Would like to know if anyone makes a right side drive or duel side drive small engine to fit in a bicycle. Anyone with casting skills out there. Or aluminum duel side drive. I want to run my motor to crank on my bike without having to purchase a shift t kit.
 
whole engine huh?

gimme 2k up front and another 2k upon completion :)

suddenly a shift kit looks cheap.
 
You don't know how to cast some aluminum cans into a block. $5.00 in materials. I was inquiring. Want to know why none of you lames ain't on it with your almighty intelligence. I don't need smart ignant responses. Maybe someone will actually make them for the bike world or whatever application it could be used for. If I had the tools and materials I would be crankin them out for less than the China motors. Shift kits are lame.
 
$5 in materials and hundreds of hours designing a whole damn engine. work isn't free you ****
 
Staton Inc makes a pedal axle kit that allows you to power your pedal axle and then use whatever gearing your bike already has. I'm sure other kits are available from other companies too.
 
Yes thank you. I know this. I was inquiring an maybe just maybe someone would actually make a motor that's quality made for a bike.my point is those motor kits weren't originally designed for bicycles, and they are not quality,and you have to pay 200 for shift kit. Motor kit costs 130. Where is the logic there.
 
I know it can be frustrating trying to find what you want and need to achieve the ride you want. We all face these same problems and compromises. To build a quality reliable MAB it will end up costing far more than you would expect. Fortunately it can be done incrementally.

We need to keep in mind that we all pass bicycles daily that cost over $5,000 so to expect that we can purchase reliable, dependable MAB's with the ability to go 40mph on the flats and climb steep hills with ease with little maintenance for less than $300, might be unrealistic. I'm sure I already have a grand or more in my MAB and it's still not finished yet. But it's easy to spend that on a laptop, on a camera, on golf clubs, a big screen TV system and on and on. It's a bit like buying a gun. You can buy a cheap gun for a couple hundred dollars or you can buy a gun that you can bet your life on for a couple thousand dollars. What's your life worth? Im fond of my Kimber.

What makes you think us Lameo's haven't made a right side drive?

my point is...

and they are not quality,

As far as quality goes $50 makes a big difference.
Try a ~$170 real Skyhawk GT5 sometime.

But not designed for a bicycle?

These 2-stroke engines are designed SPECIFICALLY for bicycles so you can drop it in the bike frame and power your bike from the left side and not have to mess with the bottom bracket pedal assembly.

Right side clockwise rotation engines are not the issue or main cost Ra.
I build electric bikes with right side output motors all the time.


It is the engineering to get 2 vastly different rotational power systems, your legs attached to cranks and an engine, to share a common output without interfering with each other.

There are numerous designs for how to do this dating back to Leonardo Da Vinci.
When it comes to engines and pedals it is all about Freewheel bearings.

Your socket wrench has a freewheel ratchet in it that works the same way, it just doesn't have bearings to support a spinning shaft too.

Picture your socket wrench as a pedal arm but the socket on it has 2 sprockets, one goes to the back wheel, one to the engine.

Just like when you spin a socket by hand when it's easy the wrench arm does not move, it just ticks freely.

Turn the wrench and the socket turns which means the engine sprocket now turns.
Another freewheel ratchet is needed on the engine output, most use a freewheel ratcheting sprocket.

I hope that helps you understand how the interface works as that is the 'magic' part, not getting a spinning direct output shaft right over the pedal sprockets, I do that now.

The real trick is what to use for each ratchet bearing.
