Samger 49cc 4 Stroke Petrol Gas Motor Kit Engine Bicycle Conversion Kit for Motorized Bike

A perfect kit fitted right and is a good upgrade if you don’t want to tinker with a two stroke like i did the only problem I had was the clutch burning out but sent an email and they sent me a replacement straight away

Good little engine. Very fast for its size as it can haul me at a good 38mph or 61kmh however the gearbox didn't last long before the bearings gave way but after buying a replacement and it performs as good as new.Also has a very good mpg consumption. Also i would recommend that you grease the chain in the reduction gearbox regularly to get the most out of it.Also have a spare clutch handy as the one supplied with the kit wears down after 300 miles of use.

Very good, easy installation, I recommend buying better quality screws for the base of the motorcycle, to prevent the motor from moving backwards and do not loosen the chain

This is an amazing kit, with everything you need.

Excelente product

No plans but still good hopefully will work still trying to shorten the chain . All the parts you need but the cranks are not wide enough to clear the bike
