bike pusher trailer

[Odonnellp24]

I may be on the wrong forum for this...:toetap05:
So for all you tinkerers out there, I've got a fairly nice old mountain bike that I want to motorize but I dont want to start welding stuff to it. I've seen motorized pusher trailers and I'm wondering if anyone has any experience building/riding or photos so I can get an idea of what I want to do. Also any advice would be welcome. I'm split between a single wheel and a 2 wheel design.

Thanks

I've seen a few different styles on YouTube.

does it have gears? you could buy a 49cc kit for it.

you could get one of them chines 66cc 2 stroke bike engine kits from ebay, and what they call a shifter kit from sickbikeparts.com, it should all just bolt right on.

if you want one of those push trailer things, it shouldn't be too tough to make. personally i don't really like the push trailer, but i guess it works. go to motoredbikes.com, you can get info there.

Got my engine today! I was originally gonna go with the HF 2.5 but this one was only another $40 and nearly 3x the power. A wise man once said "Theres no such thing as too much power, only not enough traction." Do I see a torque converter in my future?

Found this one on youtube, I'm really digging the trailers suspension. 60mph, this guy's insane.

I built a cart with one and it has no problem pushing me (~230#'s) and its fast even with the governor installed (for my kiddo's sake). So far in the short time I've owned one it's started on the first pull most of the time and always on the second and third. Even right out of the box. I'll be sure to tell how it stands the test of time.

Thinking about how to rig some kind of braking system. I could change the engagement speed of the clutch down to a low rpm and use that as a compression brake (easiest). An obvious downside to that could be much greater clutch wear. I've seen moped rear wheel assemblies with the sprocket and drum brake installed and I could run another brake cable. Then I have 3 brake levers to worry about plus a throttle....

I know this thread is a little old, but I'm wondering how you are progressing on your pusher. Did you decide on a one or two wheeled pusher?

I have some experience riding both one and two-wheeled pushers. You don't need a brake on the pusher if your mountain bike's brakes work well. Last summer, a friend of mine and I rode our pusher-powered bikes from the border of Illinois north to the Michigan border. It was about 380 miles and it took 3 days.

His is a one-wheeled pusher. Mine is a two-wheeled pusher (yellow in the image).
