Front wheel mounted motor too

[Member 28982]

Would the front fork need to be modified to fit a sprocket?

Would depend on the fork, some have more clearance then others, think there would be just as much clearance as the rear stays...........Curt

It may accelerate faster with a nice powerful little 2 stroke, since instead of pushing its pulling on the front. Might be able to use a mag wheel with the 6 hole and use one of those type sprockets.

Seen it done before with sprocket and chain on the front wheel, didn't look to difficult. Maybe use a small multi speed hub sprocket adapter, or rag joint. ...........Curt

I've seen several sprocket drive front wheel bikes over on the other site. (At least I think I have.)

EDIT:
Here's a photo of one with a sheave and belt drive:

My guess is this arrangement would just tend to spin the wheel/lose traction more easily than a rear drive bike. Also, no wheelies.

Synchronizing the carbs would be a little challenging with two engines. But shouldn't be that bad. If you wanted a twist grip throttle, you might have to fab something up.

Weedeater motor would one of those work? I have 2 weedeater motors and a chainsaw motor. All have carberator issues but they run I put gas in the sparkplug holes. I assume the chainsaw motor would be more powerful. All are from 25cc-33cc. That clutch in the bike above where would I get one of those?

I was thinking of somehow mounting another 49cc 2stroke where my front basket is.
But Idk if I have the clearance for a sprocket / chain and i have enough tire problems ever 60 - 100 miles so friction setup won't work for me...
Is it possible?
I carry on any given day roughly 20 - 70 lbs, various things....i weigh about 200 lbs.

My neighbor got a 34cc 4 stroke for free (well basically $12 for new carb I just ordered) its a briggs & stratton. I was thinking about helping him attach it to an old green murray would probably be perfect for a FWD setup. I don't know what would be the best chain to use but I was thinking 35 chain or pocketbike chain. I could just get a sprocket welded on the clutch bell but don't know how long it would last.

Helping him with his moped projects....Lol I wish I was your neighbor

I'm rebuilding a 2 stroke for him too just ordered the bearings, gaskets and the half moon keys. I'm doing it for free as a christmas present.
