Hi,Andy! If you're a big guy(over 6'0" ),you might want to go for the Avanti line,although I'm holding off on one until they satisfy me on their trannies.I don't think the `Autopower' has the `lock-up'problem like some of the `Supersports'.Ask Ivan on this forum about the `Stinger' or `Autopower'.They are definitely for bigger people.The Tomos is fine,but just a little small for my needs.If you're of average size,they would do fine.The long-legged type though needs the Avanti for maximum comfort.IMHO,that is.
