sprocketless drive, sans chain?

    Is there such a thing as a gas engine kit which doesn't use a chain and sprocket, but instead uses rubber "rollers" which contact with the rim? Sorta like a brake, but with the reverse result.

    I believe you are talking about a friction drive setup?

    If so, there is a friction drive sub forum on the site here, with a ton of information!

    I think there were a few attemps at as friction drive rubbing only the rim . I have seen an electric one, myself. It was " pitiful !"
    Friction drive roller on the tire is a better idea & has been around forever.

    There was a member here named Retmachinist, I believe. He frequents the other MB forum, and had installed a lawnmower engine which rubs the rear tire's sidewall for friction drive. It looked pretty fast on the youtube video.:detective:

    Google him.

    Excellent! The problem with Google is that unless you know what search for, you won't get the desired results. ^%^#%&@, I spent a long time looking for that, all I needed was the term 'friction drive'. Thanks! :)

    that's counterintuitive, wouldn't the flat surface of the rim be preferable to the squishyness of a tire?

    well, a rim-driven friction driver would require two fairly small drive rollers as opposed to one larger roller... there's a LOT less mechanical going on with a single roller, and powering the single roller is a lot more direct than two on the sides
