    Being that i have just been enlightened that my gas powered bike is not legal...only elec allowed with a max of 500 w.
    Wanted to get the ETEK but have not seen this rating...anyone know?

    Canada... yes... 500 watt limit.

    You could move to America and get 750 watts.

    Or become an "outlaw" and go above and take your chances. :thinking:


    The Etek produces massive power... like ten times your limit... I'd advise either a low powered hub motor or a DIY project using a small motor. If you have enough money you could look at the Cyclone motors. The Etek also weighs above 22 lbs while the smaller scooter motors are about 8-10 lbs.

    You get a lot more "bang for your buck" if the 500 watts goes through multispeed gearing because then you can use the lower gears to climb hills and the higher gears for speed. 500 watts isn't that bad if it's used correctly.

    My chrome stretch has a 600w front hub...ssh, it has no markings so how would they know what size it is.
    Ran across a kit that attached to the pedal chain allowing use of the bikes gears and mounted under the frame between the crank and rear wheel, but i can't find it now.

    I wish there were more options... Cyclone is the only kit that I know of...

    If you already have a 600 watt front hub motor you ought to just use that.

    If you want more speed and power you could overvolt it slightly.

    Not to the chain to my knowledge. I might be wrong, but I think the Curry kits attach to the rear wheel through something that intertwines with the spokes. It's a direct drive to the rear wheel... so you don't get the multispeed advantages of going through the chain. (it's the same as a hub motor effectively)
