Features

  • High EfficiencyThis 49cc pull start petrol bike engine is equipped a four-stroke engine, which allows for full gasoline combustion that reduces pollution to the environment, and it's more efficient compared to two-stroke ones.
  • Fast SpeedThe maximum speed of this engine is between 27-32 mph. Once your bike is equipped with this 4-stroke bike engine motor kit, it can help you save more time and effort.
  • Good Heat DissipationThis engine is air-cooled to keep the heat dissipated while operation, extending the life of the engine.
  • Low NoiseCompared with a two-stroke engine, the four-stroke technology makes the operation more stable and quiet. And the quiet running process makes it more enjoyable when riding.
  • Large CapacityThe 49cc gas powered bike engine's fuel tank can hold 2 liters of gasoline, allowing you to use it for a longer period of time with a single fill-up.

  • Engine and tank themselves seem OK, basically all the hardware is trash.
The engine itself, and the fuel tank it comes with both seem to be OK. The engine is some kind of knockoff of a honda GXH50, and seems decently built, and starts easily and runs well. The fuel tank is generic, but it doesn't leak, and mine wasn't rusty or cracked. The attached belt drive transmission seems a little questionable with noticeable runout in the pulleys, but works ok so far. The muffler required significant modification to remove a lip of pipe sticking out of the flange, preventing it being flat to the engine block surface, so I had to grind that down. Basically all the rest of the hardware in the kit is trash. The pedals came bent. The chain is coming apart. The screws, bolts and nuts fit loose, and break easily. The sprocket mounting holes are drilled off center. So yeh, good engine and tank, expect to have to replace or upgrade everything else in the kit. I have had to do so, and it has added considerably to the cost of the project. Since the engine and tank TBH are most of the value of the kit, and you'd pay the same as this for just those elsewhere, still gets 4 stars. ... show more

  • Its not a motorcycle

  • Good Engine
I love this engine. Easy to assemble for me, it runs more smoothly and very powerful than I thought. So far so good.
