    Cyclone motor with aluminum frame

    I bolted my 1200 Watt Cylcone 3 chain wheel to the frame with bolts going through the frame to keep it from rotating. So far it works great on my old bike. I want to buy a Diamond Back Recoil which I understand has an aluminum frame. I am wondering if the aluminum frame while hold up to having bolts through it and having the forces of the torque of the motor on it. Please advise. So far I love the motor.

    Truthfully, I would worry about putting that powerful a motor on an aluminum frame, especially if you drill through the frame. It you want to move it to a newer bike why not go with steel? You know it will be a bit safer.

    At this point e-bike conversion kits are not caught up in federal e-bike safety standards. However, if you were looking to buy a ready made e-bike with that size motor, the bike would have to meet safety standards set for mopeds and motorcycles by the National Highway Transportation Safety Administration. Any e-bike that can travel over 20 MPH or has a motor over 750W must meet these more stringent safety standards rather than the more anemic bicycle safety standards set by the Consumer Product Safety Administration (it's safety standards only apply to those electric bikes with motors under 750W or that don't travel over 20 MPH). You only have one you so err on the side of caution. Good luck.
