Goplus Bicycle Motor Kit 80cc 2-Stroke Bike Gasoline Motorized Gas Engine Bike Motor Kit (Silver)

The media could not be loaded.  ran for a second but the clutch stopped working and the chain tensioner broke but that’s most likely my fault for the installation. very good for first time builders. very customizable. overall pretty decent for the money

The box was missing the hardware for mounting the gas tank and I also had to order some after market parts to mount the motor. The motor mount issue is due to my bikes frame thickness and configuration (forward pedal axle). Also, my bike is a 12 speed with caliper brakes, so more modifications will be needed to install a clutch next to the brake lever. The gas tank was dented on the bottom and all of the mount screws had to be bent into the correct position. That’s as far as I have gotten. Seems to be a lot of hurry up and wait when it comes to all the obstacles and missing parts. I haven’t finished the build yet, so I’ll post a final review later when it’s finished.The bike is a traditional 12 speed cruiser.

He comprado dos motores y los he enviado para mi pais, Cuba, para montarlos en bicicletas ya que la crisis de transporte alla es tremenda, el resultado ha sido muy bueno, mis familiares lo estan usando desde hace mas de un año y tienen la mejor opinion, son fuertes, economicos y faciles de instalar. Solo que hay que mandarlos desarmados en piezas y en varios envios para que entren como piezas de repuesto, ya que si llega armado la aduana lo decomisa sin derecho a reclamar.

You need to know how to make some changes to make this work. I had to change the fuel line because it was leaking after my fist ride. You will have to bolt the muffler to a 2x4 prior to putting it on the bike and heat it up with a blow torch to bend it to fit under the peddles. It is very fast and the next bike to get would be one that has a peddle break and a hand held front break so the kids can ride it without getting confused with 2 handles on the left side, Overall I am ordering another one. Have fun and keep the rubber on the road!!!

It had scratches on it and something was wrong with the motor internally. Had to work with it to get a spark. It seems used.

Overall, pleased but there were some adjustments needed to install. For example, one of the exhaust manifold mounting holes on the engine had to be retapped to clean the threads. But everything went together just fine. Instructions were just OK but there are lots of other instructions on the web that helped. Finished bike is a lot of fun to ride and always gets second looks from people.

Well my brother received it as a gift it took him about a week to work out the glitches, but he was happy with the overall performance. Except needs more rubber between the mounting screws and bike. They kept loosening up and that frustrated him.. Rubber washers and lock nuts maybe. Good for beginners

Well, my bike goes 28mph, so it's a win. That said, the install is going to be a lot of trial and error if you're new to engines and mechanical assemblies. Tip, throw out the lockwashers and buy good ones for a few bucks, it solves a lot of the loosening issues.

I was riding on the road thanks god it was a long flat road but the instructions are very bad but back to the point I was driving and the throttle flap in the carberator wasn’t moving and I couldn’t stop so here I was going full speed down the road and I remembered that there’s a kill switch so I pressed it and it doesn’t work I made sure I put the right wires in the cdi so I eventually stoped by the motor stalling witch is also a pain in the a$$ but I noticed one of the wires is snapped in the cdi wires from the kill switch in general the parts are cheap the instructions are crap and the gas was leaking a lot so for the money I think that I should get a refund + keep the bike

Great product. Quick delivery. Very pleased. Would order again.
