Review on 🚲 YUEWO 80cc Motorized 2-Stroke Upgrade Bike Conversion Kit with Speedometer - Ideal for 24", 26", and 28" Bikes (Black) by Drexel Wortham

These are fun little motors if you have mechanical skills and tools but the quality is very poor. Mine had a bad crankshaft seal right out of the box and the bearing in the clutch pinion was very bad. However, if you are looking for one that can be completely stripped down and are learning how to port/polish a 2-stroke engine and do piston mods, then this is your engine. They are very cheap to work with and you can get up to 35-40 mph from them you just have to work at it. All devices are cheap and top off if you don't breathe properly. Also, don't expect to build this in 4 hours, it will take a couple of days.
