riding. You can weld a small nut to the crank if it's steel, and install a grub screw to keep the pedal spindle.

[@miguelemsYT]

You sir, are a gentleman and a scholar.

[@Rafskat]

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]

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!

[@michaelallan108]

Getting chain length and tension might be tricky but in theory a chain tensioner on the RHS, or even wilder the top of the LHS might work?! Please do this!

[@VyantQuijt]

@@waveywheelies since either side is always freewheeling you shouldn't have any problems running different gear ratios, as long as you sort the chain tension. A tiny chainring and massive freewheel on the left would translate to high leverage on the wheel for very low effort, easy on the knees braking.

[@samsonsclan7439]

​@@VyantQuijt Right 52-16 Left 52-24 are they going to work ?

[@VyantQuijt]

@@samsonsclan7439 I wouldn't know, man. I was thinking more along the lines of a 1:1 ratio on the left for the braking. Only concern for chain tension is that the sprocket centre distance for either of your selected ratios is near enough the same, so you don't end up with one overly tight or slack chain. I'm sure there's some calculators for that online

[@pinchflat]

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]

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]

@DaBinChe 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

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

@@jonasmeiner5007 the chain doesn't need to be perfectly tight, you can get it about right with a little luck by taking links out of the chain, and trying different combos of gears.

[@MTBkid42]

I wonder what a mixed ratio setup would do. Maybe let you have different ratios forward vs backwards?

[@sechsnine4556]

I guess it would block itself or snap a chain. Reversing wheel itself engage any freewheel. Lets say forward ratio is 2:1 and reverse is 1:1 ratio. Going forward is then impossible. 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!

[@aaroncarmichael8263]

Looks good, that's all that matters at the end of the day

[@andreyisakov1811]

An interesting experiment. The left pedal will definitely twist off the connecting rod during the trip.

[@robertrjm8115]

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) .

[@waveywheelies]

Yep definitely! Interesting about the unicycle, never thought of that

[@macwacs]

EXCITED TO MAKE THIS FROM SCRAP THANK YOU

[@altus1226]

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

[@buffalomind6838]

What are the advantages to setting the bike up like this? I would think one gets either much more difficulty peddling, or half the effort with faster speeds.

[@keit273]

since there are two chains, the forces the chains see are distributed among two chains so in theory, it will take 2x longer before you need to replace the chain.

[@benallgeier5932]

There aren't any really, he just did it for fun to see if it was possible.

[@longdang2681]

I've thought of a small advantage is that you can use the unidirectional halflink chains on both sides which means that you can use a smaller rear sprocket(s). This can give you a higher gear ratio when you are limited in front cog size or able to use a smaller front cog for the same gear ratio.

[@russellzauner]

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.

[@bmxscape]

wow there are geared unicycle hubs? that is sick

[@bmxscape]

a bicycle chain drive is something like 95-98% efficient meaning tere is 2-5% loss of energy in the system. the more chains and sprockets you add the more energy is lost. although in this case the 2nd chain is freewheeling so its not actually doing much

@@waveywheelies if the left side freewheel was smaller, it would just freewheel faster than the right. if it was larger, it would freewheel slower than the wheel is spinning therefore would just jam up the whole system and nothing would spin. which means if the left side is smaller, it will jam up the system when going in reverse as the freewheeling gear is now the right gear and is now larger. so it doesn't work with any ratio other than identical on each side
