SMALL 26.2cc 4-cycle engine - will it power a bike?

[ZnsaneRyder]

I found a cheap deal on some really small 4-cycle engines, and I'm wondering if they will have enough power for a bicycle. They go to 26cc 4-cycle MTD weedwhackers that are on clearance.

The engine and clutch was easy to remove to use for a project.

I'm hoping so, because only 26cc should get great gas mileage, and you never need to mix gas and oil.. I want to stay with 4 cycle for ease of use. My bike trailer with a 4 cycle 196cc engine gets 100MPG, I'm hoping a smaller engine on the bike can get much more.

They already come with a clutch that you can weld on your sprocket or roller of choice.

My friend bought one for his gas skateboard I'm rebuilding. The little engine will drive a jackshaft that drives the right wheel. I know it will have enough power for the skateboard, I just hope it has the power to also use on a bike.

Is 26cc with a 4-stroke strong enough to make a motorized bike?

It will do it - but you will be assisting on hills although you'll get a fairly good top speed on the flat. MOST important is the right gearing, the smaller the engine the more you have to stay within its power band. Id recommend either a belt or chain direct drive of some description as that means less driveline losses

GREAT!

That's good news. If I can put one on the bike, I'll try to aim for 30MPH or so. I'm so glad that mini 4-strokes have hit the market now and no gas mixing needed on small engines.

Thanks.

How much are you paying for it?

Who makes the motor?

They will work but probably be a little slow

You should get 175 + MPG

Staton sells a friction drive with a Honda gx 25 and
of course the Honda gx35 cc

Staton-Inc friction drive kit. This is the Honda GX25 25.3cc 1.10 max hp, 4 stroke, (no mixing of oil & gas and very quiet) bike engine kit.

These engines get from about 160 to 220 mpg.

I just bought a Honda gx 31cc engine for $50 and its going on a friction drive

I have to say that I will always prefer 2-strokes for machines like this. My grandfather used to say 'the right tool for the right job' and in this situation with sub-50cc motors I think the 2-stroke is perfect. Mixing petrol/oil (and in my case a soupcon of Nitro) is little hardship when you consider that a 2 stroke can provide twice the power compared to an equal sized 4-stroke.

My bike will top out at 35mph from 32ccs. Augi's machine will make 38mph. I dont think there is any 32cc 4-stroke will provide those figures even if it was insanely tuned.

For volumetric efficiency and simplicity, in my personal opinion, the 2-stroke wins hands down.

Good luck with getting your machine built and we want to see pictures when its done

There are a lot of people that think the same way.

IMO, 4 stroke trimmers and hand held blowers are inferior to their two stroke counterparts. They are heavier, less powerful, more complex than they have to be, and more expensive. This is why two stroke engines dominate in this area. (until they are outlawed by the misguided eco-weenies)

the 4 strokes are cleaner and use less fuel, but have less power. The eho35 performs wonderfully. I top out at 28.

I'm getting close to 30mph out of my belt drive 31cc 4stroke clone, with a slightly higher octane fuel mix, and I'm a large rider. Cheers Martin.

Not legally, astring! Let's not be reading about your "in-car-ceration" in the Legal Issues forum.

The small 4-stroke would probably be best with friction drive.
