80cc Engine

Hey guys im new here and I want to install an 80cc engine on my Specialized hardrock mountain bike. Its an older model... maybe like 1994-1996 and I was curious to know if the engine would work.

Thanks!

Garrett

Welcome Garret.
Somewhere on the site or someone can tell you the L,H,W needed.
What size is your bike ?
Where there's a will there's away. Good Luck,

Hello Garrett, Welcome to the forum

Most 24" or 26" bicycle with diamond frame and horizontal top tube should have sufficient space to mount motor.

At least 12.5 inches running along the seat tube from the top of the bottom bracket to the bottom of the top tube.Tubing size from 1-1.5inches on the both the seat and down tube. Plus or minus 70deg. above the bottom bracket between the down tube and the seat tube. Inner distance between pedals needs to be greater than 4.5 inches in width to clear the 4.5inch wide motor.

there are no 80cc engines. sue them for false advertising.

Those bikes make great solid mb's

ok... i think my bike is a 26 inch becuz it says 26x1.25 or something on the wheel. Ill take a picture of it and post it.

it's most likely a 19" frame / seattube; it'll work great!

ok, do u know if i can adjust the handle bars on a bike like that?i want to raise them up a bit becuz it feels like im riding a crotch rocket haha

You can raise the gooseneck a little on most bikes, but you'd be better off just putting on a set of bars that feel right.

I'm looking at photos of your bike and I think it's gonna be a squeeze to fit the engine in there.....I may be totally wrong but I would check measurements.
