Assembly Instructions

The Zeda 100 Max is a brand new addition to our Zeda 100 lineup. This newest model still has the power and performance you’ve come to know with the Zeda 100, but now available in a 2 piece cylinder and head design. The Max also features a thicker more durable cylinder and larger fins on the head for improved cooling. This cylinder also comes with open transfer ports that help optimize performance. With a separate cylinder and head, you have more potential for upgrades.

For the ultimate upgrade check out the CNC Pro Max Cylinder head with dual spark plugs.

New Features Include:
  • 50mm bore two piece cylinder/head (increased weight capacity, lower operating temps, easier starting, sustained power output across varied rpm range)
  • High performance Speed carb
  • Silver anti-corrosion coating
  • High performance CDI with Yamaha components
  • Improved magneto
  • High end allen bolts
  • Improved gas cap

This bike engine kit includes all of the necessary items to turn your pedal bicycle into a motorized monster! Supply is very limited, so get yours while they last.

    I’d recommend this kit! Had a small issue on arrival but customer service fixed it immediately. They are awesome! The engine and components are of good quality. If you’re looking to order this, I’d say just do it. You won’t be disappointed. I will be ordering again. I’d recommend over somewhere else just for the great customer service as well.
