    With the motor off and clutch disengaged, my motorbike is still tough to pedal.
    (Road conditions in my area sometimes dictate that I pedal down the sidewalk or multi path for a spell, and I regularly ride unassisted bikes anyway)
    If I loosen the star nut enough for easy pedaling, the clutch tends to slip under engine power.
    That big chain makes a lot of drag too.

    I am trying to devise a way to allow my rear wheel sprocket to freewheel for easier pedalling when desired.
    I don't need a clutch system on the rear sprocket that will allow me to engage and disengage on the fly. A mechanical quick release that requires me to stop would be fine. In fact, I dont really need to use compression braking.

    I know there are some pricey ways to accomplish this. Anybody got any cheap solutions?

    I used to pop the master link and remove the drive chain when ever I had to pedal
    only takes a couple of mins to re-attach after you do it enough times

    Jackshaft shift kit would do it.

    You could change the size of your peddal sprocket to make it easier to peddal.

    Azbill's method is good and cheap but I get my hands greasy doing that.
    I thought of just releasing the chain tensioner, derrailing the chain and hanging the chain on something (without breaking it) to keep it away from the sprocket. I would get greasy doing that also.

    Cabin - I did try regearing and it made for some slow going.

    Dan - I had forgotten about the HybriPed - That's an affordable answer

    Nougat - the SBP jackshaft allows you to pedal without spinning the engine drive sprocket? How does it do that? If so, I might go with that and eliminate the motor chain if it looks like the lawmen in Ft Bend county are tolerant of gas assisted bikes on their roads.

    I have not yet ridden my motor bike in TX, but I will be getting it out of storage in a couple of weeks.

    Are there any reviews of that sprocket yet WB? I haven't seen any and am really curious.

    I actually use Bill's method. With testing prototypes, I now carry every tool you would need to build a MB. Along with a plastic bag and exam gloves because there is nothing greasy like drive chain grease, snork. Even worse, I use bacon grease and after it is warmed, becomes very thin. But only remove the chain for break downs.

    Side note, bacon grease is the best rusty bicycle chain restorer I have ever found. Makes em look brand new. After it has been on 12 hrs or so it just seeps in and makes em beautiful.

    I know you're mad at me Dan but I have to reply to your post & say that thing seems really nice. I wonder how they hold up under many miles of use?

    Am wondering too Jay. Seems like a whole lotta torque to be placed on 2 bolts. Might start a thread and ask if any one has tried it. I really like it's simplicity. Another question I have is seems the width might be an issue.

    Not in any way speaking badly of a product I don't have first hand knowledge of, just wondering. Solves the problem perfectly. I hate having to pedal to the gas station or home with the drive chain. lol

    Yes. When any of my bikes run out of gas( yes it's happened to me a few times) they don't pedal easy. I'm a little uneasy about 2 studs doing the job, but I sure hope this works. I'll be the first to buy a couple sets. The price is reasonable too.

    I might be a little off the angle of thought. But I thought I might mention that I recently replaced my rear wheel assembly as a result of impact damage. I chose to upgrade to a brake disc hub that has allowed a direct bolt on 38T sproket (no spacers or adaptors or "top hats" required, still using v-brake for stopping). An unintended side effect of the zero run-out set-up of the rear sproket has reduced pedaling effort an unbelievable amount.

    Awesome Sal. Off angle is applauded! Please elaborate. Pics if possible. Sounds great

    The top speed the hybrid sprocket supports is only 25mph. I wouldn't feel safe long tern with the 2 bolts.

    what about 4 doesn't look like it would be that hard to mod?

    Like jumping out of a good airplane, why do you want to pedal a perfactly good motorbike? I think I would just walk it on a walking path like I do the sidewalks around here.

    Great catch Catfish. Had not seen that, thanks.

    Bummer though. Really liked the idea
