ZTMoto Phantom 85 Bicycle Engine Cylinder Kit

These parts should be made with a more durable and stronger material so good customers like me don't have to spend tons of money and time just to make it run for 2 miles wtf put some money into your product to make it batter and it'll be worth it stop being cheap

So far so good with the replacement . I'm half way through breaks so it beats the 7 day an 1 day failures . I just wish the company would make a fix for the walking needle bearing . As there are other alternatives an your prob losing money. Only flaw I see other than that it's a bad azz lil engine . Respect it

I am very satisfied thanks for listening to your customers....
BICYCLE ENGINE...Always delivers consistently on good quality at affordable pricing

Arrived in good shape and happy

I'm in the brake in period and 2nd time, but the piston or bearings were not the problem, it was debris in my casing and did not blow it out, before brake in, they sent new piston kit and so far so good at 20:1 my first time was 40:1 and I can tell big difference already, so I will give it a 5 star rating unless engine blows again, which I doubt will happen , will keep you informed, oh and theyBicycle engines made good thus far thank you

Bicycle engines.com always stands behind the products it sells

I have bought 2 so far and they work great.
