I'm building a motorized bicycle. I'm using a Zeda80 with a ported cylinder. I'm using a Huffy NightHawk. It'll have a 36 tooth sprocket. I weigh about 140lbs. What do you think the top speed will be?

My Skyhawk with only mild mods and an expansion chamber with a 36t sprocket will hit 44mph, according to GPS, when the carb is dialed in (carrying my 200lb carcass). Make sure you add front brakes to your build!

I'm the one in the lime green shirt. Speed visualized at around 13:58 in the video.

Best of luck in your upcoming adventures!!

It's hard to guess without seeing a very specific setup but probably around 40 MPH on flat roads assuming the Zeda engine can handle that small of a sprocket. It's reasonable to expect the low-end torque to be pretty low. Steep inclines may be a problem with that small of a sprocket.
