NOTE: The Harbor Blue frame has wheels that are not color matched and are a lighter regular blue color.

NOTE: The latest version of the Screaming Demon updated the design of the gas tank cap so that it is slightly loose when screwed on fully so the tank can be vented to allow proper fuel flow.

NOTE: The rear sprocket included with Zeda engine kits is not compatible with the Screaming Demon mag wheel. We do offer a 44 tooth sprocket for the mag wheel which can be ordered separately (ENG2S66-SDBHP).

  • Screaming Demon Combo

    Posted by Tom D on Jan 13th 2022

    Shipping excellent, packaged fair. Front forks scratched and paint was smudged throughout entire front fork - understand the painting is done at a third party site. No spacers provided for back wheel which is mentioned in disclaimer not sure why not though. No instruction manual - easily found online. Gas cap not vented and don’t want to ride with it not entirely screwed on. Front axel retainer clips would have been nice but I just purchased some on Amazon. All in all really nice heavy duty bike. Just getting to install engine...Molly has been great with returning emails!!!
    Looking forward to a great project build!

  • Awesome

    Great staff over the phone and delivery was fast...I had issues with my back rim bolts holes being stripped but I took care of the problem with washers longer screws and lock tight ...Did not want to wait on another rim to excited to ride and it was the only one left in stock definitely felt blessed

    I've noticed 2 problems with this bike, firstly the gas tank cap is always leaking fuel. Second, the brakes are horrible. You have to have a dual brake lever if you want to ride safely, then you also need a rear disc brake as well to help stop in a hurry if someone cuts you off.
