A new head cap design is also added to fit a spark plug in a 45 degree angle giving it a slimmer profile. This engine kit creates less needed head space for mounting on a bicycle and has more torque and power compared to regular 80cc engines. The head cap can also be turned 180 degrees for a preferred forward look. 

Angle Fire Black Flying Horse 66/80cc Bicycle Engine Kit:
This kit is the same entry level kit with all the same upgrades and performance specifications as that offered with our Silver Flying Horse 66/80cc Bicycle Engine Kit model. Only difference here is that the engine kit is painted a glossy black. To add to its appearance, all parts are painted separately and then assembled to insure that all components are painted properly and evenly. So if you're looking for a high performing engine but want the added touch of the black paint, this may just be the perfect kit for you!

Grubee SkyHawk 66/80cc Angle Fire Bicycle Engine Kit:
The latest addition to the Grubee family of bicycle engine kits is the Grubee SkyHawk with the Slant Head/Angle Fire head cap. This kit is essentially a tweaked version of the above mentioned Grubee SkyHawk 66/80cc Bicycle Engine Kit. It is the same engine as the standard Grubbe SkyHawk 66/80cc engine but instead of the spark plug pointed straight, it is angled at a 45 degree angle. This creates two added benefits:

1. The slimmer profile requires less head room for mounting on the bicycle
2. Due to the added compression created by the angled plug, the engine creates slightly more torque and power compared to the regular, straight head engines.

Just like all of our other Grubee SkyHawk engines, this kit comes with extra spare parts and components which include and extra head gasket, spark plug, spark plug cap, two head studs and two muffler gaskets.

4 Stroke Pull Start 49cc Bicycle Engine Kit: (Out of Stock)
Want the added reliability and less smog forming emissions with a 4 stroke engines? Unlike the 2 stroke engine, the 4 stroke engine does not require you to mix the oil and the fuel together. And because of this, there is far less emissions with the 4 stroke engine compared to that of a 2 stroke. It features an independent oil reservoir which keeps the engine well lubricated. Due to this, the 4 stroke engines are know for their reliability and long life.  Further, this kit features a pull starter with an added centrifugal clutch. With this centrifugal clutch feature, there is no need to fumble with engaging and disengaging the clutch manually like the 2 stroke engines. Similar to an automatic transmission in a car, when you pull the throttle, the clutch will automatically engage and set you going. Once at a standstill, the clutch will automatically disengage the engine and the engine will stay running at a stop.
