>>1838420>Those motorized bicycle kits are notoriously unreliable. Get an ebike.They can be but it takes a investment of time and about $20 worth of parts the Big issue with the kits is in the assembly when you buy one it is guaranteed that either the crankshaft was installed without any lubrication the wrist pin retaining clips were not properly installed or the spew from the making of the parts was not fully removed.
so if you take the time when you first buy one of these engines to replace the main seals, replace the wrist pin clips with ones for a chain saw and inspect every part for spew. a two cycle gas engine can be reliable. Secondly only a retard puts one of these engines on a bike that was not designed for it
