I don't know for sure, but I don't think its referring to a .75HP engine, that would be tiny. It's probably more along the lines of a 3 or 4 HP.

I've seen those plans on the net before, a 3/4hp engine.. tiny! its just like one from a model car or boat

there is a really great website, http://members.tripod.com/jleibovitch/id32.htm which just has heaps, and heaps of mini bike picutres and a little story to go with each.
One bike on there is the 1/4 SCALE MINI BIKE

If youre going to build this, instead of using a 3/4 horsepower engine, you should use one of those engines the have on gopeds.

I have a couple of these, and I have had a great experience with Zenoah engines. There made in japan and they are awesome cause theyre really easy to modify, make tons of horsepower for their size, and the can rev to like 10000 rpm in stock form. One of these would go great on that minibike

I know it sounds like I'm trying to sell these things, But I'm not, I just really like these little engines.

oh yeah, and theres another brand on this website, called Chung yang or CY, these are decent but not as good as the zenoahs

Heres a link for ya in case youre interested:

Cheers for all the help guys! i might have to redesign my minibike, i have a 1.3hp 50cc engine, but for some reason it's ****ing huge and weighs a ton. So i might need to go for the bike frame idea, and maybe use a childs bike, to keep it as small as possible.

Okay, I know this is an older thread, but I wanted to revive it because I am seriously considering building one of these for myself, regardless of the fact that I already have several "store-bought" (okay, craigslist-bought) pocketbikes. I was originally considering using the pocketbike wheels, but those things are pretty big compared to the ones recommended on the plans (90/6.5 and 110/6.5 on the regular PB wheels). I do have a spare 47cc pb engine with a centrifugal clutch and a 6th or 7th pinion, so that will probably wind up being the powerplant. The standard pb pinion and sprockets run #25 chain, I was thinking maybe doing the jackshaft setup as well for lower gearing and more torque - possibly running a 68th sprocket on the rear wheel, but not sure on the jackshaft yet. I'd like to get one of the small barrel tanks like is shown in the plans, but if all else fails, I've got a couple of spare pb tanks that I could fab a couple of brackets for mounting. And, because I have several pb's already, I also have at least a good 3/4 of the parts needed for one of these bikes - all I would really need is the materials for the frame, jackshaft, and wheels.

On one of the sites above (http://members.tripod.com/jleibovitch/id289.htm - thanks for that link, MMB!), I was considering building mine like the second bike, the one from Alan Henderson. What do you guys think? I'm open for opinions, suggestions, sarcasm, donations to the cause, chocolate chip cookies, and so on.

(Before all of this, however, I need to pick up a welding rig - might make things a bit easier!)
