Cogs for front wheel?

[flantoons]

Hello ,
I would value any advice please.
How can I get 2 freewheel cogs onto a front wheel...one each side of the wheel?
What is the easiest, cheapest way please?

It's an invention to drive the front wheel, not worked out yet.
Regards,
Flantoons

since most (all!) hubs will only take a freewheel/casette on one side only... i doubt there's an easy or cheap way.

Fixed gear/SS bikes often have sprockets on both sides (obviously only one per side, so no multiple gear option), but the spacing would be too wide for a front wheel.

If you did that, you’d have one gear for going forwards, one for going backwards.

Steering on a front-wheel drive bike would be... interesting.

A double sided fixed "rear" wheel would be your best/only option, but (as above) the spacing would be an issue unless you were able to manufacture/bodge the forks

You wouldn’t be able to drive the left-hand sprocket forwards.

You’d only have to boost it from 110mm to 120mm to take a track hub. Might be possible with a steel fork perhaps?

Even if it’s possible it would still be a daft idea though.

Are you looking to power this with a motor?

Simpler and more elegant solution would be to use one of the many electric wheel hub motors available.

Fixed not freewheel?

It would unscrew itself if you tried to drive a fixed sprocket the wrong way. Although you could use a lock ring to prevent that, I suppose - might not be possible in that hub though.

The drive direction is the same on both sides, on the one pictured. Built for a left hand drive.

It shouldn't be too much of a bodge right enough, not sure how a track wheel would work with vertical front forks tho as apposed to horizontal rear

There are already some front-wheel driven recumbents.

Are you sure? Description says you need to reverse the hub to change gear.
