huh thats clever! and you can just swap the cranks round?

yea, why not, can't think of a reason, of course disc brakes are out!

Your pedals will need to be stripped and turned round to run a L/H chain. Then they will fall off during the second ride.

Aren't rear wheels dished specifically to be stronger on the drive side? (Not that I pedal hard enough to worry about that!!)

Thought they were dished to accomodate the cassette only. Strongest wheels are ones that aren't dished at all

Ah - Every day's a schoolday! Apologies for the numpty post, then. In which case, this looks like a great idea!

i did run my driveside on the other side for a bit. I used some locktite on pedals they were fine

how do BMXs get over the pedal issue when running LT drive?
Posted 2 years ago # -
I've got one on my pompino, but Im running it the normal way round. Using a xt mtb disc hub allows a freewheel single cog on the other side for a flipflop hub.
Works really well, no problems with stuck cogs or stripping the hub thread (or pondering the eternal "do i need a lockring" question)
Got mine from velosolo about a year ago, and no sign of any wear yet.Posted 2 years ago # -
flats would be ok, spds would be the wrong way for your cleats

The issue is less with the directio of the pedals than the direction of the threads. The left hand pedal has a left hand thread for a reason, it will unscrew otherwise. The way to do a 'proper' left hand drivetrain is to use tandem pilots cranks. They have the pedals threaded 'normally' but the spider is on the left.
Bolt on disc cogs are a much better idea than left hand drivetrains.

You guys seem to be missing the point. You use a FRONT disc hub, replace the axle (longer) and spacers (wider) and run it as a rear fixie hub with the drive on the same side as usual = no lockring, no dish.

thats the way LFG and VeloSolo do them

back to the snow bike,, it seems he has the same spacing on the front and rear as the wheels are interchangable,, so he has two different ratios avalable
is a fixed wheel the way to go? would be a right pain in the shins pushing a fixed wheel bike in the snow
but then again would most freewheels eventualy freeze up

He doesn't have bolt on sprockets on the snow bike. He's running two rear wheels, both with a freewheel (or cassette wheel with spacers) and a disc. Pretty standard for snow bikes nowadays.

Thanks for that - I'm putting together an electric car for the greenpower car project for a groups of kids at school. I've been looking to have some sprockets custom made to run attached to the rotor attachments and these guys look like a good placed to size.
