    Wonderful kit! All the bolts are tough and everything fits together! Would buy again!!

  • Zeda 80cc with the reed and oko carb best combo yet. First run got it started with no hesitation, a little tuning to the oko carburetor and you’ll be flying

    My kit came with a frayed and binging throttle cable. So I called and sent a picture and they shipped out a new one the same day ! This is a great performing engine for the price !

    Posted by dalton destefanis on May 18th 2020

    Just got this motor and I’m excited and very happy how it looks and upgraded parts it comes with , only thing that worried me is the exhaust studs go in so far and then it gets hard to tighten and there’s a lot more space to go but other then that it’s perfect

    I purchased an engine kit and I have to say that the quality of these kits are exceptionally good compared to the other company’s out there I was impressed with the 8mm bolts and Allen screws very sturdy. I have been building bikes as a hobby and have used other kits and they have just been a disappointment to work with these kits here are the real deal. Don’t wast your time and sanity buy quality. Also the customer service is excellent buy far compared to the other. These kits will be my go to for my builds.. thankx Bic eng .com... joe g— mr.g”s custom bike works...
